Activity Introduction

bulb6-heroQuick 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 switch to save logo

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.

Learning goals:

  • 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.

Overarching learning goal: By participating in this lesson students better understand how to use energy by collecting real world data about the appliances being used in their classroom. Students will also understand that replacing halogen downlights with LED downlights will have both environmental and economic benefits.

Teacher content information: Electrical energy is part of our everyday lives at home, at work and at school. Most of our energy is produced by burning fossil fuels and this has a range of environmental, social and economic impacts. One of the most significant impacts is the release of greenhouse gases. A solution is a transition to clean energy sources. Another solution is to think about our personal energy footprint and reduce the amount of energy we use.

In technical terms, energy is the ability to make changes or the capacity to do work. Energy appears in many different forms including kinetic, potential, gravitational, light, heat, chemical, e
