Today, the teacher decorated a special operation, the egg float in doing a “ to let water rises the small experiment of ” , does the meeting float with the true egg in water rise? I cherish curious mood, according to the teacher's requirement, begin to start work seriously do a test.
今天，老师布置了一项特别的作业，做一个“让水中的鸡蛋浮起来”的小实验，水中的鸡蛋真的会浮起来吗？我怀着好奇的心情，按照老师的要求，开始认真动手做实验。
I prepared an unripe egg, a glass, a cup of clear water, salt and a chopstick.
我准备了一个生鸡蛋，一个玻璃杯，一杯清水，盐和一根筷子。
The experiment began, do not pour clear water into glass too completely above all, 2/3 OK, then I go to the egg gently put in the cup, “ attacks of ” , the egg sinks at a draught in cup bottom, I still heard the voice of bottom of egg collision cup, I observe carefully, not bad the egg did not break, at this moment the darling that the egg is like sleep deeply, lie in cup bottom motionless. Salt is put in past water namely next, I put first time salt of one small spoon, with chopstick agitate, the egg changes without what in the cup; The 2nd times I put two spoon salt, use full marks again / chopstick agitate, right now water becomes cloudy, the egg also appears conciously the tiptoe since ” of “ stand on tiptoe, seem to also sleep again bad; I added dot salt again, use chopstick agitate again, this the egg showed cerebella bag on surface, I stopped agitate, take the chopstick, the egg did not sink in benthic, however suspension is in water, want to drink a cup gently only, the egg resembles malty same, float shakes leisurely of shake from side to side in water. I cry gladly: “ egg float rose, my experiment succeeded ” .
实验开始了，首先把清水倒入玻璃杯中不要倒得太满，倒三分之二就可以了，接着我把鸡蛋轻轻往杯里放，“扑”的一声，鸡蛋一下子便沉在杯底，我还听到了鸡蛋碰撞杯底的声音，我仔细观察，还好鸡蛋没有碎，这时的鸡蛋好像沉睡的宝宝，躺在杯底一动不动。然后就是往水里放盐，第一次我放了一小勺盐，用筷子搅拌，鸡蛋在杯里没有什么变化；第二次我放了两勺盐，再次用满分/筷子搅拌，此时的水变浑浊了，鸡蛋也似乎有意识地“踮”起脚尖，好像再也睡不好了；我又加了点盐，再次用筷子搅拌，这次鸡蛋在水面上露出了小脑袋，我停止了搅拌，把筷子拿出来，鸡蛋没有沉在水底，而是悬浮在水中，只要轻轻动一下杯子，鸡蛋就像喝醉了一样，浮在水中晃晃悠悠。我高兴地叫起来：“鸡蛋浮起来了，我的实验成功了”。
Do I ask mom the egg is so heavy why to meet does float rise? Mom tells me to add salt in water, it is to increase the proportion of water, when salt increases certain amount, the proportion of water can be more than the proportion of the egg, egg nature rose with respect to float. Oh, such before, my suddenly be enlightened.
我问妈妈鸡蛋那么重为什么会浮起来呢？妈妈告诉我在水中加盐，就是为了增加水的比重，当盐加到一定量时，水的比重就会大于鸡蛋的比重，鸡蛋自然就浮起来了。哦，原来如此，我恍然大悟。
Today this experiment, let me harvest the joy that does a test not only, still understood a scientific reason.
今天这个实验，不仅让我收获了做实验的快乐，还明白了一个科学道理。(文/成景丽)
