The energy is not really lost, it is just converted to a different form. Pupils learn about the conversion of energy in the fifth segment of an energy unit with six parts. Learners develop an understanding of the conservation of energy and the loss of energy in the form of heat, sound, or light.

Concepts

energy, energy conservation, energy conversion, energy transfer, energy transformation, the law of conservation of energy, electricity, technology resources
