Year 5 have been learning about separating materials. They have carried out experiements including using different sieves to separate materials. In this lesson the children were given a range of substances including sugar, salt and coffee to observe the reaction when mixed with water. They were able to see whether the substance mixed with the water to become a solution .
They learnt that some substances are soluable and others are not. They will use the same solutions to see the effects of evaporation after 2 weeks.
