Energy circus Specification references P 1.1.1 Energy stores and systems, P.1.2.1 Energy transfers in a system WS 1.2. Aims In this activity students will practise describing energy stores, energy transfers, and the processes by which energy transfers take place, as they are prompted by a variety of observations. High-attaining students will also describe factors affecting the capacity of energy stores. Learning objectives After completing the practical students should be able to: describe energy stores, and say when an energy store is increasing or decreasing describe energy transfers, and name processes which make energy transfers happen. Teacher notes Before doing the practical, students should be introduced to the concepts of energy stores, energy transfers, and some of the processes by which energy transfers happen. You should also check whether students remember, from their previous learning, any types of energy store such as kinetic, elastic, – and gravitational potential energy stores. The practical helps students to apply these ideas to a range of scenarios. The activity can be adapted according to the equipment available. Alternatives include: radio-controlled car; wind-up radio; solar-powered cart; MP3 player. Check beforehand that students can access the recommended website (which requires Java to run). Alternatively, you may instead download and save the simulation and then play it offline. Answers for method sheet Wooden block falling onto the floor Gravitational potential energy.
