Look out any window in West Virginia right now and you'll see a science lesson happening in real time. In late September, the state's tourism department announced the first signs of 2026 fall color in the high country around Canaan Valley, Blackwater Falls, Dolly Sods and Spruce Knob, and promised weekly foliage updates as the color rolls down the mountains.
Here's the question that turns a leaf-peeping drive into a homeschool unit: where do the reds, oranges and yellows come from? Most of those colors were hiding inside the leaf all summer. Kids can prove it at the kitchen table this week.
And while you're out collecting leaves, take a second look at the apple trees. West Virginia has a famous apple story: the Golden Delicious was discovered in Clay County in 1912 and became the official state fruit in 1995. Orchards don't grow apples like that from seed, because apple seeds don't "come true." They copy the tree using pieces of the parent plant. That's a big idea your kids can test with their own hands.
What your kids will learn
Grades K–5
- Leaves hold more than one color; green chlorophyll covers up yellow and orange pigments
- Trees get ready for winter by shutting down their leaves
- Some plants can grow from a piece of a parent plant, not just from seeds
- How to spot nodes and buds on a twig, and how to record what they see with drawings
Grades 6–12
- Pigment separation (paper chromatography) and why chlorophyll breaks down in fall
- Sexual (seed) versus asexual (cutting) reproduction, and why orchards clone apple trees
- How plant hormones called auxins trigger new roots
- Designing an experiment, tracking conditions and writing a lab conclusion
This week's activity: Uncover the hidden colors in a leaf
All you need are a few leaves, coffee filters, small jars and rubbing alcohol. An adult should handle the alcohol, and keep it away from flames.
- Collect leaves. Pick a few green leaves and a few that are turning, from the same kind of tree if you can (maple works well). Label them "green" and "turning."
- Tear and mash. Tear each leaf group into tiny pieces and drop them into its own jar. An adult adds just enough rubbing alcohol to cover the pieces. Mash with a spoon for a minute.
- Wait. Cover the jars loosely and set them in a bowl of warm (not hot) tap water for 30–60 minutes, until the liquid takes on color.
- Add paper strips. Cut coffee filters into strips about 1 inch wide. Stand one strip in each jar so the bottom just touches the liquid. Tape the top to a pencil laid across the jar.
- Watch the colors climb. Over the next hour or two, bands of green, yellow and sometimes orange creep up the paper. Different pigments travel different distances.
- Record and compare. Older kids measure how far each band traveled. Younger kids draw what they see. Which leaf had more yellow showing? Why?
Bonus round: Bring home a short twig from any tree and have kids find the nodes, the bumps where leaves and buds grow. Those nodes are exactly where new roots can form on a cutting, which leads right into the next experiment.
Take it further: grow a new apple tree from a cutting
Our Plant Propagation Science Kit – Root an Apple Cutting turns the "how do orchards copy a tree?" question into a real experiment. Kids prepare a fresh apple cutting with rooting hormone, then observe and document whether and how new roots form over the following weeks.
- In the box: 1 fresh apple cutting (scion wood) with several growth nodes, a rooting hormone packet, a moisture wrap and printed rooting instructions
- Curriculum included: 4 lessons for K–5 or 5 lessons for 6–12 (you choose at checkout), emailed after purchase
- Worksheets included: a cutting diagram to label, a weekly observation log and a reflection sheet or lab report template
We'll be honest: rooting a fruit-tree cutting is a real experiment, and results vary with conditions. Figuring out why it worked (or didn't) is part of the lesson, and it's exactly the kind of thinking scientists do.
Join the growing community
Every kit purchase includes an invitation to Aardvark's Seed Planting For Little Hands, our private group for families using our kits. Kids can share photos of their cuttings, compare notes and ask questions alongside other young growers in West Virginia, Arkansas, Arizona and beyond. A Mountain State apple twig could be the most talked-about experiment in the group this month.
Ready to start?
Collect your leaves this week while the color is at its best, then keep the science going with a hands-on cloning experiment your kids can watch for weeks.
