Activity 01
Outdoor Shadow Tracking: Stick Method
Place sticks in the ground at sunrise, midday, and sunset. Students measure and record shadow lengths and directions with rulers and compasses. Groups sketch changes on worksheets and discuss patterns at the end.
Explain why the sun appears to move across the sky each day.
Facilitation TipDuring Outdoor Shadow Tracking, place sticks in soft ground to avoid leaning, and mark shadows with washable chalk for clear comparisons.
What to look forProvide students with a simple diagram of a house. Ask them to draw the sun in the morning (e.g., east) and in the afternoon (e.g., west), and draw the shadow cast by the house in each position. Ask: 'Where does the sun appear to be at lunchtime?'

Activity 02
Classroom Model: Torch and Globe
Use a globe as Earth and a torch as the sun. Rotate the globe slowly while marking observer positions. Students predict and draw the sun's path on paper, then verify with the model.
Compare the sun's position in the morning to its position in the afternoon.
Facilitation TipIn the Classroom Model activity, dim the lights to highlight the torch’s light and reduce distractions from other classroom lights.
What to look forAsk students: 'Imagine you are playing outside at 9 AM and again at 3 PM. How would the sun's position in the sky be different? How would your shadow be different?' Encourage them to use vocabulary like 'sunrise', 'sunset', and 'apparent movement'.

Activity 03
Sunrise Sunset Chart: Whole Class Data
Assign students to record local sunrise and sunset times daily for a week using reliable apps or calendars. Plot on a class chart and compare morning to afternoon positions.
Predict where the sun will rise and set.
Facilitation TipFor the Sunrise Sunset Chart, assign small groups to record data at consistent times each week to build reliable patterns.
What to look forObserve students during outdoor shadow tracking. Ask individual students to point to where the sun is and where their shadow is pointing at different times of the day. Ask: 'What do you think will happen to your shadow in one hour?'

Activity 04
Prediction Walk: Schoolyard Path
Walk the school grounds at different times, noting sun position relative to landmarks. Predict next-day positions and test observations the following day.
Explain why the sun appears to move across the sky each day.
Facilitation TipOn the Prediction Walk, pause at key points to ask students to point out the sun’s direction and compare it to their shadow’s position.
What to look forProvide students with a simple diagram of a house. Ask them to draw the sun in the morning (e.g., east) and in the afternoon (e.g., west), and draw the shadow cast by the house in each position. Ask: 'Where does the sun appear to be at lunchtime?'

Start with hands-on work before abstract explanations. Young learners benefit from physical models and repeated observations to build accurate mental models. Avoid lectures about rotation—let the evidence from shadows and models speak first. Research shows that guided inquiry, where teachers scaffold but do not give answers, leads to deeper understanding and retention of Earth’s movements.
By the end of these activities, students will confidently explain that Earth’s rotation causes the sun’s apparent movement, predict shadow directions, and use data to track daily changes. Mistakes become learning moments as they test and refine their ideas.
Watch Out for These Misconceptions
During Outdoor Shadow Tracking, watch for students who say the sun moves because it is following them or because it ‘wants’ to shine on them.
Use the shadow stick and torch model from Classroom Model to demonstrate that the sun’s light stays in a straight line; Earth’s rotation makes it appear to move. Have students rotate the globe while keeping the torch fixed to show the ‘sun’ moving across the sky.
During Outdoor Shadow Tracking, watch for students who assume shadows always point north because of magnetic compass directions.
Ask students to compare their shadow directions to the sun’s position in the sky during Outdoor Shadow Tracking. Use the stick and chalk to mark both the shadow and the sun’s location, then discuss that shadows point opposite the sun’s direction.
During Sunrise Sunset Chart, watch for students who record the same sunrise and sunset positions every day without noticing slight shifts.
After collecting two weeks of data, gather students to compare their Sunrise Sunset Chart. Point out subtle changes and connect them to Earth’s orbit using the globe and torch model to show why the sun’s rising and setting points shift very slightly over time.
