Activity 1: Warm-up · 5 minutes
Energy sources brainstorm
a) Aims
Ss activate prior knowledge of energy sources and recall the topic of the unit before the listening.
b) Content
Ss look at the pictures of solar, wind power and coal, name each energy source and decide whether it is renewable or non-renewable. Key guiding question: 'Which energy sources can be renewed naturally, and which cannot?'
c) Expected outcomes
A quick class list: renewable energy: solar, wind power; non-renewable energy: coal. Ss state the difference in one sentence: renewable sources can be replaced naturally; non-renewable sources cannot be replaced in a short time.
d) Organisation

Students' activities
Teacher
Step 1: Task delivering
T shows the pictures and asks: 'What energy sources do you know? Which of them are renewable?'
Students
Ss look at the pictures and think about the question individually for 30 seconds.
Teacher
Step 2: Task performance
T monitors and encourages Ss to use the words they already know in English.
Students
Ss work in pairs, name the energy sources and sort them into two groups. Expected answers: solar, wind power (renewable); coal (non-renewable).
Teacher
Step 3: Report and discussion
T invites 2–3 pairs to report and asks: 'Why is coal non-renewable?'
Students
Ss report their groups. Expected answer: 'Coal takes millions of years to form, so we cannot replace it quickly.'
Teacher
Step 4: Conclusion and assessment
T confirms the answers and writes the title Energy sources on the board. T says: 'Today we will listen to a talk about saving energy and write about our family.'
Students
Ss copy the title and the key words into their notebooks.
