Earth's Place in the Solar SystemActivities & Teaching Strategies
Active learning lets students see Earth’s position in space through their senses and movement, making abstract cycles like day and night feel real. By manipulating models and tracking shadows, they connect personal observation to scientific ideas about rotation, orbit, and scale.
Learning Objectives
- 1Identify the Sun as the center of our solar system and Earth as one of its planets.
- 2Describe the apparent movement of the Sun across the sky during a day.
- 3Compare the length of daylight and nighttime in different seasons.
- 4Demonstrate how Earth's rotation causes day and night using a model.
- 5Explain that Earth orbits the Sun over a year, influencing seasons.

Outdoor Shadow Hunt: Tracking Changes
Mark student positions with chalk at recess, trace shadows hourly using sticks. Students measure and compare lengths with rulers, draw paths on paper. Discuss patterns as a group, noting how shadows shorten at midday.
Prepare & details
Describe the relative sizes and distances of planets in our solar system.
Facilitation Tip: During the Outdoor Shadow Hunt, move the hunt to different times of day to show students how shadows shift direction and length.
Setup: Open space or rearranged desks for scenario staging
Materials: Character cards with backstory and goals, Scenario briefing sheet
Globe and Torch: Day Night Model
Use a globe and bright torch as Sun. Pairs spin the globe slowly, observe lit and dark sides. Tilt it to show longer summer days, record observations in simple drawings.
Prepare & details
Explain the concept of gravity and its role in maintaining planetary orbits.
Facilitation Tip: While using the Globe and Torch, dim the lights to make the torch’s light more dramatic and highlight the lit half of the globe.
Setup: Open space or rearranged desks for scenario staging
Materials: Character cards with backstory and goals, Scenario briefing sheet
Playdough Planets: Size Sort
Provide playdough in colours for Sun and planets. Students roll balls to match relative sizes, from huge Sun to tiny Earth. Line up on paper orbit paths, label distances with string.
Prepare & details
Analyze how Earth's tilt and orbit around the Sun influence phenomena like seasons and day length.
Facilitation Tip: When making Playdough Planets, provide a reference object (like a marble for Earth) to anchor size comparisons before modeling.
Setup: Open space or rearranged desks for scenario staging
Materials: Character cards with backstory and goals, Scenario briefing sheet
Spinner Earth: Rotation Demo
Make paper plate Earth spinners with pencils. Students twirl to mimic spin, use fan as wind for day night effects. Predict shadow positions, test with partners.
Prepare & details
Describe the relative sizes and distances of planets in our solar system.
Facilitation Tip: With the Spinner Earth, pre-poke the hole for the skewer so students focus on tilting and spinning rather than setup.
Setup: Open space or rearranged desks for scenario staging
Materials: Character cards with backstory and goals, Scenario briefing sheet
Teaching This Topic
Teachers use physical models to confront misconceptions directly, letting students test ideas through trial and error. Avoid over-explaining; instead, pose questions that guide discovery. Research shows hands-on modeling and repeated observation build lasting understanding of Earth’s movement and scale.
What to Expect
Students will explain how Earth’s spin creates day and night, compare planetary sizes, and describe seasonal changes using models and observations. They will use accurate vocabulary like ‘axis,’ ‘orbit,’ and ‘tilt’ in discussions and drawings.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Globe and Torch, watch for students who say the Sun moves around Earth to make day and night.
What to Teach Instead
Ask them to slowly spin the globe while keeping the torch fixed, then point to the side facing the torch and label it ‘day.’ Have peers confirm by watching which side gets light as the globe turns.
Common MisconceptionDuring Playdough Planets, watch for students who roll equally sized balls for all planets or include the Sun as one of the planets.
What to Teach Instead
Display a real image of the Sun and planets, then have students reshape their playdough, comparing each piece to the reference sizes. Ask them to set the Sun aside as much larger before sorting the rest.
Common MisconceptionDuring Spinner Earth, watch for students who say seasons happen because Earth gets closer to the Sun in summer.
What to Teach Instead
Have them tilt the axis while spinning and notice how one hemisphere leans toward the light while the other leans away. Ask them to describe how the tilted side gets more direct sunlight, changing temperatures.
Assessment Ideas
After the Outdoor Shadow Hunt, ask students to draw a picture showing the Sun, a stick they observed, and two shadows taken at different times. Label the shadows ‘morning’ and ‘afternoon’ and draw arrows showing the Sun’s position in the sky.
During the Globe and Torch activity, show the globe and torch and ask: ‘What does the torch represent? What does the spinning globe show happening on Earth?’ Listen for explanations that include rotation and the lit half facing the light.
After the Spinner Earth activity, give students the sentence starter: ‘Earth’s tilt and orbit cause…’ Ask them to complete it and draw a small picture showing the tilted Earth orbiting the Sun with sunlight hitting different parts.
Extensions & Scaffolding
- Challenge: Ask early finishers to time their shadows every hour and graph the changes to predict the next day’s pattern.
- Scaffolding: Provide a labeled diagram of Earth and Sun for students to reference as they build their playdough models.
- Deeper exploration: Use a lamp and a tilted globe to model how sunlight spreads differently in summer and winter, linking to temperature changes.
Key Vocabulary
| Sun | The star at the center of our solar system that provides light and heat to Earth. |
| Earth | The planet we live on, which spins and moves around the Sun. |
| Orbit | The curved path an object takes as it moves around another object in space, like Earth moving around the Sun. |
| Rotation | The spinning of Earth on its axis, which causes day and night. |
| Season | One of the four periods of the year (spring, summer, autumn, winter) caused by Earth's tilt and its orbit around the Sun. |
Suggested Methodologies
Planning templates for Science
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.
