STEM activities and STEAM for kids are great ways to develop skills kids can use throughout life. These STEAM activities are easy to do and low-prep!
STEM activities are just about our favorite thing to do around here. We love how you can incorporate nearly every subject into a STEM activity similar to homeschool unit studies.
Today, we’re sharing our favorite STEM and STEAM (STEAM is just STEM with an art element added) activities that require just about zero prep. While we love STEM activities that use weird supplies, sometimes we forget to go to the store.
So it’s nice to know that there are no-prep STEAM for kids activities out there. Here are some of our very favorites:
