Day and Night

Hands-on activities help Class 2 students grasp how Earth’s rotation creates day and night. Observing shadows, moving models, and sorting pictures make abstract ideas concrete and memorable for young learners.

• CBSE Learning Outcomes
• NCERT EVS Syllabus Class I-II, Theme: Water - Differentiates between day and night.
• CBSE EVS Syllabus Class II: Understands the concept of the day and night cycle and relates it to the presence of the sun.
• NCERT Learning Outcomes at Elementary Stage: EVS-202 - Associates activities with day and night.

Activity 01

• Hot Seat
• 30 min · Whole Class

Demonstration: Globe and Torch Model

Use a globe or ball as Earth and a torch as the Sun. Rotate the globe slowly while students observe lit and dark sides. Have them call out 'day' or 'night' and note shadow changes. Discuss how rotation creates cycles.

Explain why we experience day and night.

Facilitation Tip

During the Globe and Torch Model, rotate the globe slowly so students see how one side lights up while the other stays dark.

What to look for

Show students a picture of the Earth with one side lit by the Sun. Ask: 'Is this side experiencing day or night? What is happening on the other side?' Observe their responses to gauge understanding of the basic concept.

Activity 02

• Outdoor Investigation Session
• 45 min · Small Groups

Outdoor Investigation Session: Shadow Stick Tracking

Place sticks in the ground at different times. Mark shadow lengths and directions on paper. Compare morning, noon, and afternoon shadows in small groups. Link changes to Earth's turn.

Analyze the activities we do during the day versus at night.

Facilitation Tip

For Shadow Stick Tracking, mark the shadow’s position at the same time each day to show the Sun’s apparent movement.

What to look for

Pose the question: 'Imagine if it was always daytime. What are three things that would be different?' Encourage students to share their ideas about sleep, plants, and animals, assessing their predictive thinking.

Activity 03

• Hot Seat
• 25 min · Pairs

Pairs: Day-Night Activity Sort

Provide cards with pictures like 'brush teeth' or 'play cricket'. Pairs sort into day or night piles and explain choices. Share with class and predict routine changes if always day.

Predict what would happen if it was always day or always night.

Facilitation Tip

In the Day-Night Activity Sort, ask pairs to explain their choices aloud to reinforce vocabulary and reasoning.

What to look for

Give each student a slip of paper. Ask them to draw one activity they do during the day and one activity they do at night. This helps assess their ability to differentiate between day and night routines.

Activity 04

Individual: What If Drawings

Students draw and label what happens if always day or night, showing effects on sleep, plants, animals. Share drawings in a class gallery walk for peer feedback.

Explain why we experience day and night.

Facilitation Tip

While students draw What If Drawings, remind them to label day and night activities clearly to show understanding.

What to look for

Show students a picture of the Earth with one side lit by the Sun. Ask: 'Is this side experiencing day or night? What is happening on the other side?' Observe their responses to gauge understanding of the basic concept.

A few notes on teaching this unit

Start with the globe-torch demonstration to introduce the concept visually. Follow with outdoor shadow tracking to connect daily routines to the Sun’s position. Avoid lengthy explanations; instead, let students observe, discuss, and correct each other’s ideas. Research shows that young children learn spatial concepts best through movement and concrete materials rather than abstract talks.

By the end of these activities, students will explain why day and night occur, compare their routines during each, and correct common misconceptions using evidence from the globe-torch model and shadow tracking.

Watch Out for These Misconceptions

• During the Globe and Torch Model, watch for students who say the torch moves around the globe to make day and night.

  Hold the torch steady and rotate the globe to show that Earth’s movement causes day and night, not the Sun’s movement. Ask, 'What do you see happening to the light as I turn the globe?' to guide their observation.

• During Shadow Stick Tracking, watch for students who think the Sun hides behind mountains at sunset.

  Use the shadow stick and ask, 'Where is the Sun now compared to where it was earlier?' to show that the Sun’s position changes because Earth rotates, not because it hides.

• During the Day-Night Activity Sort, watch for students who sort activities like 'eating lunch' in both day and night piles.

  Ask pairs to justify their choices by linking activities to daylight or darkness. For example, 'Is lunch usually eaten when it’s light outside? Why?' to guide their reasoning.
