How hungry are your appliances?

 30 minutes  Activity

Look around your home, there are appliances everywhere! Which ones use a lot of energy and which ones are energy savers? What does “energy efficiency” mean and what’s so important about being energy efficient?

Black or white?

 70 minutes  Experiment

Have you noticed how most of your summer clothes are light coloured and your winter clothes are darker? It’s not just fashion, it’s science. Colour and light play an important part in transmitting heat or thermal energy.

Carbon dioxide in action

 30 minutes  Experiment

Carbon dioxide is vital to life on earth, but what is it and what affect does it have on energy?

Energy detectives

 30 minutes  Activity

Most of the things we buy from the shops have had a really long journey before getting to the shelf. And each step of that journey uses energy. We can call this embedded or hidden energy.

 

Energy investigations

 30 minutes  Activity

We use energy every day but a lot of the energy we use is electricity, gas and fuel (petrol); all of which are limited sources. We need to find ways to use less energy and also use a source that isn’t limited.

Heat on the move

 90 minutes  Experiment

Energy moves. Sometimes we want energy to move quickly, like when we use the stove to heat up our dinner. In this case, we need good conductors of heat energy. Sometimes we want energy to stay put, like when we use a heater to warm up our room. We want the heat to stay in our room, so we need insulators.

Appliance assessment

 30 minutes  Activity

Generally, the electricity that powers all our appliances is generated from fossil fuels. And fossil fuels are fast running out. Ideally we want an energy source that is plentiful and can be replenished or renewed.

Energy calculations

 30 minutes  Activity

We know energy comes from different sources like coal and gas.  But how do we measure each one? It helps to know how to measure energy so you can compare how much you use every day.

Energy investigations

 30 minutes  Activity

Once we look at or investigate our own actions, we can start to think about what we can do to improve our use of energy. How much energy does our family use? How many appliances do we have that use a lot of energy? What do we do that uses a lot of energy?

Finding hidden energy

 30 minutes  Activity

When we talk about hidden energy, we’re referring to all the energy used to get a product from the factory or farm to our shopping trolley. What are some of the hidden costs of energy and what can we do to minimise hidden energy?

Promoting energy efficiency

 60 minutes  Activity

Now that we know about energy efficiency, we can show off our knowledge and persuade others to get on board.

The cost of television

 60 minutes  Activity

We watch a lot of TV every day. In 2014, Australians watched an average of over 90 hours of television per month, or at least 2 hours every single day.[1] With so many Australians watching TV, what is the actual cost of using this appliance?

 

Black, white or silver?

 70 minutes  Activity

Heat travels from the Sun to the Earth through electromagnetic waves. Because these waves are different lengths, we refer to these waves collectively as the electromagnetic spectrum.

Energy poetry

 60 minutes  Activity

Using our knowledge of renewable energy, let’s create a cinquain poem. A Cinquain poem has specific syllables and word count and can also be called Didactic cinquain.

Energy smart classroom

 60 minutes  Activity

Natural light helps with our own health and a healthier use of electricity.

Solar pasteuriser

 30 minutes  Activity

Pasteurisation isn't just for milk. Pasteurisation is the process of heating a liquid or food to a high temperature to kill bacteria and make it safe to eat or drink. The sun can be used for the pasteurisation process.

Sunshine in my neighbourhood

 30 minutes  Activity

Australia is ‘a sunburnt country, a land of sweeping plains’; making it a great place to generate solar energy.

Water, gravity and Isaac Newton

 30 minutes  Activity

Kinetic energy is the energy of motion. Hydropower converts kinetic energy from falling water into electricity.
