STEM FOR KIDS

You can explore STEM with confidence when you dig into our list of the best ever STEM projects for kids. All of these STEM ideas will fit nicely into your lesson plans, whether you are engaging kids in learning in the classroom or at home.

If you have been looking to see how STEM and NGSS (Next Generation Science Standards) work together, check out our new series here.

Our STEM activities are designed with you, the parent or teacher, in mind. Easy to set up, quick to do, most activities will take only 15 to 30 minutes to complete and are heaps of fun! Plus, our supplies lists usually contain only free or cheap materials you can source from home.

WHAT IS A STEM PROJECT?

Let’s first start with STEM! STEM stands for science, technology, engineering, and math. So a good STEM project will intertwine two or more of these learning areas to complete the project. STEM projects often focus on solving a problem and can be based on real-world applications.

Almost every good science or engineering project is really a STEM activity because you have to pull from different resources to complete it. Results happen when many different factors fall into place.

Technology and math are also important to work into the framework of STEM whether it’s through research or measurements.

It’s important that kids can navigate the technology and engineering portions of STEM needed for a successful future. It’s good to remember there’s so much more to STEM than building expensive robots or being on screens for hours…
