From becoming more responsible to reliving my favorite stories with my children, being a parent has been a blast! While it has helped me “grow up” I have most certainly grown down. I am still new to the extremely rewarding field of being a mother. My oldest child is three years old and I have a set of twins that just turned one. I know the years ahead will bring much more adventure, but I’ve learned so much in my three years of motherhood.
Remember this stuff?
It was truly magical when you were a kid, wasn’t it? I remember watching, eyes wide with awe and wonder as we squeezed that liquid goodness over ice cream and, almost immediately, it became another form of chocolate-y goodness you could crack with a spoon and crunch between your teeth.
Then, there was that time in college one of your friends bought it for erm… off label purposes only to discover, much to her disappointment, it didn’t harden at all at human body temperature?
What? Only my friends did that? Fair enough, we were mostly humanities people, we didn’t know any better. Pays to always have a chemist in your crew though I have been warned never to play pool with physicists.
I honestly didn’t give much thought as to how the various “shells” transformed until decided to introduce it to my kids. I made my own because I didn’t particular want them eating paraffin wax, food grade or no. I’m a tox nurse and I’m well aware that a little bit of wax isn’t going to hurt anyone, but if I wanted to eat it, I’d recycle those used birthday candles, thank you very much. Some commercial grade products have already replaced the wax with a plant based oil (Carvel, for example, has done this per Chowhound.com. Smuckers, the grocery store brand I see most frequently, declined to discuss their proprietary blend which makes me think they’re either still using wax or some sort of soylent something), but then you have to stand in the aisle and read ingredients and one kid is making a break for some sugar based Star Wars cereal and the other has decided to teach himself to juggle with the eggs…
The chemistry behind the wax and oil emulsifiers is essentially the same, which is why it’s easy to substitute the later for the former. Provided you use the right kind of oil.
You ready for me to lay the science down? Here we go:
Chocolate is the other constant (there are other flavors but why screw with a classic?) in the various ice cream shells. Chocolate, by its nature, contains a fair bit of fat, milk more than dark, but even dark has a goodly bit. Why is the fat already in chocolate not sufficient for our shell purposes? I’m taking a leap here, but after some research, it seems to me that shell needs the additional emulsifier for two reasons: 1) the fats native to chocolate are are of the more stable sort and don’t change phase easily or quickly enough for the shell to be fun rather than an eternal waiting game and 2) chocolate doesn’t have enough emulsifiers to add “tenderness” to, well, itself. Chocolate melted on its own does change state but it eventually dries out and get lumpy and/or gritty. The additional emulsifier in magic shell, much like the cream in ganache, keeps it it from dehydrating and congealing.
Per Paula Figoni’s How Baking Works, oils are, “any lipids that are liquid at room temperature,” (pg. 215). Oils are usually vegetable based (canola, corn, olive). Most are liquid at room temperature. Tropical oils (coconut, palm, etc), however, are solid at room temperature but melt quickly and within a relatively small temperature window: solid at 70 degrees F, liquid at 74.
Chemically speaking, all oils are trigylcerides: three fatty acids attached to a three-carbon glycerol molecules. Fatty acids are made up of carbon chains that have anywhere from four to twenty-two carbon atoms. Saturated fatty acids are “saturated” with hydrogen atoms (they can’t hold any more) which means all of the carbon bonds in the molecules are single bonds. Unsaturated fatty acids contain carbon atoms that are not fully saturated with hydrogen; carbon atoms that are not saturated form double bonds in order to maintain structural integrity. Double bonds create stronger atoms, stronger atoms create stronger molecules and stronger molecules create stronger substances. Due to the aforementioned, double bonds are also more difficult to break and if you want to split them to force a change of state, you have to use more energy than you would to break a single bond.
That’s why coconut oil, which is high in saturated fats, is frequently used as the emulsifier in Magic Shell; single bonded as it is, it can be broken down from a solid to a liquid with very little expenditure of energy – or just a four degrees of heat. The bonds reform with a proportionately small drop in temperature, allowing the shell to harden almost upon contact with a frozen dessert (or an ice cube if you’re just testing for funsies).
When I made my shell, I subbed olive oil because that’s what I had around. Coconut oil is a little spendy and I was hesitant to shell (heheh) out for a whole container; oils do go bad and odds of that happening before I used the whole container, even a small one, were good. Because vegetable based oils are lower in saturated fat, and thus carry double bonded carbon atoms, however, it takes more energy, and hence a greater temperature differential, to force a phase change. It worked, to an extent, but it was really cold in my house at the time, cold enough to solidify even the olive oil, which meant I had to re-melt every time I wanted to use the shell (which eventually lead to dehydration and grittiness) and then the kids had to wait a good five minutes from application to re-shelling. And, as we all know, things are only magical when instantly gratifying. They thought it was cool, but not as cool as I’m sure they would have if it had been essentially immediate.
Yay for books!
Yay for chemistry!
Yay for shell!
How Baking Works: Exploring the Fundamentals of Baking Science is by Paula I. Figoni. It was originally published in 2004 by John Wiley & Sons Ltd. I have used, quoted from, and now purchased the 3rd edition, originally published in 2010. I’d be happy to share.

My four-year-old is really interested in sea creatures and in zombies. One of her very favorite water dwellers is the mysterious and lovely Sea Star (or the star formally known as fish).
In our morning search on Youtube we came across a true-to-life ‘Zombie Starfish’ mash up that peaked Ella’s curiosity. The video is from a BBC-two popular show called Nature’s Weirdest Events.
Just what is happening here? The images shows what looks to be Sea Stars actually ripping off their own limbs. If that wasn’t alarming enough, those limbs then look to crawl away, zombie like on their own. Could this be a real life undeadliest catch happening on the West Coast from Alaska to Mexico? My daughter wanted to know more. Continue reading Zombie Starfish: Nature’s Undeadliest Catch
The excitement in our household was barely containable. Anticipation, joy, and dreams of what could be all radiated from the two geeks who live with me.
What caused such enthusiasm, you ask? Was it Christmas? Someone’s birthday? An anniversary, perhaps? The new Star Wars movie?
