Why do leaves change colors in the fall?
Curious about why leaves change colors in the fall? We have a great hands-on and easy chromatography science activity for you to explore this question.
Watch the video from WWLP News Channel 22’s Mass Appeal below.
- Rubbing alcohol
- Paper towels or coffee filters cut into strips
- Colorful fall leaves (but green leaves do cool things, too!)
- Immersion blender or mortar and pestle
- Glass bowl, cup, or mason jar
- Tear up leaves in tiny pieces. Remove the stems.
- Place leaves in a glass bowl or jar with a rim large enough to place an immersion blender in.
- Cover the leaves with rubbing alcohol.
- Blend (this was messy but fun for us!).
- Place the paper towel in the leafy liquid, folding the rim over the edge to hang it without it dropping in.
- Leave for 12-24 hours.
- Take the paper towel strips out. Drip dry them.
- What do you notice? What do you wonder? How might you find out more?
