Why STEM Playground Works

STEM Playground is a non-profit public charity focused upon providing the lowest cost and most fun science, engineering, and mathematics enrichment available.
“Today’s student needs not only skills, but experience that will develop confidence. To be successful, a student must learn to believe in themself, believe that they can make a difference, and dare to dream of better outcomes. Hope is the foundation of all success.”
