Evaporation is the change in state from a liquid to a gas.

Temperature is a measure of how hot something is.

Variables are the things that can be changed, measured or kept the same in a comparative or fair test.

In a conclusion, scientists explain what the results show or mean.

Temperature and evaporation: do and review

Science

In this Introduction to states of matter and changing states unit, pupils learn that some materials change state when they are heated or cooled. In the Properties, changes and separating materials unit, they will build on this knowledge to learn that dissolving, mixing and changes of state are reversible changes

In the Everyday materials unit, pupils learnt to compare and group together a variety of everyday materials on the basis of their simple physical properties. In this Introduction to states of matter and changing states unit, pupils will build on this knowledge to compare and group materials together according to whether they are solids, liquids or gases

Physical activity and equipment requiring safe use

Scientists use a range of equipment to make careful __________.

Which of these diagrams shows evaporation? 

Match the equipment to the measurement you would make with it. 

The speed of evaporation is not affected by temperature. 

Evaporation gets slower as temperature increases.

Evaporation gets quicker as temperature increases.

How does the speed of evaporation change as temperature increases? 

Evaporation is not affected by temperature.

Evaporation gets quicker as temperature increases. 

Which of these conclusions do these data support? 

In which state does water take the shape of the bottom of its container? 

In which state does water have a fixed shape except when a force is applied to it? 

Put the forms of water in order, from the one which would occur at the lowest temperature, to the one which would occur at the highest temperature.  

{{}} are the things that can be changed, measured or kept the same in a comparative or fair test.
