1. S1 Chemistry Matter REVISION I can apply my knowledge of how water changes state to help me understand the processes involved in the water cycle in nature over time. SCN 2-05a NEW LEARNING By contributing to experiments and investigations, I can develop my understanding of models of matter and can apply this to changes of state and the energy involved as they occur in nature. SCN 3-05a

27. Starter Questions 1. Write down 3 ways in which a liquid is different from a solid 2. Is custard a solid or a liquid? Explain why you think this!

28. Changes of State Today we will learn to Describe the ways in which solids change to liquids and gases. We will do this by Revising the water cycle and practicing the words which describe each of the changes We will have succeeded if

29. The Water Cycle In your groups: 1.Put the ice in a beaker on a tripod. 2.Heat the ice and observe what happens 3.While you are doing the experiment, try to draw what is happening to the particles in the ice as you heat it… Clue: the particles in a solid look like:

30. The Water Cycle When solid water (_____) is heated, it becomes a _______. This process is called __________. When liquid water continues to be heated, a _____ forms. The formation of a gas from a liquid is called __________. When the steam cools down again (_________) it returns to liquid form. A solid can be reformed by ____________.

31. The Water Cycle When solid water (ice) is heated, it becomes a liquid. This process is called _melting___. When liquid water continues to be heated, a gas forms. The formation of a gas from a liquid is called evaporation. When the steam cools down again (condensation) it returns to liquid form. A solid can be reformed by ___freezing__.

36. A Confusing Matter! When cornflour paste is mixed with water, the particles can behave like a liquid or a solid! Not all particles are the same! The smallest particles which can exist on their own are ATOMs When atoms join together they make MOLECULES. John Tickle walks on custard