No, my friends. It was the announcement that Barnes & Noble, in partnership with Make Magazine, was going to be hosting a Mini Maker Faire at every single store location in the U.S. Continue reading Lessons From a First-Time Mini Maker Faire Exhibitor

I have a disconcerting memory from when I was in my early twenties: I was reading an article in a magazine about how the adolescent brain is still changing and developing longer than most people realize. The article had an example which showed a photo of a woman. According to the article, adolescents saw anger while adults saw fear. I stared and stared at the photo but could not see fear instead of anger—even knowing what it was!
I was startled into realizing that no matter what stage of life I was in at the moment, my brain was not done yet. Was that a relief that any mistakes were the fault of not-full-adulthood? Or should I second guess all my decisions now? I decided not to worry about it, shrugged and put it out of my still-developing mind. Continue reading Keeping Teen Brains Safe
I have to admit that when I first heard the name of Ada Lovelace, I had to look her up. When girls and women had few options outside the home, Ada followed her dreams, studied mathematics and became the world’s first computer programmer.
It’s awesome to see so many women who’ve made vast contributions to the world finally coming to light. And it’s even more awesome that my friend, Laurie Wallmark, got to tell her story in Ada Byron Lovelace and the Thinking Machine.
In honor of the book’s release, Laure composed an acrostic poem to Ada:
A proper Victorian gentlewoman,
Determined to become
A professional mathematician.
Lady Ada Lovelace,
Of noble birth, a
Excited by the marvels of the Industrial Age.
Lord Byron’s daughter,
Appreciator of technology, the world’s first
Computer programmer and an
Laurie is one of my oldest friends in NJSCBWI (the New Jersey chapter of the Society of Children’s Book Writers and Illustrators). Our resident technical wizard, Laurie maintains the chapter website and builds the online forms that make registering for events and workshops so easy for our membership.
I’m always on the lookout for picture books with characters my daughter can really identify with. As she’s someone who has a big interest in science, I was on the hunt to find books featuring girls who also love science and experiments.
Here are three great picture book finds with science superstars who know how to have fun while learning about the scientific method and participating in the science fair. (Didn’t think that was possible, did you?) Continue reading 3 Picture Books Starring Girls Who Love Science
Sometimes the trending Twitter hashtags make lose my faith in humanity, and sometimes they make very happy. The latter happened last night when I found #ScienceAMovieQuote trending. That’s people turning famous movie quotes into geekier alternatives by replacing one word (or a few) with something more scientific.
Here’s my favorites thus far! (And yes, I included my own somewhere in there, because I’m cocky like that.)
Not spending money at a Con is very hard to do—so many cool things! But I do take business cards and look through them at home to shop online later. Here are some talented artists I saw at ConnectiCon this year:
Moss Fête: This hat shop features exceptional felt creations. Just beautiful.
Matt Becker has a variety of art, but I was intrigued by The Disciplines. All are women of various body types, ethnicities, and ages depicting the sciences. Very cool. This is “Biology.”
SkimLines: My son and I were very impressed with this young woman’s pottery. He loved her tea mugs, I loved her yarn bowls.
Mink Works: My son loved her fox print, and I loved her soup print (adorable anthropomorphic food…if you’re into that sort of thing, which I am). But these martini-glass-monsters made me squeak with delight.
Next time you’re at a Con, be sure to check out these and other talented artists in our geeky world!
“…we will bridge the connection between everyday learning and the latest scientific discoveries, as reported in our award-winning Science News magazine, and inspire more young people to pursue careers in science.”
I am a huge proponent of science literacy, and a big fan of Science News magazine. As a family, we regularly discuss the amazing discoveries in each issue. As a teacher, I have used the magazine to foster students’ curiosity about their world. The Society for Science and the Public conducted a survey and found out that 95% of teachers polled wanted Science News in their classrooms. Of course they do!
A Kickstarter campaign has begun to bring the fantastic magazine and Teacher’s Guide to classrooms around the country. The Teacher’s Guide will help high school classrooms best utilize the information in the magazine. Jump in to promote science for all.
Science experiments are fun when you can play with them, but they are more fun when you can eat them! Or, in this case, drink.
Litmus paper is used to show the pH scale in chemistry. Litmus is what chemists call an acid-base indicator. Although it’s great for science, do you have it handy in your home? Well, I don’t, and any extra step means I never get around to doing the science. For the busy (lazy) parents like me, we need a different acid-base indicator. And I love tea.
In a previous post, my daughter made me violet flower tea, which is blue but turned pink when lemon juice was added. She also gave a good explanation on how this happened. If you have some violets, it’s a simple recipe to try (and pretty! and tasty!).
How about regular tea? Tea (Camillia Sinensis) contains tannins, which can act as acid-base indicators with color: Acidic lemon juice and tea turn light yellow, alkaline baking soda and tea turn reddish-brown.
Kashimiri Tea, Pink Tea, or Noon Tea are all the same names for a distinct tea recipe from Kashmir, a region near the Himalayas in South Asia. (A quick geography lesson would be appropriate here too.) The tea turns pink! And you can drink it! Yummy science!
5 cups water
1 tablespoon semi-fermented tea, such as oolong (some recipes use green tea, so use it if that’s what you have)
1/4 teaspoon baking soda
1 teaspoon salt (traditional, but sugar can be substituted)
cream, half and half, or whole milk (Yak milk is often used, if you have it…)
cardamom seeds and star anise (optional)
1. In a sauce pan, combine a quart of water with the tea and baking soda. Let it come to a boil and then lower to medium heat for a half hour.
2. Turn off heat.
3. Add cold water.
4. Mix the tea by lifting a ladle filled with tea up about 8 inches and letting it pour back in the pan. A parent or older child should do this since it will splash. Repeat 10-20 times. This is the fun and messy part!
5. Add some cardamom and star anise.
6. Add salt (or sugar).
7. Let sit for a few minutes.
8. Strain the tea.
9. Pour in cream until the color is pink.
10. Drink up!
As you can see in my picture above, I didn’t get a super pink color, but since I really liked the flavor, I’ll be trying it again. Here is an explanation of tannins and color changes. Remember, if you have acidic water, it won’t work! What other acid-base indicators are in our kitchens? And did you like the tea?
Who remembers April 1990?
