Hook: provide students with video clips of heli-skiing start with helicopter ride to the top of the mountain. ask students what kind of energies does involve in this activity?
Action: provide students with real world problem asking to calculate the potential energy?. Provide students with power point, and project that on the wall : ask key questions , refer to lesson hook activity , what is the gravitation potential energy? What is the potential energy? Name other potential energies? Create questions in order to help student relate the work, energy potential energy and gravitational energy. Refer to the real world problem and ask students to solve the question in group of 4.
Debrief: Use the concept map and provide students with real world problem. Student work individually and hand their work at the end of the class as exit card.
