2 Working with the WordCloud, using lexical material from the previous video

3  Write on the board ‘If we ..., our homes would be more friendly to the environment’.

• Elicit possible answers for the first gap (e.g. If we unplugged devices when we aren’t using them /

If we used less electricity, etc.).

• Tell students that they will have to spot energy  waste sources in their classmates’ pictures (the

ones they have brought from their homes) and that they will give them advice.

4 Divide students into groups of four and explain that they will be discussing how they could improve houses and design appliances so as to minimise energy waste.

Home task

Tell your students to make use of the outside area of the school and create an energy-related ‘treasure hunt’ to spark students’ curiosity. You should simply use sticky notes on light switches or lamps/desktops available in the places students will walk through before coming to your class. Write questions on them such as ‘Did you remember to switch me off today?’, ‘How many hours am I plugged in at home?’, etc. The questions can vary depending on your students’ level.
