2019-2020学年度人教版必修五Unit 1Great scientists Period 1Warming up and reading教案

　　The General Idea of This Period

　　The unit centers on "great scientists". This is the first period of this unit. During this period, the students should be encouraged to give their previous knowledge of some of the famous scientists, participate in the activities in class and try to get more information from the discussion. They will take part in different forms of activities, including pair work, group work, competition, and quiz. Group competition will be carried out all through the class.

　　Words and expressions in this unit will help the students to talk about the topic "great scientists". So at the beginning of this period, the teacher should spend some time training the students to read them and help the students pronounce them correctly. The students are encouraged to learn the new words in groups by themselves, using dictionaries and other reference books. Then more time should be given to the students to get familiar with the words and expressions. Lastly, several sentences will be given to the students to help them to know how to use some of the phrases.

　　This unit is about "great scientists", so from the very beginning, the teacher can encourage the students talk about their dreams in the future. Then the teacher can let the students brainstorm something about great scientists. The students are free to say anything that they know. The students will be quite interested in this topic. This activity gives the students a chance to express their feelings about their favorite scientist. At the same time, this activity can stir the students' enthusiasm in science.

　　Then the teacher can have the students match the famous scientists with their discoveries, inventions or theories, making sure that they have some common sense about some world-famous scientists.

　　Later the students will be divided into several groups, describe one of the great scientists and let other students guess who he or she is talking about. In this way, the students should learn to organize their own sentences and express their ideas clearly.

　　After that, the students will feel comfortable to do the quiz in the text. The students should be encouraged to give more information about these ten scientists.

　　Meanwhile, the students' interest in scientists and science should be cultivated. So two topic discussion questions, as well as the practice exercises are designed.

　　The post-class activities are designed to arouse the students' interest in science and encourage them to "DIY-do it yourself" in their daily life if they have some doubt in some areas.
