4Energy-1
From MrReid.org Wiki
Contents
Outcomes
- Pupils can describe the different forms of energy.
- Pupils understand that energy can be transferred from one form to another.
- Pupils understand that energy is conserved.
Specification References
4.2 describe energy transfers involving the following forms of energy: thermal (heat), light, electrical, sound, kinetic, chemical, nuclear and potential (elastic and gravitational)
4.3 understand that energy is conserved
Starter
- Elicit types of energy that pupils already know.
Main Body of Lesson
- Issue pupils with definitions of forms of energy and run through each one individually.
- Differentiate between stored (potential) energy and "energy in use".
- Stored: nuclear potential, gravitational potential, chemical potential and elastic potential (a.k.a. stored mechanical energy).
- In use: kinetic, thermal, electrical, radiant (a.k.a. light) and sound.
- Introduce pupils to the concept of energy transfer.
- Include the concept of useful energy transfer with reference to filament lightbulbs.
- Pupils run through energy circus.
- Pupils run through energy transfers loop game.
A note on terminology
- There are a number of preferred terms here: please talk about "forms" of energy rather than "types" or "sorts" and please discourage the use of "heat energy" - heat is a verb, not a noun, the correct term is "thermal energy".
