We are studying electricity this week. Be sure that you understand what conductors and insulators are and how to build a simple circuit. You should be familiar with the concept of energy transformation and that electricity can be changed into many different forms of energy. For example, an LCD projector changes electricity into light, heat, mechanical and sound energy.
