I. Objectives

1. Knowledge

By the end of the lesson, Ss will be able to:
Identify the three parts of an opinion essay (opening, development, closing) in the model text on local ecosystem restoration.
Explain how specific details such as the wetland example and the survey condition make an argument stronger than a general statement.
Use compound nouns such as nature reserve, food chain, greenhouse gas and wildlife protection accurately, and form their plurals correctly.
Write a short opinion paragraph or conclusion with a clear message, supporting details and a formal register.

2. Competences

a) General competences

Self-control and independent learning: Ss plan and check their own opinion writing using a checklist and revise their drafts without waiting for teacher correction.
Communication and collaboration: Ss work in pairs to compare answers, give constructive feedback on each other's summaries and report their findings clearly to the class.
Problem-solving and creativity: Ss choose a real local ecosystem issue, propose a realistic restoration measure and support it with specific, labelled details.

b) Specific competences

Communicative competence in English through listening, speaking, reading and writing: Ss read the model essay for purpose and audience, discuss its message aloud and write a coherent opinion text for a stated audience.
Language knowledge (pronunciation, vocabulary, grammar): Ss pronounce compound nouns with the correct stress, use key vocabulary (ecosystem, habitat, native species, restore, nature reserve) and apply the rule for plural compound nouns.

3. Personal qualities

Responsibility: Ss complete their individual writing task and homework on time and check that every detail they write is accurate and labelled as a proposal when it is not real data.
Diligence: Ss revise their drafts at least twice, checking meaning, sentence links and compound noun forms before handing them in.

Activity 1: Warm-up · 5 minutes

Ecosystem Snapshot

a) Aims

Ss activate prior knowledge of ecosystems and recall the key vocabulary of the unit before reading the model essay.

b) Content

Ss look at a photo of a local wetland (projected on the slide) and answer the questions: What living things can you see? Why is a wetland important to the local community? Ss brainstorm words related to the ecosystem, such as ecosystem, habitat, food chain, native species, restore and nature reserve.

c) Expected outcomes

A quick list of 5–8 ecosystem words on the board, and one or two sentences from each pair explaining why a wetland matters, for example: "A wetland gives a habitat to birds and fish, and it keeps the food chain balanced."

d) Organisation

Teacher's activities

Students' activities

Teacher
Step 1: Task delivering
T greets the class, shows the wetland photo and asks: "What can you see in this picture? Why is this place important to people living nearby?" T introduces the lesson aim: writing an opinion essay about funding local ecosystem restoration.
Students
Ss look at the photo and listen to the teacher's instructions. Ss confirm the lesson topic in their notebooks.
Teacher
Step 2: Task performance
T asks Ss to work in pairs for 2 minutes and write as many ecosystem words as possible. T walks around and encourages weaker Ss.
Students
Ss discuss in pairs and write words such as wetland, habitat, plants, birds, fish, food chain, pollution, restore. Some pairs may use Vietnamese terms to check meaning before writing English words.
Teacher
Step 3: Report and discussion
T invites 3–4 pairs to read out their words and sentences. T writes the key words on the board and asks the class: "Which words will help us write about funding?"
Students
Representative pairs read their answers. Expected answer: "A wetland is a habitat for many animals, and it supports the food chain." Other Ss add words such as native species or restore.
Teacher
Step 4: Conclusion and assessment
T confirms the correct meanings of ecosystem (hệ sinh thái), habitat (môi trường sống), food chain (chuỗi thức ăn), native species (loài bản địa), restore (phục hồi) and nature reserve (khu bảo tồn thiên nhiên). T says: "These words will appear in our model essay today."
Students
Ss copy the key vocabulary and their meanings into their notebooks and repeat the words after T.

Activity 2.1: Knowledge formation · 10 minutes

Reading the Model: Structure and Message

a) Aims

Ss identify the purpose, audience, opening, supporting details and closing of the model opinion essay and understand how they work together to create one clear message.

b) Content

Ss read the model opinion essay on local ecosystem restoration and complete Worksheet 1. Ss answer: (1) What is the purpose and who is the audience? (2) Which sentence is the opening substantive sentence? (3) Name two specific details that support the message. (4) Which sentence closes the essay without unsupported promises? Worksheet 1 is used in pairs.

c) Expected outcomes

Completed Worksheet 1 with the following answers:

