The Future of Food
A complete two-session C1 lesson on how technology and the climate are reshaping what we eat — lab-grown meat, insect protein, vertical farming and the ethics behind them. The language engine is speculative and evaluative: the language of weighing an innovation's upsides against its downsides and arriving at a balanced verdict. Includes a featured interactive reading, audio scripts, the Sustainable Restaurant Challenge, answer keys, and a self-grading workbook.
Can-Do Statements
By the end of this lesson, students will be able to:
- Discuss the future of food — sustainability, biotechnology and food systems — with precision.
- Use advanced food vocabulary — lab-grown meat, alternative protein, vertical farming, carbon footprint, food security, regenerative agriculture.
- Speculate and evaluate (one possible outcome might be…, the upside is…, on balance…).
- Weigh competing arguments in a debate and reach a reasoned, balanced verdict.
- Read a discursive article critically, separating arguments for an innovation from arguments against it.
- Write a balanced opinion essay (150–200 words) that weighs pros and cons before deciding.
Vocabulary & Functional Phrases
This language set is shared across the lesson plan, the workbook flashcards, and the reading article.

- Some experts claim…, while others counter…
- It's worth weighing… against…
The Engine of the Lesson
New food technologies are neither all good nor all bad. At C1, the skill is to speculate about what they could do and then evaluate — weigh the trade-offs and commit to a reasoned position.
1. Speculative language
We're talking about a future that doesn't exist yet, so the verbs and modals must signal possibility, not fact.
| possible futures | Lab-grown meat could / might cut emissions dramatically. |
| tentative outcomes | One possible outcome might be cheaper protein for everyone. |
| report claims | Some experts claim it's safe; others counter that we don't yet know. |
2. Evaluative language
An evaluation names the benefits and the costs, then judges which wins. This is what turns an opinion into an argument.
| name the trade-off | The upside is lower emissions; the downside is the cost. |
| weigh and decide | On balance, the benefits seem to outweigh the risks. |
| concede then commit | While this might sound extreme, it's worth taking seriously. |
3. Emphasis — cleft sentences
To foreground what's really at stake, reshape the sentence.
Trap: "could" is not the same as "will". An evaluation built on speculation must keep that distinction visible. "Lab meat will save the planet" overclaims; "Lab meat could make a real difference, on balance, if it scales" is the C1 move.
Would You Eat a Lab-Grown Burger?
A fresh, balanced interactive article on cultured meat — the promise of feeding billions with a fraction of the land and emissions, and the real obstacles of cost, regulation and our deep feelings about "natural" food. It carries the unit's vocabulary and the speculate-and-evaluate language.
What's inside
- A C1 essay on lab-grown meat, alternative protein, sustainability and the ethics of future food.
- Inference-based comprehension with instant feedback and a CEFR-style score.
- A "argument for vs argument against" sorting task that trains balanced reading.
- A glossary, a key statistic, and a vocabulary flashcard deck.
How to use it: project it for shared reading, or assign it before class. Students read, tap Show My Score, and bring their verdict to the restaurant challenge.
Open the Reading →Timed Lesson Stages
Each stage lists timing, teacher instructions, and the interaction pattern. Student talking time is high throughout.
1. Hook — Would You Eat It?
Show (or describe) three plates: a cricket-flour cookie, a lab-grown chicken nugget, a 3D-printed steak. Ask students to rank them from "I'd try it tomorrow" to "never". Quick poll, then a few reasons. The instinctive reactions open the door to evaluating with reasons, not just gut feeling.
Interaction: Pairs → whole class.
2. Vocabulary — The Language of Future Food
Introduce the C1 set in context (sustainability, food security, lab-grown meat, alternative protein, vertical farming, carbon footprint, regenerative agriculture). Elicit meaning from examples, then ask: "Which of these is already happening in your country? Which sounds promising, and which sounds worrying?"
Interaction: Teacher → class → pairs.
