Today we are going to look at evaporation and condensation. Click the video below to find out more and then complete the activities further down the page. There is also an experiment for you to try and the bottom of the page!
Which container lost the most water?
Why did A not lose any water?
What is the process called when water turns from a liquid to a gas?
Did the shape of the container affect how much water was lost? Explain your answer.
What do you predict would happen to the amount of water lost if Lara had used a container much bigger than E?
Put the same amount of different liquids in the same type of containers and leave them all in the same place. Observe what happens over a few days. Record your results.
Put a saucer of muddy water on your windowsill and see what happens.
You should see that the water evaporates and rings of dirt appear. Do the same again, but put the saucer somewhere else and compare your results. Do the rings look the same?
Can you explain what has happened?
