- Discuss results with the children and help them to present them as a graph. Compare results from different investigations and ask children what the results show about the factors affecting evaporation, to make generalisations and to try to explain eg the warmer the place, the faster it evaporates; washing dries better on a windy day, I know this because the water evaporated faster by the open window than in other places.

- with help in choosing what to do, present results in a graph eg showing volume of water against number of days for each container
- compare results to draw conclusions eg this one went down faster than that one. This means the water in the container with the large opening evaporated faster than in the other ones. This is what I expected, the larger the opening the faster it evaporated
