Energy detectives

efs instructions orange illustration


Embedded or hidden energy is the energy used to get a product from the farm or factory to supermarket shelves. It’s important to think about how much energy is used and ways we can reduce energy use by buying locally made goods.

efs ws discuss

Discuss the idea that there is hidden, or embedded, energy in every product we buy.

efs ws energy detectives 1

This hidden energy comes from making or growing the product and transporting it to supermarket shelves.

efs ws energy detectives 2

Using the Energy detectives worksheet and a map, list all the different parts of a journey for a pair of shoes made in London, United Kingdom, to your nearest shoe shop? What energy is used for each part of the journey ie.  Fuel, electricity etc


efs ws ask

Using their scientific understanding of energy, ask students to respond to a range of questions about hidden energy.

What can we do to make sure the food we eat and the goods we buy use less energy?
What are some of the things made in your own local area or state that you could buy? What can you make or grow yourself?

Extension: Food miles and fish fingers

‘Food miles’ is a term we can use to help describe how much embedded energy is in the food we eat. This interesting video shows the journey from fish eggs to fish fingers – and all the energy-intensive tasks in between.

A look at food miles and food waste


From the ocean to the plate, a lot of energy is used in transforming an ocean fish into a meal of fish fingers.


While you’re watching the video, write down all the different ways that energy is being used in the production of fish fingers.


Talk about ways that energy could have been saved in the production of this food, or any other foods.


Draw your breakfast and label where all the food on your plate comes from. Then list all the different ways each one got from the farm or factory to your plate.
