Student lesson
- Reliability can be tested.
- Origin and purpose matter.
- A biased source can still be useful.
- Reliability depends on the question.
Words to know
able to be trusted because it is accurate and well based
the origin and history of a source: who made it and where it has been
a leaning that can make a source unfair
the reason a source was made
1. Discover: The poster and the log
Ms Smith shows two model sources about a harbour: a poster that advertises a ferry, and a harbour master’s daily log of ships. “Which one is more reliable for the number of ships?” she asks. “The log,” says Abu, “because it was kept to record facts.” “And the poster?” “It is made to persuade people to buy tickets,” says Mei. “But it still tells us that people travelled by ferry,” says Ms Smith. “Reliability depends on what you want to know.”
Think: When can a biased source still be useful?
2. Understand: Source reliability
Idea 1: Origin and purpose
The provenance of a source is its origin: who made it, when, where and how it has been kept. Ask about its purpose. A source made to record facts, such as a log, may be more reliable for those facts than a source made to persuade, such as an advertisement. Look for bias, such as one-sided words or things left out.
Idea 2: The four-question test
Use four questions: Origin (who made it and did they know?), Purpose (why was it made?), Content (is it detailed, sensible and balanced?) and Check (do other sources agree?). The more questions that give good answers, the more reliable the source is likely to be.
Idea 3: Reliability and use
No source is perfect. Even an unreliable source can be useful for a different question. A poster may be a poor guide to prices but good evidence of how a company wanted to look. Decide which question you are asking, then judge which sources suit it best.
3. Worked examples
Example 1 (I show you): Name
The four questions.
- Think.
- List.
- Check.
Answer: Origin, purpose, content, check.
Example 2 (We do it together): Decide
Is an advert reliable for exact facts?
- Think.
- Say.
- Check.
Answer: Not always.
Example 3 (You try): Explain
Why a biased source can be useful.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: It shows opinions of the time.
Did you know?
Fact-checkers and librarians use steps like these to test whether information online or in books can be trusted.
Why this matters
Testing sources protects you from false claims and helps you choose the best evidence.
4. Explore: Reliability test
Use the four-question test on two model sources about one topic. Give each a rating (high, medium, low) for a stated question and explain your reasons.
- Test.
- Rate.
- Explain.
- Share.
Think about it: what did you notice?
What did you notice? Ratings change with the question.
5. Practise

If a learner struggles
- Find the misconception: “A source is either reliable or not.” It depends on the question.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a four-question card.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child tests sources. Please ask how we know when we read claims. You do not need to be an expert to help.
- Ask who made it.
- Look for another source.
- Think about purpose.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: define reliable, provenance, bias, purpose; apply a four-question test; explain usefulness vs reliability; judge sources for a question.
Prerequisite knowledge. Grade 5 ideas: enquiry, primary and secondary sources, oral history and written records.
Materials. Model sources, charts. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare two model sources.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Tell the poster and the log story.
Explanation (10 min). Teach source reliability.
Guided activity (10 min). Reliability test.
Independent activity (10 min). Discuss.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How do we judge whether a source can be trusted?
Teacher explanation notes. Start with a picture, story, map or local example. Then talk about what was seen, then draw and write. Always ask “how do you know?” and invite more than one view. Treat every family, culture and community with respect, and never ask learners to share private information.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use pictures, maps, real objects and short sentences, and let learners work with a partner. Let learners point, show, act or draw instead of writing. Extension. Ask learners to find a new example from their own community and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “A source is either reliable or not.” It depends on the question.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Make a four-question card. Enrichment. Find one new example near your home or school, draw or write about it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
