1. Starter
Can you remember…
1. The forms/types of energy (list all 9)
2. The law of conservation of energy?

2. Kinetic Theory and Heat
(Part 1)
Atoms and Heat
Lesson 5

3. Learning Intentions
Use kinetic theory to explain the effect of
heat energy on matter

4. Expansion and contraction
Describe/Draw the ball and ring
experiment
Explain the effects in terms of movement
of metal atoms. Use diagrams.
Give an example of when expansion and
contraction of materials is important.

5. Conduction
Explain how heat energy passes through a
solid. Use diagrams and kinetic theory.
Explain why



gases and liquids are poor conductors or
Solids do not convect heat or
Why metals are better conductors than nonmetals

6. Temperature
Describe the difference between
temperature and heat.
energy movement particles
joules Celsius
Explain why sparks from an indoor
firework (sparkler) do not burn your hand
even thought hey are at hundreds of
degrees Celsius.

7. Compression and the gas laws
Why does the outside
of the shuttle become
incredibly hot during
re-entry?
What happens if close
the hole of a bike
pump with your finger
and pump it?
Use particle/kinetic theory to explain
either of these
