Energy investigations

We use energy all day, every day. From when our alarm clocks wake us up in the morning, to when our parents drive us to school, to when we watch TV at the end of the day.

Set up time


What you need

Find the facts, Energy investigation, Energy snap worksheets


To encourage students to think about all the different ways we use energy, and to explore ways that we could save energy in our homes and lives.

Learning outcomes


Your students will discuss and debate various myths about energy, and learn the facts.


Your students will think of interesting questions and investigations about energy usage.


Your students will learn how to compare high energy activities with those that use less energy.


The energy we use every day is mostly made using fossil fuels. Typically, we use coal for electricity, oil for our cars and transport, and natural gas in our homes to heat up water. Because there’s only a certain amount of fossil fuels, we need to use less energy and find alternate sources.

Some of the information on the worksheet isn’t correct. Which ones are fact and which ones are just energy myths?

Energy investigation: encourage students to think up interesting questions about energy, and get peers to find answers.

Energy snap: match up high energy appliances with their low energy alternatives. Think of other possible pairs.

Conclusion: have a class discussion about how we can use our knowledge of energy to change our behaviour.

Draw three items in your home that use a lot of energy. Don’t forget things that are just outside your home, like cars and tools in the shed! What changes can you make to reduce the energy you use at home?
Walk around your school and find ways that your school can save energy. What uses up the most energy in your school? What is the most energy efficient item in your school?

Extension: A bike blender

We all like a fresh milkshake or smoothie! But a blender uses a lot of electricity. The good news? There’s an energy efficient alternative that uses your leg-power to charge up the blender. That’s right, it’s a bike blender!

That’s how many bikes are in Melbourne’s bike share program. Imagine if they all had blenders!


There are so many ways to generate energy. What are some of the ways we generate energy today?


As this video shows, a bike can be used to power lights, wash clothes, and grind up food. And the best part? It’s clean, green energy. What are some NEW ways to create energy?


How could you use a new way to create energy at home?


What appliance do you have at home that could be run by the Fender Bender?
