What We Do


Engaging Contests

Download our science activities to conduct in your homeschool and upload the results to compare your class’s scores to the scores of classes from all over the world.

Lesson Plans

No background in science?  No big deal. Our activities include basic supplemental science curriculum material designed by educational experts.

Emphasis on Team

Team scores are greatly affected by how well the team members work together, instilling in your homeschool students the value of teamwork.

Why We Are The Perfect STEM Solution For The Homeschool

  • No science background required!  (In fact, we throw in supplemental curriculum material for you to teach from!)
  • Extremely cheap materials, most of which can be found in the home.
  • Go at your own pace.  Do as many activities or as few as you like.
  • Expose your kids to STEM competition while keeping them in a familiar environment.
  • Built for the household on a budget, STEM Playground is low cost.
  • Through our post-activity discussion questions and writing activity, we use STEM to deliver English and math to the homeschooler.

Where We Are

STEM Playground began as a small pilot program for 10 schools but has grown to over 3000 schools worldwide!

How Our Competition Works

STEM Playground’s activities are designed to be completed by teams of two students and will have measurable results which you can compare with other classes globally, nationally, or even within your own community or school.

While you can compare results from just one activity, you can also compete in the cumulative League Challenge by completing all 12 designated League Challenge activities.

If you don’t want to compete but would rather just use our activities for your class’s enrichment, that’s fine too!
