Spring Festival and Lantern Festival in our country people like to see the lion dance and guess the riddles Do you like to guess the riddle then Ss Yes T OK Now I have a riddle Please guess it Teacher uses the multimedia to show the riddle on the screen It s very important to all the animals and plants It s also important to human beings It s liquid at room temperature Every day you keep in touch with it You can t live without it a thing T What s it Ss It s very easy It s water T Yeah today we will talk about water Now please tell me what you know about water S1 Water is used to drink S2 Water can be used to water the flowers S3 I think water can be used to make electricity Step Warming up T Thank you for your ideas Next we will make some interesting experiments Maybe you can learn more about water from the following experiments S4 would you like to come here to help me S4 I d love to T Now look at Li Lei and me We will begin You should watch the experiment carefully and try to tell me what happens and why Teacher puts a bottle of water a bottle of vegetable oil and an empty glass on the desk T S4 pour some water and some vegetable oil into the empty glass Other students please watch carefully A few seconds later Ss Fantastic The liquid in the glass has become two parts T Try to describe it in detail S5 Let me try The part above is vegetable oil and the part below is water But I don t know why T Good question Who d like to answer his question Nobody answers his question T Perhaps it is a little difficult to answer it immediately Now you can have a discussion about the reason for it using what you have learnt in physics Teacher lets students discuss in groups of four A few minutes later teacher checks their answers T Who wants to explain the phenomenon S6 I think water is heavier than oil so vegetable oil is on the top of the water T Who has different ideas S7 I think we should say that the density of water is higher than the density of vegetable oil so the result formed S8 What s the meaning of density S9 Density is 密度 in Chinese T Do you agree with the reason for it Ss Yes We agree with the idea T As we know if we pour milk and water into one glass we can t tell where water is and where milk is But just now we poured oil and water into one glass it is so different now Do you know why Ss Because oil can t dissolve in water but milk can T Very good Let s make a summary about the experiment If we pour vegetable oil and water into one glass the liquid will become two parts because oil can t dissolve in water Since the density of water is higher than vegetable oil vegetable oil will be on top of the water Is that clear Ss Yes T Would you like to watch another experiment Ss I d love to T OK I ll perform the next experiment by myself Look at me I have a glass of water Now I ll cover it with a piece of thick paper Attention please Teacher puts one hand on the paper and turns the glass upside down Then teacher slowly takes his her hand away from the paper T What can you see Ss The piece of paper doesn t fall and the water in the glass doesn t flow T Yes You are right Now you are given a few minutes to have a discussion about the reason for it Teacher gives students a few minutes to discuss and then checks their answers T Who can tell us the reason why the piece of paper doesn t fall and the water doesn t flow S10 I want to have a try When the glass of water covered with a piece of paper is turned upside down the pressure from air to the piece of paper is bigger than the pressure from the water in the glass to the piece of paper So the paper won t fall and the water won t flow T Excellent Thank you for your explanation I am very glad to see that you are all interested in making experiments After class you can carry out another two experiments on Page 17 When you perform them try to describe what happens and why OK Ss OK T Now let s look at a picture Teacher shows a picture on the screen T What can you see Ss There is a river in the picture but it s very dirty T Anything else S11 There are some plastic bags and empty tins on the surface of the river T Yes We all know water is important to human beings and all the animals and plants Unfortunately water is being polluted now What do you think we can do to protect the water on our planet Teacher gives students enough time to prepare When they prepare teacher goes among the students to help them to express their ideas correctly Sample answer To protect the water on our planet I think we should save every drop of water and stop throwing rubbish into water Besides we should try our best to help the people around us realize the importance of using and protecting our water Step Listening T Next let s do some listening Turn to Page 18 and look at the Listening part You can listen to the famous poems about life on the ocean Listen carefully and write down some key words when you listen Before you listen let s learn two phrases first Look at the

down the information Play some parts of the tape one more time if necessary Finally teacher checks the answers with the whole class Step Speaking T In our daily life water can be used in different ways Now we ll talk about the ways in which water can be used Look at the pictures on Page 18 The six pictures mean six different ways to use water You can choose one of the pictures to discuss the importance of using and protecting our water and then try to use some sentences to describe the picture you choose If you like you can make a dialogue with your partner about the picture When you discuss you may use the questions on the screen to help you 1 How is the water being used 2 Is this a good way to use water 3 Why do we use water in this way 4 Who benefits from using water in this way 5 What are some disadvantages of using water in this way Teacher shows the questions on the screen by multimedia and gives students enough time to discuss and prepare Suggested answers Picture 1 We can use water to make electricity which can give us light and make us feel warm I think it is a good way to use water Picture 3 Water has a lot of usages and home use is the commonest one Every day we must drink enough water In addition we need a lot of water just for cooking and keeping clean Water can help us to keep healthy But if the waste water from home use is poured into river and soil it will be harmful for some animals and plants So we must pay more attention to it Picture 4 In Picture 4 water is being used in industry Water is very important to industry It can be used to make paper cool machine and so on But the disadvantage is that a lot of water mixed with some poisonous things being poured into the river and the sea It is dangerous for the living things in the water Picture 6 A Do you know how the water is being used in Picture 6 B Water is being used for entertainment A Is it a good way to use water B Yes because it can help people keep fit and enjoy nature But if people
