Activity Introduction

bulb4-heroQuick summary: Students observe and collect real world data to explain how energy is consumed in their classroom by looking at how, why and when appliances in their classroom are used. They make recommendations as to how their class 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 the relationship between energy use at school and a healthy environment.
  • Students recognise a range of strategies for saving energy at school.
  • 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 OI.8.

bulb8-heroTeacher preparation

Overarching learning goal: By participating in this lesson students will understand the relationship between energy use at school and a healthy environment. They will recognise a range of strategies for saving energy at school and at home, and will 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, potent

Student Worksheet

Thought starter: Imagine if we had no electricity - would your life be different?

In this activity you will be conducting an audit of the energy used in your classroom. You should use the table below (or create your own) to record:

  • Which lights and appliances are on or off.
  • How long they are used for.
  • Whether or not they have a standby function.

There are a number of different types of light that you might have in your classroom. Use the pictures below to distinguish between the lights.
