Student lesson
- Look for patterns in data.
- Answer the question with numbers.
- Say if the prediction is supported.
- Explain with science.
Words to know
something that repeats or changes in a regular way
what the evidence tells us
to back up with evidence
to give the reason why
1. Discover: The salty ice
Esi’s results: no salt, 12 minutes to melt; one spoon of salt, 9 minutes; two spoons, 7 minutes. “More salt means faster melting,” she says. Her prediction was that salt would speed melting. “The evidence supports it,” says her teacher. “Now explain why.”
Think: What numbers show the pattern?
2. Understand: Interpreting
Idea 1: Find the pattern
Look at the results. Do the numbers rise, fall or stay about the same? A pattern is the story in the data.
Idea 2: Write a conclusion
A conclusion answers the question. Include the pattern, the numbers and whether the prediction was supported: “More salt made ice melt faster: 12, 9 and 7 minutes.”
Idea 3: Explain with science
To explain, link to a science idea: salt lowers the freezing point of water so ice melts faster. Say clearly what the evidence does not show.
3. Worked examples
Example 1 (I show you): Pattern
12, 9, 7 minutes.
- Falling.
- Link to salt.
- Describe.
Answer: Melting time falls as salt increases.
Example 2 (We do it together): Support?
Predicted faster melting.
- Compare.
- Matches.
- Supported.
Answer: The prediction is supported.
Example 3 (You try): Explain
Why?
Show the steps and answer
- Salt lowers freezing point.
- So ice melts faster.
- Say it.
Answer: Salt lowers the freezing point of water.
Did you know?
Roads are salted in cold countries because salt makes ice melt at a lower temperature, which helps cars grip.
Why this matters
Interpreting evidence turns numbers into understanding.
4. Explore: Draw conclusions
Use given results to write a conclusion and an explanation.
- Read the data table.
- Describe the pattern.
- State if the prediction was supported.
- Explain with a science idea.
Think about it: what did you notice?
What did you notice? Numbers made conclusions stronger.
5. Practise
Say it in a sentence
Use these starters when you talk about the lesson. Say them out loud.
- A ___ is something regular in data.
- A ___ answers the question.
- Evidence can ___ a prediction.
- To ___ is to give a reason.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “A conclusion can ignore the data.” Use the data.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Interpret evidence and explain results.
- 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 learns to read evidence. You do not need to be an expert to help.
- Read a chart in a magazine.
- Ask “What pattern?”
- Look for numbers.
- 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: find a pattern in results; answer the question with evidence; say whether a prediction is supported; explain with science ideas.
Prerequisite knowledge. Grade 3 inquiry ideas: asking questions, predictions, fair tests, measuring, tables and simple conclusions.
Materials. Paper, pencils. 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 data cards.
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). Show a table and ask, “What story do the numbers tell?”
Explanation (10 min). Teach interpreting.
Guided activity (10 min). Learners write conclusions.
Independent activity (10 min). Learners swap and check.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What pattern? Supported? Why?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home 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 conclusion can ignore the data.” Use the data.
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. Interpret evidence and explain results. Enrichment. Look for one new example near your home or school, draw 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.
