to judge how well something works
a balance between competing needs
1. Discover: The school challenge
Class 5 chooses a challenge: keep a seedling watered while the school is closed for a weekend. Teams define the problem, research, sketch, build, test and improve a self-watering planter from reused bottles, then present their results.
Think: How will the team show their design is sustainable?
2. Understand: Project
Idea 1: Plan
Choose a real problem, write a statement with criteria and constraints, and plan the time you have.
Idea 2: Do
Research, sketch three ideas, choose with a table, build, test three times and improve with one change at a time.
Idea 3: Share
Present the problem, the design, the test evidence, the improvements and the sustainability benefits. Listen to feedback.
3. Worked examples
Example 1 (I show you): Plan
Project.
- Problem.
- Criteria.
- Constraints.
Answer: A clear brief.
Example 2 (We do it together): Evaluate
Results.
- Data.
- Criteria.
- Improve.
Answer: Judge with evidence.
Example 3 (You try): Present

Show the steps and answer
- Problem.
- Design.
- Evidence.
Answer: A clear talk.
Did you know?
Real engineering projects, such as bridges, take teams of many people and years of testing.
Why this matters
Projects show that science and engineering can solve real problems.
4. Explore: Self-watering planter
Make a planter from a clean, reused bottle and a cotton strip that waters a seedling, test how long it stays moist, improve it and present it.
- Define the problem.
- Build the planter.
- Test and improve.
- Present the results.
Think about it: what did you notice?
What did you notice? The wick length changed the watering speed.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Apply every step | 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 Justify decisions with 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 |
| O3 Include sustainability | 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 Present a solution | 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: “Presenting is optional.” Sharing helps.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Complete and present an engineering 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 an engineering project. You do not need to be an expert to help.
- Help gather bottles.
- 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: apply every step; justify decisions with evidence; include sustainability; present a solution.
Prerequisite knowledge. Grade 4 ideas: testing fairly, improving a design and using simple technology.
Materials. Clean bottles, cotton strip, soil, seedling. 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. Clean bottles; adult cuts.
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 wilting plant and ask, “How could we keep it watered?”
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 did the evidence show? How is it sustainable?
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. “Presenting is optional.” Sharing helps.
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 an engineering 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.
