This is our evaporation experiment.  It is a glass of water; we leave on a sunny windowsill all the time.  The water has been turned green with food colouring.  Every week we check the level of the water.  We draw a circle around where the water is.  Each week the water goes down a little bit, it is evaporating.

Our topic is weather so we have learning about the water cycle.  Evaporation is an important part of the water cycle.

We are going to leave it for the whole of the October holidays to see what happens!
