The students at the Boys and Girls Club of St. Joseph County had a special afternoon on March 23 as six groups of students from Notre Dame engaged them in STEM activities for two hours. ND Energy scientists Justin Blake and Tom Burns created foam to demonstrate the breakdown of hydrogen peroxide into oxygen and water while releasing heat energy. In spite of the children’s pleas for an explosion, Justin and Tom taught them about safety in the lab by having them wear goggles.  Showing youthful enthusiasm, one participant covered her entire face with safety glasses. After the demonstration, some of the children’s energy was released by passing around a hand crank flashlight to experience mechanical energy being transformed into light. Thanks to Justin and Tom for their time and patience.
