Sustainable Development — English Bac STM

This theme feeds the Reading and Writing sections of the Bac STM English paper (coefficient 2), where a precise word field makes an answer stronger. Solar panels in the Moroccan desert, waste sorting, cutting the carbon footprint: Sustainable Development is where English environmental vocabulary meets the science content many candidates already study.

English carries a coefficient of 2 in the Bac Sciences et Technologies Mécaniques (STM) stream. The core subjects are Mathematics and Engineering Sciences (coefficient 7 each), then Physics-Chemistry (coefficient 5). English and Philosophy (coefficient 2) form the margin where candidate rankings and honours are settled. Mastering the structure of a piece of writing matters more here than memorising it.

في الامتحان

Three parts: Reading Comprehension, Language, and Writing (about 180 words). Reading technical drawings and function diagrams builds the same skill an essay needs: breaking an argument into parts and rebuilding it as a coherent plan.

أهداف التعلم

  • Reuse this vocabulary field in the Bac STM Reading answers and in the argumentative essay (coefficient 2)
  • Use energy and climate vocabulary: renewable / fossil energy, carbon footprint, greenhouse gas emissions, global warming
  • Name environmental issues: pollution, deforestation, water scarcity, loss of biodiversity, waste
  • Define sustainability: meeting present needs without compromising future generations
  • Argue how economic development and environmental protection can be reconciled

المفاهيم الأساسية

Energy and carbon footprint

renewable energy (solar, wind, hydro) vs fossil fuels (coal, oil, gas); carbon footprint (the total greenhouse gas emissions caused by a person, product or activity); to reduce / offset emissions.

Environmental issues

air and water pollution, deforestation, water scarcity, loss of biodiversity, plastic waste, soil degradation — the problems sustainable development aims to address.

Sustainability: economy and environment together

sustainable development = development that meets present needs without compromising the ability of future generations to meet theirs. It seeks a balance between economic growth, social fairness and environmental protection.

الأخطاء الشائعة

1

Confusing renewable (naturally replenished: sun, wind) and non-polluting: nuclear power is low-carbon but not renewable; biomass is renewable but can pollute.

2

Using pollution as a countable noun: say “air pollution” / “levels of pollution”, not “pollutions”.

3

Treating sustainable development as “stopping all development”: it is about developing differently, not stopping.

مثال محلول

نص السؤال

Write a sentence explaining how a country can pursue economic growth while lowering its carbon footprint.

التصحيح

Name the tension. Growth usually means more energy use; a lower carbon footprint means fewer emissions.
Give the reconciling idea. Shifting energy sources from fossil fuels to renewables allows both at once.
Result. “A country can keep growing economically while cutting its carbon footprint by investing massively in renewable energy, so that new industries and homes are powered by solar and wind rather than by coal and oil.”

3 تمارين للتدرب

التمرين 1

Easy
Classify as renewable or fossil: solar, coal, wind, oil.
عرض التصحيح
Renewable: solar, wind. Fossil: coal, oil.

التمرين 2

Medium
Complete: “Cycling to school instead of being driven reduces your ___.” (carbon footprint / biodiversity / deforestation)
عرض التصحيح
carbon footprint — cycling produces no emissions, so it lowers the greenhouse gases you are responsible for.

التمرين 3

Hard
Explain in one sentence why the definition of sustainable development refers to “future generations”.
عرض التصحيح
Because sustainability is about fairness over time: using resources and polluting today at a rate that leaves future generations unable to meet their own needs would not be development, but a transfer of the cost onto people who cannot object.

الأسئلة الشائعة

How does this theme connect to the science subjects?

Energy sources, greenhouse gases and pollution are studied in physics-chemistry and life-and-earth science; this chapter gives candidates the English vocabulary to bring that knowledge into an essay with concrete, credible examples.

Is Morocco a good example for this theme?

Yes — the Noor solar complex near Ouarzazate, wind farms, and water-scarcity policy are specific, current Moroccan examples that make an essay stronger than generic ones.

What are the three pillars of sustainable development?

Economic (growth and jobs), social (fairness, health, education) and environmental (protecting resources and ecosystems) — a good answer keeps all three in view rather than only the environment.

English is far from my mechanical specialism — how do I approach it?

Treat it as a system with inputs and outputs: the input is a prompt, the processing is analysis then discussion, the output is a conclusion that settles the question. Learn that flow, apply it to the 31 chapters with two examples each, and one weekly session is enough to raise the mark.

How do I use this theme in the Bac STM essay without sounding generic?

Anchor each key term in one concrete, personal example — a place, a person, a situation you know. A specific illustration in accurate English scores better than a long list of terms with no support, on any of the society prompts in the programme.
