Third Class Science

In Science recently we investigated different ways of separating mixtures of liquids and solids. We discovered that mixtures like water and stones can be separated simply by decanting (or pouring). We learned that sieving is a useful way of separating a mixture like water and rice. To separate water and sand we used filter paper and funnels. This is known as filtration . Finally we were unable to separate salt and water as the salt had dissolved to create a solution. Our teacher explained how the process of distillation can be used to separate mixtures such as these.
