The higher the thermal conductivity of a material; the higher the rate of energy transfer by conduction across the material. 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 happen if insulation was not used in the home. model – it is possible using a beaker of hot water and a thermometer to find out how effective the insulation is in a 3D model that has been built. Investigate ways of reducing the wasted energy transfer in a rollercoaster – so that a marble dropped down a track will roll higher up the opposite side of the track. 4.1.2.2 Calculating efficiency. How to increase efficiency. Equations for the efficiency of an energy transfer should be known. The energy efficiency for any energy transfer can be calculated using the equation: Efficiency may also be calculated using the equation: Describe ways to increase the efficiency of an 1 Ask students to explore questions such as: Which type of power station is the most efficient? Which type of light bulb would cost the least amount of money to use? Research different types of power station to find out if combustion based power stations are less efficient that either nuclear or wind.
