Boiling and evaporation
Investigation
To see if evaporation takes place when we boil a kettle.
Method
We are going to measure the amount of water we pour into a kettle. Then we will
boil the kettle. After the kettle has boiled we will pour the water into a measuring
jug to see how much water there is left.
Prediction
I think that:

Results
Amount of water at the start _____________
Amount of water after boiling _____________
Conclusion
Put the following labels on the diagram to show what happened in your experiment.
Then write a sentence to explain what happened and why below.

Temperature, air flow and evaporation
Investigation
To investigate whether temperature and air flow have an effect on
evaporation.
Method
We will wet some cloths and some paper towel. We will then put one of each on the
washing line in the classroom, one of each outside and we will put one of each in
front of a hairdryer. After a certain time we will test to see in which location the
most evaporation takes place.
Prediction
I think that the cloth/paper towel ___________________ will dry first because

Conclusion
Using and labelling the diagram, describe what effect the hairdryer has on the rate of
evaporation.
