Attend class the bell rang, the teacher took a lot of material to walk into a classroom. What can today's composition class write? I was full of curiosity, was full of again expect.
上课铃响了，老师带了很多材料走进了教室。今天的作文课会写什么呢？我充满了好奇，又充满了期待。
The teacher says: "We do a test first today, write a composition again. " wow! Immediately boiling rises in the classroom, right now my heart also exploded like the balloon same, become very happy, want to know I was interested in these most.
老师说：“我们今天先做一个实验，再写作文。”哇！教室里顿时沸腾起来，此时我的内心也像气球爆炸了一样，乐开了花，要知道我对这些最感兴趣了。
The name of this experiment cries: Egg can " swim " on surface? The egg is heavier than water, how can you float rise? A lot of little unsolved problem appear in my heart.
这次实验的名称叫：鸡蛋能“游”上水面吗？鸡蛋比水重，怎么会漂浮起来呢？我心里冒出许多小问号。
Experimental data is very simple, it is OK to need club of young timber of egg, salt, small plastic cup, measuring glass and an agitate only.
实验材料非常简单，只需要蛋、盐、小塑料杯、量杯和一根搅拌小木棒就可以了。
The experiment began, teacher preexistence entered 400 milliliter water in measuring glass, put the egg then, water level line became 450 milliliter, where is egg? Everybody pop eye, had a body continuously, want to look after all? Hey! The egg sinks benthic, move also do not move, seemed to be asleep.
实验开始了，老师先在在量杯中倒入了400毫升水，接着把鸡蛋放入，水位线变成了450毫升，鸡蛋呢？大家瞪大了眼睛，直起了身子，想看个究竟？嗨！鸡蛋沉入水底，动也不动，好像睡着了。
Then, we continue to add salt, with wooden marvellous agitate, can be agitate very long, the egg also rises without float, just a little upgrade is played, of original issue what putting at salt at all is too little. The teacher added several spoon salt again, still can be no good, the egg is only float rose a few, look or cannot wake up the egg.
接着，我们继续加盐，用木棒搅拌，可是搅拌了很久，鸡蛋也没有浮起来，只是稍微往上弹了弹，原来问题的根本在于盐放的太少。老师又加了好几勺盐，可还是不行，鸡蛋只是又浮起来了一些，看来还是不能把鸡蛋唤醒。
The teacher is flat the bag that takes outfit salt pours salt directly, after adding half bags of salt again, egg eventually float rise, but had not risen to surface, seem to had not waked up, suspension is in the cup.
老师干脆拿起装盐的袋子直接倒盐，又加了半袋盐后，鸡蛋终于浮了起来，但还没浮出水面，好像还没睡醒，悬浮在杯中。
Everybody is eristic in succession, feel this experiment is like too won't successful.
大家议论纷纷，感觉这个实验好像不会太成功。
The teacher takes wooden club, begin to churn slowly rise. At the beginning, water becomes cloudy not clear, resemble a dense fog, see not clear gain, passed long after significant however agitate, opened its veil eventually, achievement thes whole thing comes to light, the egg is this eventually in water float rise, showed bag of a cerebella, this experiment also is a success, the big stone in our heart also calculates fall, classmates cheer caper rises, good a lively setting.
老师拿起木棒，开始慢慢地搅动起来。一开始，水变得浑浊不清，像一阵迷雾，看不清成果，经过了长久却有意义的搅拌后，终于揭开了它的面纱，成果水落石出，鸡蛋这次终于在水中浮了起来，露出了一个小脑袋，这次实验也算是成功了，我们心中的大石头也算落下了，同学们欢呼雀跃起来，好一番热闹的场景。
Finally, the teacher tells us, because saline flotage is bigger than water, so the egg can be in water " game " . Such experiment is really interesting grow knowledge again!
最后，老师告诉我们，因为盐的浮力比水大，所以鸡蛋可以在水中“游戏”。这样的实验真是又有趣又长知识啊！(文/周奕江)
