Year 10 GCSE (Higher) ENERGY FOR THE HOME OCR Gateway Science Suite Lessons 5-6 (P1c) 1) Describe how energy is transferred by: Conduction, Convection, Radiation 2) Explain, in terms of domestic situations, how energy transfer can be reduced by: Conduction, Convection, Radiation 3) Explain how trapped air in foam prevents energy loss by convection.


(Can-Do Task P1c How Insulation Works Name: ENERGY FOR THE HOME Date: 3 points I can carry out an experiment to compare the performance of different insulating materials.  Method Set up apparatus as show in the diagram. Pour ml of hot water into each beaker. Take temperature readings every min for minutes. Record the data in the table below. Draw a temperature–time graph. Results table Time (min) (°C) (°C) (°C) (°C)

This results in the transmission of heat energy through the material.HEAT TRANSMITTEDPoor conductors: glass, plastics and iceHow Insulation Works17 May 2010James Ferguson Claydon High School