I was a junior in high school. “Nothing Compares 2 U” by Sinead O’Connor topped the Billboard 100, while the films Pretty Woman and Teenage Mutant Ninja Turtles were dominating the box office.
On April 24, 1990, the space shuttle Discovery lifted off carrying a remarkable piece of hardware: the Hubble Space Telescope, named for American astronomer Edwin Hubble. The day after liftoff, the telescope was placed into low earth orbit. By having this telescope outside of Earth’s atmosphere, brilliant images in the ultraviolet, visible, and near-infrared spectra are possible.
Today we honor this invention’s 25th anniversary with commemorative events and celebrations of the amazing discoveries we’ve had based on the brilliant images it’s sent back to earth.
I remember the news about how there were problems with the first images. Within a few weeks the cause of the problem was identified: the blurriness was due to errors in mirror construction. What’s remarkable is that the error was on the order of just a few nanometers, yet it caused significant problems in the sharpness of the images.
It wasn’t until late 1993 that the first repair mission was launched, and a series of corrective components were installed during a record-breaking five-days worth of space walks.
The difference in image clarity was amazing!
I remember the news about the corrections: I was in college, having had made several friends in the Penn State Astronomy Club. My friends had access to the first of the images coming in. For those who are familiar with the Apollo 13 story, the spirit of innovation and critical thinking rose to the challenge in a similar manner. America as a whole was rooting for science!
Yesterday, in honor of the 25th anniversary, NASA and ESA released a gorgeous image of the Westerlund 2 star cluster. The image was deemed “celestial fireworks” in honor of the anniversary.
There are events scheduled throughout the year honor this great invention. To learn more, be sure to visit the telescope’s anniversary site, the official Hubble Space Telescope site, and the Hubble’s Flickr site to enjoy the best images.
While sitting inside the loveliest tea house I had ever been in, I read their tea guide which explained that the difference between green and black tea was fermentation.
“What? No!” I exclaimed loudly to my friends, who were trying to enjoy their beverages. “Regular black tea is oxidized, not fermented! How can a tea house get it wrong!” My friends shushed me and didn’t think it was a big deal. But I wrote a long explanation on a comment card when we left.
In another tea house bathroom, they had a wall display that also stated this fallacy. I took my pen and boldly crossed out “fermentation” and wrote “oxidation” in its place. There. At least the ladies would be informed of the truth in that establishment.
Green, black, white, oolong, and pu-ehr tea all come from the same plant: camellia sinesis. Yet the tastes are different depending on the growing location, harvesting techniques, and most importantly, how they are processed after picking.
Most teas are dried in different ways with different levels of oxidation happening. There are teas that undergo fermentation, like pu-erh. Who cares? I do. If a book, company, or shop is going to bother explaining the science behind their product, get it right!
So what is the difference between oxidation and fermentation? I’m going to step away from tea for a moment to explain, since the tea videos I found are boring and/or interchange “oxidation” and “fermentation” as if they were the same thing. If I leave my metal bike outside in the rain, it will rust. That’s oxidation.
If I coat my bike with sugar and let some wild bacteria start to grow…then I have a bad example. Nevermind. Back to drinks.
Fermentation involves bacteria or yeast that eat sugars to produce carbon dioxide, and in the case of yeast—alcohol. Beer is made with fermentation. If you let beer oxidize, sadness. The difference is important! Here’s a video about fermentation and an example of making soda.
They are two completely different chemical processes and anyone who is in the tea business should make it their business to get the science correct. Science literacy and delicious tea forever!
My daughter has been fascinated by peering into microscopes since she was in preschool, but with most selling for $50+, we’ve never had the extra funds to invest in one to have at home. So when I heard about the $20 microscope from SmartLab Toys that’s built to survive wear and tear both indoors and outdoors, I had to give it a try.
While the microscope doesn’t seem much more powerful than a magnifying glass, it’s more than enough to get her excited about discovering a whole new world we can’t see until we look through the lens.
The Indoor-Outdoor Microscope from SmartLab Toys magnifies at 40 times normal size. While it isn’t strong enough to see individual cells, it certainly is enough to astonish and delight little scientists seeing things like insect legs or a blade of grass up close for the first time. In fact, the microscope comes with four prepared slides, so the second you open the box, your kids can dive right in.
Blank slides and specimen containers are also included, so kids can run around the house or into the backyard to find anything their inquisitive hearts desire.
The microscope is made of plastic, which makes it more durable and easy to carry than a heavy glass and metal microscope—in fact, it’s so portable that we took the entire kit on vacation out of state. The microscope can be removed easily from the stand and used by itself to look at tree bark, the sidewalk, large rocks, and more.
The kit also comes with a colorful book, Up Close and Personal by Shar Levine, that includes suggestions for activities while inspiring genuine enthusiasm about science. My kindergartener was more than amused by looking at toilet paper up close, just one of many fun suggestions in the companion book.
Not only does my six-year-old enjoy finding new things to examine in the microscope, the fun is contagious; friends and grownups get into the hunt with just as much excitement. The recommended age is 8 and up, but all elementary-age kids can use the microscope with a grownup’s help.
The microscope comes with three LR-44 button cell batteries. When the time comes for you to switch them out, you can easily find affordable replacements on Amazon.com. It’s worth noting that the first microscope we received burnt out within minutes, presumably due to a faulty bulb as switching the batteries had no effect, but the replacement item has lasted for multiple uses.
SmartLab Toys is offering a special deal just for GeekMom readers. You can order the Indoor-Outdoor Microscope on the SmartLab Toys web site, and use the discount code SPRING15 for 25% off through 4/30/15! With such a fantastic deal on a STEM toy, it’s definitely worth giving it a try.
GeekMom received a promotional item for review purposes.
I am not a scientist, but I consider myself science literate. I understand how studies are conducted and I have a basic knowledge of statistics. But more importantly, I actively keep up with science articles in everyday magazines, compare them to each other, and ask questions of people I know in the science fields. Being science literate means I care about how science affects my life. I also thinks it’s pretty cool.
My children are surrounded by scientists in the family: Their father, aunt, and grandfather all have PhDs in molecular biology, and their great-aunt is currently working on her doctorate in nursing. Granted, the science topics veer towards biology more than astrophysics, but as scientists, they all enjoy talking about any new discoveries.
