Student lesson
- Record results neatly in a table.
- Bar graphs make comparing easy.
- Always include units.
- Conclusions use the evidence.
Words to know
rows and columns of data
a chart with bars for amounts
what a measurement is counted in
what the evidence tells us
1. Discover: The results chart
The class tests three bridge designs: arch 12 coins, beam 8 coins and truss 20 coins. Esi puts them in a table and draws a bar graph. “The truss bar is tallest,” she says. “So the truss held the most.”
Think: What is the conclusion?
2. Understand: Records
Idea 1: Tables
A table has headings, rows and columns. Put the design in one column and the result in the next. Write the unit, such as coins or grams.
Idea 2: Bar graphs
A bar graph uses a bar for each design. Taller bars mean larger results. Label both axes and give the graph a title.
Idea 3: Conclusions
A conclusion says what the evidence shows. Start with the result, then give numbers: the truss held 20 coins, more than the arch (12) or beam (8).
3. Worked examples
Example 1 (I show you): Table
Design and coins.
- Headings.
- Rows.
- Units.
Answer: Use headings and units.
Example 2 (We do it together): Graph
Bars 12, 8, 20.
- Tallest.
- Label.
- Title.
Answer: Truss has the tallest bar.
Example 3 (You try): Conclude
Truss best.
Show the steps and answer
- Result.
- Numbers.
- Compare.
Answer: Use the numbers in the conclusion.
Did you know?
Engineers keep careful records called logbooks so that others can repeat their work years later.
Why this matters
Clear records let us compare designs fairly and share what we learned.
4. Explore: Chart the results
Record three designs in a table and draw a bar graph.
- Draw a table with headings.
- Enter each result with units.
- Draw a bar graph.
- Write a conclusion.
Think about it: what did you notice?
What did you notice? The graph made the best design easy to see.

If a learner struggles
- Find the misconception: “A conclusion is a guess.” It uses evidence.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Record data and write conclusions.
- 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 records results in tables and graphs. You do not need to be an expert to help.
- Make a table together.
- Ask, “What does the graph show?”
- Check units.
- 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: make a results table; draw a bar graph; include units; write a conclusion.
Prerequisite knowledge. Grade 3 science ideas from earlier units: asking questions, fair tests, properties of materials, forces and recording results.
Materials. Graph paper, pencils, rulers. 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. Print graph grids.
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 bar graph and ask, “What does it tell us?”
Explanation (10 min). Teach recording.
Guided activity (10 min). Learners chart.
Independent activity (10 min). Learners conclude.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What do the numbers show?
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 is a guess.” It uses evidence.
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. Record data and write conclusions. 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.
