Parent Volunteers Needed!

All classes are taught by dedicated parent and community volunteers.  No prior teaching experience is necessary; just bring your love for science! Past hands-on, interactive classes have included: Aerodynamics, Tower and Bridge Building, Mystery Architecture, Matter Matters, Circuit City, Solar System, Disease Detectives, Sports Physiology and more! The D39 Educational Foundation will also offer all leaders one free class for one student in their household as a small token of appreciation for their time.
