Down in Mason County, on the grounds of the former Clements State Tree Nursery, stands a small grove of American chestnut trees that most West Virginians have never heard of. According to West Virginia Public Broadcasting, it is the only known sexually mature American chestnut orchard in the state, meaning the trees are old enough to bear nuts every year. Some stand about 60 feet tall.
That matters because chestnut blight wiped out roughly four billion American chestnuts over about 50 years. The West Virginia chapter of The American Chestnut Foundation collected about 900 nuts from this orchard this year, and those nuts are the main source of the seedlings the chapter shares for planting and research. Now a planned data center campus on the site has put the grove in the news, with a relocation plan proposed for winter 2027 and the story still unfolding. Inside Appalachia returned to it on November 6.
Whatever happens next, this story hands your homeschool a big science question kids can actually hold in their hands: why does a single seed carry so much of a plant's future?
What your kids will learn
Every seed is a tiny package of genetic instructions plus a packed lunch for the baby plant inside. When growers save seeds from plants that grow well, they pass those traits to the next generation. That is exactly what chestnut volunteers are doing, and it is what Appalachian families have done for generations with heirloom beans, corn and tomatoes.
Grades K–5
- Compare seeds by size, shape and color, and sort them into groups
- Learn the plant life cycle: seed, sprout, plant, flower, fruit, and back to seed
- See that different seeds sprout at different speeds
- Practice observing, measuring with a ruler and recording what they see
Grades 6–12
- Explain open pollination and why heirloom seeds grow "true" to their parent plant
- Connect seed saving to heredity and genetic diversity
- Design a germination trial with controlled variables
- Calculate germination rates and compare them across varieties
This week's activity: the Seed Detective sort and sprout test
You can do this one with seeds already in your kitchen. It takes about 30 minutes to set up, then a few minutes a day for a week.
- Gather your suspects. Collect four kinds of seeds: dry beans from the pantry, popcorn kernels, cleaned and dried pumpkin seeds (left over from a carving pumpkin works well), and seeds from a bell pepper. An adult should do any cutting.
- Sort and describe. Put each kind in its own cup of a muffin tin. Have kids describe color, shape and texture, and measure one of each with a ruler. Younger kids can draw them; older kids can build a comparison table.
- Make a prediction. Which seed will sprout first? Which might not sprout at all? Write the guesses down before you start.
- Set up the test. Place 10 seeds of each kind on a damp (not dripping) paper towel, fold it over and slide it into a labeled zip-top bag. Keep the bags somewhere warm, like the top of the fridge.
- Check daily. Count how many seeds have a root poking out and record the number for each bag. Keep the towels damp.
- Do the math. After 7 days, divide sprouted seeds by 10 and multiply by 100 to get a germination rate for each kind. Compare the results to your predictions.
- Talk it over. Why might some seeds fail? (Roasted or very old seeds often won't sprout.) For older kids: if you planted a seed from a hybrid pumpkin, would the new plant look like its parent? Heirloom seeds are the ones that reliably do.
These seeds are for science only, so toss them in the compost when you're done rather than eating them.
Want to take it further? Our Heirloom Vegetable Seed Science Collection gives you 30 individually packaged heirloom vegetable varieties, about 5,000 non-GMO, open-pollinated seeds in all, from Blue Lake Bush Beans and Bantam Sweet Corn to Sugar Pie Pumpkins and Roma Tomatoes. It also includes germination supplies and printed instructions, plus grade-level curriculum and worksheets emailed after purchase: five lessons for K–5 and six for grades 6–12, ending with seed saving and genetic diversity. The worksheets include a seed comparison and sorting sheet, a germination trial data chart, and a life cycle diagram (K–5) or lab report template (6–12). The experiment above becomes a full plant science unit, and you'll have seeds left over for a spring garden.
Join the growing community
Every kit purchase comes with an invitation to Aardvark's Seed Planting For Little Hands, our private group for families using our kits. Kids post their sprout counts and seed-sorting photos, ask questions when an experiment surprises them, and cheer each other on. You'll find young growers from the hollows of West Virginia alongside families in Arkansas and Arizona, all learning the same science in very different climates. After your order, just request to join and we'll add you.
Start your family's seed story
The chestnut volunteers in Mason County are proof that a handful of seeds can carry a whole species forward. Your kids can start their own seed story this week, right at the kitchen table.
