Y07W02PA - Understanding Urban Heat Islands

This week you wrote an informative report for a community newsletter on urban heat islands. Now you'll read another student's report and decide how well it works. Studying someone else's writing sharpens what you notice — and gives you moves to use in your own.

Part 1

The Assessor Scorecard for

Informative – Informative report

Markers look for newsletter writing that combines clear, well-organised facts with language pitched at a mixed audience. Check each strand below to see what strong work looks like.

Ideas & Content

Facts chosen for what the audience actually needs to know. Accurate information explained clearly enough to understand. A reason the topic matters to the reader.

  • Relevance to audience: and purpose.

Structure & Cohesion

Ideas flow logically from one paragraph to the next. Each paragraph has one clear focus. Transitions guide the reader through the explanation.

  • Logical sequencing of: ideas.

Audience & Purpose

Tone and detail pitched at a mixed community audience. Language clear without sounding too simple. A clear reason readers should care about the topic.

  • Audience-appropriate tone and: detail.

Language Choices

Clear, precise vocabulary that explains without jargon. Sentences varied enough to hold interest. Concrete examples and specific details over telling.

  • Precise and accessible: language.

Conventions

Correct spelling, punctuation and grammar throughout. Varied, controlled sentence construction. Standard conventions so readers focus on the ideas.

  • Accurate spelling and: punctuation.

Part 2

Today’s Marking Targets

Task in one sentence

Write a three-paragraph report for a community newsletter explaining what urban heat islands are, why they form and what can be done about them.

Let’s Focus

Two strands matter most this week: Structure & Cohesion and Ideas & Content. Your report had to move readers through three ideas — what, why, what to do — step by step. You also had to pick the facts that mattered most for a general reader.

Structure & Cohesion

Strong writing organises the three parts of the explanation — what, why, what to do — into clear paragraphs with smooth transitions. Readers follow the progression without getting lost. Sentences inside each paragraph connect naturally and build understanding.

What markers scan for

  • Information split clearly across the three paragraphs.
  • Ideas connected between paragraphs, not just stacked.
  • Each paragraph holds one clear focus.
  • Transitions guide the reader forward at each turn.

Score Bands

  • Basic

    Information sits in separate sections but links between ideas are unclear; readers may lose the thread.

  • Strong

    The three main ideas sit in logical paragraphs with smooth transitions; readers follow easily from start to finish.

  • Excellent

    Paragraphs flow with purpose; each one builds on the last to deepen understanding of the topic.

Ideas & Content

Strong writing picks facts that genuinely help a newsletter audience understand the topic. The writer explains why those facts matter and skips irrelevant detail. Explanations stay specific enough to be useful but clear enough for a general reader.

What markers scan for

  • Facts chosen for what the audience actually needs.
  • Explanations clear enough for a general reader.
  • No irrelevant detail or assumed background knowledge.
  • Specific examples that make the science concrete.

Score Bands

  • Basic

    Facts appear but some stay unclear or thinly explained; the audience may miss the main ideas.

  • Strong

    Facts are relevant and well explained; the audience understands what heat islands are, why they form and what helps.

  • Excellent

    Facts are carefully chosen and explained with specific examples; the writing is informative and accessible.

Student sample for assessment

Written by a Year 7 student in Footscray, Victoria, Australia.

Have you noticed that your neighbourhood feels warmer on summer nights than the countryside outside the city? That difference is an urban heat island. Cities are typically two to five degrees warmer than surrounding rural areas, especially after sunset. This happens because cities are built differently from natural environments. Dark surfaces like bitumen roads and concrete absorb and store heat from the sun much more effectively than vegetation does. While a park or farm reflects some heat back into the atmosphere, a street absorbs it and releases it slowly throughout the night. Understanding why heat islands form helps us see why they are a problem. During the day, these dark surfaces act like giant heat collectors. At night, they release all that stored energy, making cities uncomfortable and driving up demand for air conditioning. This creates a cycle where more people use more electricity, which generates more heat and pollution. Trees and green spaces break this cycle because they provide shade and release moisture through a process called evaporation, which naturally cools the air around them. Melbourne and Sydney have both measured this effect and found that green spaces can reduce local temperatures significantly. Fortunately, cities have several ways to fight heat islands. Planting more trees and creating parks obviously helps, but some solutions are more surprising. Light-coloured road surfaces reflect heat rather than absorbing it, and some cities are testing these alternatives. Building green roofs covered in plants is another emerging solution that reduces the temperature inside buildings and contributes to cooling the surrounding area. The most effective approach combines several strategies: more vegetation, lighter surfaces and better urban planning. By understanding how cities create their own heat, communities can make choices that benefit both residents and the environment.
