1. Convection Objectives What are connection and conduction? Where can convection take place? Why does convection occur? Give examples of where convection occurs Describe particle movement in convection Explain why this does not occur in solids Explain why convection occurs in terms of particle movement, expansion and density

2. Predict what would happen to the ice if the boiling tube was made of metal, explaining why Explanation of your observations mentioning particles and including correct KW Description of your observations including use of KW Simple statement about what you saw No explanation for your observation

3. Thermal transfer in a fluid How does the heat transfer through the pan? What happens to the particles when they are heated and what does this cause? What causes the particles to rise?

4. Discussing your observations Give examples of where convection occurs Describe particle movement in convection Explain why this does not occur in solids Explain why convection occurs in terms of particle movement, expansion and density Explain why the water boiled but the ice did not melt How well do you understand?

5. Practical investigation
