If heat causes particles to move around more, spread apart, and take up more space, then an object that is heated must expand (get bigger) and objects being cooled must contract (get smaller)!
The BALL and RING Demo:
Make a prediction what will happen during the demonstration. Record this on lined paper.
Watch the demonstration. Record what happens in 3 or 4 steps.
Explain what happened and why using the Particle Theory.
Level 3 responses will include: Particle Theory vocabulary, as well as the word, "expand" and "contract"
Level 4 responses will include the above, plus a real life example of how matter expands and contracts.
To be collected next class.
