We love bringing our programs to this special retreat for very gifted kids and their families.  This was our fourth consecutive year with PGR, and we had a wonderful time facilitating our STEM labs, including our cave biology lab (with real live cultures), our waterproof flashlight lab, our epidemiology lab, and physics on the 12′ vertical caving tower.  We also had the opportunity to demonstrate conservation of mass using our carbide demo.
