Quick summary: Students gather real world data to find out the number of different appliances in their classroom. Initially, student estimate the number of different appliances, then they count and calculate recording their data. They make recommendations as to how their classroom could use less electricity and link their findings to home-based energy saving programs, such as the Switch to Save program.
Activity developed in partnership with
This lesson has been designed to support Bendigo Bank’s Switch to Save program. This program helps reduce greenhouse gas emissions by switching halogen downlights for LED downlights for free. For every halogen globe switched Bendigo Bank donates $1 back to Victorian schools’ environmental projects.
- Students understand that we can better understand how to use energy by collecting data about the appliances being used.
- Students understand that replacing halogen downlights with LED downlights will have both environmental and economic benefits.
- Students take action to reduce their personal energy footprints at school and at home.
General capabilities: Numeracy, Critical and creative thinking.
Cross-curriculum priority: Sustainability OI.8.
