2 Mixtures NEW WORDS • mixture • separate • variety 118 KEY QUESTIONS • What is amixture? • When is amixture also asolution? • How can mixtures be separated into dierent materials? 2.1 Mixtures of materials What is amixture? A mixture is two or more dierent materials that have been mixed together. In some mixtures, the dierent materials are still clearly visible after mixing. A mixture of peanuts and raisins would be an example of such amixture. How would we separate the peanuts and the raisins? Well, we could simply pick the raisins out of the peanuts! A mixture of peanuts and raisins. Can you think of other mixtures in which the dierent materials are still clearly visible after mixing? Look at the pictures below for some ideas.
A mixture of dierent coloured jelly beans. A mixture of swans and ducks on a lake. A mixture of pink, yellow and white flowers. A mixture of dierent fruits in a fruit salad. A mixture of red, green, yellow and orange sweet peppers. A mixture of dierent shells from the beach. In other mixtures, the materials are mixed so thoroughly that it seems one material has 'disappeared' into the other. Such mixtures are called solutions. We will learn more about solutions shortly.
