This lesson uses the an inquiry-based approach to learning modified from the BEETLES Learning Cycle to explore wind and wind energy. 

Students explore the relationship between potential and kinetic energy in roller coasters while competing to score the most points. The track is made of foam pipe insulation available at home improvement stores, and the riders are marbles and or steel bearings. Two versions of the activity are attached. The full activity  can take up to a week and includes greater detail, calculations of PE and KE and reflection questions. The inquiry only version is used as an introduction activity only and takes only two class periods.
