Activity 1: Warm-up · 5 minutes
Warm-up: Water pollution brainstorm
a) Aims
Ss activate prior knowledge about water pollution and recall the topic vocabulary they will need for listening and writing.
b) Content
Ss look at the pictures or words on the board showing water pollution sources and answer the teacher's questions:
- What things can pollute a river or a stream?
- How can everyday waste reach a stream?
- What can we do to reduce pollution in our area?
Ss use the words: pollution, habitat, ecosystem, endangered, reduce, reuse.
c) Expected outcomes
A class list of 4–6 pollution sources and 3 actions to reduce them, for example: plastic bags, household rubbish, factory waste, sewage; reduce single-use plastic, reuse water bottles, do not throw rubbish into the stream. Ss can use the vocabulary correctly in full sentences, for example: 'Plastic bags can harm river life.'

Step 2: Task performance
T gives Ss 1 minute to think, then asks them to call out ideas. T writes the key words on the board.
Students
Ss work in pairs, discuss the pollution sources and the ways to reduce them. Possible answers: 'Rubbish from homes can reach a stream.' / 'We should reuse our water bottles.'
Teacher
Step 3: Report and discussion
T invites 2–3 pairs to share their ideas and corrects pronunciation of the key words (pollution, habitat, ecosystem).
Students
Representative pairs share their answers. Other Ss repeat the new words after T.
Teacher
Step 4: Conclusion and assessment
T praises the good ideas and introduces the lesson aim: 'Today you will learn a listening strategy and how to write a notice.'
