1、Module 5A Lesson in a Lab【美文阅读】How to create a rocket balloonTo create a rocket balloon, youll need the following items: a balloon (any size), a piece of string (10 to 25 feet), a straight drinking straw (吸管), tape. First, you have to create a “track” for the rocket balloon to run on. You begin by t
2、ying one end of the string to a tree, post, chair, or any other strong support. Then slide (使滑动) the free end of the string through the drinking straw.

3、o one end of the string. Fill the balloon with air. Hold the neck tightly to keep it full. Using two pieces of tape to attach the balloon to the straw.

4、sed, the air in the balloon has nowhere to go, so it pushes back to keep the balloons shape. However, since the mouth is open when you release it, the air has somewhere to go. The air pushes out the mouth of the balloon. Since the air is now moving, the rocket balloon also moves. This follows Newton
5、s Third Law of Motion (for every action theres an equal and opposite reaction)There is friction (摩擦) between the string and the straw, but the straw is made of material thats smooth and the weight of the balloon and straw is light, so the overall frictional force is very small.It is the same when ro
6、ckets work. They burn fuel to push matter out the back forcefully. The rocket moves in response to this. Since a rocket weighs much more than a balloon, of course, it takes more fuel to get it moving.【诱思导学】1Do you like doing scientific experiments? What are the stages of a scientific experiment? .【答
7、案】Yes, I do. The stages are as follows: aimmethodresultconclusion.2What will happen when the air in the balloon is receased? .【答案】When the balloons mouth is open，the air will push the balloon to move.Period Previewing(教师用书独具)教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，对下一堂课对课文的全面理解起到一个铺垫