I started college as a psychology major, not because it was better than “undeclared” but because I thought it was interesting. I ended up in music, but I still enjoy hearing about new studies in that social science. All this means is that my children consider science a part of life, not just a subject in school.
I decided to take this science literacy skill into our homeschooling group. For six weeks, I led a class of kids from ages six to fourteen on a discovery of what science literacy means. Their homework was to find a science article from a lay-person’s source, and then try to find the original scientific article referenced. This was very tough because real science journals are often expensive for libraries to carry, are not easily accessed on the web unless you are part of a scientific community, and are generally not for sale in stores. Yet, many were at least able to find the original title and abstract for their chosen article. The most amusing part of class was when the children would read the lay person title like: Alzheimer’s Linked to Lack of Zzzz and then the scientific study title, Rapid appearance and local toxicity of amyloid-beta plaques in a mouse model of Alzheimer’s disease. They came to appreciate good science writing for non-scientists.
That first class, I told the kids to choose any topic, as long as it was a current scientific study. I’m running a science literacy class again this spring and decided to narrow down the topic to health and nutrition. This time around I’ve also allotted more time for discussion. I hadn’t counted on how intense the kids’ options would be on the various studies presented in the first class. I had to cut them off just to make sure everyone had a chance to present.
What about at your home? Don’t have a couple of PhDs to pass the potatoes and ask a question about the validity of the latest diet craze? Start reading good science articles. Science News is by far the most accessible, varied, and current science publication. Regardless of your educational background, you will be able to understand and get a quick look at the most recent and groundbreaking work in a variety of scientific fields. Read one of the shorter articles aloud at dinner and start a conversation about possible life on the moon of another planet, how robots are learning like babies, or if obesity is linked to too many hours playing video games.
Here’s a short checklist for evaluating science in the news:
-Who funded the study?
-How broad was the sample (people of different ages? genders?)
-How many people?
-Was it a blind study? Double blind?
-Did the reporter tell you about other similar studies to compare?
-Did other scientists review and comment on this study?
Science shapes our culture, politics, and personal health. Read about it, talk about it, become more science literate with your kids!
SciGirls is back this April with six brand-new episodes! As recent new fans of the PBS Kids show, which features real girls showing a real love of STEM, my kindergartener and I can’t wait to see what new science adventures are waiting for them in this third season.
The theme of the new season is “citizen science.” Here’s the latest info about what that means for the SciGirls:
Citizen science is the hottest new STEM frontier that engages the general public –and kids! – in real science. Scientists worldwide invite ordinary people—like the SciGirls—to observe and record data about everything from birds to beaches, monarch butterflies to maple trees. The data is then shared with scientists, who use it to generate new scientific knowledge.
New episodes premiere in April on your local PBS station, so check the listings to catch the girls in action.
The new season will also will also be available online nationwide starting April 15 on the official SciGirls web site.
Whether you’re looking for videos to catch your homeschooled teen’s interest, browsing for something to occupy yourself for a few minutes, or you’re a lifelong fan of learning, it’s always fun to tumble down the YouTube rabbit hole.
Thanks to some incredibly talented science communicators, you and your kids can dive into subjects like physics, astronomy, and more, and find experiments to take science off the screen and into their own hands. Here are four YouTube channels for those who wonder how the universe works—which is everyone!
Crash Course Astronomy
Phil Plait, also known as the Bad Astronomer, is no stranger to the geek world. When he’s not busy with the Bad Astronomy blog on Slate, he’s often spotted at conventions like San Diego Comic-Con. Recently Plait teamed up with Crash Course and PBS Digital Studios for the new YouTube series Crash Course Astronomy.
Plait’s “f***ing majestic” voice (according to one impressed commenter) clearly and quickly leads you through topics like moon phases, eclipses, the basics of astronomy. Stylish graphics and high-res images make each video exciting and engaging for anyone who loves to gaze up at the stars.
Dianna, an MIT physics grad, calls herself the Physics Girl. In her easy-to-follow videos, Dianna addresses everyday questions that you might otherwise not have spent much time thinking about, along with exploring the mysteries of the universe. Why is our image flipped in a mirror horizontally and not vertically? Why is the universe flat?
Physics Girl also shares her experiences with being a woman in physics, including her time at MIT, and chats with other interesting scientists in her field.
Cathé named SciShow as one of her secret YouTube affairs a couple of years ago, and it’s easy to see why. Hank Green and other knowledgeable hosts share the answers to some of life’s burning questions in quick chunks, like why does mint taste cool and why we have baby teeth.
SciShow also dives deeper into current science topics, such as the recent measles outbreak, and host Hank Green even sat down to chat with President Obama at the beginning of the year. It’s easy to spend hours browsing the fascinating content of SciShow.
If you’re more hands-on than just eyes-on, or you’re looking for experiments to do together as a family, Sick Science from Steve Spangler Science is what you’re looking for. There’s no talking in these videos—just quick how-to’s for putting together eye-catching science demonstrations that are sure hook anyone with an interest in science. You can also find other science demonstrations by Steve Spangler on the channel, which is always entertaining.
Someone recently mentioned to me that I hadn’t written a good old-fashioned meteorology post in a while. So, here’s a fun topic for you, one that you can show off to your kids if you can catch it at the right time. I’m taking a bit of stretch here, since this topic overflows into biology, which was never my strong suit.
While many of you in the northern United States have been struggling with record snowfall and record cold temperatures this winter, along the Gulf Coast of Florida the precipitation will be in the form of rain. In fact, Nor’easter storms typically form just off the coast of Texas between about Brownsville and Houston, and in their infancy those systems will dump quite a bit of rain here.
When the excess rain saturates the ground, plant life will adapt accordingly. One of the ways some plants will adapt to the excess available moisture is through a process known as guttation. I know, a funny word, right?
Guttation occurs when a plant has turned off its transpiration processes, usually at night, so excess moisture cannot evaporate from the surface of the leaf. Instead, root pressure will cause the moisture (along with other chemicals and sugars indigenous to the plant, known as xylem) to get pushed out through the leaf edges. Because of the tapering at the top of a blade of uncut grass, a larger droplet often forms at the very tip.
Guttation is not dew. Dew is atmospheric moisture condensing on colder surfaces, and is pure water. Guttation is moisture secreted from within the plant itself, and contains xylem sap.