3. Language Focus — Speculate & Evaluate
Take "Lab meat is unnatural" and "Lab meat will save the planet" and ask the class to make both more balanced. Elicit speculative modals ("could", "might") and evaluative phrases ("the upside is", "on balance"). Build the toolkit, then students rewrite three blunt food opinions from the workbook.
- Concept check: "Is this a fact or a possibility? Has the speaker weighed both sides?"
- Controlled practice: workbook for/against sorting and sentence-building tasks.
Interaction: Guided discovery → individual.
4. Speaking — Upside / Downside Drill
A warm-up for the centerpiece (full rules in Activities). A student draws a food innovation and must give one upside, one downside, and a balanced verdict ("on balance…"). The group checks that both sides were weighed.
Interaction: Small groups.
5. Wrap-Up & Set Reading
Each group shares the most balanced verdict they heard. Assign the interactive reading so students arrive at Session 2 with a position on lab-grown meat.
1. Review — For or Against?
Read out six statements about lab-grown meat. Students label each as an argument for or against, and identify the signal language. Sharpens the balanced-reading lens before the project.
Interaction: Whole class.
2. Reading — Would You Eat a Lab-Grown Burger?
Use the interactive reading page (linked above). Students complete the inference comprehension and the "for vs against" sorter, then compare answers.
- Pre-reading: predict whether the writer ends up for or against — or undecided.
- While reading: mark the single strongest argument on each side.
- After: tap Show My Score and decide your own verdict.
Interaction: Individual → pairs.
3. Project — The Sustainable Restaurant Challenge
The centerpiece (full instructions in Activities). Groups design a futuristic, sustainable restaurant — name, menu and practices — then pitch it, justifying each choice with evaluative language.
Interaction: Groups, then whole-class pitches.
4. Writing — A Balanced Verdict
Students begin a 150–200-word opinion essay (finished for homework): "Would you support the sale of lab-grown meat in your country?" The brief: weigh at least one upside and one downside before committing to a verdict.
Model opening: "I'll admit my first reaction to lab-grown meat was a slight shudder — there's something about the word 'lab' next to the word 'dinner'. And yet, the more I weigh it up, the harder that instinct is to defend. The upside is enormous: a fraction of the land, water and emissions of conventional farming. The downside — cost, regulation, and our discomfort — is real but, on balance, surmountable."
- Target: a clear verdict, one upside, one downside, speculative modals, five unit vocabulary items.
- Students self-check against the workbook checklist, then review the flashcards.
Interaction: Individual.
5. Reflect & Score
Exit ticket: "Has your opinion about future food shifted today — and what tipped the balance?" Students tap Show My Score in the workbook and show you the result.
Speaking Activities
The centerpiece is The Sustainable Restaurant Challenge. Rotate the warm-ups and games below across lessons.
The Sustainable Restaurant Challenge
Groups of three or four. Goal: design and pitch a futuristic, sustainable restaurant, justifying every choice with evaluative language.
- In groups, design a restaurant of 2050. Decide on a name and theme, a short menu using future ingredients (lab-grown meat, insect protein, vertical-farm greens), and three sustainable practices (zero waste, solar kitchen, local sourcing).
- For each menu choice, the group must say the upside and acknowledge a downside ("The upside is a tiny carbon footprint; the downside is that some diners may hesitate").
- Optional twist: give each group a customer profile to cater to — a vegan athlete, a picky child, an environmentally-conscious grandparent.
- Groups pitch their restaurant to the class (90 seconds). Listeners ask one probing question each.
- The class votes for the most convincing and most genuinely sustainable concept — the teacher scores the quality of the evaluation, not the flashiness of the idea.
More Activities (rotate these)
Upside / Downside
A student draws a food innovation (insect flour, GM crops, 3D-printed meals). They give one upside, one downside, and a balanced verdict. The group rates whether both sides were genuinely weighed.
De-blunt the Opinion
Each pair gets four blunt food opinions ("Insect food is disgusting"). They race to rewrite each as a balanced, evaluative version. Sharpest rewrites are read aloud and voted on.
Feed Nine Billion
Groups have one minute to propose how to feed a growing planet using two unit ideas (vertical farming, alternative protein). They pitch; the class probes for the hidden downside.
