Learning outcomes


Your students will conduct an audit of all the appliances that use energy in their homes. Which of these appliances could run on batteries? Are there any that could potentially run on renewable energy?


Your students will learn how to use the audit information to make informed decisions about energy usage.


Your students will use creative thinking based on research to provide an innovative solution.

Back in class, ask students to compare their audits in groups of 4 or 5. As a group, identify one appliance that uses the most energy.

efs ws discuss

As a group, invent and design a new way of generating energy for that appliance, like using bicycles energy, water, or human energy.

efs ws record

As a group, design a poster that shows how that appliance would work using your new energy source.

What else could you power using your new energy source?
Could you run this energy source to help power your school? Or an entire city?

Time required

Extension: Renewable energy

Increasingly, we’re relying on the energy of the sun and the wind. How do solar panels work? How do wind turbines work?

Carbon footprint explained


Other than solar and wind, what other renewable energy sources are already available to Australians?


Discuss the factors that stop people from using renewable energy.


Why don’t we use renewable energy all the time?


Why do you think renewable energy is called “Green energy”?