Purpose: to argue that local ecosystem restoration deserves public funding when it is carefully planned and checked, not just a one-day planting event.
Audience: local readers, residents and decision makers who may fund or support the project.
Opening sentence: "Local ecosystem restoration deserves public funding when the work addresses a clear need and is checked carefully."
Specific details: "A healthy wetland can provide habitat and support natural processes that are difficult to replace" and "I would support a project that begins with a survey of existing conditions, uses specialist advice and publishes realistic measures of progress."
Closing sentence: "Restoration is a commitment to ecological function, not merely an attractive photograph or a large number of seedlings."

d) Organisation

Teacher's activities

Students' activities

Teacher
Step 1: Task delivering
T distributes Worksheet 1 and says: "Read the model text silently for 2 minutes. Then discuss the four questions with your partner. Find evidence in the text for each answer." T shows the three parts of an essay on the slide: opening, development, closing.
Students
Ss read the model text and listen to the instructions. Ss confirm the task and check the questions on the worksheet.
Teacher
Step 2: Task performance
T monitors pairs, prompts them to underline the key sentences and asks guiding questions such as: "Which sentence tells us the main idea?" and "Which sentence says what the writer would NOT accept?"
Students
Ss underline the opening sentence and the closing sentence, discuss the purpose and audience, and find the details in the body. Expected difficulty: Ss may confuse the purpose with the topic, so T reminds them that the purpose is what the writer wants the reader to think or do.
Teacher
Step 3: Report and discussion
T calls on two pairs to present their answers. T asks the class: "Do you agree? Why is the detail about the survey better than saying only that restoration is important?"
Students
Pairs report their answers. Expected answer: "The survey detail shows what a responsible project must do, so the reader can understand the standard the writer expects." Other Ss may add that the wetland detail gives a concrete reason.
Teacher
Step 4: Conclusion and assessment
T confirms the answers and summarises the structure: opening states the position, the body gives specific support and conditions, the closing restates the message without unsupported promises. T highlights the phrase "not merely" as a useful pattern for contrast.
Students
Ss correct their worksheets and note the three-part structure and the contrast pattern in their notebooks.

Activity 2.2: Knowledge formation · 7 minutes

Compound Nouns for Precise Meaning

a) Aims

Ss recognise compound nouns from the lesson, form their plurals correctly and choose a compound for meaning rather than placing any two nouns together.

b) Content

Ss complete Worksheet 2. Ss look at the compound nouns nature reserve, food chain, greenhouse gas and wildlife protection, decide whether each is written as one word, two words or with a hyphen, form the plural and mark the stress on the first element. Ss then write one sentence using a compound noun from the list.

c) Expected outcomes

Completed Worksheet 2 with the following answers:

nature reserve: two words; plural nature reserves; stress on NA-ture.
food chain: two words; plural food chains; stress on FOOD.
greenhouse gas: two words; plural greenhouse gases; stress on GREEN-house.
wildlife protection: one word for wildlife, protection as the head noun; no plural needed (uncountable use); stress on WILD-life.
Sample sentence: "Many native species depend on a healthy food chain in the nature reserve."

d) Organisation

Teacher's activities

Students' activities

Teacher
Step 1: Task delivering
T writes the four compound nouns on the board and asks: "Which word gives the main meaning? Which word changes in the plural?" T distributes Worksheet 2.
Students
Ss look at the compound nouns and read the instructions on Worksheet 2.
Teacher
Step 2: Task performance
T asks pairs to check the spelling in the textbook or dictionary and to say each compound aloud to decide the stress. T reminds Ss that spelling rules for compounds can vary.
Students
Ss work in pairs, complete the table and say the words aloud. Ss write one sentence using a compound noun.
Teacher
Step 3: Report and discussion
T asks a pair to read out the plural forms and the sample sentence. T listens for pronunciation and corrects the stress if needed.
Students
Ss report: "The plural of food chain is food chains." Expected sample sentence: "Greenhouse gases can harm the balance of an ecosystem."
Teacher
Step 4: Conclusion and assessment
T summarises the rule: the final noun usually determines the plural, and the stress often falls on the first element. T also reminds Ss to choose a compound because it has a precise meaning.
Students
Ss write the rule and the four compound nouns with their plurals in their notebooks.

