1、实验的乐趣-实验作文600字

我的博士舅舅常说:“从实验中感悟出的大道理,可以是方法上的,也可以是精神上的。做一个小实验,明白一个大道理,这就是实验的乐趣所在。”

My doctoral uncle often says: "The avenue of the avenue from the experiment can be method or spiritual. Do a small experiment and understand a big truth. This is the joy of experiments."

有一次,我去舅舅家度假,舅舅给我和弟弟准备了许多有趣的实验材料。我们挑选了一个有关结晶的实验——“会生长的彩色圣诞树”。我们首先把印有圣诞树图案的纸板固定在一个底盘上,再将液体包内的无机盐溶液从圣诞树的顶部小心翼翼地往下淋,然后按说明书的要求静静等待10个小时。从说明书上得知:水会在毛细作用下迅速蒸发,而附着在纸板上的白色无机盐晶体将慢慢析出形成漂亮的结晶。我们很好奇,迫不及待地想看到这神奇的一幕。

Once, I went to my uncle's house for vacation, and I prepared a lot of interesting experimental materials for me and my brother.We chose an experiment on crystals- "growing colorful Christmas trees".We first fix the cardboard with a Christmas tree pattern on a chassis, and then pour the inorganic salt solution in the liquid bag from the top of the Christmas tree, and then wait for 10 hours according to the requirements of the instructions.It is learned from the instructions that the water will evaporate quickly under the cap action, and the white inorganic salt crystal attached to the cardboard will slowly precipitate the formation of beautiful crystals.We are curious and can't wait to see this magical scene.

弟弟还小,不知道10个小时有多久,以为等一等就到了。于是每过五、六分钟,就拉着我跑去看圣诞树,结果一点儿变化也没有。就这样来回跑了七、八次,我们有点不耐烦了,冲着大伙嚷:“这是什么破实验呀,圣诞树老半天都没有出来。等得我们都不耐烦了!”舅舅听见了,和颜悦色地对我们说:“做事要学会等待,不要心烦急躁。既然你们已经按步骤完成了实验的所有工作,就要对自己有信心,干嘛不用上统筹学、利用等待的时间去做些别的事情呢?”我们想了想,觉得有道理。

My brother is still young, I don't know how long for 10 hours, I think it will be here.So every five or six minutes, I pulled me to watch the Christmas tree, but there was no change at all.I ran back and forth seven or eight times in this way. We were a little impatient. We shouted: "What is this broken experiment? The Christmas tree has not come out for a long time. We are impatient!"The land said to us: "You need to learn to wait for things, don't be upset. Since you have completed all the work of the experiment according to the steps, you must have confidence in yourself.What about things? "We thought for a while, and it made sense.

接下来的几个小时里,我和弟弟又做了“彩虹雨”、“冒泡的岩浆瓶”等实验,每一个小实验都让我们兴奋不已。不知不觉地,居然把圣诞树的事给忘了,吃了晚饭后才想起来。此时,圣诞树已经长出了结晶,五彩缤纷,美丽极了,可把我和表弟高兴坏了。

In the next hours, my brother and I and I did experiments such as "Rainbow Rain" and "bubble magma bottle". Every small experiment made us excited.Unconsciously, I forgot about the Christmas tree, and I remembered it after dinner.At this time, the Christmas tree has grown crystals, colorful, beautiful, but I am happy to make me and my cousin.

看着绚烂多彩的圣诞树,我明白了,实验中真的有大道理:做事除了专注,还要学会等待,要有耐心和信心,这正如居里夫人所说的“人必须要有耐心,特别是要有信心”;同时,统筹学也开始在我心里生根等待发芽呢!

Looking at the gorgeous Christmas tree, I understand that there is really a reason in the experiment: in addition to focusing on things, we must also learn to wait, and be patient and confident."It is necessary to have confidence"; at the same time, the overall studies have begun to take root in my heart and wait for germination!

2、享受实验的乐趣-写事作文550字

小时候,我在家与小伙伴们一起做过许多实验,让我们尽享解开谜团后的乐趣。

When I was a kid, I have done many experiments with my friends at home, so that we can enjoy the fun after solving the mystery.

