Set the iron to a hot setting. Cover the layers of wax paper with a couple sheets of newspaper and iron them. Students can observe the effects of light on the color of leaves. When leaves on a tree are still green, invite each student to cover part of a leaf with aluminum foil. Use masking tape to tape the foil to the leaf.
Students can sign their name on the masking tape.
Wait until the leaves on the tree change color. Let students work in teams to take a census of the trees in your school yard, an area of a nearby park, or another defined area. Students can use the survey data to create bar graphs that show the numbers of trees of different species. Invite students to unscramble some fall-related words. Choose appropriate words for your grade level.
