Learning objective
• Recognise what we can see in the sky during the day and at night.
Option 1
Purpose: To assess pupils' prior knowledge of the things they notice in the sky
Resources: Textbook, books with pictures of the day and night sky
1. You may wish to bring a selection of books that have day scenes and night scenes. Ask pupils to sit in groups
to browse through the books. Have them focus on what they can see in the sky. Ask for volunteers to tell the
class one object they can see in the sky during the day, and one object they can see in the sky at night. List
pupils' answers in a table on the board.
Option 2
Purpose: To assess pupils' prior knowledge of the things they see in the sky
Resources: Pictures of the Sun, Moon and stars
1. Show pupils pictures of the Sun, Moon and stars. Point to them and ask:
• What are these? (The Sun, Moon and stars.)
• Can you seethe Sun, Moon and stars all the time? Why or why not? (We do not see the Sun, Moon and
stars all the time. We can only see the Sun in the sky during the day, and the Moon and the stars at night.
Sometimes, we can see the Moon during the early morning or evening hours.)
2. Have pupils turn to Textbook pp. 18—19. Ask:
• Which picture shows daytime? (The picture on top shows daytime.)
• Why do you say so? (The sky is blue.)
• Which picture shows nighttime? (The picture below shows nighttime.)
• Why do you say so? (The moon and stars are in the sky. The sky is black/dark.)
Direct pupils to the question at the bottom of Textbook p. 18. Ask for volunteers to share the things they can
see in the sky during the day and at night.
Purpose: To identify the things we can see in the sky during the day and at night
Resource: Textbook
1. Have pupils turn to Textbook pp. 20—21. Direct pupils to the trigger questions. Point to the words in the
'Word bank' and guide pupils to use the words to answer the questions. Discuss possible answers.
2. Have pupils identify the things they see in the sky, e.g. the Sun, clouds, aeroplane, birds.
3. Guide pupils to understand that it is bright during the day because the Sun is shining in the sky. Ask:
• Why are some of the children wearing caps? (The caps provide shade from the bright sunlight)
4. Direct pupils to the 'Be careful' feature on Textbook p. 21. Warn pupils of the danger of staring directly at
the Sun.
5. Direct pupils to the 'Explore' activity on Textbook p. 21. Ask for volunteers to share what we can do during
the day.
6. Have pupils turn to Textbook pp. 22—23. Direct pupils to the trigger questions. Point to the words in the
'Word bank' and guide pupils to use the words to answer the questions. Discuss possible answers.
7. Have pupils identify the things they see in the sky, e.g. the Moon, stars, clouds.
8. Guide pupils to understand that it is dark at night because we cannot see the Sun shining in the sky. Direct
pupils to look at Dr Atom and Joe. Ask:
• Why are Dr Atom and Joe each holding a torch? (It is dark at night. They need a torch to help them
see better.}
9. Tell pupils that Sue is looking through a telescope and a telescope is used to look at things that are far away.
Ask:
• What is Sue looking at? (She is looking at the Moon and the stars.)
10. Direct pupils to the 'Science at home' activity on Textbook p. 23. Have volunteers share their artwork of the
night sky.
Purpose: To understand the differences between the sky during the day and at night
Resource: Textbook
1. Have pupils turn to Textbook pp. 24—25. Consolidate the points discussed earlier. Guide pupils to see the
main differences between the sky during the day and at night. E.g. The sky is blue during the day, but black/
dark at night; We can see the Sun in the sky during the day, but we cannot see the Sun in the sky at night.
1. Bring pupils out of the class. Ask them to observe the sky. Remind pupils to shield their eyes with their hands
if it is too bright. They also should not look directly at the sun.
2. Ask for volunteers to share what they can see in the sky.
3. Have pupils complete Activities 9.1 and 9.2 on Activity Book pp. 6—9. Pupils may work independently or in
pairs. Guide pupils to fill in their best possible answers. Ask pupils to share their answers. Correct or refine
their answers.
1. Revisit the learning objective of this unit. Have pupils turn to Textbook pp. 18—19. Ask them to point out the
differences between the sky during the day and at night.
2. Direct pupils to the pictorial concept map on Textbook pp. 26—27. Sum up that we can see different things in
the sky during the day and at night.
3. Go through the'Science words' list with pupils. Ask pupils if there is any word they are not sure of and explain
it to them. Encourage pupils to learn how to spell these words and to form sentences with each word. E.g.
The sky is bright during the day; We can see clouds in the sky; We can see the Moon in the sky at night.
4. Have pupils complete the 'Self-check' activity independently or in pairs. Guide pupils to complete the
questions if there is a need to. Check that pupils' answers are correct.

Backgroun
We experience the day and night cycle due to the rotation of the Earth on its axis. It takes the Earth 24 hours
to complete one full rotation. Each half of the earth experiences approximately 12 hours of daylight. The half
that faces the Sun experiences day and the opposite half which is not facing the Sun experiences night.
The temperature is generally higher during the day because of the Sun. At night, when tneSun has set, our
surroundings cool down and we usually do not feel as warm.

informati
The Moon does not give out its own light. It reflects light from the Sun. During the day, the Moon is not visible
as the Sun is the brightest object in the sky. However, early in the morning, the Moon may still be visible for a
short period of time.
There are millions of stars in the sky. However, we are not always able to see many stars in the night sky
because our surroundings are too bright. The night sky in the countryside will be brighter with stars because
there is little or no light from streetlamps or high-rise buildings. We can also see planets, such as Mars or
Venus, and other satellites in the night sky. One way to distinguish stars from planets and satellites is to
observe how they shine. Stars twinkle but planets and satellites give a continuous glow.
