Our Solar System (Simplified)Activities & Teaching Strategies
Active learning transforms abstract solar system concepts into tangible experiences. When students build models or role-play orbits, they move beyond memorisation to visualise Earth’s place in space. These hands-on moments make the difference between remembering a fact and understanding a system.
Learning Objectives
- 1Compare Earth to at least two other planets in our solar system based on key characteristics like presence of water, air, and temperature.
- 2Explain why Earth's specific conditions, such as liquid water and a protective atmosphere, are essential for supporting life.
- 3Predict potential challenges for living things on another planet, such as extreme temperatures or lack of breathable air.
- 4Identify the Sun as the central star of our solar system and name at least four planets that orbit it.

Model Building: Solar System Mobile
Provide clay, strings, and coat hangers for students to create planet models scaled by size. Label each planet and hang them around a central Sun. Discuss relative positions as they assemble.
Prepare & details
Compare the Earth to other planets in our solar system.
Facilitation Tip: During Model Building, ask students to calculate the distance between planets using a fixed scale before cutting strings to ensure accuracy.
Setup: Standard classroom — rearrange desks into clusters of 6–8; adaptable to rooms with fixed benches using in-seat group structures
Materials: Printed A4 role cards (one per student), Scenario brief sheet for each group, Decision tracking or event log worksheet, Visible countdown timer, Blackboard or chart paper for recording simulation events
Charting: Planet Comparison Table
Distribute charts listing planets with columns for size, temperature, and life suitability. Students fill in details from class discussion and drawings. Pairs share one unique fact about Earth.
Prepare & details
Explain why the Earth is a good place for living things.
Facilitation Tip: For the Planet Comparison Table, provide a mix of number and picture cards so visual learners match sizes and colours to data.
Setup: Standard classroom — rearrange desks into clusters of 6–8; adaptable to rooms with fixed benches using in-seat group structures
Materials: Printed A4 role cards (one per student), Scenario brief sheet for each group, Decision tracking or event log worksheet, Visible countdown timer, Blackboard or chart paper for recording simulation events
Role-Play: Day on Another Planet
Assign planets to groups; students act out daily life challenges like extreme cold on Mars or heat on Venus using props. Perform for class and note Earth's advantages.
Prepare & details
Predict what it would be like to live on another planet.
Facilitation Tip: In Role-Play, give each group a planet fact sheet so they speak from prepared knowledge rather than improvising unknown details.
Setup: Standard classroom — rearrange desks into clusters of 6–8; adaptable to rooms with fixed benches using in-seat group structures
Materials: Printed A4 role cards (one per student), Scenario brief sheet for each group, Decision tracking or event log worksheet, Visible countdown timer, Blackboard or chart paper for recording simulation events
Observation: Shadow Tracking
Students mark shadows of a stick hourly outside to see Earth's rotation. Record changes and connect to day-night cycle versus other planets.
Prepare & details
Compare the Earth to other planets in our solar system.
Facilitation Tip: When tracking shadows, have students mark positions with chalk every 30 minutes to build a clear timeline of the Sun’s movement.

Teaching This Topic
Teach the solar system as a dynamic system, not a list of facts. Use the Sun’s light as a constant reference point across activities to reinforce its central role. Avoid overloading students with planet names; focus instead on patterns like size or distance from the Sun. Research shows that movement-based activities like shadow tracking and role-play improve spatial reasoning by 20% in primary age groups.
What to Expect
By the end of these activities, students will confidently identify the Sun as the solar system’s centre, list planets in order, and explain why Earth supports life. They will use accurate vocabulary like orbit, rotation, and atmosphere while comparing planet features with evidence from their models and charts.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Model Building, watch for students who place the Sun at the edge of the mobile or move it around the planets.
What to Teach Instead
During the mobile activity, have students hold up their Sun model while others adjust strings so the Sun stays central. Ask the group to observe how Earth’s string moves around the Sun to reinforce orbit concepts.
Common MisconceptionDuring Planet Comparison Table, listen for students who describe all planets as similar in size or texture.
What to Teach Instead
During the table activity, provide actual fruits or balls to represent planet sizes. Ask students to match each fruit to a planet label and note differences in size and colour on the chart.
Common MisconceptionDuring Role-Play, watch for students who position the Moon as a separate entity orbiting the Sun instead of Earth.
What to Teach Instead
During role-play, have each group hold hands to form Earth while one student acts as the Moon orbiting Earth. Use a fixed Sun position in the room to show the Earth-Moon-Sun system clearly.
Assessment Ideas
After Charting Planet Comparison Table, show students pictures of Earth and two other planets. Ask them to point to Earth and state one unique feature from their table, then name the Sun and one planet that orbits it.
During Role-Play, pause the activity and ask each group to explain why their chosen planet would be hard to live on and what supplies they would bring. Listen for use of vocabulary like atmosphere, temperature, or water.
After Shadow Tracking, give students a card to draw Earth and label two features that make it a good home. Then ask them to write the name of the star at the centre of our solar system.
Extensions & Scaffolding
- Challenge early finishers to calculate the time it would take to travel from Earth to Jupiter at 100 km/h and compare this to the fastest spacecraft speed.
- Scaffolding for struggling students: Provide pre-cut planet shapes and labelled stickers so they focus on comparison rather than cutting or writing.
- Deeper exploration: Ask students to research why Pluto is no longer called a planet and present findings in a mini debate using their model as a visual aid.
Key Vocabulary
| Solar System | The Sun and all the celestial bodies that orbit around it, including planets, moons, and asteroids. |
| Planet | A large, round celestial body that orbits a star, like our Sun. Planets do not produce their own light. |
| Orbit | The curved path that a planet or moon takes as it travels around another celestial body. |
| Atmosphere | The layer of gases surrounding a planet, like the air we breathe on Earth. |
Suggested Methodologies
Planning templates for Science (EVS K-5)
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
