STEM Playground’s Core Mission

STEM Playground prepares elementary students for team-based STEM competition through  activities designed to create excitement about STEM at an early age while assessing and developing the character traits required for effective collaboration.  Through our online virtual STEM tournament, teachers conduct simple, inexpensive science-based activities with their two-student teams, then upload their scores to compare with other teams and classes around the globe.
