States of Matter

Help a science team explain what happens to matter as it is handled, poured, heated and cooled. Read each question carefully. Use evidence about shape, volume and changes of state.

Explore the states

Matter has mass and takes up space. In this activity, focus on the three familiar states: solid, liquid and gas.

1.A sealed lunchbox contains an apple, a little yoghurt and air. Which statement best explains why all three are matter?

They can all be seen clearly.
They all have mass and take up space.
They all keep their own shape.
They are all made of water.

2.Complete the particle description: In a solid, particles are packed close together and usually in place.

3.Complete the particle description: In a liquid, particles can past one another.

4.Complete the particle description: In a gas, particles are far apart and move .

5.Match each lunchbox example to its state of matter.

Apple
Yoghurt
Air inside the sealed lunchbox

Gas
Solid
Liquid

6.Mere pours juice from a bottle into a wide bowl. The juice changes shape but its amount stays the same. What does this show about liquids?

7.True or false? A gas spreads out to fill the space available to it. Give one example to support your answer.

TrueFalse

Follow the water

Water can change state when it gains or loses heat. Use the process words carefully: melting, freezing, evaporation and condensation.

8.A frozen ice block is left in the sun and becomes liquid water. Name the change of state and say whether the water gained or lost heat.

9.Water vapour touches the cool outside of a glass and forms tiny drops. What is this change of state called?

10.A puddle slowly disappears on a breezy day, even though it is not boiling. Explain what happens to the water.

11.Water vapour cools and forms liquid droplets on the outside of a glass. What change of state is happening, and what evidence in this description supports your answer?

12.A sponge keeps its overall shape when lifted, although water can soak into its holes. Is the sponge itself a solid or a liquid? Explain why the holes do not make it a liquid.

13.A learner says, “When an ice cube melts, it stops being matter.” Correct the claim using the ideas of matter and state change.
