Exploring Why Leaves Are Green: A Classroom Experiment

In this engaging experiment designed for 2nd graders, students explore the reason behind the green color of leaves. Using green leaves and a jar of alcohol, they immerse the leaves in the alcohol and observe changes over a few days. Upon returning, students notice the leaves have turned yellow and the alcohol has taken on a green hue. This visual transformation demonstrates the removal of chlorophyll, the pigment responsible for the green color. This hands-on activity reinforces concepts of plant biology and encourages inquiry-based learning.
