“ bites bell bell ” attended class, there is a packet of an unripe egg, salt in Mr. Chen hand, one burns bosom and a transparent vitreous club, smilingly ground went. We feel very strange. Some people say: “ should Mr. Chen eat an egg to us? Some ” people say: “ reckons Mr. Chen wants to become magic to us. ” I burst out laughing, say: “ is possible. Mr. ” Mr. Chen heard, uncannily laugh says: What you say “ is incorrect, we should do a test that allows egg float to rise today. ”

“叮铃铃”上课了,陈老师手里拿着一个生鸡蛋、一包盐、一个烧怀和一根透明的玻璃棒,笑眯眯地走了进来。我们都觉得很奇怪。有的人说:“难道陈老师要给我们吃鸡蛋吗?”有的人说:“估计陈老师要给我们变魔术。”我哈哈大笑起来,说:“有可能。”陈老师听见了,神秘地笑了笑说:“你们说的都不对,我们今天要做一个让鸡蛋浮起来的实验。”

Who comes to “ does side teacher conceive water partly? ”“ I! Me! ” classmate learns people raise one's hand of ground of strive to be the first, the teacher chose Hu Zhonghu. Rapid ground is taking Hu Zhonghu to burn a bosom to run to side place, received half bosom water, next, rapid ground runnings, burn a bosom to hand teacher.

“谁来帮老师倒半怀水?”“我!我!”同学学们争先恐后地举手,老师选了胡钟虎。胡钟虎飞快地拿着烧怀跑到侧所,接了半怀水,然后,飞快地跑回来,把烧怀递给老师。

I want “ now do a test. Mr. ” say. One's voice in speech just fell, the teacher takes care the egg the ground puts Ji Jiji to burn a bosom in. See the egg sank slowly only, resemble a diver, jump into water, skip, still can not swim finally, resemble instead by grip like.

“现在我要做实验了。”老师说道。话音刚落,老师就把鸡蛋小心冀冀冀地放进烧怀里。只见鸡蛋慢慢沉了下去,像一个跳水运动员,跳进了水里,蹦了蹦,可最终还是没有游上来,反而像被吸住了似的。

Next, mr. Chen put dot salt in the cup, let Yang Chen take vitreous marvellous mix. But agitate a long time, egg still absolutely still, still be conscientiously ground sleeps in cup bottom. Waited a long time, we do not have patience, aloud says: “ put so much salt, the egg still rises without float, the teacher is deceiving people for certain. Mr. ” seemed to see our doubt, smilingly ground says: “ egg won't sleep all the time, you valued you! ” our pop eye, the teacher takes out a bit salt again, put into burn a bosom in, let Yang Chen continue agitate, this egg unexpectedly slowly float rose. We cry rise: “ egg float rose! ”

然后,陈老师在杯子里放了点盐,让杨晨拿玻璃棒搅。可搅拌了半天,鸡蛋仍纹丝不动,还是老老实实地在杯底睡觉。等了半天,我们都没耐心了,大声地说:“放了这么多盐,鸡蛋还是没有浮起来,老师肯定在骗人。”老师好像看出了我们的疑惑,笑眯眯地说:“鸡蛋不会一直睡觉哦,你们看好你们看好了!”我们瞪大了眼睛,老师又拿出一点盐,放进烧怀里,让杨晨继续搅,这次鸡蛋居然慢慢浮起来了。我们大叫起来:“鸡蛋浮起来了!”

This experiment let us understand a principle: At the beginning the gravity that the egg is less than oneself by the flotage of water, sank so, sank, after joining salt, clear water became salt solution, briny density is gotten greatly than clear water much, come so, the flotage that the egg gets also greatens subsequently, so the egg rose with respect to float.

这次实验让我们明白了一个原理:一开始鸡蛋受到水的浮力小于自身的重力,所以就下沉了,沉了,加入盐之后,清水变成了盐水,盐水的密度比清水大得多,这样一来,鸡蛋受到的浮力也就随之变大,所以鸡蛋就浮起来了。

The scientific nowhere in the life is absent, science results from the life, as long as we are diligent at dug, can discover a lot of scientific fun.

