By considering examples where energy is conserved, I can identify the energy source, how it is transferred and ways of reducing wasted energy. 

SCN 2-04a

Benchmarks:

·    Demonstrates understanding of the law of conservation of energy (energy can be converted from one form to another but cannot be created or destroyed).

·    Identifies the common types of energy (kinetic, potential, electrical, chemical, light, sound and heat) used in energy transfers and transformations that occur in everyday appliances.

·   Explains that when energy transfers and transformations take place, energy is converted into ‘useful’ and ‘wasted’ energy, for example a mechanical braking system transforms kinetic energy into heat energy which is dissipated to the atmosphere as ‘waste’ heat.
