Autumn brings lots of inspiration for indoor and outdoor science experiments and activities. Leaves start to change colour and fall, conkers, helicopters, and other seeds drop to the floor, and the air becomes cool and crisp.
It’s the perfect time of year to learn about seed dispersion, different types of trees and why leaves change colour.
I’ve pulled together my favourite autumn science activities into one handy post to make fall science activities easier than ever!
1. Go on an autumn treasure hunt.
2. Try a simple STEM Challenge
3. Make an exploding seed pod.
4. Design a sticky seed pod.
5. Learn about different methods of seed dispersal.
6. Make flying helicopters.
