Shadows and the Sun

Active learning works well for this topic because shadows are not just ideas but living observations children make every sunny day. When students move outside, mark shadows, and watch them shift, the sun's motion becomes something they can see and record, making abstract concepts concrete and memorable.

Activity 01

• 30 min · Pairs

Outdoor Tracking: Chalk Shadow Outlines

Take students outside three times: morning, noon, evening. In pairs, they trace each other's shadow with chalk and note approximate length and direction on a chart. Return to class to draw and compare all shadows.

Explain how the position of the sun changes our shadows during the day.

Facilitation Tip

During Outdoor Tracking, have students stand in the same spot each time to avoid confusion from different starting points.

What to look for

Ask students to draw their shadow at three different times: morning, noon, and evening. For each drawing, they should label the time and write one sentence about the shadow's length and direction.

Activity 02

• 45 min · Small Groups

Small Group: Stick Shadow Log

Each small group plants a stick in soft ground or sand. They measure shadow length with a ruler every hour for four sessions, record in a table, and draw a line graph of changes. Discuss patterns as a class.

Compare the length and direction of shadows in the morning, noon, and evening.

Facilitation Tip

For Stick Shadow Log, remind small groups to record both the length and direction of shadows in their notebooks with clear labels.

What to look for

Gather students in a circle and ask: 'Imagine you are standing outside at noon. Where is your shadow? Now imagine it is sunset. Where is your shadow now? What made the shadow change?' Encourage them to use the terms 'sun' and 'shadow'.

Whole Class: Torch Shadow Simulation

Darken the room and use a torch as the 'sun'. Students hold objects at different distances and angles to see shadow length and direction change. Rotate roles and record findings on shared chart paper.

Design an experiment to track your shadow's movement throughout the day.

Facilitation Tip

When running Torch Shadow Simulation, switch off classroom lights to make the torchlight the only light source for accurate observations.

What to look for

Provide students with a worksheet showing a diagram of the sun in three positions (east, overhead, west). Ask them to draw the corresponding shadow for each position and label the direction (e.g., 'points west').

Individual: Shadow Journal

Students pick a sunny day to trace their shadow hourly on paper, measure lengths, and note time and direction. They add drawings and a sentence explaining one change observed.

Explain how the position of the sun changes our shadows during the day.

Facilitation Tip

Ask students to date and time-stamp each entry in their Shadow Journal so they can track changes over days and weeks.

What to look for

Ask students to draw their shadow at three different times: morning, noon, and evening. For each drawing, they should label the time and write one sentence about the shadow's length and direction.

A few notes on teaching this unit

Teachers should begin with real observations because sunlight is immediate and familiar to children. Avoid starting with diagrams or explanations, as hands-on tracking builds intuition first. Research shows that young learners grasp spatial relationships like direction and distance better when they physically mark shadows on the ground. Encourage students to discuss their findings in small groups before sharing with the whole class to build confidence.

Successful learning looks like students confidently predicting shadow direction and length based on the sun's position. They should use words like east, west, overhead, short, and long correctly in their explanations. Children should also notice patterns in their data and share them with peers.

Watch Out for These Misconceptions

• During Stick Shadow Log, watch for students who assume shadows remain the same length all day. Redirect them by asking, ‘Where is the sun at noon compared to morning? How does that affect the shadow on your stick?’ Have them measure and compare the lengths at different times.

  During Stick Shadow Log, students will see shadows shorten and lengthen as the sun moves. Ask them to record the time and length of each shadow. If a student insists shadows stay the same, have them compare their measurements and ask, ‘What changed between 9 AM and 12 PM?’ Use their data to correct the idea together.

• During Torch Shadow Simulation, listen for students saying shadows point towards the sun. Stop the activity and ask, ‘If the torch is the sun, where is the shadow of your hand? Is it on the same side as the torch or opposite?’ Guide them to observe that shadows always point away from the light source.

  During Torch Shadow Simulation, have students change the torch’s angle and observe how the shadow’s direction changes. Ask, ‘If the torch moves to the left, where does the shadow go?’ Use this to reinforce that shadows point opposite the light source.

• During Outdoor Tracking, listen for students who say shadows only form when it is dark. Ask them to look around and notice how their own shadow appears bright and clear in sunlight. Remind them that shadows need light, but the light must be blocked by something, like their body or the stick.

  During Outdoor Tracking, ask students to place different objects in sunlight and observe their shadows. Ask, ‘Is the shadow forming because it is dark or because the object is blocking the sun?’ Use their observations to explain that shadows form when light is blocked, not because of darkness.
