Ss work in pairs and use the words: appliance (thiết bị gia dụng), wireless (không dây), reduce (giảm bớt), reuse (tái sử dụng), human (con người), space station (trạm vũ trụ). Each pair writes three ideas in full sentences, for example: 'A robot can water the plants.'

Step 1: Task delivering
T writes the question 'What can a robot do at home?' on the board and shows the six vocabulary words. T explains the task: work in pairs, use at least four words, write three full sentences in 2 minutes.
Students
Ss read the question and the words, and listen to the instructions. Ss ask clarifying questions if needed.
Teacher
Step 2: Task performance
T walks around, checks pronunciation of the words and gives hints when Ss are stuck.
Students
Ss discuss in pairs and write three sentences in their notebooks. Possible answer: 'A robot can water the plants in the house.'
Teacher
Step 3: Report and discussion
T invites two or three pairs to read their sentences aloud and asks the class: 'Who used the word wireless? Is the sentence correct?'
Students
Pairs read their sentences. Other Ss listen, check the vocabulary used and give feedback. Possible answer: 'Yes, this is correct because wireless means without wires.'
Teacher
Step 4: Conclusion and assessment
T confirms the meanings of the six words, corrects any mistakes and introduces today's focus: will/might, the first conditional, articles, superlatives and stress.
Students
Ss copy the key vocabulary and the new lesson focus into their notebooks.