I have seen guttation year-round—so long as the air temperature is above freezing—in every state I have lived in during my adult life*. It’s more likely to occur during a period of excess rains, such that soil is saturated. The large droplets on the tips of the blades occur most often on uncut grass, so your lawn’s first growth in the spring before the first mowing is a good time to look for it. If you’re near a wild field or meadow, that’s a good place also. It happens most often at night, so you’d need to catch it close to sunrise. The moisture will evaporate quickly once the sun hits the surface.
*If you’re wondering what states I have lived in since age 18, they would be Pennsylvania, Louisiana, Ohio, North Carolina, Nebraska, Florida, and Colorado.
The next time you see moisture on your lawn, check to see if it’s guttation instead of dew. This can make for a great lesson for kids, too. Ask the kids to talk about, write about, or draw what they see. Other topics that can be further discussed with guttation include:
• Evapotranspiration: One of the processes in the water cycle.
• Krebs cycle: How a cell can release energy from organic compounds into energy necessary for sustainment.
• Colony collapse disorder (CCD): Guttation might draw up water that contains neonicotinoid insecticides blamed for killing pollinators such as honeybees. Studies have shown that this contributes to sudden disappearances of honeybee populations in North America. Read more from Laura about other contributors to CCD.
The photos in this post were taken on February 8, 2013, in Navarre, Florida, about 20 miles east of Pensacola on the Gulf Coast. I had to lie in my front yard with my camera’s telephoto lens on manual focus. We had heavy rain the previous day. This was the same day the northeastern U.S. started to experience the “Blizzard of 2013” (February 8-9, 2013).
You might be the parent of a science nerd if the following 10 things go on in your house:
1. You come home from shopping and the following conversation occurs:
Parent: Why is there dirt baking in the oven?
Child: I’m sterilizing dirt for science.
2. You tweet, “I wonder what construction is happening upstairs but I’m too afraid to ask.” Your child responds to the tweet with: “Oh, that’s just me shaving my magnesium block.” (You know, as you do.)
3. You walk into the bathroom to see the following:
4. Your child never uses the generic names for household items. It’s always things like: NaCl, Na2CO3, 570–590 nm, etc.
5. You hear an, “Oh, crap!” Followed by running footsteps to the bathroom. Followed by somewhat calmer footsteps descending the stairs. Followed by, “I think I need to go to the emergency room.”
6. You tell your child, “Hey! You dropped some of your science on the floor. You need to clean it up.” Upon showing your child where, in a very dire tone they respond, “Oh. That’s not good!” Upon your child learning someone stepped on it, the following is said in a very serious tone, “You should probably go to the doctor for that.”
7. You ask your child what they are making, and they respond with some of the following in an “as you do” tone: Copper (II) Chloride, Copper (II) Acetate, Magnesium Chloride, Ethyl acetate, and Iron (III) Chloride
8. Your child has chemicals they purchased online held for weeks at Customs while they test it for drugs, anthrax, and other dangerous substances that come in a fine white powder.
9. You can’t find side burner, pots, and measuring cups because they are currently in use, because science.
10. The following happens on a regular basis at midnight on your porch:
If you are the parent of a science nerd, what are some other signs?

I’ve reviewed a couple of these titles and in the process of reviewing a few others and I couldn’t be happier with them. My son is nine years old and even though he’s not quite into electricity or physics yet, he enjoyed reading the story that taught the concepts. Even if your child is not old enough to enjoy some of these titles, it’s worth the money to pick them up to have for when they are older.
I’m a southpaw! I’ve always been proud to be in this elite 8-15 percent of the world population. Did you know that in 2008, you had no choice but to elect a left-handed president? Four of the last seven presidents are left-handed, and seven presidents total have been lefties (16 percent). Fascinating, don’t you think?
I polled the other GeekMoms and it turns out, I’m possibly the only one (out of those who responded) who is left-handed. I was particularly intrigued by this, since there are around 20 of us, and if I’m truly the only lefty that would make our group only 5 percent left-handed.
Left-handers also have an advantage in sports, particularly in baseball, since they can add an element that most players don’t train for.
I remember my parents making sure I had left-handed scissors for school each year. I also remember my mom struggling to teach me how to use chopsticks, knitting needles, and crochet hooks as a young girl. Luckily for me, I play sports (including fishing) and musical instruments right-handed. I also use firearms (for my Air Force work) right-handed.
In today’s world of spending most of my time at a computer, there’s very little that I need to do that really reminds me (and the world around me) of my sinistrality.
But every once in a while… I’m reminded. And sometimes it can be downright frustrating! Most often, I’m reminded in the kitchen. Today while making a fruit smoothie with my Ninja Blender, I was reminded once again.
Here are some other kitchen gadgets that favor right-handers:
So the next time you are shopping for your favorite sinistral southpaw, consider ambidextrous kitchen gadgets
In celebration of my 4th anniversary writing for GeekMom, I present to you my very first post, published January 22, 2011:
When I was little, I remember my mother making Kool-Aid. I have old pictures of me wearing my token Kool-Aid mustache. I even had a Kool-Aid t-shirt. I remember sometimes the Kool-Aid would seem, well, watery. Did my mom dilute it on purpose? Boy, I hope she didn’t. Sometimes, I wondered if she was sneakily reducing my sugar and artificial color. I remember telling myself that when I got older, I would never dilute the Kool-Aid!
But guess what? While I do my best to make the Kool-Aid at home to the recipe, I have to admit I water down the kids’ lemonade and fruit punch at the fast-food restaurant beverage machines. It’s just instinct, I WANT to dilute!
This diluting of the Kool-Aid is now a metaphor I’ve given to the crime of watering down — or dumbing down – answers to the questions kids ask. GeekMom Jenn posted about the incessant “Why? Why? Why?” questions she receives from her kids and in her line of work. My kids do the same thing, and sometimes it grates my nerves for sure! But embedded in all of the silly mindless “Why?”s is a jewel of a question that my sons are truly curious about. And when my just-as-geeky-as-me husband or I hear such a question we want to stop and give it our full attention!
And if it’s a science or math question? Stop EVERYTHING! Break out the props!
