We can all do our bit! Introduce them to the topic with this match-up activity. Then, get them to tick the ones they already do. You could ask them to use 'always/sometimes/usually/never'. Discuss the reasons for these actions. Which ones are easy? e.g. turning lights out. Which are more difficult? e.g. planting trees/persuading parents to leave the car at home etc... Finally, put them in a 'pyramid of importance'. Thanks to jecika for the great template.
