AQA GCSE New Specification 8463 Unit 1.2 Energy: Conservation of Energy lesson 2 of 9

Objective:
To learn about energy changes in closed systems and that energy can not be created or destroyed on transferred.

Lesson Outcomes
Core Level 4
State that energy is conserved in any transfer.
State that energy is dissipated (is no longer useful) when it heats the environment.
Investigate the energy transfers in a pendulum and a bungee.

Challenge Level 6
Apply the law of conservation of energy in straightforward situations.
Describe the changes in energy stores explaining why energy ceases to be useful.
Describe the energy changes in a range of experiments and account for energy dissipation to the surroundings.

Aspire Level 8
Apply the law of conservation of energy to explain why forces cause heating effects.
Describe closed systems and the changes to energy stores within them using the principle of conservation energy.
Evaluate in detail experiments to investigate energy changes.
