20 Outdoor Fall Science Activities

20 Fall inspired science activities & experiments for preschoolers, kindergarten & elementary age kids!

I just LOVE Fall! 

Especially getting outside to enjoy the weather -- which always leads me to think about a few fun Fall themed science activities for kids.

With all the seasonal changes, science in the Fall can be so easy to come by and so colorful too -- kids will typically ask questions like "why do leaves change colors?", they look forward to making leaf rubbings and eagerly collect various nature items like pinecones & acorns for projects!

So today I hope to inspire you with some seasonal science -- experiments with leaves, apples, pumpkins and more Autumn favorites!

  20 Easy Fall science activities for preschoolers, kindergarten and elementary age kids

Fall Science Activities & Experiments

There's a LOT of science that happens outside during the Fall season:

  • leaves change colors
  • animals start hibernation, migration or adaptation behaviors
  • the night sky begins to shift - kids probably notice you can see the moon both at night & in the morning
  • the days become shorter and cooler
  • and trees begin to shed both their leaves and seeds

One of the best parts about exploring science in the Fall is being able to make a mess outside :) 

In addition to talking with kids about the seasonal changes they see around them, try a few of these hands-on activities and experiments that introduce your kids to different science concepts.  We've included affiliate links to some of our favorite items that are great for exploring Autumn science too!