My husband and I had a great professor in college who has such a pet peeve about “bad meteorology”, he made up a website dedicated to debunking several of the most-basic of meteorology myths. A quote he said that has stuck with my husband Dave all these years was, “Be very careful what you put into kids’ heads because it’s very hard to get it out!”. We take this very seriously with our kids.
So when our sons asked “Why is the sky blue?”, our approaches to the answer might be a little different than non-geek parents. For a pair of meteorologists with offspring, we waited for that very question with bated breath, as if it were a milestone like learning to walk or ride a bike!
In our house, though, the question ended up not “Why is the sky blue?”
It was “Why are sunsets red?”
We got it when our oldest son was about 6 1/2 years old. Definitely a corollary to the dream question! So I’m now going to share with you how we geek parents approached this subject.
We started with rainbows. Our son knew the colors of the rainbow by this point, so it was easy to explain to him how red is at one end of the rainbow, and violet is at the other.
Then we discussed the electromagnetic spectrum. Enter a basic diagram, with the shortwaves on the left, the longwaves on the right. Our son could name many of the parts of the electromagnetic spectrum, such as X-rays and microwave radiation. We explained how red light has longer wavelengths than blue or violet light.
Our firstborn started getting a little glassy-eyed here…uh oh, it doesn’t get any simpler from here!
We attempted to quickly sum up how the low sun angle at sunset allows sunlight to travel through more of the atmosphere. The color red is able to “scatter” just as readily as the color blue “scatters” when the sun is higher in the sky. When the sun is higher, most of the atmosphere’s scatterers are receptive to the color blue. This is a phenomenon called Rayleigh Scattering. I fear we might have lost our boy by this point, but it was interesting seeing how much he did pick up from the conversation.
I remember that it generated more questions about the electromagnetic spectrum and I was so impressed with having a conversation with a 6-year-old about how many things in the world around us are traveling in “invisible” waves. The music on the radio. The remote control (or the 8-billion remote controls) in our house. The microwave oven. The wireless internet in our house. The satellite television.
Check out these links for other easy-to-understand explanations of sky color.
We, as parents, are challenged with teaching our kids the “right things”. Or at least, what we think are the “right things.” Sometimes those “right things” are contested topics such as evolution, global warming, or the causes of the Civil War. I hope to have an open enough relationship with my kids to discuss the varying viewpoints about those more controversial topics and give them the tools to form their own opinions, even if they might differ from mine.
But when it comes to math and science, I personally feel challenged to push the envelope to teach as much as I can when my kids express interest. I hope to never blow off one of their “Why?” questions, although I have to admit that can get tough at times!
If there’s anyone who knows how to make science exciting, it’s Steve Spangler. Have you seen this guy launch hundreds of film canisters on Ellen? Steve brings that same enthusiasm and love of science to the new Spangler Science Club subscription kits, which deliver kid-friendly experiments to your doorstep every month. While the kits aren’t inexpensive, the high-quality tools, detailed instructions, and overall sense of science-y fun are well worth it if you’re looking to foster a love of science.
The monthly subscription kit is packed with just about everything kids in grades K-6 need to run a series of experiments. And I mean just about everything—we only had to supply the water for the experiments in the first kit. I was particularly impressed with the test tubes in the box, which aren’t your run-of-the-mill science equipment, but instead come from a surprising source. I won’t spoil it for you, but I will say the tubes are sturdy and perfectly suited for kids’ hands.
The box includes two sets of instructions for running the experiments. One set, the “Top Secret” info for parents, includes the how and the why behind the science experiments. When we do experiments as a family, I always appreciate having info handy so I don’t have to go scrambling to Google to find the details behind what we’re observing. The text also puts the science in terms that kids (and grownups) can understand, so parents can explain concepts like osmosis and chemical reactions and sound like we actually know what we’re talking about.
The kids’ step-by-step walkthroughs not only include clear color photos and concise instructions, but also writing prompts to get kids thinking like scientists. Questions ask kids to predict what might happen and form their own hypothesis.
All instructions are laced with a sense of humor and enthusiasm, which shows kids that science isn’t all serious business—it’s actually fun to explore the world around us.
Experiments are designed to be done together with parents, along with some activities for the kids to spend some time on their own exploring the concepts. In the first kit, that meant my kindergartener had some hands-on time with color mixing by herself, taking the time to really make the experiment her own.
Every parent wants to share discoveries and encourage a love of science in their kids, but it requires a bit of an investment for a high-quality educational kit like the Spangler Science Club. Subscription costs range from $24.99-$29.99 a month, depending on the subscription plan. While you may balk at the price, it seems to be a fair cost for everything you receive each month, which includes the equipment, instructions, and shipping. There are also enough components in the box to run the experiments more than once or let siblings get in on the science action together.
If you have room in your budget and it’s important to you to encourage a love of science in your kids, Spangler Science Club is an incredible opportunity to turn science into fun family time every month.
GeekMom received a promotional kit for review purposes.
I just wanted to take a moment to wish Stephen Hawking, one of the people who inspired me to study physics and astronomy, a very happy birthday! A Brief History of Time was one of the books that “spoke” to me from when I first read it as a teen, um, several years ago, and it continues to do so today. I can’t wait until the time comes to share it with my son. My son and I have already shared the “George” series that Hawking co-authored with his daughter, Lucy.
Here is a video of one of my son’s inspirations, Neil deGrasse Tyson, talking about oneof mine:
And if you haven’t seen it yet, I encourage you to go out and watch the film documenting Dr. Hawking’s life, The Theory of Everything!
As I’m sitting hunkered down in my Colorado house while the temperatures are expected to remain below 0 degrees F for the next 48 hours, I try to remember that during weather like this, Mother Nature keeps some serious beauty up her sleeves in the form of gorgeous snowflakes. This is one of my favorite parts of meteorology—the fascinating things water can do!
About 20 years ago, in one of my undergraduate meteorology classes, I was taught the temperature ranges at which snowflakes will form their different potential shapes. I remember getting tested on the information, too.
“At what temperature ranges will capped columns form?”