有一天,我的好朋友神秘地指了一张照片给我们看,是一个人躺在水面上看书,问:“这个人为什么没有沉下去?”“因为他有超能力。”“因为他下面有人托着。”而我则说:“这是死海,里面含盐超过30%,所以浮了起来。”

One day, my good friend mysteriously pointed to a photo for us. It was a person who was lying on the water and read a book, asking, "Why didn't this person sink?" "Because he has super power." "Because of him belowSomeone entrusts it. "And I said:" This is the sea of death, which contains more than 30%of the salt, so it floats. "

为了证明我的话,又做了一次实验。我们首先拿来一个玻璃钢,往里面倒了半缸水,把生鸡蛋放入水中,鸡蛋马上沉了下去。我又买来了一包盐和一个勺子,往水里加了几勺盐,鸡蛋没动。我弟说:“搅一下,让盐融化。”我搅了搅,伙伴们睁大眼睛看着,我也默默念道:快浮起来呀!快!可未能如我所愿,我又加了几勺,并用勺子使劲的搅,缸里水浑浊了。鸡蛋居然浮在了水中,正当我们准备欢呼时,鸡蛋又落了下去,原来是勺子把他搅起来的。有一个伙伴皱着眉头,手撑着头,眼睛直勾勾的盯着水缸,突然说:“干脆把盐都倒进去吧!”我听了连忙都倒了进去。时间一点点流逝,我们一直盯着水缸看,盐慢慢沉了下去,鸡蛋没浮起来。我失望的想:怎么会呢?不可能呀!突然我又恍然大悟,拿起了勺子搅拌了几下,鸡蛋一点点浮了上来,我们的心也一点点悬了起来,直到最后鸡蛋浮出了水面,我们欢呼了起来,因为鸡蛋用手按下去也还会浮起来。

To prove me, I did another experiment. We first brought a glass reinforcement, poured half a cylinder of water in it, put the raw eggs in the water, and the eggs sank immediately. I bought another pack of salt and a spoon, adding a few spoons of salt to the water, and the eggs didn't move. My brother said, "Stir, let the salt melt." I stirred it, my partners opened their eyes wide, and I also silently read: Fill up! Fast! But I can’t be as my wishes, I will add it again After a few spoons, and stirred it with a spoon, the water in the tank was turbid. Eggs actually floated in the water. When we were about to cheer, the eggs fell again. It turned out that the spoon stirred him. A partner frowned, holding his head, staring at the water tank straight, and suddenly said, "Just pour all the salt in!" I poured them in quickly. Time passed a little bit, we kept staring at the water tank, salt slowly sank, and the eggs did not float. I was disappointed: How could it be? Impossible! Suddenly I realized it again, picked up the spoon and stirred it a few times, the eggs floated a little bit, and our hearts hung up a little, until the end of the egg turned out to the egg, the eggs emerged until the eggs emerged. On the water, we cheered, because the eggs pressed with their hands and would float.

人生短暂要学会享受生活中那些给你带来的惊喜。这一次实验就给我带来了乐趣。

Life is briefly learned to enjoy the surprises brought to you in life.This experiment brought me fun.

小学生周记450字篇二_我爱读书

Primary School Student Weekly 450 Words 2_I Love to Read

高尔基曾经说:“书是人类进步的阶梯”。毛泽东也说过:“饭可以一日不吃,觉可以一日不睡,书不可以一日不读”。我的生活也离不开书的滋养。

Gorky once said: "Books are the stairs of human progress."Mao Zedong also said: "The rice can not be eaten for a day, I feel that I can not sleep for a day, and the book cannot be read for a day."My life is also inseparable from the nourishment of books.

有一天早晨,我发现楼下摆了一个书摊,便和妈妈商量让我下去买书。站在书摊旁,各种各样的书呈现在眼前,我看看这,看看那,终于选上一本科幻小说——《查理九世》。我抱着书回到家里,不一会儿我就沉浸于书中,就像书虫一样把其中的知识一点一点地吞进肚子。书中一篇篇生动的文章像酒一样把我弄得半醉半醒。

One morning, I found a book stall under the downstairs, so I discussed with my mother to let me go to buy a book.Standing next to the book stall, all kinds of books were presented in front of me. I looked at it and looked at it. Finally, I chose a science fiction novel- "Charles 9".I held the book back home, and after a while I was immersed in the book, like a bookworm, swallowing the knowledge little by little.The vivid articles in the book make me half drunk like wine.

