Science is about questions, getting dirty, observing, discovering, and having more questions. For many of us taught in traditional schools, science “lab” was about following directions and if you didn’t get the correct result, you were wrong. That is a great way to kill anyone’s curiosity or love of true science. Don’t let that happen with your kids!
Your child’s education may include a fantastic science program or not, but you can always do fun things as a family. It’s spring (it may not feel like it, depending on where you live, but technically…) and that means planning a garden. I’m no green thumb. That’s my husband, but the kids and I are involved throughout the growing season.
This year, my son (15) decided on a science project that involved growing seeds. He wondered about chamomile tea and if it was good for plants. Some websites said yes, but were really vague. He decided to do his own study.
We went to the garden store and spent a minimal amount of money on basil seeds (because they can be transplanted in our garden or grown inside in pots afterwards. And I like basil!), potting soil, and a few containers.
Next he planted the seeds in three groups:
1. Potting soil that will have plain water every day.
2. Potting soil that will have brewed (and cooled) chamomile tea every day.
3. Potting soil mixed with chamomile that will have plain water every day.
Originally, he only had groups 2 and 3, which led to a discussion on why you want a “control” in your study.
It’s been a couple of weeks and they are just starting to sprout. Guess what he’s found out so far? Light is far more important than anything else he’s doing. The seedlings closest to his light source are doing the best. Does that mean his experiment isn’t good? Not at all! He’s learning that there may be other factors that affect his outcome. This will lead to a better experiment next time. And that’s real science learning.
For your own experiment, let your child look through your spice or tea cabinet and choose something they think will help or hurt plants. Let them plant some seeds and take care of them. Will they spill dirt, take up space in your house, and need reminding about watering? Probably. But science isn’t neat and helping them succeed is worth the inconvenience.
Remember: Success is simply completing the experiment, regardless of the outcome. Look at the results together and chat about what worked in their design and what would make a clearer result next time. You don’t have to be a scientist yourself to have a conversation about it—just be curious and observant.
Here is a lot of good information on what seeds need and how to plant them. And here’s a video on seed starting:
