Objective
By the end of this 5-day lesson plan, the student will be able to understand why leaves change color in the fall and appreciate the beauty of nature.
Materials and Prep
Materials needed: leaves from different trees, magnifying glass, paper, crayons, watercolors
No prior knowledge needed, just curiosity and enthusiasm!
Activities
1. Leaf Hunt: Go on a nature walk and collect leaves from different trees.
2. Leaf Observation: Use a magnifying glass to observe the details of the leaves and draw them on paper.
3. Leaf Color Experiment: Paint the collected leaves with watercolors and observe how the colors mix and change.
Talking Points
- Leaves are like the plant's food factories. They use sunlight to make food for the tree.
- When the days get shorter and cooler in the fall, trees stop making food. The green chlorophyll in the leaves breaks down, showing other colors that were there all along.
- Red leaves have a pigment called anthocyanin, which gives them their vibrant color.
- Yellow and orange leaves have carotenoids, which are like the colors in carrots and pumpkins.
- Leaves fall off the trees in the fall so the tree can save energy and survive the cold winter. But don't worry, new leaves will grow in the spring!
