Module 5 A Lesson in a Lab【美文阅读】How to create a rocket balloonTo create a rocket balloon, you'll 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 tying 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. Tie the other end of the string to another support (generally at the same height). Make sure the string is taut(绷紧的) when tied down.Move the straw to 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. The mouth of the balloon should point toward the nearest support. Then release the balloon and watch it go!When the mouth of the balloon is held closed, the air in the balloon has nowhere to go, so it pushes back to keep the balloon's 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's Third Law of Motion (for every action there's an equal and opposite reaction)．There is friction (摩擦) between the string and the straw, but the straw is made of material that's smooth and the weight of the balloon and straw is light, so the overall frictional force is very small.It is the same when rockets 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】1．Do you like doing scientific experiments? What are the stages of a scientific experiment?.【答案】Yes, I do. The stages are as follows: aim—method—result—conclusion.2．What will happen when the air in the balloon is receased?.【答案】When the balloon's mouth is open，the air will push the balloon to move.Period ⅠPreviewing(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作用。

And the twins, Alisa and Alan. And then Helen. Five children. I was too busy raising them to grow a garden.Money was tight, as well as time. Often when my children were little, one of them would want something that cost too much, and I’d have to say, “Do you see a money tree outside？Money doesn't grow on trees, you know.”Finally, all five got through high school and college and were off on their own. I started thinking again about having a garden.I wasn’t sure, though. I mean, gardens do cost money, and after all these years I was used to living on a pretty lean, no-frills budget.Then, one spring mor ning, on Mother’s Day, I was working in my kitchen. Suddenly, I realized that cars were tooting their horns as they drove by. I looked out of the window and there was a new tree, planted right in my yard. I thought it must be a weeping willow, because I saw things blowing around on all its branches. Then I put my glasses on—and I couldn’t believe what I saw. There was a money tree in my yard!I went outside to look. It was true！There were dollar bills, one hundred of them, taped all over that tree. Think of all the garden flowers I could buy with one hundred dollars! There was also a note attached: “IOU eight hours of digging time. Love, Marvin.”Marvin kept his promise, too. He dug up a nice ten-by-fifteen foot bed for me. And my other children bought me tools, ornaments, a trellis(棚架), a sunflower stepping stone and gardening books.That was three years ago. My garden’s now very pretty, just like I wanted. When I go out and weed or tend my flowers, I don’t seem to miss my children as much as I once did. It feels like they are right there with me.I live up in Michigan’s Upper Peninsula, where winters are long and cold, and summers are too short. But every year now, when winter sets in, I look out of my window and think of the flowers I’ll see next spring i n my little garden. I think about what my children did for me, and I get tears in my eyes every time.I’m still not sure that money grows on trees. But I know love does!1. By saying “Do you see a money tree outside…”the mother actually means “________”.A. Observation is the best teacherB. Seeing is believingC. The outsider sees the most of the gameD. It is not easy to gain money2. The best title for the passage would probably be ________.A. My flower gardenB. Marvin helps to realize my dreamC. Love in MichiganD. Money grows on trees3. The underlined word “no-frills” in the fifth paragraph is similar in meaning to ________.A. wastefulB. tightC. absurdD. helpful4. From the last three paragraphs we can infer that the mother is________.A. divorced when she was youngB. not caring for her kids any longerC. alone but not at all lonelyD. prouder with her garden than with her kids六、书面表达假定你是中学生李华。
