Write an explanation paragraph Teaching Plan: (Six Periods) 1st period: Warmingup and Speaking 2nd period: Listening 3rd period: Reading 4th period: Integrating Skills 5th period: Grammar 6th period: Exercises Period 1 Warming up amp。 Speaking Teaching Aims and Demands: 1. To get the Ss to understand the main properties of water by connecting them with some mon phenomena and learning to explain the phenomena. 2. To enable them to be aware of the importance of water, making good use of water in a proper way and protecting water resources. Teaching Difficult Point: Talk about how to use water and protect it. Teaching Aids: Some water, some oil and a glass。 blackboard and multimedia Teaching Procedures: Step1. Leadin Ask the Ss some questions as follows T: Water is around us and inside us. We can‘t go without water. Qs: Why is water so important to living things? Can you point out some of its properties or characteristics? Suggested vocabulary: It39。s colorless, tasteless, odorless and universal dissolvent. It feels wet。 It exists in three forms: liquid, solid, gas, and is cycled through the water cycle。 It can absorb a large amount of heat。 It sticks together into beads or drops。 It39。s part of every living anism on the pla。 etc. Ask students the names of Oceans and Continents: The Pacific Ocean, the Atlantic Ocean, the India Ocean, the Arctic Ocean。 Asia, Africa, Europe, the North America, the South America, Antarctica, Oceania Step2. Warming up Use the water, the oil and the glass to do three experiments. Learn more about water‘s properties by doing some simple experiments and learn to describe an experiment. What property of water does each of the four experiments illustrate? What causes this phenomenon? What‘s this phenomenon related to? ① Experiment 1 shows how air pressure causes a piece of thick paper to cling to an upturned glass of water. ② Experiment 2 illustrates how substances with different density behave when placed in the same container. ③ Experiment 3 is an example of how water dissolves substances and objects. ④ Experiment 4 illustrates some of the differences between salt water and fresh water. Step3. Speaking 1. Prespeaking 1) Do you agree with the saying ―Without water, life would not exist. ‖ ? 2) So not only you and I agree with this opinion, but also the United Nations hold the same view. And that‘s why we have World Water Day. Q: Is there anyone who knows when it is? － Mar. 22 3) Brief background information about World Water Day: World Day for Water is established by the United Nations General Assembly39。s resolution 47/193 of 22 December 1992. It is a unique occasion to remind everybody that concrete efforts to provide clean drinking water and increase awareness worldwide of the problems and of the solutions, can help make the difference. 4) Last year we witnessed some great disasters such as the typhoon ―Yunna‖ and the tsunami in the India Ocean. What a coincidence that the theme for World Water Day 20xx was ―Water and Disaster‖. World Water Day 20xx will be guided by the uping water decade39。s theme Water for Life. It will be the starting day for this International Decade for Action, Water for Life. 2. Whilespeaking 1) To some extent, the existence of World Water Day also implies that human beings cannot live without water. Why? Can you tell how water is being used in our life? Give some examples. － Electricity, agriculture, home use, industry, transport, entertainment, etc. 2) Look at the first picture (―electricity‖) in the textbook and talk about it. The water is being used to generate electricity. Building up behind a high dam, water accumulates potential energy (勢能 ). This is transformed into mechanical energy when the water rushes down. It is a good way to use water because water is renewable green energy. It will never run out if only we use it properly and generating electricity by using water is a better way to protect the environment than others. However, it takes a great sum of money and a long period of time to build a dam and prepare all the required equipment. Since nowadays electricity has already been an indispensable part of our life, most people benefit from using water in this way. 3) Group work. Divide students into several groups with six in each. Each one takes charge of one picture. When discussing each picture, please think about the following questions: How is water being used? What property of water enables it to be used in this way? Why do we use water in this way? Who benefits from using water in this way? Is this a good way to use water? What are some disadvantages of using water in this way? 4) Pair work. Each sixmember group can be divided into three smaller ones with two in each. Make a dialogue on the basis of the results about your topics we reach, using following useful expressions: The water is being used to / for … We should / could … What will we do if …? If we … , we can … It would be better to … Can you think of a better way Step 4. Homework: Recite the new words and expressions in this unit.