Heck if I know now, but I can find out with the click of a button….this is from Wikipedia’s entry on snow:
The shape of the snowflake is determined broadly by the temperature and humidity at which it is formed. The most common snow particles are visibly irregular. Planar crystals (thin and flat) grow in air between 0 °C (32 °F) and −3 °C (27 °F). Between −3 °C (27 °F) and −8 °C (18 °F), the crystals will form needles or hollow columns or prisms (long thin pencil-like shapes). From −8 °C (18 °F) to −22 °C (−8 °F) the shape reverts back to plate-like, often with branched or dendritic features. At temperatures below −22 °C (−8 °F), the crystal development becomes column-like, although many more complex growth patterns also form such as side-planes, bullet-rosettes and also planar types depending on the conditions and ice nuclei. If a crystal has started forming in a column growth regime, at around −5 °C (23 °F), and then falls into the warmer plate-like regime, then plate or dendritic crystals sprout at the end of the column, producing so called “capped columns.”
I found the description of the specific kind of dendrite I photographed, thanks to Dr. Kenneth Libbrecht of CalTech; it’s called a fernlike stellar dendrite:
Sometimes the branches of stellar crystals have so many side branches they look a bit like ferns, so we call them fernlike stellar dendrites. These are the largest snow crystals, often falling to earth with diameters of 5 mm or more. In spite of their large size, these are single crystals of ice — the water molecules are lined up from one end to the other. Some snowfalls contain almost nothing but stellar dendrites and fernlike stellar dendrites. It can make quite a sight when they collect in vast numbers, covering everything in sight. The best powder snow, where you sink to your knees while skiing, is made of stellar dendrites. These crystals can be extremely thin and light, so they make a low density snowpack.
This morphology diagram seems to sum it up pretty well:
Here are some fernlike stellar dendrite pictures I took in Bellevue, Nebraska in January 2010 when the temperature was around 0F, and they are the prettiest dendrites I’ve seen with my own eyes (rather than in a book). I used the digital macro setting on my camera, a Canon PowerShot SD1200IS (a camera I no longer have, but it’s one of the best point-and-shoots I’ve ever used). I wish I had the fortitude to take more pictures, but it was so incredibly cold, my hands couldn’t manipulate the camera for very long. Isn’t science beautiful?
Oh, who wants the same old boring lyrics to our holiday favorites? Altering words to existing songs is a playful, challenging, and creative endeavor. It’s the fan-fiction of music. Winter and Christmas tunes are so well-known, it’s a great place to start. Here are some people who have already done so with a geeky twist:
The Twelve Days of Future Christmas created by Bridge 8, goes through a list of current science topics that are on the verge of becoming reality! “12 drones delivering…”
OH NUMBER PI
(TUNE: “Oh Christmas Tree”)
Oh, number Pi. Oh, number Pi. Your digits are nonending,
Oh, number Pi. Oh, number Pi. No pattern are you sending.
Want more math Christmas songs? Go here!
Hee-hee. This is some crazy editing. Star Trek TNG in “Make it So!”
You better watch out; you better not sneeze.
You better not cough, ’cause you’ll spread a disease….Viruses are comin’ to town.
“Catch” all the lyrics here.
This one doesn’t change the lyrics so much as it is performed in a geeky way. All electronic devices band in “Feliz Navidad.”
Pirate Christmas Carols! This is from me. I’ve written a lot of these. Here is one you can listen to with lyrics. No Ale!No Ale! No Ale! No Ale! Six months at sea with no dark, stout or pale.
So what’s does your family geek out about? Make it a family game to rewrite lyrics to a familiar holiday tune. You’ll be singing it every year afterwards!
Here’s one I wrote about my favorite Avenger…
Loki Was A Gentlemen
(To the tune of God Rest Ye Merry Gentlemen)
Loki was a gentleman when he took all the power.
His smile was quite debonair as he told us to cower.
“Sweet lady, kneel before me now, no need to look so sour.
Many thanks, this encounter’s been a joy, been a joy.
Many thanks, this encounter’s been a joy.”
I don’t know about you, but there is nothing I love more than to read about science that’s presented in an entertaining and digestible way, especially when it pertains to topics I geek out about anyway, like comics and video games. When I got the opportunity to interview Kyle Hill, the science editor for Nerdist Industries and host of Because Science, I almost fan-girled. Kyle is kind of what I want to be when I grow up…some day. No, not a Chris Hardwick lackey—though that does seem like it would be awfully fun. I’d love to be able to spread my passion for science and how things work, explain the hidden stories behind the seemingly mundane, and make sense of things that seem so much bigger than us. But Kyle Hill does it in a much more engaging way than I ever could.
At least, I’ll concede that point for the purposes of this article.
GeekMom: What spawned your interest in science, and what made you want to teach others about it?
Kyle Hill: I’ve always liked science and the natural world. I’d be that kid playing with LEGOs or trying to catch bugs to stare at them. My parents were very supportive of that kind of outlook, taking me to museums and buying CD-ROMs (remember those?!) about dinosaurs. After high school I went right into an engineering program and starting blogging for myself. Sometime before I finished my degree I figured out that I liked talking about science and explaining it more than actually doing it. During my graduate program I started submitting articles to Scientific American, and things sort of spiraled upwards from there.
GM: Can you tell us a little about how Because Science got started?
KH: From a logistical standpoint, working with a brand like Nerdist means producing quality digital content, so a video series was probably an inevitability. But personally, I’ve always wanted to do something like Because Science. I find that actually talking out loud about what you are trying to explain helps you understand it even better yourself. And I do. A lot. So that combined with my over-caffeinated delivery was a good foundation for a show. And since I find myself saying “because science” to justify my nerdery a lot, the name was obvious.
GM: What would you say to someone who says they are interested in, say, space, or how things work, but they don’t feel they are “smart enough” to pursue any knowledge or research?
KH: Our educational system seems to have a hard time dispelling the “science is too hard” stereotype. I’d bet that if you talked to our best scientists, they’d say that this passion for a subject is the most important part; working out the homework comes later. Science at its core is a systematic exploration of how the natural world works, and we are all ingrained with the curiosity to ask the same questions that science does. Don’t let this “ivory tower” facade that science has scare you off. It’s fascinating first.
GM: What is your favorite topic? What really gets you geeked out beyond measure?
