Giáo án A Closer Look 1

Ss activate prior knowledge about environmental problems and become familiar with the topic of the lesson.

T shows a picture of a polluted river and a picture of a wetland with birds. T asks Ss: What do you see in these pictures? What problems can you see? Ss list one or two problems in English or Vietnamese, and T writes useful ideas on the board, e.g. plastic waste, rubbish, dirty water.

A short list on the board of 3–5 environmental problems, such as: plastic waste, rubbish, polluted water, dead trees, endangered animals. Ss are ready to learn the six target words.

Ss understand the meaning and use of six topic words: habitat, endangered, reduce, reuse, pollution, ecosystem.

T presents each word with its example sentence:

• habitat (môi trường sống): A wetland is a habitat for birds.
• endangered (có nguy cơ tuyệt chủng): Some species are endangered.
• reduce (giảm): We reduce single-use plastic.
• reuse (tái sử dụng): Reuse a bottle when it is safe.
• pollution (ô nhiễm): Pollution harms river life.
• ecosystem (hệ sinh thái): An ecosystem connects living things and their environment.
  Ss repeat each word in chorus and individually, then complete Worksheet 1 in pairs by matching each word with its meaning. Then Ss check each meaning in the example sentence.

Worksheet 1 completed correctly:

• habitat – môi trường sống
• endangered – có nguy cơ tuyệt chủng
• reduce – giảm
• reuse – tái sử dụng
• pollution – ô nhiễm
• ecosystem – hệ sinh thái
  Ss can explain the meaning of each word from its example sentence.

Ss pronounce the consonant clusters /bl/ and /kl/ smoothly, linking the initial /l/ without inserting a vowel.

T models the words blue and clean slowly, then in natural sentences. T explains: /bl/ as in blue and /kl/ as in clean are initial consonant clusters. Link the first consonant to /l/ smoothly; do not insert a vowel. Ss practise: blue, clean, then 'The sky is blue.' and 'Please keep the room clean.' Then T plays the recording for items 5 and 6: Listen and type the word you hear. Ss type blue and clean.

Ss can say blue and clean with a connected initial cluster, e.g. 'The sky is blue.' 'Let's keep the classroom clean.' Ss type the correct words: 5. blue; 6. clean. Ss can explain: the first sound is a consonant cluster with /l/ linked smoothly and no extra vowel.

Ss consolidate the meaning of the vocabulary by choosing the correct word for each definition.

Ss do exercises 2, 3 and 4 from the textbook:
2. Choose the unit word or phrase meaning 'môi trường sống': habitat (A wetland is a habitat for birds.)
3. Choose the unit word or phrase meaning 'có nguy cơ tuyệt chủng': endangered (Some species are endangered.)
4. Choose the unit word or phrase meaning 'giảm': reduce (We reduce single-use plastic.)
Ss work individually, then check with a partner. Ss may also complete the interactive exercises on NeoEdu.

Answers:
2. habitat (A wetland is a habitat for birds.)
3. endangered (Some species are endangered.)
4. reduce (We reduce single-use plastic.)
Ss can use each word correctly in a sentence.

Ss use three target vocabulary items to write original topic sentences about protecting the school environment.

T models the language in the example: Our school can reduce waste through small, consistent actions. T asks Ss to write three original topic sentences, each using a different word from habitat, endangered, reduce, reuse, pollution and ecosystem. Ss may use ideas such as: We should reuse bottles at the canteen; Pollution from plastic harms the school pond; We can reduce rubbish by using refillable bottles.
Common mistake: Ss must write a complete sentence with a subject and a verb; do not translate Vietnamese word order directly. Homework: Ss write a short paragraph of 5–6 sentences about one action to protect the environment at home.

Each S writes three topic sentences, e.g.:

• We can reduce plastic waste by bringing a refillable bottle to school.
• Pollution harms the river life near our village.
• We should reuse paper boxes for storing books.
  Each sentence contains a correct target word and a complete clause.
