This document outlines assessment objectives and criteria for evaluating student work on an energy audit activity. The activity requires students to: 1) conduct an energy audit of their home by surveying devices and their energy usage; 2) identify the five highest energy consuming devices; and 3) write a report making recommendations to reduce energy use and discussing environmental and financial impacts. Students will be evaluated on their scientific knowledge, problem solving, use of evidence, and communication skills.

- 3. ATL Skills: Information Literacy Skills – Process data and report results Creative Thinking Skills – Interpret data Introduction Have you ever been reminded by your parents to turn things off after you have used them at home? The energy we use every day has to be generated or extracted from energy sources in nature. In this activity, you will “audit” the energy sources used in your home and make recommendations about how to reduce energy usage in your home. Instruction • Carry out an energy audit of your home. Survey every room and write down all the devices or machines that use energy in some form (for example, electricity, gas, coal and so on). • Organize your survey in a table that clearly shows the number of such devices, and the energy source that each uses. • Research to find out how much power (in watts) each of the machines in your house uses. You may be able to find this out by looking at labels on the back of the devices. Now multiply the power of each machine by the number of such machines in the house. Include this value in your energy audit table. • Using your data, identify the five machines in your house that use the most energy. • Now write a report for your parents, explaining how you carried out your energy audit. Analyze and summarize your data and suggest how you could minimize the energy use of your house by minimizing the use of these five machines. • Discuss the impacts this might have on the environment and on your household finances.