妈妈做好了饭菜,正等着我吃饭。妈妈一看我没什么动静说:“奇奇!快点吃饭来。”我这才慢吞吞地拿着书在餐桌前坐下。我一手拿着筷子另一手拿着书,开始了边吃饭边看书。我向一块胡萝卜夹去,此时正是书中内容高潮时刻,我心里非常紧张,就在这时感觉鼻子有些难受。我放下书就发现我夹得那块胡萝卜丁居然在我的鼻子里。妈妈大笑起来:“让你在吃饭时看书,你看进鼻子里了吧!”

My mother was ready to eat and was waiting for me to eat.When my mother saw that I had nothing to do with it, "Qiqi! Hurry up to eat." I slowly took the book and sat down in front of the table.I held the chopsticks with the other hand in my hand and started reading while eating.I was pinched to a carrot. At this time, the content of the book was climax. I was very nervous, and at this moment I felt a little uncomfortable.When I put down the book, I found that I caught the carrot diced in my nose.Mom laughed: "Let you read a book while eating, you have read it in your nose!"

书是我的良师益友,带给我快乐,书籍可以给我们带来收获,使我们进步。我爱读书。

The book is my good teacher and friend. It brings me happiness. The books can bring us gains and make us progress.I love reading.

4、有趣的实验_寒假趣事日记200字

今天,我想做一个小小的实验,这个实验可神奇了,我一直都想做这个实验。这个实验的第一步是先拿一个放大镜和一张白纸,然后用铅笔涂上一块黑色接着在猛烈太阳的照射下,就可以做这个实验了。

Today, I want to do a small experiment. This experiment is amazing. I always want to do this experiment.The first step of this experiment is to take a magnifying glass and a piece of white paper, and then apply a piece of black with a pencil and then under the irradiation of the violent sun to do this experiment.

我把放大镜放在太阳底下,照在白纸的黑块上会出现一颗小小的亮点,我仔细的观察,慢慢的,我发现白纸上的那个亮点开始冒烟了,我小心的移动那个亮点,结果,白纸被燃烧出了一个洞,太神奇了。

I put the magnifying glass under the sun, and a small highlight will appear on the black block of the white paper. I carefully observe and slowly, I found that the highlight on the white paper began to smoke.Move that highlight, as a result, the white paper was burned out of a hole, which was amazing.

朋友们,你们知道里面有什么奥秘吗?仔细想想吧。

Friends, do you know what mysteries are there?Think about it.

5、有趣的发现_科学小实验作文400字

作文刚一开始,老师满脸笑容地走进教室,手里拿着一打纸。这时,同学们很好奇,老师拿来这么一打纸来干什么呢?我们都带作文本了。

At the beginning of the composition, the teacher walked into the classroom with a smile, holding a dozen paper in his hand.At this time, the classmates were curious. What did the teacher do such a dozen paper?We are all brought as text.

老师说:“今天我们要做一个非常有意思的游戏。”同学们认为很奇怪,用纸怎么能做游戏呢?只见老师用双手分别夹住两张相同的信纸,放在嘴边。老师说:“你们猜一猜,我用力在纸中间吹一口气,纸会怎么样?”大家议论纷纷,有的说:“当然会往两边飞了。”还有的人说:“这还用猜啊,很明显是往两边飞了。”于是老师吸了一口气,然后猛地一吹,纸却合在了一起。老师看到大家疑惑不解的样子,说:“同学们可以自己试一试。”同学们拿起纸,按照老师的样子一吹,纸真的向中间飞去。同学们带着疑问去问老师,老师说:“在我们周围充满了空气,空气是有压力的,当我们用力向两张纸中间吹气时,空气被吹走了,压力也变小了,而纸外的压力不变,会向中间挤压,所以两张纸会粘在一起了。”

