raised to generate
pupils’ curiosity
Lesson Notes
Background: Space has long been a subject of discussion among scientists and astronomers. In particular, the solar system
has been a topic of fascination, with observations and theories made as far back as the second millennium BC. In this chapter,
pupils will learn about the solar system. Pupils will also learn about scientists whose discoveries about the solar system have
profoundly impacted our lives, such as knowing how and why day and night occur, that there are 24 hours in a day and that
the Earth revolves around the Sun and not vice versa.
Chapter opener
Teaching Tip: Tell pupils to imagine that they are sitting on the carousel, and that they are spinning on the ride. Ask pupils to
stand up and spin around to mimic the motion of the turning carousel.
Resources
Textbook page 97
Ask pupils:
 What do you feel after spinning? (Answer: Accept all possible answers.)
 Do you think that the classroom is spinning around you now? (Answer: No.)
 Do you think that our Earth is constantly spinning now? (Answer: Yes.)
Explain that:
 Pupils may feel dizzy because they are spinning around at a fast speed.
 Despite feeling dizzy, the classroom is not spinning around them.
 The Earth is constantly spinning at a very fast speed. Yet, we do not experience any dizziness. Explain to pupils that they
will learn why they do not feel dizzy despite the Earth’s fast spinning speed.
What’s In This Chapter?, What Will I Learn?
Emphasise to pupils what their learning journey will be like for this chapter.
 The solar system consists of eight planets (including Earth) and the Sun.
 The Sun is a star.
 The eight planets move around the Sun, while the Sun remains stationary.

Ask pupils:
 What can you see in the sky? (Answer: The Sun.)
 Why can you see the Sun? (Answer: Because it is bright.)
 Where does the Sun come from? (Answer: Accept all possible answers.)
Then, ask pupils to imagine that it is now at night. Ask pupils:
 What can you see in the sky? (Answer: The moon and stars.)
 Why can you see them? (Answer: Because they are bright.)
 Where do those objects in the sky come from? (Answer: Accept all possible answers.)
 What is the difference between daytime and nighttime? (Answer: Accept all possible answers.)
Explain that:
 The Earth is not the only planet in space. There are also other planets present.
 The Earth is part of the solar system.
Process Skills: Observing, Comparing
21st Century Skill: Communicate clearly
Tell pupils that they will learn what makes up the solar system and how the planets in the solar system revolve around the
Sun.
Activity: Place some planet cutouts in a basket at one end of the classroom. Then, get pupils in groups and instruct them to
run to the basket, retrieve a planet one at a time and bring it back to the starting line. Pupils at the starting line have to
arrange the retrieved planets in the correct order of the solar system. For those who are not familiar with the order of the

Activity: Ask pupils to identify the light sources inside the classroom and in other places such as their homes or in the
shopping malls. Discuss the following questions:
 What is the importance of light in our lives? (Answer: Light allows us to see things around us; it enables plants to make
their own food, etc. Accept all possible answers.)
 Where do sunlight and heat come from? (Answer: The Sun.)
 Why do we experience day and night? (Answer: Accept all possible answers. Tell pupils that they will learn more about
why we experience day and night later in the chapter. )
Explain that:
 The Sun is the Earth’s natural source of light and heat.
 The Sun is the solar system’s star.
Process Skills: Observing, Predicting
21st Century Skill: Think creatively
Explain:
An explanation is
given to clear any
misconceptions
Common Misconception: The Sun is not a solid object. It is a giant ball of gas that continuously releases energy. The Moon
and planets in the solar system do not give out light. They appear bright because they reflect light from the Sun.

Lesson Notes
How Long Does It Take For the Earth to Go Around the Sun?
Background: The Earth and other planets in the solar system revolve around the Sun due to the Sun’s gravity. The Earth takes
a year to complete one revolution around the Sun.
Resources
Textbook page 106
Teaching Tips: You can show an animation on how the Earth and the Moon move.
As an introduction to what Ari said, discuss whether we can live on Venus.
Ask pupils:
 What are the essential elements that we need to survive? (Answer: We need oxygen, water and food to survive —
elements that are absent in Venus. Therefore, we cannot live on Venus.)
 Are there any other life forms in space? (Answer: Accept all possible answers. However, students must understand that
without the essential elements, other life forms cannot survive in space.)
Explain:
An explanation is
given to avoid any
misconception
Common Misconception: Most people tend to think that only the Sun can exert gravity on other planets. That is untrue. In
fact, gravity is a natural pull exerted by objects on each other. Even the Earth exerts a certain amount of gravity on the Sun.
Since the pulling force is proportional to the mass of an object, there is a nett attracting force exerted on the Earth by the Sun.
Activity: Carry out Discover More! And have pupils research on the planet Pluto. Have pupils discuss questions such as why
the International Astronomical Union (IAU) excluded Pluto as the ninth planet from the Sun and not the other eight planets.
URL 6.4
Process Skill: Organising
21st Century Skill: Be self-directed learners
Background: According to the International Astronomical Union (IAU), a planet is only recognised when it meets the following
conditions:
1. The object orbits around the Sun.
2. The object must be a sphere.
3. The object must be able to attract other objects in its orbit.
Pluto fails to meet the third condition and was therefore disqualified from being the ninth planet.

Activity: You may carry out the following experiment to demonstrate how planets travel around the Sun. Tape a string onto a
small ball. Loop and tie the end of the string and place it over a finger. Then, roll the ball away and observe as it moves in a
circular path around the finger. In this activity, the ball represents planet while the string represents gravity. Ask pupils to
think about the relationship between the length of string and the time needed for the ball to complete one revolution. What
will happen if there is no gravity? (Answer: The planets will fly off into space.)
Explain that:
 The Sun’s gravity attracts all other planets towards it.
 The further the distance a planet is from the Sun, the longer time is needed for a planet to complete one revolution
around the Sun.
