Introduction
This lesson encourages learners to use their critical thinking skills to identify the causes of water shortages locally and internationally. Learners will discuss the topic in detail and produce a poster giving advice on saving water in the home or in the school.
Learning outcomes
Materials
- Board game– cut up so each learner has one board and each group two sets of 8 picture cards per group of 4 learners.
- Statements – 1 set cut up (more if you have a large class). Stick them around the room
- Materials for making a poster such as card, coloured pencils, scissors and magazines to cut up
- Worksheet
Save water
- Demonstrate the card game with 3 strong learners. The other learners surround the desk so they can see how the game is played
- Give each player a game board
- Elicit what is happening in each picture card. Support as needed. Then place the cards face down on the table
- The first player picks up a card and keeps it secret.
- The other players have to find out if it´s one of their pictures by asking a question such as
´Is she watering the garden?´ Prompt the learners to make the correct question.
Note: You may need to write some question examples on the board
- Players take turns to ask until the person holding the picture says ´yes´
- When the player with the picture card answers yes, the player who asked the right question wins the card and puts it on their board.
- That person takes the next picture and the others ask them the questions
- Explain the winner is the first to match all 4 pictures on their board. They should shout ´BINGO!´.
- Once you’ve demonstrated the game put learners into groups of 3 or 4 to play the game.
- Monitor and check groups are on task. Praise use of English
- Put learners into pairs. Reallocate the picture cards so that each pair has a set of 8 cards
- Ask learners to rank the 8 pictures according to which they think use the most water
- Point out the statements around the room. Tell learners there are 8 statements
- Ask one learner from each pair to be a reader, the other a writer
- The reader memorises each statement to tell the writer. The reader cannot write (except for differentiation reasons)
- After a few minutes ask the reader and writer to swop roles, if possible
- Once pairs have all of the statements ask them to check their ranking. If needed write the statements on the board.
Statements
-
- Washing the car uses an average of 1,892 litres.
- Having a bath uses an average of 189 litres.
- Watering the garden uses an average of 76 litres.
- Eating a burger uses an average of 57 litres.
- Washing clothes uses an average of 38 litres.
- Flushing the toilet uses an average of 11 litres per person per day.
- Having a shower uses an average of 8 litres per minute.
- It takes 3 litres of water to make 1 litre of bottled water.
- Ask learners if any of the statements surprised them
- Ask ‘What should we do to save water?’ as a follow up. Prompt them to use full sentences with ‘should’ in their responses.
Note: If you have a large class, make a few copies of each statement
Differentiation: If some learners find reading or writing difficult select the role that will be easier for them and pair them with a stronger learner. Or put them in a group of 3 so they have additional support.
- Tell learners that in the amount of clean water available for people to drink in many countries has reduced greatly. If possible, draw a graph on the board to demonstrate the point.
- Ask learners to guess why this has happened
-
Possible ideas
- Drought – not enough rainfall
- Warmer climate
- People wasting water
- More washing machines/ dishwashers
- Larger industries
- Explain to your students the importance of saving every drop of water. Some points to mention:
- less than 1% of the Earth´s water supply can be used by humans,
- cleaning water for households uses up lots of energy
- the more water there is being treated, the less effective the cleaning is (as water is wasted, the quality of water declines),
- water shortages can have severe impact on wildlife and plants in and around rivers, lakes etc.
- Ask the learners what they can do to help save water – write the ideas on the board. Again prompt them to use should
- Put learners into groups and ask them to come up with 10 ways to save water at home or in school
- Monitor and write any useful vocabulary on the board
- After 10 minutes give each group some materials to make a poster
- Groups put their posters on the wall.
- Give out the worksheet as revision
- An optional game with questions on water and water saving tips can be found here: https://www3.epa.gov/watersense/kids/games.html