The Taste Test Time Capsule
Each student gives a 90-second talk: "What I think my grandchildren will eat — and won't." The partner listens for one speculation and one evaluation, then asks a follow-up.
Audio & Transcripts
Tap a transcript to open it. Add your recording in the player, and use the same file in the student workbook's Listening task.
Audio 1The Strangest Thing I've Eaten (model)+
The strangest thing I've ever eaten was a cricket taco, of all things. I was traveling, and honestly I only tried it to be polite. It was… fine. Better than fine, actually. And it made me think. The upside of insect protein is obvious once you look at the numbers — a fraction of the land and water of beef. The downside is purely in our heads: it just feels wrong to a lot of us. On balance, though, I suspect that's a feeling we could get over, the same way we got over eating raw fish.
How to use: Play once as a model before the Upside/Downside drill. Ask students to catch the evaluative language ("the upside is", "the downside is", "on balance").
Audio 2Would You Try Lab-Grown Meat? (listening task)+
Dan: Apparently you can now buy chicken grown from cells, no farm involved. Honestly? I'd try it.
Yuki: Really? I'm not sure. The upside is clear — it could slash emissions. But it feels so… processed.
Dan: That's fair. Although, to be fair, normal supermarket meat isn't exactly natural either.
Yuki: True. I suppose my real worry is the cost. Right now it's incredibly expensive to make.
Dan: For now. But the price could fall fast if it scales up. On balance, I think the benefits outweigh the downsides.
Yuki: Maybe. I'd want to see the regulation sorted out first, though.
How to use: Source audio for the workbook's Listening task. Two voices work best. Play for gist ("Who is more cautious?"), then for the evaluative language ("The upside is…", "on balance…", "the benefits outweigh the downsides").
Audio 3Pronunciation — weak forms in evaluation (optional)+
Listen-and-repeat. Evaluative phrases ride on weak, fast function words; the stress lands on the content word.
The UPside is… — The DOWNside is… — On BALance… — the benefits OUTweigh the risks — while this might sound exTREME…
How to use: C1 students often say these word-by-word, which kills the fluency. Drill them as single rhythmic units so the evaluation sounds natural and considered.

Vocabulary in Context
- Growing crops in stacked layers indoors, often in cities, is vertical farming.
- The total greenhouse gases caused by a product is its carbon footprint.
- Plant- or insect-based substitutes for meat are alternative protein.
- Making sure everyone has reliable access to enough food is food security.
- Farming that restores soil and ecosystems is regenerative agriculture.
Expressing Nuance — Blunt vs Balanced (sorter)
- Blunt / overstated: "Lab meat is completely unnatural." · "Eating insects is disgusting." · "GM crops are obviously dangerous."
- Balanced / evaluative: "Some find lab meat hard to accept at first." · "Insect protein may feel culturally unfamiliar." · "GM crops carry both benefits and risks worth weighing."
Build the Sentence (word order)
- On balance the benefits seem to outweigh the risks.
- What the planet needs is a smaller carbon footprint.
Reading Page — Comprehension

- Argument against (for now): very expensive to produce · heavily processed / regulation unclear · many people find it off-putting.
Common Student Errors
Watch for these at C1 and correct gently in the moment.
| Typical Error | Stronger C1 Version | Why & How to Fix |
|---|---|---|
| "Lab meat will save the planet." | "Lab meat could make a real difference." | Speculation, not fact. Use "could / might", not "will". |
| "The foods are more healthier." | "The food is healthier." | Double comparative; "food" is uncountable here (no plural). |
| "If it would be cheaper, I will buy it." | "If it were cheaper, I would buy it." | Second conditional for speculation: if + past, would + base. |
| "It depends of the price." | "It depends on the price." | Dependent preposition: "depend on". |
| "a meat / two meats" | "meat / some meat (uncountable)" | Uncountable — no article, no plural. |
| "In one hand… in other hand…" | "On the one hand… on the other hand…" | Fixed phrase — drill the prepositions and "the". |
