我在回家的路上高兴地手舞足蹈,我的实验会不会成功?鸡蛋煮熟后是什么样子?

回到家,我立马从冰箱里拿出一个鸡蛋,准备好醋、毛笔、小碗,实验就要开始了。我倒些醋在碗里,左手轻轻地捏着鸡蛋,右手拿起毛笔在碗里沾了些白醋,一字一顿在鸡蛋上写了一个“学”字,写好后我的右手迅速和左手合拢在一起,做出一个棒的姿势,也许因为太投入了,都忘记毛笔还在地上安静的躺着。

然后,我双眼盯着手上的\'鸡蛋,生怕它掉下来。谁知?我的脚不听使唤了,一个踉跄,鸡蛋也不听话了,从我的“牢笼”中逃了出去,鸡蛋好像很开心似的,在空中翻着跟头,好像在说:“终于能逃出来了!”可结果是——鸡蛋破了。

我看着这碎了的鸡蛋,默默的对自己说:“失败了,我还是放弃吧!”正当我要放弃的时候,我的心中想起了一个声音,那是妈妈的声音:“你要记住,越是紧张,越不能乱,要冷静地去面对它。困难像弹簧,你强它弱,你弱它强。”

我平静心态对自己说:“一次失败算什么,这次我一定会成功的。

第一次实验以失败告终,紧接着第二次实验即将开始。我和之前一样,用白醋在鸡蛋上写字,双方捧着鸡蛋,颤颤悠悠的向厨房走去,把鸡蛋轻轻放入水中。脑袋不断在提醒我:不能摔跤!不能摔跤!要小心!

终于,鸡蛋安全抵达了风干区域。风干后,我捧着鸡蛋,一会儿水就沸腾起来,鸡蛋也跟着这沸腾的水跳起“爵士舞”。 几分钟后,鸡蛋熟了,我兴奋地直接用手去拿,“呀!烫!烫!”我把手放在衣服上擦来擦去。我把蛋壳剥掉,竟呈现了我之前写的字。

我不明白这是为什么?所以到网上查了一番:白醋里含有醋酸,写在鸡蛋上之后通过鸡蛋壳和内膜进入鸡蛋,然后与鸡蛋清(蛋白质)产生了化学反应,产生了新物质,等鸡蛋煮熟之后蛋清变成白色的,自然就看见你写的字了。

这次实验让我明白了:做什么事情都需要经过自身的实践才能悟出其中的道理,科学知识真是无处不在啊!

Today was Sunday. My parents were free, too. I got up at 7\'oclock, because my families planed to go to the zoo. After the breakfast, I took the camera and went to the station together with my parents. It was already 9\'oclock when we arrived at the zoo. There were so many monkeys, tigers, lions, wolves and other animals in the zoo. We took many photos in the zoo with the animals. I will show these photos in my class after they were printed. The time passed so fast, we left the zoo at 1\'oclock PM. I was so happy today. Now I feel very tired and I will go to bed early tonight.
