浮力真有趣

1、“浮力”真有趣-实验作文800字

“工作出聪慧，实践的重要性”。这是我今日做明德小学试验“鸡蛋浮起来了”后的体会。听了这一名称，你一定迷惑不解：鸡蛋怎么可能浮起来呢？假如你不敢相信，那就要我陪你一探究竟吧。

"The importance of work is intelligent, practice."This is the experience of my Mingde Elementary School test today.After listening to this name, you must be confused: How can eggs float?If you can't believe it, then I will accompany you to find out.

放学后回到家，我迫不及待地准备好试验原材料，有一袋食盐、一只生鸡蛋、一个灌满温开水的玻璃茶杯和一只木筷。万事俱备，只欠东风。

When I came home after school, I couldn't wait to prepare the test raw materials. There were a bag of salt, a raw egg, a glass tea cup filled with warm water and a wooden chopstick.All is ready except for the opportunity.

我提心吊胆地拿出鸡蛋，缓缓的放进水里。鸡蛋像一位跳水运动员，“扑腾”一声跳入水中，慢慢地沉到杯内，像一个小孩儿睡得正香起來。

I took out the eggs and slowly put it in the water.The egg was like a diving athlete, and he jumped into the water with a "flutter", slowly sinking into the cup, asleep like a child.

最先，我将一勺盐倒进杯里，随后渐渐地搅拌，鸡蛋跟随木筷的搅拌转动着。终止搅拌后，鸡蛋像一个醉鬼一样，摇摇晃晃往下掉，不一会儿又沉在杯内“睡长觉”，一动不动。我很迷惑不解：这只鸡蛋为什么没有浮起来呢？

First, I poured a spoonful of salt into the cup, and then stirred gradually.After terminating the stirring, the eggs were shaking down like a drunk, and after a while, he sank in the cup to "sleep long", motionless.I am confused: Why didn't this egg floating?

然后，我又倒了小量的盐，逐渐搅拌，可是鸡蛋如同生了根一样，对于我爱理不理。不甘落后的我再次往杯子里加上食盐，直倒添加第八勺时，惊喜总算发生了！小鸡蛋宛如一个睡梦初醒的小孩，糊里糊涂地伸了懒腰，恋恋不舍地离开自己舒服的单人床，精神焕发地站了起來，身体变轻了了，渐渐地升高，呈半浮情况了。

Then, I poured a small amount of salt again and gradually stirred, but the eggs were as raised as I had a root, ignoring me.I was unwilling to add salt to the cup again, and when I added the eighth spoon to add it, the surprise finally happened!Little eggs are like a child who wakes up in a sleeping dream, stretching his waist in a confused manner, and reluctantly left his comfortable single bed.The situation.

我的心里乐开花，鸡蛋总算要浮起来了！我信心倍增，再往杯子里添加食盐。这时候，杯子里的水早已一不小心搅拌得十分混浊了，成千上万细微的盐粒在水中漂动。椭圆形的鸡蛋被密麻麻的气泡包囊住，如同穿上了一件天然珍珠晚礼服，十分好看，它伴随着流水不断地旋转着身体。当我们加到第十四勺的情况下，盼望已久的時刻总算到，我的小鸡蛋如同一位花样游泳选手，在演出精彩纷呈的“水中芭蕾”，姿势是那麼风姿绰约。你瞧，她完成了赛事，雅致地浮起了河面，迎来着粉丝们掌声雷动呢！

My heart blooms, and the eggs are finally floating!I have doubled confidence and add salt to the cup.At this time, the water in the cup had been accidentally stirred very turbid, and thousands of fine salt drifted in the water.The oval eggs were covered by dense bubbles, as if wearing a natural pearl evening dress, which was very beautiful. It continued to rotate the body with flowing water.When we added to the fourteenth spoon, the long -awaited moment finally arrived, my little eggs were like a fantastic swimmer, and the performance was so graceful in the wonderful "ballet".You see, she completed the event, and the river surfaced elegantly, ushered in applause of fans!

我奇怪地问妈妈：“为何在水里放盐就可以让鸡蛋浮起来呢？”妈妈笑眯眯地对我说：“鸡蛋在浓盐水里能露出水面是由于盐水的密度比鸡蛋的密度大，与此同时，浮力也扩大，当水的浮力超过鸡蛋的净重时，鸡蛋便会飘起来了。”我猛然豁然开朗。

At the same time, the buoyancy also expands. When the buoyancy of the water exceeds the net weight of the eggs, the eggs will float. "I suddenly suddenly opened up.

多么的有意思的科学试验啊！只需大家擅于发觉，勇于开拓，一定能获得大量的获得。学生们，让我们一起勤奋，解开大量的科学研究秘密吧！

How interesting scientific trials As long as everyone is good at finding, the courage to develop, they will definitely get a lot of gains.Students, let's work hard together and solve a lot of scientific research secrets!
