Activity 01
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.
Explain why we have light during the day and darkness at night.
Facilitation TipDuring Shadow Measuring, ask students to stand on the same spot every 30 minutes so they see how shadow length and direction change over time.
What to look forGive each student a card with a drawing of the Sun. Ask them to draw one thing that happens during the day because of the Sun and one thing that happens at night. They should also write one sentence about why the Sun is important.

Activity 02
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.
Predict what would happen to Earth if the sun disappeared.
Facilitation TipWhen demonstrating Day and Night Rotation, turn the globe slowly while a torch shines on it, so students notice how light moves across the surface.
What to look forAsk students to stand up and point in the direction of the Sun (if visible). Then, ask them to imagine it is nighttime and point in the opposite direction. This helps check their understanding of Earth's rotation relative to the Sun.

Activity 03
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.
Analyze how the sun's heat affects our daily lives.
Facilitation TipIn the Sensing Station, give students two identical thermometers—one in sunlight, one in shade—to measure temperature differences in real time.
What to look forPose the question: 'What would happen to our school if the Sun suddenly disappeared?' Encourage students to share their ideas about light, heat, and plant growth. Record their predictions on the board.

Activity 04
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.
Explain why we have light during the day and darkness at night.
Facilitation TipFor the Prediction Game, pause after each scenario and ask students to explain their answers using evidence from previous activities.
What to look forGive each student a card with a drawing of the Sun. Ask them to draw one thing that happens during the day because of the Sun and one thing that happens at night. They should also write one sentence about why the Sun is important.

Generate Complete Lesson→A few notes on teaching this unit
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.
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.
Watch Out for These Misconceptions
During Shadow Measuring, watch for students who say the Sun moves to create shadows.
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.
During Model Demo: Day and Night Rotation, listen for students who attribute day and night to the Sun moving around Earth.
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.
During Sensing Station: Heat from Sun, note if students believe the Sun only provides heat at midday.
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.
