Quick summary: In this lesson students complete a whole school lighting audit with the aim of delamping classrooms. Students use a lux meter to identify over-lit areas of the school and also manually count the types of lights used. Using their real world data, students make key recommendations on how energy use could be reduced at their school. They then link their findings to home-based projects that reduce energy usage such as the Switch to Save program.
- Students recognise the relationship between energy use and greenhouse gas emissions.
- Students recognise where energy consumption can be reduced at their school and home.
- Students understand that replacing halogen downlights with LED downlights will have both environmental and economic benefits.
General capabilities: Numeracy, Critical and creative thinking.
Cross-curriculum priority: Sustainability O1.6.