The teacher said, "Today we are going to make a very interesting game." The classmates thought it was strange. How could I make a game with paper?I saw the teacher clamped two of the same letter paper with both hands and placed it on his mouth.The teacher said, "Guess, I guess, I blow a breath in the middle of the paper, what will happen to the paper?" Everyone talked, and some said, "Of course, it will fly to both sides." Other people said, "Guess, it is obviously flying to both sides. "So the teacher took a breath, then blowing sharply, but the paper was together.The teacher saw everyone puzzled, and said, "Students can try it by themselves." The students picked up the paper and blown according to the teacher, and the paper really flew to the middle.The classmates asked the teacher with doubts. The teacher said: "It is full of air around us, and the air is stressful. When we blow the air in the middle of the two pieces of paper, the air is blown away, and the pressure becomes smaller. The pressure becomes smaller.The pressure outside the paper remains unchanged and will squeeze to the middle, so the two pieces of paper will stick together. "

通过这次有趣的发现,我懂得了生活中有许多看似简单的事情,只有通过实践才能发现它。

Through this interesting discovery, I understand that there are many seemingly simple things in life, and only through practice can it be discovered.

6、有趣的小陀螺_科学小实验作文500字

前几天,老师让我们做会变色的陀螺。

A few days ago, the teacher asked us to make a discolored gyroscope.

我们回到家,准备好材料:厚纸板、彩笔、圆规、铅笔、赤字、剪刀、中性笔芯。按老师说的方法做来起来(我):从装蛋糕的纸箱上剪下了厚纸板,然后用圆规在上面画了个圆,接着用剪刀剪下这个圆,再把圆分成了八份,然后再每一份涂上一种颜色,最后用剪刀向圆的中心桶了一个洞,用中性笔芯插入洞内。这样,一个会变色的陀螺做好了!

We return home and prepare the materials: thick cardboard, color pen, round rules, pencils, deficits, scissors, neutral pen cores.Come up according to the method said by the teacher (I): Cut the thick cardboard from the carton of the cake, then draw a circle on it with a circle, then cut this circle with scissors, and then divide the circle into eight copies, and then divide the circle into eight portions.Then apply a color in each part, and finally use the scissors to a hole in the center of the circle, insert it into the hole with a neutral pen.In this way, a colorful gyroscope is ready!

转一转试试?哇,居然是彩色的!有淡黄、粉色、橘红、墨兰。转了多次,我发现淡黄是由黄白、橘黄组成;粉红是由淡紫转起来速度快变成;橘红是由橘黄和红组成;墨兰是由蓝、铅笔黑和中性笔黑组成。多么美丽呀!

Try it?Wow, it is actually colorful!There are pale yellow, pink, orange, and Mulan.After turning many times, I found that light yellow is composed of yellow and white and orange; pink changes from the fastest speed of light purple; orange red is composed of orange and red;EssenceWhat a beautiful!

到了学校,老师问转起来是什么颜色?大家齐声说:“白色!”我突然愣了一下,很奇怪:“你们都是白色,为什么我是彩色?”我回到家又试着转了一次,速度比原来快多了!颜色居然也变了,变成了白色!哦,我明白了,速度越快颜色就会变淡。

When I was at school, the teacher asked what color turned around?Everyone said in unison: "White!" I suddenly stunned, very strange: "You are all white, why are I color?" I tried to turn home again when I got home, which was much faster than the original!The color actually changed, and it became white!Oh, I understand, the faster the speed will fade.

突然,我想起一休的扇子,才恍然大悟。原来速度越快,“他们”就会留下影子,所有影子的颜色合在一起就会变成白色。这也是动画片的原理,我又上网查了查资料,果然是这样。

Suddenly, I remembered the fan of a break, and I realized it suddenly.The faster the speed, the "they" will leave a shadow, and the colors of all shadows will become white.This is also the principle of cartoons. I checked the information online again.

科学真有趣,原来玩也能学到知识!

Science is really interesting, and you can learn knowledge!

(后记:太阳光是由七种颜色组成的,如果按七种光的色彩和比例涂在纸片上,当陀螺旋转起来时,由于人眼有视觉暂留现象,在视网膜上七种颜色的光叠加就引起白色的视觉,所有彩色陀螺旋转起来就变成了白色。)

(Post -record: Sunlight is composed of seven colors. If the color and proportion of seven light are applied to the paper piece, when the gyroscope is rotated, because the human eye has a visual retaining phenomenon, the seven colors of light on the retina are on the retina.The superposition causes white vision, and all the color gyroscopy turns into white.)

