Why Do Leaves Change Color? Autumn Leaves Fall STEM Activity

Integrate STEM in your classroom this Autumn!

In this STEM project, students complete a leaf chromatography lab in order to find out why leaves change colors. Aligns with Life Science NGSS (K-LS1-1, 3-LS1-1, and 4-LS1-1).

Students read about chlorophyll and the important role it plays in keeping plants alive, as well as how chlorophyll gives leaves their green color.

Students collect green leaves and make predictions about what color their leaves will turn. Students test their predictions and reflect on their results.
