Key Stage 1
Meaning
Water is a transparent liquid needed by all life on Earth.
About Water
- Water is can be used to wash clothes because it is a liquid.
- Water flows down rivers and into the sea because it is a liquid.
- If water gets too hot it turns into steam.
- If water gets too cold it becomes ice.
Key Stage 2
Meaning
Water is a transparent liquid needed by all life on Earth.
About Water
- Water can be frozen into ice if it is cooled down below 0°C.
- Water evaporates into water vapour.
- The higher the temperature the quicker water evaporates.
- At 100°C water boils and turns into steam.
Key Stage 3
Meaning
Water is a liquid (at room temperature) chemical compound with the chemical formula H2O.
About Water
- Water can be frozen into ice if it is cooled down below 0°C.
- Water evaporates into water vapour.
- The higher the temperature the quicker water evaporates.
- At 100°C water boils and turns into steam.
- Water reacts with metals above Hydrogen on the reactivity series to produce Metal Hydroxides which are alkaline.
