Informational Writing
What Is This?
Informational writing presents factual information about a topic in a clear, organised way. Its purpose is to teach the reader something they did not know — or to deepen their understanding of something they already know a little about. The author is not trying to persuade, entertain, or express feelings — the goal is clarity and accuracy.
Informational writing includes: reports, encyclopaedia entries, textbook passages, how-to guides, science explanations, news articles, and fact sheets.
Why Does It Matter?
Most of the writing demanded in school and professional life is informational. Learning to write informational text well means learning to think clearly, organise logically, use precise language, and present evidence accurately. These skills transfer to every subject: a science report, a history essay, a geography fact file, a technology manual — all are forms of informational writing.
The Structure of Informational Writing
Strong informational writing has a clear, predictable structure that helps readers navigate the content.
1. Introduction
The introduction tells the reader:
- What the topic is — the subject of the piece
- What the piece will cover — a brief overview of the main points
- Why it matters — why this topic is worth knowing about (optional but effective)
Example introduction: "The blue whale is the largest animal that has ever lived on Earth. This report explores what blue whales eat, how they communicate, and why they are still considered an endangered species despite decades of conservation efforts."
Notice: it names the topic, outlines the three main sections, and implies the significance (endangered despite conservation).
2. Body Paragraphs
Each body paragraph covers one main aspect of the topic. Each paragraph follows the same structure as any strong paragraph:
- Topic sentence — states what this paragraph is about
- Supporting details — facts, data, examples, explanations
- Concluding sentence — wraps up the paragraph
Group related information together. Do not jump between topics mid-paragraph.
3. Conclusion
The conclusion does not simply repeat the introduction. Instead it:
- Summarises the key points — briefly restates the most important information
- Highlights the significance — why does this matter? What should the reader take away?
- Leaves the reader with something — a memorable fact, a broader implication, a question for further thought
Using Text Features
Strong informational writing uses text features to help readers navigate and understand:
Headings and subheadings — divide the text into sections and signal what each section covers. Readers can find information quickly.
Bold or italicised vocabulary — highlights key terms the reader needs to understand.
Diagrams, charts, maps — present data or spatial information more clearly than prose alone.
Captions — explain what images or diagrams show.
Topic sentences — act as mini-headings within paragraphs.
Language for Informational Writing
Informational writing uses specific language choices that set it apart from narrative or persuasive writing:
Precise vocabulary
Use the exact word for the thing you are describing. Avoid vague words like "nice," "interesting," "some," or "a lot."
| Vague | Precise |
|---|---|
| "a lot of water" | "approximately 3.4 billion cubic kilometres of water" |
| "very hot" | "temperatures exceeding 450 degrees Celsius" |
| "some scientists" | "researchers at the University of Cambridge" |
Formal, neutral tone
Informational writing is objective — it avoids first person (I, we), emotional language, and personal opinion.
Avoid: "I think this is really amazing..." Use: "This phenomenon is remarkable because..." OR simply state the fact.
Present tense for facts
Facts about how things work are usually stated in the present tense. "Blue whales communicate using low-frequency sounds that can travel thousands of kilometres."
Passive voice (sometimes)
The passive voice shifts focus from who does something to what is done or what happens — useful when the doer is unknown or unimportant. "The samples were collected over a three-year period." (We do not need to know who collected them.)
Transition words for informational writing
- Adding information: also, additionally, furthermore, moreover, in addition
- Giving examples: for example, for instance, such as, to illustrate
- Explaining cause and effect: because, therefore, as a result, consequently
- Comparing: similarly, likewise, both, in the same way
- Contrasting: however, although, on the other hand, despite this
- Sequencing: first, next, then, finally, subsequently
Planning Before You Write
Informational writing requires planning. Before you write:
Step 1 — Identify your topic and audience. Who are you writing for? What do they already know? How much detail do they need?
Step 2 — Brainstorm what you know and identify what you need to research.
Step 3 — Organise your information. Group related facts together. Decide the order of your sections — usually most basic to most detailed, or most general to most specific.
Step 4 — Write a one-line plan. List your sections: Introduction → [Topic A] → [Topic B] → [Topic C] → Conclusion.
Worked Example: Planning a Report on Honey Bees
Topic: Honey bees
Audience: Grade 4 students
Sections:
- Introduction — what honey bees are and why they matter
- Life inside the hive — the three castes (queen, workers, drones)
- How honey is made — the process from nectar to honey
- Why bee populations are declining — threats (pesticides, habitat loss, disease)
- Conclusion — what can be done and why bees are worth protecting
Each section becomes one or more body paragraphs. Each paragraph has a topic sentence, supporting facts, and a closing sentence.
Common Mistakes
Mistake 1: Mixing opinion with information
Informational writing presents facts — not what the writer thinks about those facts. Opinions belong in persuasive writing. "I think bees are amazing" has no place in an informational report about bees.
Mistake 2: Disorganised sections
Information must be grouped logically. If a paragraph about bee anatomy includes a sentence about honey production, the writing lacks focus. Plan sections carefully and stick to one topic per paragraph.
Mistake 3: Vague language
Imprecise language ("a lot," "some," "many," "interesting") weakens informational writing. Use specific numbers, names, and technical terms wherever possible.
Mistake 4: No introduction or conclusion
Dropping straight into facts without context, or stopping abruptly without a conclusion, leaves the reader disoriented. Every piece of informational writing needs a beginning, a middle, and an end.
Mistake 5: Copying rather than paraphrasing
Good informational writers read their sources, understand them, and restate information in their own words. Copying text from a source is not informational writing — it is transcription.
