- Checklists catch gaps.
- Safety comes first.

checking what could go wrong
1. Discover: The planning sheet
Selam plans a test of whether a bigger parachute falls more slowly. She lists her question, variables, equipment and steps, drops each parachute three times, and checks she has thought about safety. “A plan is a map for the investigation,” she says.
Think: What would be missing if she forgot to repeat the drops?
2. Understand: Planning
Idea 1: Parts
A plan includes a question, hypothesis, variables, equipment, a numbered method, a results table and safety notes.
Idea 2: Repeats
Repeat each test at least three times, so one odd result does not mislead you.
Idea 3: Risk
A risk assessment asks what could go wrong and how to prevent it. Use safe heights, clear space and supervision.
3. Worked examples
Example 1 (I show you): List
Plan parts.
- Question.
- Variables.
- Method.
Answer: All parts.
Example 2 (We do it together): Add
Repeats.
- Three drops.
- Average.
- Reliable.
Answer: Repeat three times.
Example 3 (You try): Check
Safety.
Show the steps and answer
- Clear space.
- Low height.
- Adult nearby.
Answer: Safe plan.
Did you know?
Engineers and scientists write detailed plans so that others can repeat their tests exactly.
Why this matters
A good plan saves time and gives trustworthy results.
4. Explore: Parachute plan
Plan and run a test of parachute size with plastic bags, string and a small weight, dropping each from a low step three times and timing the fall.
- Write the plan.
- Check with the checklist.
- Run the test.
- Record in a table.
Think about it: what did you notice?
What did you notice? Bigger parachutes fell more slowly.

If a learner struggles
- Find the misconception: “A plan is not needed.” Needed.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Write a complete test plan.
- 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 plans a fair test. You do not need to be an expert to help.
- Ask “What is your plan?”
- Check safety together.
- Praise detail.
- 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.

Lesson objectives. Learners will: write a complete plan; include variables and repeats; include safety; check a plan with a checklist.
Prerequisite knowledge. Grade 5 ideas: fair tests, repeating measurements, recording data and drawing conclusions.
Materials. Plastic bags, string, weights, stopwatch. 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 a low step.
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). Ask, “What would you need to plan a fair race?”
Explanation (10 min). Teach planning.
Guided activity (10 min). Learners write plans.
Independent activity (10 min). Learners test.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Is anything missing? Is it safe?
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 plan is not needed.” Needed.
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. Write a complete test plan. 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.
