During a 2-day program at Creative Montessori School in Birmingham, AL, 1st – 8th grade students had a blast exploring CaveSim.  The older students participated in science experiments using working carbide lamps, as well as with a special high-pressure carbide lamp designed and built by CaveSim inventor Dave Jackson.  The students learned about conservation of matter, exothermic reactions, density, and measurement concepts like significant digits.  Students also learned physics concepts on the CaveSim vertical caving tower, and practiced teamwork and communication skills using the cave rescue stretcher.
