QUESTIONS
STATION 1
Force is required in most of our daily activities. All activities thatinvolve movement of the body require force. Force can change theshape, position, speed or direction of the movement of an object.There are many types of forces.
In the following task, you will identify four types of forces.
Materials/ apparatus
A coin
A plasticine ball
A plastic ruler Wool cloth
Some bits of tissue paper
Two magnets
Procedure
Carry out the activities below. Then, write down your observation andidentify the four types of forces.
1. Slide a coin on the floor.2. Lift a plasticine ball from the table and drop it to the floor.3. Rub a plastic ruler with a woolen cloth and bring it close to
some tiny bits of tissue paper.4. Bring the south pole of a bar magnet close to the north pole of
another bar magnet.5. Record your observations in the table given.
