Worksheet on Matter and Its States Class 3

Everything tangible exists as either solid, liquid, or gas, with amazing transformations occurring through heating and cooling. Young chemists observe ice cubes melting into water, steam condensing on bathroom mirrors, and dry ice sublimating directly into gas. This class 3 matter and its states worksheet demonstrates through investigations how temperature affects molecular movement, why balloons shrink in cold weather, and how pressure cookers work. Students conduct safe experiments watching matter transform while learning about particle behavior in different states. Download matter and its states worksheet Grade 3 pdf for molecular adventures.

1. Michael and his friends are playing with a ball shown in the picture. Which states of matter accurately represent the ball?

a) Solid only
b) Liquid only
c) Gas only
d) Solid and gas

Answer: d) Football is made of solid materials such as rubber and contains air inside to make it bouncy. Therefore, both solid and gas states of matter are present in the ball.

2. Which of the following will lose its shape if kept out in sunlight?

a)
b)
c)
d)

Answer: b) The ice cream will melt and lose its shape due to an increase in temperature.

3. Look at the picture below and identify the phenomena.

a) Evaporation
b) Melting
c) Condensation
d) Boiling

Answer: c) The picture shows the phenomenon of condensation. This occurs when water vapour in the air comes into contact with a colder surface (the glass), causing the vapour to cool and change into liquid droplets.

4. Which material do you think would be better for making a raincoat?

a) Cotton fabric
b) Plastic
c) Paper
d) Glass

Answer: b) Plastic is a suitable choice for a raincoat because it is waterproof.

5. Match the following.

a) 1:A, 2:B, 3:C
b) 1:C, 2:A, 3:B
c) 1:B, 2:A, 3:C
d) 1:A, 2:C, 3:B

Answer: d) Molecules are closely packed in solids.
In liquids, the molecules are not very closely packed.
In gases, molecules are placed far apart from each other.
