Lesson Planning

Teaching

• Understand, through practical tasks, that materials change state when they are heated or cooled and describe this process using scientific language.

Activities

1. Use role-play as a model of how a substance can change from one state to another.
2. Learn to accurately use a thermometer.
3. Use scientific language to describe to another what happens to the particles when a substance changes state.
4. Make careful observations over time.
5. Use a data logger to record temperature over time and interpret the results.
6. Understand that liquids have a solidifying point (to become solid) and a boiling point (to change to gas).

Investigation - observing over time/exploring
Understand the behaviour of particles in the different states and use a thermometer to observe temperature changes of water.

Vocabulary
Solidifying, freezing, melting, condensing, evaporating, particles, thermometer, temperature, Celsius, Fahrenheit, degrees