7、有趣的国庆节_科学小实验作文600字

在十月三日的上午,我去表哥家玩。过了一会儿,表哥问我说:“如果有一个球,外面的一半是木头做的,里面的一半是玻璃的。把它放在水里,是沉下去?还是浮在水面上?”“我认为是沉下去!”他补充道。

On the morning of October 3, I went to my cousin's house to play.After a while, my cousin asked me, "If there is a ball, half of the outside is made of wood, and half of the inside is glass. Put it in the water, sink?I think it is sinking! "He added.

回家的路上,我绞尽脑汁,努力地思考:“是通过木头的浮力浮起来呢?还是具有玻璃的特性沉下去呢?”那就做一场实验吧。

On the way home, I racked my brains and tried hard: "Is it floating through the buoyancy of the wood? Or is it sinking with the characteristics of glass?" Then do an experiment.

我来到家中,找到了一个木球,又找到了一个小玻璃球,把木球削到和玻璃球一般大小,再切开,把玻璃球装进去,实验材料就好了。接着我又把水盆设为了实验场地,实验就准备好了。

I came home, found a wooden ball, and found a small glass ball, cut the wooden ball to the size of the glass ball, cut it, and then put the glass ball in. The experimental materials were fine.Then I set the water basin as the experimental venue, and the experiments were ready.

我把水盆装满水,放在客厅的地板上。“三、二、一”我数着数,把小球丢进了水盆里。沉下?浮起?我紧张地等着水面平静。难道真的像表哥说的那样吗?待水平静时,我仔细观察,小球虽然没有露在水面上,但是也没有沉到底下。我又试验了几次,球还是浮在水中,丝毫没有沉下去的样子。第二天,我在电话里兴奋地对他说:“表哥,你昨天说的不对。我试验了一下,那个小球根本没有沉下去,你可以来我家参观一下!”过了几分钟,表哥便来到了我家,他惊奇地看完了我的实验,自己又试了几次。“我的一个朋友告诉我这个问题,并说球一定会沉!”他说道,“看来他也有判断失误的时候,我这就告诉他去!”我听完了他的话后十分高兴。

I filled the water basin with water and placed on the floor of the living room."Three, two, one" I counted and threw the ball into the basin.Sink down?Floating?I was waiting nervously for the calm surface.Is it really as what cousin said?When the level was quiet, I observed it carefully. Although the ball was not exposed to the water, it did not sink to it.I tested a few more times, the ball was still floating in the water, and it didn't sink at all.The next day, I said to him excitedly on the phone, "Cousin, what you said yesterday. I tested it. The little ball didn't sink at all, you can come to my house to visit!" After a few minutes,My cousin came to my house. He looked at my experiment in surprise and tried it a few more times."One of my friends told me this question and said that the ball would be sinking!" He said, "It seems that he also told him when he also made a mistake!" I was very happy after he heard his words.

在以前,就像伽利略在比萨斜塔上证明亚里士多德的错误一样,都说明了一个道理:在探索科学、学习知识时,不能一味地依赖书本、老师,他们说的可以参考,但绝对不能当真理来学,要自己动手试一试,才能得到真实可靠的知识。

In the past, just like Galileo's error on Aristotle on the Pizza Tower, it explained the truth: when exploring science and learning knowledge, you cannot blindly rely on books and teachers.You must not learn to be a truth, and you must try it by yourself to get true and reliable knowledge.

8、一个有趣的小实验_小学写事作文300字

“烧不坏的手帕!”多新鲜,哪有烧不坏的手帕?我决定亲自动手试试。

"Burn the handkerchief!" How fresh, how can there be a bad handkerchief?I decided to try it by myself.