生活中的科学无处不在,科学源于生活,只要我们勤于探究,就会发现很多科学趣事。

Hu Jialin

“ Ding Ling 0 “ attended class, ground of Mr. Chen stride walks into a classroom, see Mr. Chen skill is taking egg and a packet of salt only, another hand is taking a beaker and club of a glass. I think: Is Mr. Chen to want to boil an egg to eat to us? Taking doubt, ground of our fix eyes on is staring at the every act of Mr. Chen. Mr. Chen face takes a smile to say: We come to “ today do the test that allows egg float to rise. ”

“丁零零“上课了,陈老师大步流星地走进教室,只见陈老师一手拿着鸡蛋和一包盐,另一手拿着一个烧杯和一根玻璃棒。我想:陈老师是要给我们煮鸡蛋吃吗?带着疑惑,我们目不转睛地盯着陈老师的一举一动。陈老师面带一丝笑容说:“今天我们来做让鸡蛋浮起来的实验。”

Mr. Chen lets Hu Zhonghu received half cups of water first, took an egg cautiously then, put into water slowly. Composition / I think: The egg is sure float does not rise. As expected, mr. Chen one let go, the egg sank, shook a few times, also did not move easily, copy figure of Buddha is lodestone of a circle, by cup of firmly ground grip, as if again lazy like baby, breathe out in cup bottom breathe out the ground sleeps to become aware greatly.

陈老师先让胡钟虎去接了半杯水,接着小心翼翼地拿起了鸡蛋,慢慢地放进水里。作文/我想:鸡蛋肯定浮不起来。果然,陈老师一松手,鸡蛋就沉了下去,摇晃了几下,就一动也不动了,仿佛像是一块圆形吸铁石,牢牢地吸住杯底,又仿佛像一个懒娃娃,在杯底呼呼地睡大觉。

Mr. Chen is then clear clear the throat, say: “ next, I should use a magical glamour, let egg float rise. Is ”“ egg OK really does float rise? ” we are half believing and half doubting the ground is looking at Mr. Chen. At this moment, mr. Chen got on Yang Chen please stage, tear apart the bag that pack next, caught a small salt to be put into water, let Yang Chen agitate. It is good to can mix a little while, the egg remains the same absolutely still ground lies over to sleep to become aware greatly, I sighed at a heat, say: “ alas, failed. ” some people also do not have patience, pulling voice to say: “ egg rises without float, the teacher deceives people! Mr. ” Mr. Chen does not no hurry unbearably however ground say: “ is not urgent, not urgent. ” sees only, mr. Chen caught a big salt to be put into water again, next, let Yang Chen continue again agitate. Mixed for ages again, salt melted slowly, egg gradually float rise. “ is too marvellous! Too marvellous! Egg eventually float rose. We are saying ” singularly, look at, it is in the heart excited.

接着陈老师清了清嗓子,说:“接下来,我要用一个神奇的魔法,让鸡蛋浮起来。”“鸡蛋真的可以浮起来吗?”我们将信将疑地望着陈老师。这时,陈老师把杨晨请上了台,然后撕开包装袋,抓了一小把盐放进水里,让杨晨搅拌。可拌了好一会儿,鸡蛋仍旧纹丝不动地躺在那儿睡大觉,我叹了一口气,说:“唉,失败了。”有些人也没耐心了,扯着嗓子说:“鸡蛋没有浮起来,老师骗人!”陈老师却不慌不忙地说道:“不急,不急。”只见,陈老师又抓了一大把盐放进水里,然后,又让杨晨继续搅拌。又拌了好久,盐慢慢融化了,鸡蛋渐渐浮了起来。“太棒了!太棒了!鸡蛋终于浮了起来了。”我们不可思议地说着,看着,心里都是一片激动。

Pass Mr. Chen explain, we knew the principle of this experiment, ha, let me tell you! Because the density of the egg is bigger than clear water,that is much, after adding a lot of salt, clear water became salt solution, briny density is gotten greatly than clear water again much, so, egg ability float rise.

通过陈老师的讲解,我们知道了这个实验的原理,哈哈,让我来告诉你吧!那是因为鸡蛋的密度比清水大得多,加了许多盐之后,清水就变成了盐水,盐水的密度又比清水大得多,所以,鸡蛋才浮了起来的。

Be closely bound up of a few things in living scientificly with us, want us to take care observation only, with respect to meeting discovery, science is beside us.

科学与我们生活中一些事情息息相关,只要我们留心观察,就会发现,科学就在我们身边。

【篇三:鸡蛋浮起来的实验作文三年级】

Chen Yuhan

“ Ding Ling 0 ” attend class ring rang, mr. Chen went mysteriously. See she is taking a flaxen egg single-handed only, taking transparent beaker single-handed, the glass that there still are a packet of salt and a slightness inside is marvellous. My heart thinks: should Mr. Chen let us establish an egg again? I am staring at Mr. Chen with amazed look.

