A day afternoon, I and father mother preparation do a little test. Experimental name is ” of “ magic water, it is the small experiment of egg of float of a brine actually.
一天下午，我和爸爸妈妈准备做一个小实验。实验名是“有魔力的水”，其实就是一个盐水浮鸡蛋的小实验。
Ground of my too impatient to wait wants to see the look that the egg rises in the float in brine. Before the experiment, want to prepare a few data, I take two cautiously about the same big egg; Take two smooth and transparent glass, put on the table; Take a packet of salt and a chopstick, it is finally in glass mount the water of about 3/4.
我迫不及待地想要看到鸡蛋在盐水里浮起来的样子。实验前，要准备一些材料，我小心翼翼地拿起两个差不多大的鸡蛋；拿来两个光滑透亮的玻璃杯，放在桌子上；拿来一包盐和一根筷子，最后在玻璃杯里装上大约四分之三的水。
Begin to do a test! Below the guidance of father mother, my preexistence puts an egg in a cup among them. Well? How doesn't the egg have float to rise? Oh, it is to want to put salt in water so ability is OK ah. I put two spoon salt, but the egg resembled be asleep however like motionless, I ask mother: “ why don't egg or float rise? Full marks / ” mom affectionately replies: Because buoyancy is too small,“ is then, need puts salt of a few spoon more again. ” caught me to put 3 spoon salt again, with the chopstick sufficient agitate makes salt was dissolved. Not a little while, the egg shakes sway placed the ground to rise, my experiment succeeds eventually!
开始做实验了！在爸爸妈妈的指导下，我先在其中一个杯子里放入鸡蛋。咦？鸡蛋怎么没浮起来呢？哦，原来是要在水里放入盐才可以呀。我放了两勺盐，可鸡蛋却像睡着了似的一动不动，我问妈妈：“为什么鸡蛋还是浮不起来呢？满分/”妈妈亲切地回答：“那是因为浮力太小了，需要再多放几勺盐。”接着我又放入了三勺盐，用筷子充分搅拌使盐溶化了。不一会儿，鸡蛋就摇摇摆摆地升了上来，我的实验终于成功啦！
Ground of my feel puzzled asks father: Why does “ put saline egg in water can does float rise? ” father says: “ because identical solid is in different solution,this is, buoyancy is different, among them mystery differs with respect to what depend on clear water and brine, the flotage that the egg gets in brine is bigger than its oneself weight, rise with respect to meeting float so. ” I nod, say: I understand “ ! ”
我疑惑不解地问爸爸：“为什么在水里放入盐鸡蛋就能浮起来呢？”爸爸说：“这是因为相同的固体在不同的溶液中，浮力是不一样的，其中的奥秘就在于清水和盐水的不同，鸡蛋在盐水里受到的浮力比它自身重量大，所以就会浮起来。”我点了点头，说道：“我明白啦！”
This experiment let me know a few scientific principles. I feel we want to do an observant and conscientious person in the life, be good at observation, with respect to the results that can want to be less than of purpose.
这次的实验让我知道了一些科学原理。我觉得我们要做生活中的有心人，善于观察，就会有意想不到的收获。(文/唐博)
