LESSON 1
Look at the pictures below.
How many different kinds of movements can you identify?
Complete the list.

• Living things move by themselves.
• Nonliving things need a push or a pull to be able to move.
Such a push or a pull is called FORCE.
3
•
A force is needed to start or to stop movement.
•
If an object is already moving, a force can make it move faster or slower, or change
its direction of movement.
•
Everything in the universe moves.
•
It might only be a small amount of movement and very slow, but movement does happen.
•
Don't forget that even if you appear to be standing still, the Earth is moving around
the Sun, and the Sun is moving around our galaxy.
•
The movement never stops called MOTION.
There are different kinds of forces. There are forces exerted by
1. People and animals,
2. Wind and water,
3. Electrical and magnetic force
4. Gravity

A force is a _________________ or a _________________.
It can make an object _________________. It can _________________ a moving
object. It can make a moving object move _________________ if it is slow and move
_________________ if it is fast.
A force can also make a moving object change its _________________.
5
Instruction: B. Paste at least 5 pictures below showing motion and explain each picture.

LESSON 2
How many of your toys move by themselves?
What is inside the toy that makes it move?
Such toys have batteries inside,
which provide electricity that makes them move.
The small amount of electricity in the battery
makes the motor inside the toy run.
7
Study the pictures below. Encircle the objects that move or work because of electricity.
8
Have you seen a magnet?
Have you ever played with a magnet?
With your mother’s permission,
look for a refrigerator and open it slightly and then
let it go. What do you observe?
Write your answers below.
The door should close by itself.
Doors of refrigerators have magnetic linings.
The magnet helps to keep the door tightly shut.
While magnets are good playthings, do not play with the refrigerator magnet.
9
Magnets are generally made of iron or steel.
The bar magnets and horseshoe magnets are the most common.
A magnet has an invisible force with which it pulls or pushes certain things.
This property of magnets to pull or push things is called magnetism.
The magnetic force at both ends of the magnet attracts or pulls objects toward itself.
Magnets attract or pull all objects made of iron.
Magnet can move some objects toward itself.
Electricity can move some objects.
Therefore, that electricity and magnetism are forces that make some objects move.
10
Instruction: A. Color the objects that move because of electricity.
11
Instruction: B. Encircle the objects which attracts a magnet.
scissors
basket
needle
iron nails
hairpins
ribbon
clothes
jewelries
Papers

LESSON 3
Earth pulls or attracts all objects down toward itself.
It is a force that pulls everything toward the earth.
This pull is called the force of gravity.
13
• It is most commonly recognized and experienced as the agent that
gives weight to physical objects, and causes physical objects
to fall toward the ground when dropped from a height.
Which is easier, to go down or to go up the stairs?
Going down is easy because gravity pulls you down.
When you go up, you have to lift yourself because you are going against gravity.
14
Instruction: Paste pictures of skydivers below. Describe their movements.
What makes skydivers fall? Explain your answers below your
pictures.

•
Forces are pushes and pulls.
•
There are different kinds of forces.
•
There are forces exerted by people and animals, forces exerted by wind
and water, electrical and magnetic force and gravity.
•
Magnets attract iron objects.
•
Magnets may attract or repel each other.
•
The earth pulls all objects toward itself due to the force of gravity.