Activity 3: Practice · 10 minutes

Summary and Conclusion Practice

a) Aims

Ss practise summarising the model accurately and writing a concluding paragraph that keeps the message and uses only details from the model.

b) Content

Exercise 5: Write a three-sentence summary using only information in the model. Keep any condition or limit that is essential to its meaning. Exercise 8: Write a short final paragraph or spoken conclusion that preserves the model's message. Use details already supplied, not invented results.

c) Expected outcomes

Exercise 5 sample answer: "Local ecosystem restoration deserves public funding when the work addresses a clear need and is checked carefully. A healthy wetland can provide habitat and support natural processes that are difficult to replace. Restoration is a commitment to ecological function, not merely an attractive photograph or a large number of seedlings."
Exercise 8 sample answer: "I would question a proposal that promises immediate recovery without evidence. Restoration is a commitment to ecological function, not merely an attractive photograph or a large number of seedlings."
Note: Ss' answers may differ in wording but must keep the condition "when the work addresses a clear need and is checked carefully" and must not add new results.

d) Organisation

Teacher's activities

Students' activities

Teacher
Step 1: Task delivering
T writes Exercise 5 and Exercise 8 on the board and reads the instructions. T emphasises: "Keep the condition. Do not invent new data."
Students
Ss read the two exercises and ask questions about any unclear words.
Teacher
Step 2: Task performance
T asks Ss to work individually for 4 minutes on Exercise 5, then exchange their work with a partner for 2 minutes to check meaning and the essential condition.
Students
Ss write three sentences for Exercise 5 and a short conclusion for Exercise 8. Partners check whether the condition and the message are kept.
Teacher
Step 3: Report and discussion
T calls on 2–3 Ss to read their summaries aloud. T asks: "Did you keep the condition when the work addresses a clear need?" T gives feedback on cohesion.
Students
Ss read their answers. Expected answer: "Restoration is a commitment to ecological function, not merely an attractive photograph." Other Ss comment on whether the condition is kept.
Teacher
Step 4: Conclusion and assessment
T shows the sample answers and explains that a good summary keeps the main idea and the essential condition but removes extra examples. T reminds Ss that a conclusion should restate the message, not add new facts.
Students
Ss compare their answers with the sample and revise any sentence that lost the condition or added unsupported results.

Activity 4: Application · 13 minutes

My Own Opinion Essay Plan

a) Aims

Ss plan and draft their own opinion paragraph on funding a real or realistic local ecosystem restoration project, using the structure and language of the model.

b) Content

Ss choose one local ecosystem issue (for example, a polluted pond, a damaged forest area or a river bank with erosion). Ss write an opening sentence stating their position, two specific supporting details (labelled as proposals if they are not real data), one condition for funding, and a closing sentence. Ss use at least two compound nouns from the lesson and at least three words from the vocabulary list. Ss share their plan with a partner and revise their draft with the checklist: Is my message clear? Is each detail specific? Is my register formal? Are my compounds correct?

c) Expected outcomes

A complete plan and draft paragraph of about 100–120 words, containing:

an opening sentence with a clear position on funding;
two specific details, labelled as proposals where needed;
one essential condition or limit;
a closing sentence that restates the message without unsupported promises;
at least two compound nouns from the lesson.

d) Organisation

Teacher's activities

Students' activities

Teacher
Step 1: Task delivering
T explains the task and shows the checklist on the slide. T says: "Choose a local problem you know. Write your position in one sentence first. Remember: label any example data as a proposal."
Students
Ss listen to the instructions, choose a local ecosystem issue and note the topic in their notebooks.
Teacher
Step 2: Task performance
T monitors individual work, helps Ss with word choice and checks the use of compound nouns. T asks guiding questions such as: "What specific detail can you add? What condition should the funding depend on?"
Students
Ss write their plan and draft paragraph. Expected example: "I would support a plan to restore the pond near our school if the project begins with a survey of the water quality and uses native species." Ss exchange drafts with a partner and check against the checklist.
Teacher
Step 3: Report and discussion
T invites 2–3 Ss to read their opening sentences aloud. T gives brief feedback on message, specific detail and register, and asks the class to identify one strong point in each.
Students
Ss read their opening sentences. Classmates comment: "Your detail is specific because you name the species."
Teacher
Step 4: Conclusion and assessment
T summarises the key points: a strong opinion essay has a clear message, specific and labelled details, a condition, and a formal register. T asks Ss to complete the final draft at home and to check their work on the NeoEdu page.
Students
Ss note the checklist items and the homework instructions in their notebooks.
