What you'll need

  • "Counting every drop" slideshow
  • "What's your water footprint" worksheet
  • Poster paper and art supplies

  1. Have students to pair up and challenge them to think of 10 ways they use water in their daily lives. 
  2. Using the "Counting every drop" slideshow, present slides 1 to 8 and have students guess how much water they use in a typical day.
  3. Have students fill in the "What's your water footprint" worksheet to calculate their total daily water use.
  4. As a class, have students compare their total water use with each other and with the Canadian national average (335 litres per day).
    • Why might their water usage be more or less than the Canadian average?
    • Are there other common water uses that weren’t mentioned?
  5. Present slides 9 to 13 and have students consider how the food we eat and the things we buy use a significant amount of water too.
    • Ask if they know how water is used to make electricity in B.C. (see Teaching notes).
  6. Continue on with slides 14 to 19, explaining that our "water footprint" includes all uses of water.
  7. Play the "Honouring water" video as an example of how the Leq'a:mel Nation in British Columbia honours water. Ask students to share why they think it’s important to reduce their water footprint.
  8. In small groups, have them brainstorm 10 ways to use less water and get creative by making a high impact poster that illustrates one of their ideas.
  9. Display the posters and have students check out each other’s ideas.

Teaching Notes

BC Hydro’s environmental responsibility

BC Hydro uses the power of falling water to create clean, reliable electricity. BC Hydro has become a leading sustainable energy company by producing and delivering electricity, in environmentally and socially responsible ways.

Young people can take action

Young people can act at school, in their community and at home to protect and care for water. We can empower them with a deeper understanding of how essential water is to life and encourage them to share this message to respect, protect and honour water.
