瓶子吞鸡蛋实验~

实验过程：将烧的纸条塞入小口的瓶子里，在瓶口上放个去壳的鸡蛋，鸡蛋便被“嘬”了进去。 实验原理：纸条燃烧消耗了瓶中的氧气，瓶内气体体积减小，瓶内压强减小（小于外部压强），鸡蛋就被大气压压进瓶子了

Teacher: teacher gave us a magic show, if the show is successful, you feel pretty good, a little encouragement to the teacher.
(Present: jars, a peeled cooked eggs, place eggs in the bottle)
Teacher: Who came up hand pressing eggs, see if I can put it into the bottle press, but not the eggs crumble.
Student: the bottle is too small, eggs do not get.
Teacher: The teacher is not by hand, there is a way to make eggs fall into the bottle, you believe it?
Students: do not believe.
Teacher: Please pay attention to see the teacher performing magic (lit a piece of paper into the jar, quickly put the bottle down on the small mouth eggs, egg quickly into the bottle)
Student: wow! Amazing! (applaud)
Teacher: Thank you for your applause. The magic interesting?
Student: so much fun!
Teacher: What do you see? What is interesting?
Student: I see a little bit of eggs being swallowed a bottle, as if there is a bottle inside the suction force.
Teacher: So what do you think is the reason?
Student: I think it may be with the burning of paper, since the teacher after the burning of paper thrown bottles, eggs was only sucked.
Teacher: You are a good reason.
Student: I give him to add that paper burning oxygen in the bottle ran out, so I think it may be related with the air.
Teacher: We observed very carefully, very rich imagination, that in the end who is a force with the egg it, air it? This lesson we have to study together, "bottle swallow eggs Secret" (Blackboard topics)
Second, the inquiry: understanding the atmospheric pressure
1, sucker, for example, to guide students to a preliminary "know" the existence of atmospheric pressure.
Teacher :( present: rubber suction cup) What is it? What is the use? how to use?
Student: This is sucker can suck on glass or wall, hang things on it.
Teacher: That how to use it? Who will show you. (To produce a glass, let students demonstrate)
Teacher: I'm also a sucker that I try, (the sucker gently on the glass, deliberately not forced by) how suck live ah? (Revealed puzzled look)
Students: teacher, you have to press the suction cup firmly down.
Teacher: Oh, I try (forced by sucker) hey, really suck up.
Teacher: Press firmly to suck and gently put up simply suck live, how is this going? We compared the two suction cups to see what's the difference? What is the relationship with the air?
Student: Under a sucker air, it can not suck on the glass; the second sucker no air can be sucked tightly on the glass. I think, and air-related, in the end what is the reason I do not know.
Teacher: That teacher everyone.
① around us is full of air surrounding our planet surrounded by a thick layer of air was, how thick it, there are about 2000-3000 km thick, we put a thick layer of air called the atmosphere. Atmosphere is the weight, so objects in the air will be subject to an invisible atmospheric pressure, which is the atmospheric pressure. (Deputy Blackboard) ② (refer suck sucker) is not under air sucker, and there is no atmospheric pressure, but also by the outside atmospheric pressure sucker, sucker so not suck on the glass but by atmospheric pressure "pressure" on the glass. (Referring to not suck sucker) under air sucker, outside air also, two atmospheric pressure cancel each other balanced, so it could not suck up.

The experiment process: the burning paper into small mouth bottle, put a shell on the bottle of the egg, egg will be "sucked" inside. The experiment principle: the note burning oxygen bottle, bottle gas volume decreases, the bottle pressure is reduced (less than the external pressure), egg is atmospheric pressure into the bottle

瓶子吞鸡蛋的实验作文600字
答：在日常生活或是工作学习中，大家都有写作文的经历，对作文很是熟悉吧，根据写作命题的特点，作文可以分为命题作文和非命题作文。那要怎么写好作文呢？以下是我精心整理的瓶子吞鸡蛋的实验作文600字，希望能够帮助到大家。什么...

瓶吞鸡蛋实验过程及原理
答：瓶吞鸡蛋实验过程及原理：燃烧的餐巾纸用掉瓶子里所有的氧气，瓶外的空气压力比瓶内的空气压力就大，瓶外强大的压力把鸡蛋挤压进了瓶中。鸡蛋比瓶口大，却能掉进瓶子里，因此发生了弹性形变。由于鸡蛋处在大气压中，必然...

瓶子吃鸡蛋的实验过程
答：瓶子吃鸡蛋的实验过程如下：1、鸡蛋放于空瓶子旁边，以备实验过程中，能快速把鸡蛋放于瓶子上方。2、拿一张厚一点的纸张，把纸张点亮后快速放进瓶内。提示：纸张要厚一点，这样下面的步骤中点燃它时才不会燃烧得太快。3...

瓶子吞鸡蛋实验的原理
答：瓶子吞鸡蛋实验的原理是利用了空气压力的差异。资料扩展：空气压力（又称空气压强）指空气垂直作用在空气微团表面或物体表面单位面积上的力，单位为帕（Pa）。地球的周围有一层空气——大气。空气的分子非常活跃，由于地球具有...

小实验《瓶中的鸡蛋》启示
答：《瓶吞鸡蛋的秘密》教学反思 这一节主要的目的是研究大气的压力。因此我首先让学生观看瓶吞鸡蛋的视频和我的演示。学生看到这种现象很容易就会猜测，这是什么原因导致的？并且他们对于这种现象，进行自己的猜想。在猜想的时候...

瓶口“吞”鸡蛋
答：小瓶口能把打鸡蛋吞进“肚子”里去？这怎么可能？可在一本《小百科》上，我就看到有这样一个小实验，所以，我就特别想动手试试看。我先选了两个鸡蛋让妈妈放到小锅里煮着，然后，去院里找了一个营养快线的空瓶子洗...

鸡蛋能放进瓶子里的奥秘的作文
答：上课铃声响了,老师走进教室,说:“今天我们来探索下科学的奥秘,上一节实验课。”同学们听后都高兴地欢呼了起来,然后老师给我们讲解了实验过程,并告诉我们这个实验的名字叫瓶吞鸡蛋,说完同学们有七嘴八舌的议论了起来,瓶子...

瓶子吞鸡蛋的原理
答：原理：瓶子内压小，外压大，是空气将鸡蛋压入瓶内的。先将瓶子内空气加热（增加压力），然后迅速在瓶口放上鸡蛋，待瓶内温度降低（压力减小时），鸡蛋就自动入瓶了。步骤：把熟鸡蛋壳剥掉；将纸片撕成长条状；将点燃的...

瓶子吞鸡蛋
答：原来火柴燃尽了瓶子里所有的氧气,瓶中的空气压力比瓶外的空气压力大,瓶外强大的压 力把鸡蛋“吞”进去了。因此,我们叫这种实验为“瓶子‘吞’鸡蛋”。 原来,一个小小的实验,竟包含了这么多的学问。生活中,我还要继续寻找更多的科学...
