I’m bored be heard no more! If you are secretly wondering how in the world you are going to keep the kids busy (but not too busy) this summer, I’m here to help! Kids need free time to explore, but with 90 days of summer, 90-degree temps, you might want to check out some of our AWESOME science and STEM activities. Science for kids never sounded so good with these summer STEM activities.

SUMMER STEM ACTIVITIES WITH WEEKLY THEMES FOR KIDS

100 days of summer science and STEM to try with kids. Includes science experiments and STEM projects.

STEM FOR KIDS

STEM sounds complicated, but it isn’t! Once you get how science, technology, engineering, and math (STEM) mingle with each other, 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 science with your kids. We have everything you will need, with simple to follow activities, low prep ideas, easy to digest science information, and inexpensive supplies.
