Student lesson
- Sputnik was launched in 1957.
- Apollo 11 landed humans on the Moon in 1969.
- Rockets work by action and reaction.
- Probes and rovers explore without people.
Words to know
an object that orbits a larger body
an uncrewed spacecraft that explores
a vehicle that travels on a planet’s surface
the force that pushes a rocket forward
1. Discover: The mission patch
Ms Boateng asks each group to design a mission patch for a mission to Mars. “What would your crew need to survive?” she asks. The groups list air, water, food, warmth and communication.
Think: Which need is hardest to solve on a long trip?
2. Understand: Exploring space
Idea 1: Milestones
Sputnik 1 (1957) was the first satellite. Yuri Gagarin was the first human in space (1961). Apollo 11 put people on the Moon (1969). Since then we have built space stations, sent probes to every planet, and landed rovers on Mars.
Idea 2: How rockets work
A rocket pushes hot gas down and the gas pushes the rocket up: Newton’s action and reaction. This thrust must be greater than the rocket’s weight to lift off.
Idea 3: Why explore
We explore to learn how the Solar System formed, search for life, use satellites for weather and navigation, test new technology and inspire people. Challenges include cost, radiation, long travel times and keeping crews healthy.
3. Worked examples
Example 1 (I show you): Order
Milestones.
- Sputnik.
- Gagarin.
- Apollo 11.
Answer: 1957, 1961, 1969.
Example 2 (We do it together): Explain
Thrust.
- Gas down.
- Rocket up.
- Reaction.
Answer: Action and reaction.
Example 3 (You try): Evaluate
Challenges.
Show the steps and answer
- Cost.
- Radiation.
- Distance.
Answer: Trade-offs.
Did you know?
A signal from Mars takes between 3 and 22 minutes to reach Earth, so rovers must make many decisions on their own.
Why this matters
Space technology gives us weather forecasts, GPS and many everyday inventions.
4. Explore: Mission design
On paper, design a Mars mission: list needs of the crew, choose a landing site, draw a rover and explain one risk and how you would reduce it.
- List needs.
- Choose a site.
- Draw the rover.
- Explain a risk.
Think about it: what did you notice?
What did you notice? Each solution brought new trade-offs.

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: “Rockets push against the air.” Gas reaction.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Evaluate space exploration.
- 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 studies space exploration. You do not need to be an expert to help.
- Watch a mission video.
- Ask “Why go?”
- Never launch homemade rockets.
- 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: summarise milestones; explain why we explore; explain rockets simply; evaluate challenges.
Prerequisite knowledge. Grade 5 ideas: the Solar System, the Sun, Earth and Moon motions and models.
Materials. Paper, pens, library books. 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 out resources.
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 Mars rover photo and ask, “How did it get there?”
Explanation (10 min). Teach exploration.
Guided activity (10 min). Learners design.
Independent activity (10 min). Learners present.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Why explore? How do rockets work?
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. “Rockets push against the air.” Gas reaction.
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. Evaluate space exploration. 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.
