CAER reseachers Andy Placido and Stephaine Kesner recently spent time at the Deep Springs Elementary school to bring one of the CAER 101 modules - Using Motors to Make Electricity -  to the students during their review day prior to testing.  Demonstration of mini-wind turbine was used to show when blades spin, an LED bulb is lit.  Changing speeds of the fan at a set distance shows how this can change energy production.
