Lesson

Pre-reading questions: - Why is rain important? - What’s evaporation? 3. Read the page from a science book. Number the paragraphs in the correct order SB Page ??

The water cycle Water moves around the earth all the time: it is recycled by nature. This is called the water cycle. So what happens? a 3 How are clouds formed? In the sky, these small drops of water are blown together by the wind. When billions of the small drops join together, they form clouds. b 5 How is snow made? Water drops do not always become rain. When it is very cold, water drops turn into ice and fall to the ground. This is snow. 235

UNIT

16 c 1 What is evaporation? When the sun shines, it causes the water in rivers, lakes and the sea to evaporate. This means that water is turned from a liquid into a gas. This gas is called water vapour. d 4 How is rain made? If the drops are very big and heavy, they fall through the clouds to the ground. This is rain. e 2 What is condensation caused by? As the water vapour moves up into the air, it becomes cooler. The water vapour changes into very small drops of water. This is called condensation. You can sometimes see condensation on the inside of a window.

Post-reading questions 3 Choose the correct answers: 1. (Evaporation / Condensation) is when water turns to water vapour. 2. Water vapour is a (liquid / gas). 3. Water vapour (moves up into / falls down from) the sky. 4. Clouds donâ&#x20AC;&#x2122;t form when there is no (sun / wind). 5. (Snow / Rain) forms when it is very cold.

Lesson

Pre-listening question: - Where are experiments done? - Can you guess what the experiment shows? 3. Listen to a teacher doing the experiment in a science class and check your answers to exercise 2

SB Page ??

Teacher : Now, we are going to do an experiment with water and salt. First pour some water into two plastic cups. Fill the cups to about half way. Now, add some salt to one of the cups. Stir the salt into the water with a spoon. Boy 1

: Do you mean like this? [water being stirred by a spoon]

Teacher : Good. As you stir the salt it will disappear. Are you following me? 247

UNIT

16 Boy 2 : Yes. I can’t see it at all. Teacher : Keep adding more salt until it doesn’t disappear any more. Do you understand what I mean? You’ll need quite a lot of salt about a third of a cup. Now, put both cups in the freezer for three hours. Teacher : OK, let’s see what’s happened to the water in each cup. Boy 1 : Only one cup of water has become ice! The other cup hasn’t changed at all. Teacher : Yes, that’s because when salt is added to water, it doesn’t freeze at the same temperature. Water with salt in it has to be much colder to freeze. Is that clear to you? Boy 2 : Yes, I see what you mean. Boy 1 : Can I just check that I have understood correctly? Is that why the sea isn’t usually frozen even in the winter, because the water contains salt? Teacher : That’s right Boy 1 : I understand! How interesting!

Post-listening questions 3 Put these sentences in the correct order: Put both cups into the freezer. Add salt into one cup. Only one cup of water is frozen. Stir the salt, which will disappear. 248
