Students learn the main forms of energy (movement, heat, light, sound, electrical, chemical and stored energy) and trace how everyday devices such as fans, toasters and radios change energy from one form to another. They draw energy flow diagrams, tell useful energy from wasted energy, and explain why some devices are more efficient than others.

Start each energy flow diagram with the form of energy the device takes in.
Read the passage, then answer the questions.
Energy is what makes things happen. It comes in different forms. Kinetic energy is the energy of anything that moves. Thermal energy is heat. Light, sound and electrical energy are other forms we use every day.
Some energy is stored. Food, fuels and batteries store chemical energy. An object high up has gravitational energy, and a stretched spring or rubber band has elastic energy.
Energy is never used up or made from nothing. Instead, it is transformed (changed) from one form to another.
Circle the best answer or write your answer.
We can show an energy transformation with an energy flow diagram. For a toaster: electrical energy → heat energy (and a little light energy).
Many devices change energy more than once. A battery-powered lamp: chemical energy → electrical energy → light energy (and some heat).
Write True or False.
Useful energy is the form we want from a device, such as light from a lamp. Wasted energy is energy changed into forms we do not want, usually heat or sound, which spreads out into the surroundings.
An efficient device turns a large share of its energy into the useful form.
