CHES STEM Fair was a "pop"-ular event

With more than 30 experiments and 40 student participants, the Charlton Heights Elementary School STEM Fair brought in its fair share of spectators who viewed Science, Technology, Engineering and Math (STEM) projects and were able to get their hands (and feet) on a few demos. A popular demonstration--How to Stand on Balloons--demonstrated weight distribution. It included about 15 standard latex balloons inflated with air and placed between two pieces of plywood. Participants stood on the plywood to demonstrate that when force is applied evenly over large surfaces (in this case the sheet of plywood) weight is distributed throughout the surface. In fact, at one point fifth-grade teacher Mr. Deso, two students, and an adult participant all stood on the plywood for a total weight of 525 pounds and the balloons did NOT pop!

Other exciting experiements included everything from Make Your Own Slime and vortexes to How to Build Your Own Solar Charging Station and How Plants Reproduce. There were even live ducks and ducklings, and robotic demonstrations given by high school students and BH-BL High School robotics teacher Margaret Kelliher.
