Welcome to our list of amazing outdoor STEM activities to keep your kids busy outside! Get kids outdoors to enjoy the natural world while developing problem-solving, creativity, observation, engineering skills, and more. We love easy and doable STEM projects for kids!

What Is Outdoor STEM?
These outdoor STEM activities can be used for home, school, or camp. Get kids outside and get kids interested in STEM! Take STEM outdoors, on the road, camping, or to the beach, wherever you go, but take it outside this year!
So you might ask, what does STEM stand for? STEM stands for science, technology, engineering, and math. Additionally, you might hear about STEAM, which includes an “A” for art!
We love STEM for kids because of its value and importance for the future. The world needs critical thinkers, doers, and problem solvers. STEM activities help kids better understand science, adapt to the latest technology, and engineer new solutions to solve problems of all sizes. Try our Real World STEM challenge!
Outdoor STEM is one of the best ways to get kids involved and keep them engaged. Below you will find nature STEM activities, outdoor science activities, and ideas for STEM camping activities. We even include some cool outdoor science experiments!
