Why Do Leaves Change Color? A Leaf Activity for Kids
Every autumn when the leaves start to fall from the trees, we admire the bright array of colors they display. We rake the leaves up, play in them, and even use them for crafts like this leaf symmetry activity. But do you and your child ever stop and wonder why the leaves change color and fall at this time of year?
Now is your chance to take the next step and discover the scientific side of fall. Just try this leaf activity for kids to find out why leaves change color. In the leaf experiment, you and your child will use chemistry to break leaves down and reveal their secrets.

All About Leaves
Do you have other questions about leaves? Here are some fun facts that might answer them.
Why do trees grow leaves?
Trees grow leaves to conduct photosynthesis. During photosynthesis, the cells in leaves turn sunlight into the sugars and starches trees need for food.1
Why are leaves green?
Chlorophyll is a pigment that gives leaves their green color. All trees have chlorophyll because they need it to soak in sunlight for photosynthesis.2
Why do leaves fall?
If leaves didn’t fall, they would freeze during the winter because they contain water.1
How do leaves fall?
To shed its leaves, a tree will form barriers of cells between its branches and the stems of the leaves. These barriers keep water and other nutrients from entering the leaves, so chlorophyll production stops.2 This process begins and causes the leaves to change color when the days become shorter. 3
