Show them to the students and ask what experiments we can do with them. Let the students show them and explain the reasons to the students. Let the students work in groups and discuss the experiments. 设计意图:教师拿出与课文中的实验相关的教学准备,导入新课,让学生分组研究实验流程,为课文的学习奠定基础. Leading in 情景2 T: Good morning/afternoon, everyone. Today we are starting a new unit. Who can tell me the title of Unit 5? S1: I can. It's "Look into Science". T:Very good. What is science? S2: Science is an area of study. S3: Science is something we learn about in school. T: In which subject do you often do experiments? S4: Science. T: Do you like experiments? S5: Yes. T: Experiments are part of something called the scientific method. The scientific methed: Ask questions →do background research →construct a theory →test the theory with an experiment →analyze results →draw a conclusion →report results (Was your theory correct?) OK. Today we'll learn an experiment. 设计意图:通过师生互动导入本课话题,教师向学生介绍实验的步骤,为本课的学习做好铺垫. Ⅱ．Presentation The teacher shows the new words on PPT. Ask students to try to read these words. The students follow the teacher three times. Then give the students five minutes to remember the words. Let students spell and read them one by one. 设计意图:教师以PPT的形式呈现本课中出现的生词,领着学生们朗读并记忆,为下面的课文学习做好充分准备. Ⅲ．Reading 1．Read the text aloud. T: Boys and girls, it's our reading time. Please read after the video and you should pay more attention to your pronunciation. 设计意图:让学生大声朗读课文,对课文的意思有个大致的了解,对于培养学生的正确发音以及培养学生的语感都有重要作用. 2．Careful reading. （1）Give the students five minutes to read the text by themselves. Read the lesson and answer the questions. a．Where does Danny think they should do the experiment? b．What keeps the water in the jar? c．Is Jenny sure of her theory? How do you know? d．Why does Danny put on his raincoat? e．What does Danny conclude? Keys: a Danny thinks that they should do the experiment outside. b．The force of the air. /The air pressure. c．Yes, she is. She is so sure of her theory that Brian can do the experiment over Danny's head and he won't get wet. d．Because he thinks he will get wet. e．Air is stronger than he thought. 设计意图:让学生再次阅读课文,提取文章的大意,加深对课文的理解. （2）Read the experiment. Put the sentences in the correct order. Put a piece of cardboard over the jar. The jar of water is upside down, but the water stays in the jar. This is because air pressure pushes the cardboard onto the jar. Fill the glass jar with water. Turn the glass jar over quickly. Hold your hand on the cardboard for a few seconds. Remove your hand from underneath the jar. What happens? There is more air outside the jar than inside, so there is more air pressure outside than inside. Keys: 251346 设计意图:学生对课文内容已经有了一定的了解,再次细读课文,掌握文章的细节. 3．Read the text and find out main phrases and sentences. Main phrases: ·turn…upside down ·pour out ·scientific method ·take…off Main sentences: I think the floor will get wet. We should do this experiment outside, Brian. That's called the scientific method. I am so sure of my theory that Brian can do the experiment over your head and I know you won't get wet. He puts on a raincoat and sits down. How is that possible? It is strong enough to hold the water. So what have we discovered? What do you conclude, Danny? Ⅳ．教材解读 1．Then I turn the jar upside down and take my hand off the cardboard. turn…upside down意为"把……翻转/倒过来",相当于turn over. upside down意为"正面朝下"right side up意为"正面朝上". take…off…在本句中意为"使……离开/脱离……"或"把……从……拿开". 拓展:take off意为"摘掉,(飞机)起飞,脱掉". 2．I think the floor will get wet.
