Activity 01
Globe Rotation Model: Day-Night Simulation
Supply each small group with a globe, torch as Sun, and sticky note for Ireland. Rotate the globe eastward slowly while observing the location's light exposure. Record times when it enters day and night, then draw the Sun's sky path. Discuss observations as a class.
Explain how the Earth's rotation creates the cycle of day and night.
Facilitation TipDuring the Globe Rotation Model, have students mark their exact location on the globe with a sticker so they can track its movement into and out of the torch’s light.
What to look forProvide students with a simple diagram of the Earth, Sun, and a flashlight. Ask them to draw arrows showing the direction of Earth's rotation and label the areas experiencing day and night. Ask: 'What causes the change from day to night?'

Activity 02
Shadow Tracking: Outdoor Timelapse
Pairs place metre sticks vertically outside at 10am, noon, and 2pm. Measure and photograph shadows, noting length and direction. Back inside, plot data on graphs and explain links to Sun position and Earth's turn. Compare with weather records.
Compare the appearance of the Sun in the sky at different times of day.
Facilitation TipFor Shadow Tracking, remind students to check shadows at the same time each day to build a consistent data set.
What to look forPose the question: 'Imagine Earth stopped spinning. What would happen to the side facing the Sun all the time, and what would happen to the side facing away?' Facilitate a class discussion, guiding students to use their understanding of rotation and light to justify their predictions.

No Rotation Predictions: Scenario Cards
Distribute cards describing a non-rotating Earth. In pairs, students predict daily temperatures, plant growth, and animal behaviour on each side. Groups share via jigsaw, using models to test ideas and refine with evidence.
Predict what would happen to the Earth's temperature if it stopped rotating.
Facilitation TipWhen using No Rotation Predictions, ask students to justify their answers with evidence from their globe models before revealing the correct scenario.
What to look forStudents draw a quick sketch of the Sun's apparent path across the sky from morning to evening. Below their sketch, they write one sentence explaining why the Sun appears to move.

Activity 04
Sun Path Mural: Whole Class Timeline
Create a large mural of the sky. Whole class adds Sun positions, shadow sketches, and times from personal observations. Rotate a model Earth nearby to verify placements, then label day/night zones.
Explain how the Earth's rotation creates the cycle of day and night.
Facilitation TipDuring the Sun Path Mural, encourage students to draw the Sun’s position at key times and label the corresponding shadows they observed outdoors.
What to look forProvide students with a simple diagram of the Earth, Sun, and a flashlight. Ask them to draw arrows showing the direction of Earth's rotation and label the areas experiencing day and night. Ask: 'What causes the change from day to night?'

Teaching this topic works best when students build their own models first, then test their ideas against observations. Avoid starting with explanations—let students discover the cause through guided exploration. Research shows that kinesthetic activities like holding a globe and moving it under a torch create stronger mental models than passive diagrams. Focus on helping students articulate the difference between rotation and orbit to address common misconceptions directly.
Students will confidently explain that Earth’s rotation causes day and night and will use evidence from their models and observations to support this idea. They will connect their location’s movement to the Sun’s apparent path across the sky and recognize that rotation, not orbit or blocking, drives the cycle. Look for clear language and accurate diagrams in their work.
Watch Out for These Misconceptions
During the Globe Rotation Model, watch for students who describe the Sun as moving around Earth. Redirect them by having them physically rotate the globe and observe their marked location moving into and out of the torch’s light, then ask them to explain what they see happening from Earth’s perspective.
Ask students to trace the path of their sticker on the globe as it moves into and out of the torch’s beam. Have them describe the Sun’s position relative to their location in their own words, emphasizing that their movement creates the illusion of the Sun’s motion.
During the Shadow Tracking activity, watch for students who connect daily shadow changes to Earth’s orbit around the Sun. Redirect by having them compare shadow lengths and directions over several days while emphasizing that these changes happen within a single day, not over months.
After collecting data, ask students to note the time of day for each shadow measurement. Guide them to recognize that shadows change predictably within a 24-hour period, then ask them to explain why this pattern repeats daily rather than yearly.
During the Sun Path Mural, watch for students who attribute night to clouds or mountains blocking the Sun. Redirect by asking them to observe the mural and consider what is happening on the half of Earth facing away from the Sun, then compare their mural to their outdoor shadow observations.
Have students add a label to their mural showing the Earth’s rotation and the Sun’s position. Ask them to explain why the side of Earth facing away from the Sun experiences darkness, even on clear nights, using their globe model as evidence.