实验开始了。我先把酒精倒入量杯里,接着我用镊子夹住手帕,放进装有酒精的量杯里,浸湿浸透,用镊子捞上来,抖一抖。左手拿着打火机,把酒精灯点燃。然后,把手帕放在酒精灯上烧,“刷”的一下,火苗从手帕上窜了一下,燃起了熊熊大火。我紧张极了,手也在抖。我用最快的速度把手帕扔在脸盆了。心想:这下可闯祸了,手帕一定被烧出个大洞。我把手帕从脸盆了拿出了,挤干,展开一看。啊!奇迹发生了,手帕居然没有被烧坏。这为为什么?我连忙查找资料,一看,才恍然大悟。原来手帕中含有酒精和水,着火时,燃烧的是酒精,所以手帕烧不坏。如果让它继续燃烧,酒精烧尽了,手帕就要烧着了。

The experiment started.I first poured the alcohol into the cup, and then I clamped the handkerchief with a mule, put it in a measuring cup with alcohol, soaked and soaked, fished up with a mule, shaking.Hold the lighter with your left hand and ignite the alcohol lamp.Then, put the handkerchief on the alcohol lamp and burned, "brush", the flames rushed from the handkerchief, burning the fire.I was so nervous that my hands were shaking.I threw the handkerchief in the washbasin at the fastest speed.I thought: This time, it can be caused, and the handkerchief must be burned out of a large hole.I took the handkerchief out of the washbasin, squeezed it, and looked at it.what!The miracle happened, and the handkerchief was not burned out.Why is this?I quickly searched the information, and I realized it at a glance.It turned out that the handkerchief contained alcohol and water. When it was on fire, it burned alcohol, so the handkerchief was not bad.If it keeps burning and the alcohol is burned, the handkerchief will be burned.

这个小实验真有趣!

This small experiment is really interesting!

9、童年的一次有趣的实验

听说蚂蚁有超强的记忆力,所以我想做个实验,测试一下。

I heard that the ants have a strong memory, so I want to do an experiment and test it.

一天早晨,我来到长乐公园的小山丘上,发现了一个蚂蚁窝。正好有一群蚂蚁正在往出爬。我就跟着他们走了五米路,用一个瓶子把他们全抓了起来。接着,我把蚂蚁爬过的地方留下的气味用水冲掉,喷上别的气味。然后,我用铁锹挖两排小洞,摘一些树枝插在小洞里。接下来,我再拿报纸铺在两排小树枝中间的地上,揪一把树叶,洒在上面。这样我就把环境完全改变了。

One morning, I came to the hills in Changle Park and found an ant nest.It happened that there was a group of ants going out.I followed them for five meters and grabbed them with a bottle.Then, the smell left the ants where the ant crawled over with water and sprayed with other odors.Then, I dug two rows of small holes with iron crickets and picked some branches and inserted them in small holes.Next, I paved the newspaper on the ground in the middle of the two rows of small branches, scratched a leaf, and sprinkled it on it.In this way, I completely changed the environment.

我在离蚂蚁窝五米远的报纸一端,轻轻的打开瓶盖,蚂蚁们争先恐后地爬了出来。我赶紧抓住这个机会,在它们身上刷了黄色颜料。我看到他们在报纸一端犹豫了好一会儿,小心翼翼地爬了上去。有几只大胆的蚂蚁快速爬到了前面,一只胆子更大的蚂蚁爬进了树叶里面。他在里面停了好一会儿才出来,看上去很害怕的样子。

At one end of the newspaper at the Ant Nest, I opened the bottle cap gently, and the ants crawled out.I quickly seized this opportunity and brushed yellow paint on them.I saw them hesitated for a while, and climbed it carefully.Several bold ants quickly climbed to the front, and a bolder ant climbed into the leaves.He stopped inside for a while before coming out, and he looked very scared.

我觉得这个实验还不能验证蚂蚁的记忆力,因为蚂蚁只要顺着我铺的路爬,肯定就能回到家。于是,我快步走到蚂蚁们前面,赶紧用小铁锹把刚才这条大路分了个支岔,并把另一条延伸到小树林。这两条路一条是通向蚂蚁窝,而另一条是通向小树林的。

I think this experiment can not verify the memory of ants, because as long as the ants climb along the road I paved, I can definitely return home.So, I walked quickly to the ants, and quickly divided the road just by Xiaotai, and extended another one to the small woods.One of these two roads leads to the ant nest, and the other is the forest.

我真没想到,这些蚂蚁居然没有一只爬错方向。我用放大镜一看,哇,那些小蚂蚁并不单靠气味回家,还用脑袋记着路呢!

I did not expect that these ants did not climb the wrong direction.I looked at the magnifying glass, wow, those little ants did not just go home by the smell, but also remember the road with my head!

