Activity 1: Warm-up · 10 minutes
Brainstorming a Go Green Event
a) Aims
Ss activate prior knowledge about environmental problems at school and recall the key vocabulary of the unit (carbon footprint, reusable, household appliance, reduce, recycle, litter).
b) Content
Ss work in pairs to answer the question: “What can our school do to reduce litter and waste in one day?” Ss write at least three ideas and use at least three words from the vocabulary list. T shows the six key words on the board and models the pronunciation of each word.
c) Expected outcomes
Each pair writes a list of at least three ideas, for example:
- Bring a reusable bottle to reduce disposable cups.
- Reuse one-side printed paper before recycling it.
- Pick up litter in the school courtyard during break time.
Each pair uses at least three key words correctly in their list.

Teacher
Step 1: Task delivering
T shows the question on the board and says: “Today we will plan a Go Green event. First, let's brainstorm.” T writes the six key words on the board and reads them aloud for Ss to repeat.
Students
Ss listen, repeat the key words chorally and read the question silently.
Teacher
Step 2: Task performance
T asks Ss to work in pairs for 4 minutes and monitors. T prompts: “What is a practical way to reduce waste?”
Students
Ss discuss in pairs and write their ideas in their notebooks. Possible answers: “We can bring reusable bottles.” “We can recycle paper.” “We can reduce litter in the courtyard.”
Teacher
Step 3: Report and discussion
T calls on three pairs to share their ideas and asks: “Which idea reduces the carbon footprint most?” T encourages other pairs to comment.
Students
Each pair reports one or two ideas. Possible answer: “Bringing a reusable bottle reduces the carbon footprint because we need fewer disposable cups.”
Teacher
Step 4: Conclusion and assessment
T summarises the ideas and says: “Preventing waste is better than replacing things later. Today we will read a model project and then create our own.” T writes the title “Humans and the environment” on the board.
Students
Ss copy the title and the lesson focus into their notebooks.
