1. Monday, March 14, 2016 Thermal Energy and Heat Changes of State

2. Solid Liquid Gas

3. Solid solidification Liquid Gas

4. Changes of State Solidification (freezing) – when a liquid turns into a solid (because the particles slow down and lose/release energy)

5. Solid solidification Liquid Gas

6. Solid solidificationfusion Liquid Gas

7. Fusion (melting) – when a solid turns into a liquid (because the particles gain energy and move faster)

8. Solid solidificationfusion Liquid Gas

9. Solid solidificationfusion Liquid condensation Gas

10. Condensation – when a gas turns into a liquid (because the particles slow down and lose/release energy)

11. Solid solidificationfusion Liquid condensation Gas

12. Solid solidificationfusion Liquid condensationevaporation Gas

13. Evaporation – when a liquid turns into a gas (because the particles gain energy and move faster) Evaporation

14. Solid solidificationfusion Liquid condensationevaporation Gas

15. Solid solidificationfusion sublimation Liquid condensationevaporation Gas

16. Solid solidificationfusionsublimation Liquid condensationevaporation Gas

17. Sublimation – when a gas turns into a solid or a solid turns into a gas without turning into a liquid.

18. Discuss changes the students have seen in their everyday lives – e.g. “sweat” on cold drinks, snow melting, opening the freezer door and seeing “steam”, “steam” from the river in the fall, etc.
