Y07W02WR Understanding Urban Heat Islands

Part 1

How to Write

Informative – Informative report

An informative report presents organised information on a specific topic for a defined audience. It is written for readers who need clear, factual knowledge they can rely on. The tone is precise and impersonal — the writer’s role is to explain accurately, not to offer personal views.

  • Ideas & content: Select the most relevant facts for your topic and audience. Prioritise information that builds understanding, and leave out what does not serve the report’s purpose.
  • Structure & cohesion: Divide your report into clear paragraphs, each with a distinct focus. Open each paragraph with a topic sentence and use connecting words to link ideas across sections.
  • Voice & audience: Write in third person and maintain a consistently factual tone. Avoid personal opinions or casual phrasing — sound like someone who has researched carefully.
  • Language choices: Use precise, subject-specific vocabulary. Write in the present tense for facts and past tense for historical events. Vary sentence length to maintain readability.
  • Conventions: Spell all technical terms accurately. Use commas, colons and full stops correctly to present information clearly.

Common pitfalls: Including facts without connecting them to your purpose — each sentence should build the reader’s understanding, not just add detail. Losing paragraph structure — keep each paragraph focused on one clear idea.

Your Task Plan for Today

The brief

Question: Write a three-paragraph informative report for a local community newsletter explaining what urban heat islands are, why they form and what can be done about them. Select the most relevant and useful facts, organise them into a clear explanation and write entirely in your own words.

Stimulus: The following facts about urban heat islands have been gathered from a range of urban planning and climate sources. They are presented here without organisation.

- Dark surfaces such as bitumen and roofing absorb more heat than natural vegetation
- Cities can be between two and five degrees warmer than the surrounding countryside
- The urban heat island effect is strongest at night, when hard surfaces release stored heat
- Trees and parks lower local temperatures through shade and the evaporation of water from leaves
- Increased air conditioning use in cities contributes to warming by releasing heat into the surrounding air
- Green roofs have been shown to reduce building temperatures significantly
- Low-income neighbourhoods often have fewer trees and more heat-absorbing surfaces
- Heat-related illness and death are more common in dense urban areas during heatwaves
- Light-coloured or reflective road surfaces can reduce heat absorption
- More than half the world’s population now lives in cities
- Melbourne and Sydney have both documented measurable urban heat island effects
- Urban heat islands can intensify heatwaves, increasing health risk for vulnerable residents
- Some city councils have set targets for increasing tree canopy cover to reduce urban heat

Task Analysis: This task asks you to select and organise information from a list of facts into a clear, reader-friendly report for a community newsletter. Your audience has general interest but no specialist knowledge. A strong response selects the most relevant facts, organises them into three focused paragraphs and explains them in your own words.

Quick Plan

Plan your three paragraphs before writing:

  • Paragraph 1: What urban heat islands are and how they form
  • Paragraph 2: Why they are a serious problem (health, equity, etc.)
  • Paragraph 3: What can be done — practical solutions
  • Decide which facts to include and which to leave out.

Define the key concept

Open your report by explaining what an urban heat island actually is, in your own words. Your reader has no specialist knowledge — define the concept clearly before adding detail.

Paragraph focus

Each paragraph needs one clear idea, not a jumble of facts. Start each with a topic sentence that signals what the paragraph is about, then develop it with selected, relevant facts.

Tone & voice

Write for a general community audience — clear, factual and accessible. Avoid technical jargon without explanation. Write in third person throughout.

Ending technique

End your third paragraph on a constructive note — what can be done about the problem, or why it matters for the community. Leave the reader with something to think about.