真是一次有趣的实验,看来蚂蚁真的有超强的记忆力啊!

It is an interesting experiment. It seems that ants really have a strong memory!

10、喷射火焰与快乐_科学小实验作文300字

今天我和哥哥、小龙、刘泽一起准备作个“喷射火焰”的实验。

Today, my brother, Xiaolong, and Liu Ze are preparing to perform an experiment of "spraying flames".

我们找一个打火机,又找一个小铁管子,材料已准备好了,现在“万事俱备——只欠实验。”

We find a lighter and a small iron pipe. The materials are ready. Now "everything is ready -only in the experiment."

小龙拿着打火机,我拿着铁管子,将打火机对准管子的一头,将打火机调到最大的火力。哥哥和刘泽先在一旁观看,(不要离管子太近,不然会被火焰烧伤)。“预备,开点。”刘泽一声令下,“嗖”的一下,那火精灵从狭窄的管子里你推我挤的,争先恐后的向管外那片蓝天冲去,那熊熊烈火如子弹般从铁管一头冲向另一头,“哇啊哦!真壮观呀!”我们异口同声的说:“那火团,如一个小蘑菇,有些圆,也有些弯。那火精灵,向四面八方跑去,霎那间就消失得无影无踪。我们见了,欢呼雀跃!

Xiaolong took the lighter. I took the iron tube to aim the lighter to the tube and adjust the lighter to the maximum firepower.Brother and Liu Ze watched it first, (don't be too close to the pipe, otherwise it will be burned by flames)."Ready, open some." Liu Ze ordered, "嗖", the fire elves pushed me from the narrow pipe, and rushed to the blue sky outside the tube.From one end of the iron pipe to the other, "Wow! It's spectacular!" We said in unison: "That fire ball, like a small mushroom, a little round, and some curved.It disappeared without a trace. We met and cheered!

在我与伙伴们的心中,放出了快乐美丽的礼花。

In my hearts with my partners, happy and beautiful flowers were released.

11、我学会了区分生熟鸡蛋_四年级写事作文500字

星期天的早上,妈妈煮完鸡蛋,不小心把生鸡蛋和熟鸡蛋混在了一起。妈妈拿起一个个鸡蛋,左看看,右看看,就是找不到熟鸡蛋。看着妈妈忧愁的样子,于是我揽下了“区分生熟鸡蛋”这一个任务。

On Sunday morning, my mother finished the eggs and accidentally mixed raw eggs with cooked eggs.Mom picked up the eggs, took a look at the left, and looked at the right, but could not find the cooked eggs.Looking at my mother's sadness, I took the task of "distinguishing raw cooked eggs".

我想啊想,想到了一个办法,就是敲破鸡蛋。但我又想:如果把鸡蛋都敲破,那不是要吃好多天的鸡蛋,吃不了的还要浪费的。我觉得这种方法不可行。于是,我拿起鸡蛋又细细地看了起来。我看见鸡蛋的较尖的一端,我联想到了我的玩具――陀螺。我自言自语说:“何不妨把鸡蛋旋转起来呢?”于是,我把鸡蛋转了起来。我发现鸡蛋有的转得快,有的转得慢。我把转得快的放在一边,慢的放在另一边,最后一比较,转得慢的鸡蛋比转得快的鸡蛋多,所以我断定:转得快的是熟鸡蛋,转得慢的是生鸡蛋。后来,我又在手机上查到了旋转快慢不同的原因。原来是因为生鸡蛋里面是液体,所以旋转起来会重心不稳,东倒西歪。而熟鸡蛋是固体,所以旋转起来十分的平稳快速。看到解释,我豁然开朗,

I think, I think of a way to break the eggs.But I thought again: If the eggs are broken, it is not necessary to eat the eggs for many days, and it will be wasted if you can't eat it.I think this method is not feasible.So I picked up the egg and looked at it carefully.I saw the pointed end of the egg, and I thought of my toy -the gyro.I said to myself, "Why don't you rotate the eggs?" So, I turned the eggs.I found that some eggs turned fast and some turned slowly.I put the turn fast aside, slowly on the other side, and the last comparison, the slow -moving eggs are more eggs faster than the eggs that turn faster, so I conclude that the cooked eggs are turned fast.It's raw eggs.Later, I found the reasons for rotating fast and slow on my mobile phone.It turned out that because the raw eggs were liquid, it would be unstable when rotating, and it was crooked.And cooked eggs are solid, so rotating is very smooth and fast.Seeing the explanation, I was suddenly cheerful,

