Free and Low-Cost Botany and Environmental Science Learning Resources for Kids, Tested by a Homeschool Mom
Last month I found my 10-year-old, Jesse, cross-legged on our front lawn at 7 a.m. holding three dandelions like they were rare gemstones. He’d woken up early to check if the flowers he’d marked the night before had really closed up like he guessed they would, and he was already bouncing with questions that my decades-old high school bio memory couldn’t answer. Why do dandelions close? Do other plants sleep? Can weeds be good for bees? I’d promised him we’d explore plants and nature deeper this spring, but all I could find when I searched online were overpriced activity kits for toddlers or dense college textbooks that made my eyes glaze over. I knew I wasn’t going to hold his attention with worksheets, so I started reaching out to other parents and teacher friends to find something that actually fit.
Over the last four weeks, we’ve tested close to a dozen different resources, and most of the ones that stuck are either free or under $10. The one that’s gotten the most use from Jesse is iNaturalist, a free app that lets you snap a photo of a plant to identify it. Two weeks ago we went on a hike at our local county park, and Jesse found a fuzzy vine with weird three-lobed leaves he couldn’t place. He snapped a photo, and the app ID’d it as poison ivy in 10 seconds, then added a little fact that it’s a primary food source for the caterpillars of royal moths. That blew his mind, because he’d only ever heard it called a nuisance. Now he logs every new plant he finds in our yard, and he joined a free kid’s observation challenge for urban areas where he compares finds with other kids to spot the most native species. The best part is, the observations he logs get used by real scientists for conservation research, so he gets that he’s not just playing a game—he’s contributing something.
Most people I talk to don’t know their local county extension office has free educational resources for kids, but ours has been a gold mine. Our extension office runs a program with master gardeners who lead free 1-hour walks at the community garden every Saturday. We went on our first walk two weeks ago, and the leading gardener let Jesse pull up a full grown carrot from the test plot to see how the taproot grows, then answered all 12 of his questions about why our backyard tomatoes never produce much fruit. He left with a $5 packet of native wildflower seeds from their free seed library, and we planted them in a window box by our front door last weekend. Most offices also host low-cost workshops on everything from composting to native bee conservation, so there’s something for every age level.
I did splurge on one highly-rated $80 botany kit I saw all over Instagram, just to test it. It came with a small microscope, pre-made plant slides, and a set of activity cards. When it arrived, half the slides were already dried out and crumbling, and the instructions were written for adults, so Jesse got bored 15 minutes in. We ended up dumping out the pre-made slides and making our own out of moss, dandelion petals, and pine needles we collected in the yard, which was way more interesting. That experience reminded me that expensive doesn’t equal better, and most of the best activities don’t need any special gear.
Project Learning Tree is another resource that’s worked really well for us. It’s free for K-12 teachers to download the full activity guide, and parents can get a digital copy for under $10. It’s full of short, low-prep activities that tie into real-world environmental science. We did the shade mapping activity last week: all you need is paper, a pencil, and a patch of yard. Jesse drew a map of our vegetable bed, then came outside every two hours to mark where the shade fell. By the end of the day, he figured out on his own that our hostas grow way better than our roses because the roses get full afternoon sun all summer, which is too hot for them. It took less than an hour total, and he walked away with a concrete understanding of how environment affects plant growth that no textbook could have given him.
Our local library has also come through with way more than I expected. I put a hold on Braiding Sweetgrass for Young Adults, and Jesse has been reading a few pages every night before bed. He keeps stopping me to read out loud passages about how strawberries spread through shared roots, or how native communities have cared for wild blueberry patches for hundreds of years. It’s equal parts botany and environmental storytelling, and it’s sparked more questions than any activity I’ve planned. If your library doesn’t have a copy, interlibrary loan is almost always free, so you don’t have to buy it. For quick video bits, the BBC Earth Kids YouTube channel has 5-minute clips on weird plant behaviors from Venus flytraps to giant sequoias that Jesse watches after he finds a new species, and it’s way less rambling than random search results.
Right now, Jesse’s current project is counting how many different pollinators visit our wildflower window box every week. He logs them on iNaturalist, and every Sunday he adds up the numbers to see if more bees come when the clover blooms. We still don’t have all the answers, and half the time I’m learning right along with him. Last night he asked me if plants can feel pain, and I told him we’d look it up this weekend with our resources. I don’t mind not having all the answers. The point isn’t to turn him into a botanist by 11, it’s just to keep that curiosity he had sitting on the lawn at 7 a.m. alive. So far, these resources have done that, without breaking the bank or taking over my whole schedule. Next month we’re trying the extension office’s free canning workshop for homegrown vegetables, so we’ll see how that goes.
