This activity gets two teams to brainstorm all the ways we use electricity in our daily lives until they run out of ideas. Then, students work together to sort household items from highest to lowest energy consumption.

Participate as a class

A single screen and laptop is used for watching the video and answering questions together as a class.

Before you begin, make sure:

  • You’re connected to the internet

Getting started guide


What you'll need

  • Chalkboard and chalk (or smart board and markers)
  • “Our energy appetite” worksheets (print one per small group)
  • “Our energy appetite” slideshow

Brainstorming list-off

  1. Split the class into two teams. Each team will create a list on the board of ways we use electricity at home or at school. Members of each team take turns adding an item to their team’s list.
  2. The team that comes up with the most answers (without repeating any from the other team’s list), wins. For example, if Team A writes “microwave” on their list, Team B can’t use that one.
  3. The game ends when teams can’t think of any more items that use electricity.
  4. By the end, you should have two long lists. Have a look and discuss how important electricity is in our lives and encourage them to consider which are “needs” and which are “wants”.

Our energy appetites

  1. Divide the class into smaller groups and hand out the “Our energy appetite” worksheet to each group.
  2. Have students cut out the images on the worksheet and sort the pictures from those that use the most electricity to those that use the least electricity.
  3. To reveal the answers, pull up the “Our energy appetite” slideshow. Were they close? Any surprises?
