About this activity
A projector simulation: the camera dives from ice, liquid water and steam down to their particles. The class predicts what heating will do, watches the particles react, then explains the result with the particle theory.
What students learn
- Use the particle theory to describe how particles are arranged and move in a solid, a liquid and a gas
- Predict how heating changes the motion of particles and the spaces between them, then test the prediction
- Explain melting, boiling, expansion, gas pressure and condensation with the postulates of the particle theory
- Recognize a fair test: only the temperature changes, the sample and its container stay the same
