What Is STEM For Kids?

STEM sounds complicated, but it isn’t! Once you get how science, technology, engineering, and math (STEM) mingle, you can see how it applies to so many of the science and STEM activities you already love.

The best STEM activities encourage your kids to use at least 3 of the 4 pillars of the STEM acronym (science, technology, engineering, and math) to tackle their projects head-on, challenge what they know, and build character. The lessons STEM can teach our kids are priceless!

Have you played around with science with your kiddos? If you haven’t, you are in for a real treat. And if you have, you already know how much fun STEM activities are…

Unlock your kids’ curiosity, and spark their inner inventor! The world of science and STEM is AMAZING with these hands-on science experiments and STEM activities!

You don’t have to be a rocket scientist to share STEM with your kids. We have everything you need: simple-to-follow activities, low-prep ideas, easy-to-digest science information, and inexpensive supplies.
