Lesson 8Kb: Transferring energy Learning objectives Exemplar teaching activities Differentiation Resources Maths skills Practical skills Developing Recall that energy can be transferred by heating in conduction, radiation and convection. Recall examples of common thermal conductors and insulators. Identify the process(es) in which energy is transferred by heating in a given situation. Describe how energy is transferred in conduction, convection and radiation. Explain why particular materials are used for given purposes. Use the particle model of matter to explain energy transfers by conduction and convection. Securing Compare conduction in thermal conductors and thermal insulators. Explain the process(es) in which energy is transferred by heating in a given situation. Compare conduction, convection, radiation and evaporation as methods of heat energy transfer. Exceeding Explain the causes and effects of wind chill. Starter: Touching materials Provide students with a range of different materials, including metal objects and insulating materials, such as polystyrene foam. Ask them to touch each material and decide whether it feels warm or cold. Ask them to suggest why the materials feel different to the touch. Exploring: How fast does metal conduct heat? Students measure how fast heat travels along a metal rod, using a clamp and temperature sensors at equal intervals along it. Explaining: Convection in water Demonstrate a convection current in water using a potassium manganate(VII) crystal, a tube, a beaker of water and a Bunsen burner. Ask students to explain why some of the water turns purple and then why the purple water moves in the way it does. Plenary: Energy transfer demonstrations Show students two demonstrations (wood and metal, and a smoke box) and ask them to explain what is happening in each case, using words n/a Resources from 8Kb Exploring Science. Choosing and using a suitable level of accuracy for Students measure how fast heat travels along a metal rod, using a clamp and temperature sensors at equal intervals along it. Demonstrate a convection current in water using a potassium manganate(VII) crystal, a tube, a beaker of water and a Bunsen burner. Show students two demonstrations (wood and metal, and a smoke box) and ask them to explain what is happening in each case.
