5. Can you think of another way to separate the mixture into oil and water? If you think it would be possible, explain what you would do. 6. Do you think it would be possible to separate a mixture of juice and water using any of the methods that we have used so far (hand-separating, sieving, filtering or decanting)? Say why or why not. In the previous activity we mixed two liquids (water and oil) and learned that sometimes amixture of two liquids can be separated by decanting. Separating mixtures In the next section we will summarise all the dierent ways of separating mixtures. We have made dierent mixtures and tried to separate them using avariety of methods. In this section we will revise all these separation methods. ACTIVITY: Separating mixtures INSTRUCTIONS (Part 1) The table on the next page contains pictures of mixtures. 1. For each of the mixtures in the table, write which materials it is made up of in the middle column. 2. Write how you would separate the mixture in the column on the right. 128 Matter and Materials
