Energy Transformations in Skate Park

This video lesson covers a mechanical energy lab using the PHET energy skate park simulation. Students learn to investigate energy transformations, identify kinetic and potential energy, and predict energy changes. The lab involves observing a virtual skater on a half-pipe, analyzing energy changes with and without friction, and collecting data on energy types. The lesson concludes with a summary of energy concepts and encourages students to ask questions for deeper understanding.
