Activity Introduction

Introduction: This Powerpoint is a great teaching tool to get students thinking about energy. They will learn some key ideas around the concept of energy and discover energy conservation tips. The Powerpoint can be used straight from the Cool Australia website or downloaded by clicking on the Powerpoint and using the SlideShare website. 

Key topics: Energy, electricity, kinetic energy, potential energy, renewable, non-renewable, conservation, energy saving tips.

Australian Curriculum content descriptions:

Year 7 Science:

  • Some of Earth’s resources are renewable, but others are non-renewable (ACSSU116)

Year 8 Science:

  • Energy appears in different forms including movement (kinetic energy), heat and potential energy, and causes change within systems (ACSSU155)
  • Scientific knowledge changes as new evidence becomes available, and some scientific discoveries have significantly changed people’s understanding of the world (ACSHE134)

Syllabus OutcomesSC4-15LW, SC4-12ES, SC4-10PW

Teacher content information: 

Energy is the ability to make changes or the capacity to do work. Energy appears in many different forms including kinetic (movement), potential (stored energy), gravitational, light, heat, chemical, elastic and electrical. The Sun is the source of all energy on Earth. The energy from the sun comes in the form of light and heat. Plants are able to convert the light energy from the sun into a form of energy they can use to grow, move, repair their cells and reproduce. The basic unit of energy is the joule. To give you an idea of this unit, one joule is enough energy to lift a 1 kg weight to a height of 10 cm. Power is the rate at which energy is used and the unit is a watt. 

Energy can change from one form to another: this process is called energy transformation. No energy transformation is 100% efficient and often heat energy is produced as the by-product. For example, a light globe transforms electrical energy into light energy (useful) and heat energy
