The Sun: Our Source of Light and HeatActivities & Teaching Strategies
Active learning works for this topic because young students learn best by seeing, touching, and moving. When they trace their own shadows or feel the warmth of sunlight, abstract ideas about Earth's rotation and heat become clear through direct experience.
Learning Objectives
- 1Identify the Sun as the primary source of light and heat for Earth.
- 2Explain the relationship between the Sun's position and the occurrence of day and night.
- 3Analyze how the Sun's heat influences daily activities and the environment.
- 4Predict the immediate effects on Earth if the Sun were to disappear.

Outdoor Activity: Shadow Measuring
Students choose a stick or themselves as a shadow caster. Mark shadow ends at three times: morning, noon, afternoon. Measure and draw changes on chart paper, then discuss patterns in class.
Prepare & details
Explain why we have light during the day and darkness at night.
Facilitation Tip: During Shadow Measuring, ask students to stand on the same spot every 30 minutes so they see how shadow length and direction change over time.
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
Model Demo: Day and Night Rotation
Use a torch as Sun and a ball or globe as Earth. Shine light on one side while rotating the ball slowly. Students observe lit and dark halves, noting how rotation brings day and night.
Prepare & details
Predict what would happen to Earth if the sun disappeared.
Facilitation Tip: When demonstrating Day and Night Rotation, turn the globe slowly while a torch shines on it, so students notice how light moves across the surface.
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
Sensing Station: Heat from Sun
Set stations with thermometers: one in direct sun, one in shade. Students record temperatures after 10 minutes. Feel black paper in both spots and compare results.
Prepare & details
Analyze how the sun's heat affects our daily lives.
Facilitation Tip: In the Sensing Station, give students two identical thermometers—one in sunlight, one in shade—to measure temperature differences in real time.
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
Prediction Game: No Sun Scenario
In groups, list daily activities needing sun. Predict changes without it, like no warmth or plants dying. Share and vote on class predictions.
Prepare & details
Explain why we have light during the day and darkness at night.
Facilitation Tip: For the Prediction Game, pause after each scenario and ask students to explain their answers using evidence from previous activities.

Teaching This Topic
Experienced teachers approach this topic by starting with children’s lived experiences—playing in sunlight, noticing long evening shadows, or feeling warmth on their skin. We avoid abstract explanations first; instead, we guide students to observe patterns, collect evidence, and verbalise their findings. Research shows that using real objects like globes, thermometers, and tracing paper helps children build accurate mental models faster than diagrams alone.
What to Expect
Successful learning looks like children confidently explaining why shadows shrink at midday or why it feels cooler in shade. They should connect sunlight to heat, link Earth’s spin to day and night, and use accurate terms like rotation and shadow without prompting.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Shadow Measuring, watch for students who say the Sun moves to create shadows.
What to Teach Instead
Remind students to keep their feet in the same spot and observe how the shadow changes direction relative to their body, reinforcing that the Sun’s position changes due to Earth’s rotation.
Common MisconceptionDuring Model Demo: Day and Night Rotation, listen for students who attribute day and night to the Sun moving around Earth.
What to Teach Instead
Turn the globe slowly while shining a torch on it, then ask students to explain what is moving—Earth or the Sun—and record their observations on the board.
Common MisconceptionDuring Sensing Station: Heat from Sun, note if students believe the Sun only provides heat at midday.
What to Teach Instead
Ask students to compare the thermometer readings in sunlight at different times and discuss why shadows are shorter at noon but heat is still felt in the afternoon.
Assessment Ideas
After Shadow Measuring, give each student a card with a Sun drawing and ask them to draw one thing that happens because of the Sun during the day and one thing at night. Ask them to write one sentence about why the Sun is important.
During Model Demo: Day and Night Rotation, ask students to point in the direction of the Sun (if visible) and then point in the opposite direction to represent nighttime. Listen for explanations about Earth’s rotation.
After the Prediction Game, ask: 'What would happen to our school if the Sun suddenly disappeared?' Record their ideas about light, heat, and plant growth on the board to assess their understanding of the Sun’s role.
Extensions & Scaffolding
- Challenge students to predict and measure shadow lengths at 7 AM, 11 AM, and 3 PM, then compare predictions with measurements.
- For students who struggle, pair them with a peer to trace shadows together and discuss why shadows appear in one place.
- Deeper exploration: Have students research how different cultures used sundials and present their findings to the class.
Key Vocabulary
| Sun | A star at the center of our solar system that provides light and heat to Earth. |
| Light | Energy that makes things visible, coming from the Sun during the day. |
| Heat | Energy that makes things warm, felt from the Sun's rays. |
| Day | The period of time when it is light outside because the Sun is shining on our part of Earth. |
| Night | The period of time when it is dark outside because our part of Earth is facing away from the Sun. |
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.
