Why Do Leaves Change Color?

[15 Minutes]

Try this scientific experiment to help your child explore why leaves change color.

You'll need:

• green leaves • rubbing alcohol (ADULT USE ONLY) • covered containers (some clear and some opaque)

What to do:

1. Invite your child to place some leaves in a clear glass container. Encourage her to add a few drops of water and then seal the container.
2. Invite her to place similar leaves into another clear glass container and seal it. Do not add any water to this container.
3. Help her to repeat steps #2 and #3, but this time use opaque containers instead of clear ones.
4. Place all of the containers on a window ledge where they will receive bright sunlight.
5. Each day, compare the changes in the colors of the leaves. Help her to think about "why" the changes are occurring. (For example: lack of light, lack of water.)

Let's Talk: Ideas to Explore Together.

• Why did you think leaves changed color before we did the experiment? Have you changed your mind?
• What is your favorite leaf color?
