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?
Thanks to this post for the inspiration.
Excellent for those who love inquiry! Please continue to share ideas and explorations.
