Informative Writing, Research and Grammar: Grade 7 Study Guide
Informative writing explains a topic clearly using well-chosen facts and examples.
An informative essay introduces a topic with a clear thesis, develops it with facts, definitions, details and quotations, organizes ideas logically with transitions, and ends with a conclusion. A formal style and precise vocabulary keep the writing professional.
Research means asking a focused question, gathering information from several sources, checking that each is credible, taking notes in your own words and giving credit with a citation to avoid plagiarism.
From question to essay
How do volcanoes shape land?
Books, reliable sites, interviews.
Record the source of each fact.
Thesis, body paragraphs, conclusion.
Credit your sources.
Judging sources
Ask: Who wrote this and are they an expert? When was it written? Is it supported by evidence? Is it trying to sell something? Websites ending in .gov or .edu and established encyclopedias are often reliable, but check each one. Compare at least two sources for any key fact.
| Source | Strength | Check |
|---|---|---|
| Textbook or encyclopedia | overview | date and edition |
| Government or university site | data, research | author and date |
| News article | recent events | bias, sources named |
| Personal blog or social media post | opinion | usually not reliable for facts |
Phrases, clauses and sentence variety
A phrase lacks a subject-verb pair (after the storm); a clause has both. Combine them to create simple, compound, complex and compound-complex sentences. Use commas to separate coordinate adjectives (a cold, dark night), after introductory clauses and before a conjunction joining two clauses. Check that modifiers sit next to what they describe: 'Running down the hall, the bell rang' is a misplaced modifier.
Worked example and common mistakes
Example: Thesis: 'Volcanoes both destroy and create land.' Body paragraph 1 gives an example of destruction (Mount St. Helens, 1980), paragraph 2 an example of creation (the Hawaiian Islands). Common mistakes: copying text, listing facts with no thesis, trusting the first search result and using a comma splice. Read your essay aloud to find missing transitions.