KH: I love physics, especially where it lets you talk about power and energy and explosions! Physics is one of those fields that most people have an intuitive understanding of—whether or not they know the math, we have a good idea how things are supposed to move and interact. So when I can say that a punch from a “Pacific Rim” Jaeger is like having a 747 hit your face, it’s immediately understandable, nerdy, and accurate!
GM: What do you think is the most important thing a parent or mentor could do to get kids excited about science?
KH: It’s hard to say what the most important thing would be, but I’d say listening to a child’s interest first has to be up there. Children are naturally curious, and you can build and foster that curiosity by introducing them to the science that explores what they love. A love of the night sky, of insects in the grass, of a computer whirring away, these can be bolstered by introducing them to the people, books, and videos that let them get deeper involved. Let children explore, and give them the tools to help them explore better.
GM: Have you ever had any science misadventures? Has science ever gotten you into trouble?
KH: Well, there are things I’m aware of—physics and chemistry-wise—that I know I shouldn’t try. I try to steer clear of possible explosions as a rule. But when I was a kid collecting insects, I unknowingly forced a pretty gruesome situation. One day, I collected three monarch caterpillars in the park near my house. I put them all in a carrier and waited for them to metamorphize into beautiful butterflies. But I didn’t give them anything to eat. After the first caterpillar attempted to change, the other two climbed up to where it was and ate it alive. It was pretty rough. I wasn’t trying to run a caterpillar fighting ring. Feed your pets.
GM: If a younger person (or heck, even an older one!) wanted to be Kyle Hill when s/he grew up, what advice would you give?
KH: As my friend and fellow video-maker Joe Hanson (of “It’s Okay to be Smart”) says: Stay curious! I’m not a scientist, and I’ve never taken formal writing classes. I have a background in science but I’m not an expert. Any success on my part is from trying to stay perpetually curious, and seeking out the information that will help me get my passion across while being accurate. That means taking free writing courses if you’re not a writer. It means staying up to date (I am on the Internet *constantly*) and taking science communication seriously. And don’t ever think that you are being too nerdy!
GM: What is your favorite source for science news?
KH: It has to be Twitter. I have a pretty hefty RSS feed, but I use Twitter to keep track of the writers, creators, and scientists that I like directly (not institutions or brands themselves). Social media is a great way to stay in touch with the people that inspire and inform you, and for the most part they are happy to engage with you! Start taking notice of who seems to be writing/filming/speaking about all the stuff you like or are interested in and check up on them. Chances are they are still producing great content.
GM: Anything exciting in the works that we can look forward to?
KH: The beauty of the digital age is that you never quite know what comes next. Currently I’m writing and making videos, but there is certainly room for more science-y goodness in the future. TV spots? Maybe a podcast? If it has to do with science and geeking out about this universe, I want to try it!

“It’s science’s dirtiest secret: The ‘scientific method’ of testing hypotheses by statistical analysis stands on a flimsy foundation. Statistical tests are supposed to guide scientists in judging whether an experimental result reflects some real effect or is merely a random fluke, but the standard methods mix mutually inconsistent philosophies and offer no meaningful basis for making such decisions.”
Odds Are, It’s Wrong: Science fails to face the shortcomings of statistics
BY TOM SIEGFRIED MARCH 12, 2010
Read the whole article; it’s very good, and makes my head spin. If we can’t trust statistics in science, what is the basis for drugs being approved by the FDA, or the stated risks associated with everything my teenagers do, or how much pumpkin pie can I really eat before going over my daily limit of recommended fat?
That article was written in 2010, which you may think is old news, but How to Lie with Statistics has been around a very long time. That’s a book on how statistics can be used by companies, politicians, anyone with an agenda, to manipulate people with “hard facts”—a.k.a. math.
To be fair, Siegfried’s article is not about scientists purposefully fudging numbers, but how they generally don’t understand how to organize their data properly. They’re not bad guys (like certain advertisers), but still misleading the public because they don’t know what they’re doing. Maybe that’s worse.
So what can we do? How can you teach your children to understand the numbers thrown out in the media? Reading that the percentage of the U.S. population that will get the flu, on average, each year is between 5% and 20% on WebMD doesn’t mean much unless you understand how average is calculated (mean? median? mode?), what was the sample size, and maybe most importantly: who funded the research to get the data?
That last question may be a tough one to find. But understanding how statistics work, and how they can be manipulated, is doable and important. First, you might want to brush up on the knowledge. You could read Stephen King, but for something more encompassing, you need to stretch your brain. And no, I’m not talking re-reading the mind-numbing statistics textbook from college somehow still in your basement.
The free site Udacity has an accessible and comprehensive statistics course (my sixteen year old is taking it right now). There’s also The Manga Guide to Statistics, reviewed here, and the popular series take on it: The Complete Idiot’s Guide to Statistics. I like that one a lot.
The resources above are good for teens and adults. For the younger set, it isn’t hard to bring up how statistics work because they are everywhere, everyday. Next time a percentage of something is thrown out as evidence to do, or not do, (buy, or not buy), explain to your child what that number means, and how it could have been manipulated. Make them aware that just because math seems straightforward, using statistics may not be.
To make it fun, have them conduct a survey with their family and friends. It can be about anything (“what’s your favorite pie?” at Thanksgiving, for example.) Your job is to help them word the survey to get simple results. Then, help them make some fun graphs and play with their data. That hands-on manipulation is the best way to learn. I did it with my own kids. We asked people about tea! You can check out all our fun graphs here.
Hopefully, by the time they become scientists, their understanding of organizing data will be enough to trust their research! Especially if that research tells me I can eat all the pumpkin pie I want. Let’s all become more science literate by understanding how statistics works.
When my daughter and I went to GeekGirlCon earlier this month, there was a science area. My daughter’s favorite experiment in the science area was extracting DNA from fruit. She enjoyed the experiment so much she decided to replicate the experiment for her homework.
If you would like to try the experiment at home, follow my daughter’s video above. What fruits will you try?
After reading GeekMom Melanie’s post about this morning’s lunar eclipse, I was motivated to get up early and rush out the door with my camera to take pictures. By the time I got to a local park near my house in Fuquay-Varina, NC, the eclipse had just started to cover the moon. I immediately set up my camera with tripod and started taking pictures while enjoying the show. I hope you enjoy this series of pictures.
