- Choose equipment that suits the measurement.
- Repeat to check results.
Words to know
a set of steps decided before starting
the steps followed in an investigation
the tools and materials used
to do a test more than once
1. Discover: The melting ice plan
Esi wants to find out whether salt changes how fast ice melts. She writes her plan: question, prediction, equipment (three cups, ice cubes, salt, timer), method, safety and what she will record. “A plan is like a recipe,” says her teacher. “Another group should be able to follow it.”
Think: Why must the method be clear?
2. Understand: Planning
Idea 1: Parts of a plan
A plan includes the question, a prediction, equipment, the method, safety notes and a results table prepared in advance.
Idea 2: Writing the method
Number the steps. Use exact amounts and times, for example “add 1 teaspoon of salt”. Another person should be able to follow your method and get a similar result.
Idea 3: Repeating
Repeat each test at least three times. If results are close we can trust them more. If they are very different, we look for what went wrong.
3. Worked examples
Example 1 (I show you): Equipment
Measure 100 mL water.
- Need a measuring jug.
- Pick the right size.
- Write it down.
Answer: Measuring jug or cylinder.
Example 2 (We do it together): Steps
Order: pour, add salt, start timer.
- Put in order.
- Number them.
- Check.
Answer: 1 pour, 2 add salt, 3 start timer.
Example 3 (You try): Repeats
How many times?
Show the steps and answer
- At least three.
- Record each.
- Compare.
Answer: Three repeats at least.
Did you know?
Scientists at big laboratories write detailed plans so that other labs can repeat their work and check their results.
Why this matters
A clear plan saves time, keeps us safe and makes our results trustworthy.
4. Explore: Plan an investigation
Write a plan for “Does the size of a ramp change how far a toy car rolls?”
- Write the question and prediction.
- List equipment.
- Number the method steps.
- Draw a results table and note safety.
Think about it: what did you notice?
What did you notice? Planning showed what we had missed.

If a learner struggles
- Find the misconception: “We can plan while testing.” Plan first.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Plan an investigation with a clear method.
- 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 plan an investigation. You do not need to be an expert to help.
- Plan a kitchen test together.
- Ask “Could someone repeat it?”
- Use safe items.
- 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: list plan parts in order; choose suitable equipment; write clear method steps; include safety and repeats.
Prerequisite knowledge. Grade 3 inquiry ideas: asking questions, predictions, fair tests, measuring, tables and simple conclusions.
Materials. Notebooks, 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. Print plan templates.
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 recipe and ask, “Why do recipes have steps?”
Explanation (10 min). Teach planning.
Guided activity (10 min). Learners write plans.
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. Could someone else follow it?
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. “We can plan while testing.” Plan first.
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. Plan an investigation with a clear method. 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.
