Instructions: Explore how solids, liquids and gases behave, and how heating and cooling change some materials. Read each question carefully and write your answers in the boxes. Use the water-cycle clues to explain how water changes state.

Solids, liquids and gases

Choose the state of matter that best describes each material at room temperature. Think about whether it keeps its shape and whether it can flow. Write one state in each box.

Word bank: solid, liquid, gas

1. An ice cube keeps its shape. It is a ___.

2. Milk can be poured and takes the shape of its container. It is a ___.

3. Air spreads out to fill a room. It is a ___.

4. A wooden ruler keeps its shape. It is a ___.

5. Water flows and takes the shape of a glass. It is a ___.

How do the states behave?

Choose the best answer for each question. Remember: a solid keeps its own shape, a liquid flows, and a gas spreads out to fill its container.

1. Which state keeps its own shape?

2. Which state can be poured and takes the shape of its container?

3. What does a gas do in a closed container?

Heating and cooling: melting and freezing

Use the facts in the word bank to help you. Water freezes at 0°C and ice melts at 0°C. Write the missing word or temperature in each box.

Word bank: melting, freezing, 0°C

1. Ice changes from a solid to liquid water by ___.

2. Liquid water changes into solid ice by ___.

3. Water freezes at ___ .

4. Ice melts at ___ .

Evaporation and condensation

Read each example and name the change of state. Evaporation happens when liquid water becomes water vapour. Condensation happens when water vapour cools and becomes liquid water.

Word bank: evaporation, condensation

1. A puddle gets smaller as liquid water becomes water vapour. This is ___.

2. Water droplets form on the outside of a cold glass. This is ___.

3. Wet washing dries as water leaves the fabric and becomes water vapour. This is ___.

4. Water vapour cools and forms tiny liquid droplets on a window. This is ___.

Follow the water cycle

Use the word bank to complete the water-cycle sentences. The Sun warms water at Earth’s surface, and water vapour cools higher in the air. Choose the correct process for each blank.

Word bank: evaporation, condensation, precipitation, collection

1. The Sun warms water in seas and lakes. Liquid water changes into water vapour by ___.

2. Water vapour cools and forms tiny droplets in clouds by ___.

3. Water falls from clouds as rain or snow. This is called ___.

4. Water gathers in rivers, lakes and seas. This is called ___.

Put the water cycle in order

The stages are mixed up. Write 1, 2, 3 and 4 beside the stages to show the repeating order of the water cycle, starting with water being warmed by the Sun. Use each number once.

___ Water vapour cools and condenses to form clouds.

___ Water collects in rivers, lakes and seas.

___ Water falls from clouds as precipitation.

___ The Sun warms water, and evaporation changes some liquid water into water vapour.
