- Reflect and share.
Words to know
a larger task done in stages
to share work with others
to think about what went well
the best version after improvements
1. Discover: The school bridge project
The class is asked to build a model bridge over a classroom stream made of blue paper. Groups define the problem, sketch, build, test, improve and record. At the end, each group presents its graph and says what it learned. “We would test more designs next time,” says Selorm.
Think: What would you do next time?
2. Understand: Project
Idea 1: The whole process
In your project you define, design, build, test, improve and record. Keep a notebook of every step.
Idea 2: Presenting
To present, explain the problem, show your design, share the test graph and say how you improved. Speak clearly and thank listeners.
Idea 3: Reflecting
To reflect, ask what worked, what did not and what you would change. Your final design is never perfect; engineers keep learning.
3. Worked examples
Example 1 (I show you): Define
Cross the stream.
- Problem.
- Criteria.
- Limits.
Answer: Start by defining the problem.
Example 2 (We do it together): Present
Share graph.
- Explain.
- Show.
- Speak clearly.
Answer: Present the evidence.
Example 3 (You try): Reflect
Next time.
Show the steps and answer
- What worked.
- What not.
- Change.
Answer: Reflect to improve.
Did you know?
Real engineering projects, like new airports, can take years and involve thousands of tests.
Why this matters
A project shows that you can use science to solve a real problem.
4. Explore: Final project
Complete the bridge project and present it.
- Define the problem and criteria.
- Design, build and test.
- Improve and record.
- Present and reflect.
Think about it: what did you notice?
What did you notice? Each step helped the next one.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Use every step of the design process | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Work as a team | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Present evidence | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O4 Reflect on what was learned | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
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: “The project is over after the build.” Test, improve, present.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Complete and present a design project.
- 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 completes a design project. You do not need to be an expert to help.
- Listen to the presentation.
- Ask, “What would you change?”
- Celebrate effort.
- 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: use every step of the design process; work as a team; present evidence; reflect on what was learned.
Prerequisite knowledge. Grade 3 science ideas from earlier units: asking questions, fair tests, properties of materials, forces and recording results.
Materials. Card, tape, coins, notebooks, graph paper. 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. Set up presentation space.
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 last week models and ask, “What did we learn?”
Explanation (10 min). Launch the project.
Guided activity (10 min). Teams build and test.
Independent activity (10 min). Teams present.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What worked? What would you change?
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. “The project is over after the build.” Test, improve, present.
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. Complete and present a design project. 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.