晚上,妈妈回来时,我把区分生熟鸡蛋的方法告诉了妈妈。妈妈赞扬我说:“你真棒!”我听了心里美滋滋的。

In the evening, when my mother came back, I told my mother about the method of distinguishing raw and cooked eggs.My mother praised me and said, "You are awesome!" I heard my heart.

12、鸡蛋的乐趣_实验作文600字

昨天上语文课时,老师说:每个人准备两个鸡蛋装在口袋里,要小心保护,不能碰碎。同学们都觉得挺新鲜的。

When I took a Chinese class yesterday, the teacher said: Everyone prepares two eggs in their pockets. Be careful to protect it and not be broken.The students all felt fresh.

今天早晨,我们班上可热闹了,大家三三两两地聚在一起交头接耳的,每个人脸上都露出神秘的笑容,似乎每个同学对老师的这项作业都充满了好奇,而我也毫不例外。

This morning, our class was lively. Everyone gathered together in three or two. Everyone's face showed a mysterious smile. It seems that every classmate is curious about the teacher’s homework, and I am no exception.Essence

自从早晨起床拿两个鸡蛋放入口袋的时候,手基本上就没离开过鸡蛋。即使和同学在玩,心里也想着口袋里的鸡蛋要“小心”。上课时也小心翼翼地,生怕自己稍不留神弯腰把鸡蛋压碎。下课了,留在班上的同学比平时多了不少,几个平时非常好动的同学也规规矩矩地坐在教室里。

Since getting up in the morning and putting two eggs in pockets, my hands have basically never left the eggs.Even if you are playing with your classmates, you think about the eggs in your pocket to be "careful."During the class, I was also careful, for fear that I would be bent down and crushed the eggs without paying attention to it.After class, there are a lot of classmates in the class than usual. Several students who are very active are also sitting in the classroom regularly.

后来同学们又在鸡蛋上面找乐趣了,他们在鸡蛋上面精心地画一些自己喜欢的卡通人物,并给它们取出各种有创意的名字。我也不甘落后,在第一个鸡蛋上面画个漂亮的女孩,名叫“麦子宝贝”;在另一个上面画一个男孩,取名“酷仔”。怎么样,够酷的吧!还有更好玩的呢!你听了,一定会笑破肚皮的。

Later, the students were looking for fun on the eggs. They carefully painted some cartoon characters they liked on the eggs and gave them all kinds of creative names.I am not willing to fall behind. I painted a beautiful girl on the first egg, named "Mai Zi Baby"; a boy was painted on the other, named "Cool Tsai".How about, cool enough!And more fun!When you listen, you will definitely laugh.

呵呵……我们班的“小胖子”给自己的鸡蛋取了两个特别的名字,一个叫“坚忍不拔”,另一个叫“弱不禁风”。原因是他把两个鸡蛋故意地一碰,第一个完好无损,而第二个一骨碌地滚到地上碎了。所以那两个有趣的名字油然而生。还有“数码宝贝”、“小丑王”……怎么样,我们的同学都很可爱吧!

Hehe ... The "little fat man" in our class gave his eggs for two special names, one called "perseverance", and the other was "weak".The reason was that he deliberately touched the two eggs, the first one was intact, and the second bone rolled to the ground to break.So those two interesting names spontaneously spontaneously.And "Digimon", "Clown King" ... How about, our classmates are very cute!

虽然这个游戏只持续了一天,但我却从中悟出了一些道理:如果决心做一件事,只要用心去做,就一定能做好。

Although this game lasted only one day, I realized some truths: If you are determined to do one thing, as long as you do it with your heart, you will be able to do it well.

五年级课本中的小实验:每个学生在一天内口袋里揣两个鸡蛋,比一比、赛一赛,看谁的鸡蛋保持得最好。

Small experiments in the fifth grade textbook: Each student holds two eggs in his pockets in a day, compared with one and one game, and see who's eggs are the best.
