Young Explorers: Discovering Our World · 1st Year

Active learning ideas

The Cycle of Day and Night

First-year students build spatial reasoning when they physically interact with models of Earth’s rotation. Active learning turns abstract concepts like spin and tilt into visible patterns, making routines like sunrise and sunset feel predictable and connected to their lives. This hands-on approach meets their need for concrete evidence while developing early science skills.

Demonstration: Torch and Globe Rotation

Place a lit torch as the sun and a globe as Earth. Shine light on one side to show day, then slowly rotate the globe to demonstrate night on the opposite side. Have students predict shadow positions and take turns rotating while partners observe. Record class predictions versus outcomes on a chart.

Explain the phenomenon of darkness at night.

Facilitation Tip

During the Torch and Globe Rotation, move slowly around the globe so students can line up their own bodies as ‘observers’ to see how light shifts from day to night.

What to look for

Provide students with a drawing of Earth, the Sun, and the Moon. Ask them to draw arrows showing Earth's rotation and label the areas experiencing day and night. Include one sentence explaining why night occurs.

Outdoor Investigation Session: Shadow Length Tracking

Set sticks in the ground at recess start. Mark shadow ends with chalk every 30 minutes until lunch. Students measure lengths with rulers and note changes. Gather to graph results and discuss why shadows shift with the sun's path.

Assess whether the Moon's appearance remains constant.

Facilitation Tip

For Shadow Length Tracking, assign pairs to measure shadows at the same time daily and compare changes to connect length with sun position.

What to look for

Show students several images of the Moon in different phases. Ask them to arrange the images in chronological order and explain one observation about how the Moon's appearance changed from one image to the next.

Class Timeline: Day to Night Journey

Draw a large circle on paper as a clock face. Students add drawings of sun, moon, activities like school or sleep around the edges. Use toy sun and moon to move along the timeline as a group. Discuss predictions for tomorrow's cycle.

Predict the location of the Sun when we are asleep.

Facilitation Tip

In the Class Timeline, invite students to place personal events like lunch or bedtime along a drawn path to show how routines align with Earth’s spin.

What to look for

Pose the question: 'If you were to travel to the Moon, would you see the Sun during your 'night' time there?' Facilitate a discussion using their understanding of rotation and illumination to guide their reasoning.

Journal: Evening Sky Observations

Send home simple journals for families to draw moon shape and note bedtime sky. Next day, students share entries and sort moon drawings by similarity. Connect to class day-night models.

Explain the phenomenon of darkness at night.

Facilitation Tip

During Evening Sky Observations, provide simple star maps and flashlights covered in red cellophane to preserve night vision while recording.

A few notes on teaching this unit

Start with what students already know about their routines, then use physical models to test ideas before discussing evidence. Avoid explaining first; let observations lead the conversation so misconceptions surface naturally. Research shows that drawing connections between personal experience and physical models strengthens spatial understanding in young learners.

By the end of these activities, students will explain that Earth’s spin causes day and night, use observations to track shadows and sky changes, and connect classroom models to their own daily experiences. They will also recognize that light sources and reflectors work differently in space.

Watch Out for These Misconceptions

• During the Torch and Globe Rotation activity, watch for students who say the sun moves or hides at night when the globe turns.

  Use the torch to show that the light stays in one place while the globe spins; ask students to point out where the light lands on the globe as it turns to reinforce that day and night depend on their position, not the sun’s movement.

• During the Torch and Globe Rotation activity, watch for students who say the moon produces its own light and causes night.

  Have students shine the torch on a small reflective surface in the dark to demonstrate how moonlight is reflected sunlight, then relate this to the moon’s role in the night sky during the same activity.

• During Outdoor Shadow Length Tracking, watch for students who say stars only appear because it is dark.

  Ask students to record shadows and note the sky’s color at dawn and dusk; then discuss how sunlight hides stars during the day and why they become visible as Earth turns away from the sun.
