The small girl favicon

STEM Playground is a non-profit public charity focused upon providing the lowest cost and most fun science, engineering, and mathematics enrichment available.


“Students need not only knowledge, but experience that will develop confidence.  To be successful, a student must learn to believe in their ability to accomplish tasks, believe that they can make a difference, and dare to dream of better outcomes.   Hope is the foundation of all success.”  

Al Causey  2021
