Science at key stages 1 and 2    (Year 5)

• that evaporation is when a liquid turns to a gas
• to explain 'disappearance' of water in a range of situations as evaporation

• that liquids other than water evaporate

• to turn ideas into a form that can be investigated, to make a prediction and decide what evidence to collect
• to construct a fair test

• to make careful measurements, recording them in tables and graphs
• to identify trends in results and use these to draw conclusions, indicating whether the results support the prediction
• to explain conclusions in terms of scientific knowledge and understanding

• to explain everyday examples of 'drying' in terms of factors affecting evaporation

• that condensation is when a gas turns to a liquid
• that condensation is the reverse of evaporation
• to make careful observations and draw conclusions explaining these in terms of scientific knowledge and understanding

• to make careful observations and draw conclusions, explaining these in terms of scientific knowledge and understanding
• that air contains water vapour and when this hits a cold surface it may condense

• that the boiling temperature of water is 100?C
• to identify patterns in data and use these to make predictions
• to decide whether the evidence collected supports the prediction and explain what happened in terms of scientific knowledge and understanding

• to obtain evidence by making careful observations
• to make predictions using scientific knowledge and understanding

• that melting, freezing, condensing and evaporating are all changes of state which can be reversed

• that water evaporates from oceans, seas and lakes, condenses as clouds and eventually falls as rain
• that water collects in streams and rivers and eventually finds its way to the sea
• that evaporation and condensation are processes that can be reversed
• to interpret the water cycle in terms of the processes involved
