Today, the teacher brought an egg, an an a beaker, spoon, chopstick.

今天,老师带来了一个鸡蛋,一个烧杯、一把汤勺、一根筷子。

This class, what should the teacher do? I am interrogative.

这节课,老师要做什么?我疑惑着。

See a teacher only first beaker replete water, in putting the egg into water again, the egg is just as diver to go to the end of the cup euqally, next, motionless, slept to become aware greatly.

只见老师先把烧杯装满了水,再把鸡蛋放进水中,鸡蛋犹如潜水员一样潜到杯底,然后,就一动不动,睡大觉了。

Who can make “ heavy rise to surface in the egg of benthic? Mr. ” says. Mr. “ , I will try. ” Lin Zhengbo answered, one spoon salt was spilled in past water. Right now, a little salt waves like flying heavy snow of all over the sky to cup bottom. Agitate of his reoccupy chopstick, like the ” of “ young join a regular shift or class that the egg resembles is a chopstick, follow at the back of the chopstick to turn ceaseless. But, after the chopstick stopped, the egg sank again benthic. At that time, we are stretchy neck, open big the eye is staring at an egg. A classmate says: “ rich so effort, why is the egg returned not does float rise? ” at this moment, the teacher started to talk: “ because, effort is insufficient still, egg ability float does not rise. ”

“谁能让沉在水底的鸡蛋浮出水面?”老师说。“老师,我来试试。”林正博应了一声,就往水里撒了一勺盐。此时,盐花就像漫天飞大雪一样飘向杯底。他再用筷子搅拌,鸡蛋就像是筷子的“小跟班”似的,跟在筷子后面转个不停。但是,筷子停了下来之后,鸡蛋又沉到了水底了。这时候,我们都伸长了脖子、睁大了眼睛盯着鸡蛋。有一个同学说:“正博都这么努力了,为什么鸡蛋还不浮起来?”这时,老师开口了:“因为,努力还不够,鸡蛋才浮不起来。”

rich understands at a draught, salt is spilled in past water again, continue agitate. Full marks / at this moment, the egg stood to rise slowly. Fellow students are very happy, the eye is staring at an egg closely. Continue to spill salt, continue agitate, egg eventually float rises, float in surface.

正博一下子就明白过来,再往水里撒盐,继续搅拌。满分/这时,鸡蛋慢慢立了起来了。同学们很开心,眼睛紧紧盯着鸡蛋。继续撒盐,继续搅拌,鸡蛋终于浮起来,漂在水面。

At that time egg, left look, right look, seem to saying: “ ! The world outside is really beautiful, the air outside is really fresh, I also do not go again benthic, want to admire a scenery in this surface only. ”

这时候的鸡蛋,左看看,右瞧瞧,好像在说:“哇!外面的世界真美丽,外面的空气真新鲜,我再也不去水底,只想在这水面欣赏风景。”

Classmates see egg on the surface rise, skip with joy 3 feet.

同学们见鸡蛋浮了起来,高兴得一蹦三尺。

I press the egg into water with finger, but, always feel to a powerful force is carrying an egg on the head.

我用手指把鸡蛋摁入水中,可是,总觉得有一股强大的力量顶着鸡蛋。

Why can the egg come on float? Why a force still is carrying an egg on the head? Listened to a teacher explain, I just understood: Original, after salt was added in water, the density of water greatened, the flotage that the egg gets also greatened, rose to surface.

为什么鸡蛋会浮上来?为什么还有一股力量顶着鸡蛋?听了老师的讲解,我才明白了:原来,在水中加了食盐后,水的密度变大了,鸡蛋受到的浮力也变大了,就浮出了水面。

Pass today's test, I realize gave a reason: In the process of study, dug, may have many stumbling block, at this moment, should continue hard, go thinking, go trying, go exploring, just have the possibility with happy success of conquer obstacle, results.

通过今天的实验,我悟出了一个道理:在学习、探究的过程中,可能会有不少拦路虎,这时,应该继续努力,去思考,去尝试,去探索,才有战胜拦路虎、收获成功喜悦的可能。(文/刘焯睿)
