lubrication – work done against the frictional forces acting on an object causes a rise in the temperature of the object and dissipates useful energy. the use of thermal insulation – the higher the thermal conductivity of a material the higher the rate of energy transfer by conduction across the material. on the rate of cooling of a building, of the thickness and thermal conductivity of its walls (qualitative only). the effectiveness of loft insulation, double glazing and cavity wall insulation. The evaluation could be based on cost, U-value, thermal conductivity, payback time or lifetime of the insulation fitted. Communication for audience and purpose: Design a poster to illustrate the reasons why insulating the home is beneficial for both the homeowner and the environment. Select specific examples and suggest what could happen if insulation was not used in the home. WS 1.4 Explain technological applications of science. opposite side of the track. Working critically with primary and secondary evidence: What is the best type of insulation to use in the home? Plan and carry out an investigation to find out which type of insulation will reduce heat loss the most. Investigate how the thickness of the insulating material used affects heat loss. Obtaining and presenting primary evidence: Design a building that will have very low heating bills. This can be a 2D or 3D model – it is possible using a beaker of hot water and buildings and insulation. Good examples include: YouTube: YouTube: Energy changes that take place in a rollercoaster:
