Put your ice cube on top of the bottle. 3. Put the black paper behind the bottle and watch what happens next. - some hot water in a jug - clear glass bottle - an ice cube - some black paper Write up your experiment: Start like this: 1. What we used. 2. What we did. 3. What happened. 1. What was in the warm air rising up from the hot water? 2. What happened when the warm air hit the ice cube? 3. Think about the water cycle. What do you think happens to the warm moist air rising up from the sea as it gets higher and higher. Clues to help you: As the water vapour rises high up in the sky, the air gets cooler. The water vapour condenses making the tiny drops of water in the vapour a bit bigger. They are no longer invisible and form a cloud.
Saving The Water Water Cycle - Worksheet 7 Making Rain How to find out: 1. Put some warm water in a plastic fish tank. 2. Stretch cling film over the top of the tank. 3. Put 3 or 4 ice cubes in a pile at one end of the cling film. Pucker the surface of the cling film so that they are kept in the same position. Watch what happens. 1. Where does it start to rain? 2. Why does it rain there? 3. Where does the rain fall? Think about the Water Cycle. What happens to the rain after it falls to the ground? -plastic fish tank -some cling film -some ice cubes Clues to help you: When you breathe out, water evaporates from your lungs. It forms vapour in the air. How ice cubes in a beaker cause condensation. The ice cubes in the beaker start to melt. The air in the beaker is warm to start with and the water evaporates. The air in the beaker slowly cools down as the ice cube melts and eventually the air is cold enough for the water droplets to condense on the surface of the cling film. This is because the air in the beaker is now colder than the air in the classroom.

True False 5. When clouds are full of water droplets they fall as rain, hail or snow. True False 6. The rain falls on to the land and stays there. True False
Saving The Water Water Cycle - Worksheet 9b Water Cycle Quiz Answer Sheet 1. True. It is a natural system in our environment and has been happening in the same way for millions of years. 2. True. This is called evaporation. 3. False. Water vapour is made up of tiny droplets that we cannot see. 4. True. The tiny water droplets bump together forming bigger drops that we can see as clouds. 5. True. The clouds may be blown towards the land and precipitation happens. Watch the weather forecast and listen carefully and you will hear the word precipitation. 6. False. Rain falls onto the land and into rivers which flow back into the sea and the Water Cycle begins again.
