Fall foliage sets the stage for some great interdisciplinary teaching. Plan a full day or sprinkle activities through the season. Grab your students’ attention with a colorful leaf chromatography experiment. Continue with some nonfiction reading. Create and analyze fall foliage maps. Explore personification in literature and film, then try some of your own. If you’re game, add a little math with factor trees. And what’s fall without a craft or two?
Science – Leaf Chromatography
This free experiment is sure to wow your students. First, cut up and mash red leaves and green leaves. (We use leaves from the same tree to design a fair test.) Then add isopropyl alcohol. Keep the ratio of leaves to alcohol high to make a more colorful concoction. Hang a strip of coffee filter from a pen or pencil so the filter dips into the mixture. You will begin to see some colors separating on the filter within an hour. Leave it overnight or longer for more magnificent results.
Time for Me to Leaf: Tree Chlorophyll Chromatography (8:44) complements this science activity well. The MIT students who created the video are entertaining in their leaf costumes, and they try the experiment using a slightly different process.
Fall Foliage Informational Texts & Videos
You can follow up the experiment with a video. For the scientific explanation, try one of these:
- Why Leaves Change Color (Untamed Science – 3:11)
- Why Do Leaves Change Color? (Super Scienced – 2:42)
Social Studies – Fall Foliage Map
When do leaves change color? Why do they change colors at different times? What factors determine when leaves turn color? Try this fall foliage map activity to find out!
Kids love these coloring sheets. They color states (or parts of states) to show when leaves change colors in each area of the country. Two levels, basic and advanced, allow you to differentiate for your group.
When students finish coloring, they compare their maps to landform or elevation maps. Analyzing patterns discloses four main factors in timing of fall foliage changes: latitude, elevation, proximity to water, and temperature (which is affected by the three other factors).
Fall Foliage Writing – Personification of a Tree
Trees are often personified in literature and film. Ask your students for examples. Afterward, read The Giving Tree by Shel Silverstein. As an alternative, watch this video of the apple trees from The Wizard of Oz.
Now ask kids to personify a tree of their own. After your students complete their masterpieces, let them illustrate with a little sponge art. (Or try this bundled Q-tip autumn tree art.)
Math – Factor Trees
Even math can tie into your fall foliage interdisciplinary teaching ideas. Try some prime factorization with factor trees.
