Separating Water

Following on from looking at river formation, we have started to look at separating and purifying water. We firstly collected some water from the school pond. This water was dirty and full of sediment. In order to clean the water, we had to decanter it into jugs, let it settle and then sieve it into another jug removing some of the dirt. The next step was to filter it into another jug. These pictures show the children in action.
