Fun Fall STEM Activities for Kids of All Ages


Fall offers some of the most beautiful changes in nature and engaging learning opportunities for children. From leaves changing color to decomposing pumpkins and apples, the possibilities are endless for hands-on, fall themed activities for kids of all ages. This collection of 39 Fun Fall STEM Activities for kids will give you lots of ideas to try with your children at home, for parties or in the classroom.

If you haven’t heard of STEM activities before, they are activities, challenges and experiments that focus on Science, Technology, Engineering and/or Math. The more of these subject areas that you can combine into the activity, the better.

STEM activities are typically hands-on, low prep, and open ended. They focus on skills and subject areas that are growing in focus and importance in many schools and careers.

As a teacher, I can’t emphasize enough how beneficial STEM activities are. I have done STEM activities with children in preschool and into the intermediate grades. Children develop strong problem solving and team work skills as well as an incredible growth mindset from STEM activities.

Take a look through this collection of Fall STEM activities below to give you inspiration to bring to your own children or students. Choose activities that use materials that you already have on hand, or can easily access. Keep it simple and fun!

Once you’ve tried these STEM activities for fall, check out these 39 Halloween STEM activities kids will love, or 45+ STEM challenges for anytime of year!