“丁零零”上课铃声响了,陈老师神神秘秘地走了进来。只见她一手拿着一个淡黄色的鸡蛋,一手拿着透明的烧杯,里面还装着一包盐和一根细长的玻璃棒。我心想:难道陈老师又要让我们立鸡蛋了?我用惊奇的目光盯着陈老师。

Mr. Chen is on dais, put the egg cautiously on dais, also put other stuff one by one again next above. Immediately, the blast in the classroom opened boiler, everybody you my one language comment opened one talk: Some saying: What should Mr. “ Mr. Chen do? ” some says: “ wow oh! Mr. Chen should want to do little test to us! ” returns some saying: Estimation of Mr. “ Mr. Chen should cook an egg to us. ”

陈老师走上讲台,把鸡蛋小心翼翼地放在讲台上,然后再把其它材料也一一摆放在上面。顿时,教室里炸开了锅,大家你一言我一语议论开了:有的说:“陈老师要干什么呀?”有的说:“哇哦!陈老师应该要给我们做小实验啦!”还有的说:“陈老师估计要给我们煮鸡蛋了。”

Mr. Chen uses eye fling a week, next clear clear the throat say: Teacher of “ whose side receives a cup of water? We should do a test today, let an egg rise in the float in water namely. Ground of strive to be the first raises ” classmates the hand comes, mr. Chen lets Hu Zhonghu received a cup of clear water.

陈老师用眼睛扫视了一周,然后清了清嗓子说:“谁帮老师接杯水?今天我们要做一个实验,就是让鸡蛋在水里浮起来。”同学们争先恐后地举起手来,陈老师让胡钟虎去接了一杯清水。

Mr. Chen takes an egg, put gently into beaker, loosened slowly next hand. The egg sinks slowly a cup of bottom, shook twice, lie motionlessly over next, with respect to the little baby that sleeps soundly like. Everybody comments again: Some saying: How doesn't “ egg have float to rise? ” some says: “ egg meets what float rises, meet what float rises certainly! ” classmates comment at the same time, at the same time the egg that ground of quiet energy of life of fix eyes on, wirh fixed attention is staring at dais to go up.

陈老师拿起鸡蛋,轻轻地放入烧杯中,然后慢慢地松开了手。鸡蛋便慢慢地沉到杯底,晃了两下,然后一动不动地躺在那里,就像一个熟睡的小娃娃。大家又议论开了:有的说:“鸡蛋怎么没浮起来呢?”有的说:“鸡蛋会浮起来的,一定会浮起来的!”同学们一边议论,一边目不转睛、凝神静气地盯着讲台上的鸡蛋。

Mr. Chen asks Yang Chen to help again, oneself are gone to by salt is added in beaker. Yang Chen takes vitreous club gently agitate, but agitate a long time, the egg still sinks in place absolutely still. How doesn't “ have float to rise? Is the teacher deceiving people? ” some classmates had done not have patience. “ classmates are not anxious! Mr. ” Mr. Chen is placed place a hand to say, put dot salt in the cup again next. Yang Chen agitate a little while, see an egg only slowly float rise. “ ! Egg unexpectedly float rose, too magical! ” everybody cries rise. Mr. Chen sees everybody's excited look, smilingly ground says: What principle is you know “ ? Tell you, because liquid density is bigger,that is, buoyancy is bigger, clear water density is smaller, buoyancy is small also, after joining salt, solution density increases a club, the egg with changeless weight rises to surface. ”

陈老师又请杨晨帮忙,自己在旁边往烧杯里加盐。杨晨拿起玻璃棒轻轻搅拌,可搅了半天,鸡蛋仍旧沉在原地纹丝不动。“怎么没浮起来?老师是不是在骗人?”有些同学已经没耐心了。“同学们不要着急!”陈老师摆摆手说,然后又在杯子里放了点盐。杨晨又搅拌了一会儿,只见鸡蛋慢慢地浮了起来。“哇!鸡蛋居然浮起来了,太神奇了!”大家大叫起来。陈老师看见大家激动的样子,笑眯眯地说:“你们知道是什么原理吗?告诉你们吧,那是因为液体密度越大,浮力就越大,清水密度越小,浮力也就小了,加入食盐后,溶液密度加大棒,重量不变的鸡蛋浮出水面。”

Be too interesting really, pass this test, I discover science and life are linked together cheek by jowl, after coming home, I must continue my scientific test.

真是太有趣了,通过这个实验,我发现科学与生活紧密相连,回家后我一定要继续我的科学实验。
