大家知道么?我们身边处处都有科学。如果你不知道,我就举几个例子吧!
有一次,我在吹气球时,一不小心没有捏紧,气球中的气“溜”了出来。我心想:为什么气球不扎口,气球会变小呢?我百思不得其解。到了后来,我从书上查过资料才知道,松开手后气球变小,是因为气球的橡皮膜收缩,气球里的气从口里“溜”了出来。所以气球会变小。我又发现,气球吹起来跑气时,气球可不老实了,会到处乱飞。多次实验后,我发现了一个有趣的现象,气球飞起来的方向跟气球口所对的方向正好相反,也就是说,气球往上跑气,气球就往下掉,气球往左跑气,气球就往右窜,这可真有意思!
我一抬头,正好发现桌子上的玩具小车,一个想法就冒出来了:气球漏气时窜得那么快,看来“威力”不小,能不能带动小车呢?我就先把气球吹成梨子大,卡在小车上,等我一松手,奇迹出现了:伴随气球的出气声,小车竟然往后倒退了两三寸。我大声喊起来:“妈妈,妈妈,气球带着小车跑了!”我又照着刚才的方法演示了一遍,只不过气球吹的更大了点,小车也就多跑了一点。妈妈笑着说:“孩子,你的实验很成功,这是一种作用力与反作用力,是一种物理现象,到你上初中的时候你就会学到这方面的知识。运载火箭能够飞上天,靠的也是这种力量。”
这是真的吗?一个小小的气球,竟然给我带来了这么有趣的知识。我要细心观察,了解到更多的科学知识。
回到家,随手打开灯。“咦?怎么不亮?”停电了吧,我嘟嚷着。稍作停留后,迎着大雪到附近商店里买了一支蜡烛。透过玻璃,依稀可见一片片晶莹剔透的雪花落在头发上,增添了一分唯美之意。
天色已晚,周围的路灯散发出柔和的光,我一路小跑,在学校踩出一个个脚印。家里漆黑一片,伸手不见五指。我摸索着,拿着打火机将蜡烛点燃,小心翼翼的放在桌上。百般无聊的`望着蜡烛,心中不由得冒出一个想法:不知道隔纸加热会出现怎样的结果呢?
说做就做,我将防水纸折成盒状,放在架子上加入少许清水,再在架下放上一支正在燃烧的蜡烛。我趴在桌子上,静静的看着。
时间一分一秒的流逝,水渐渐变热,我诧异的挑了挑眉。不一会,水上冒出了几个小水泡,水热了,纸却没有燃烧。我对这个实验结果充满了不解。打开电脑百度后,得知:可燃物的燃烧必须与氧气接触,温度要达到可燃物的燃烧点。这两个条件必须同时具备,可燃物方能燃烧。隔纸加热,水能传热,使纸的温度没有达到纸的着火点,所以纸不能燃烧。
其实身边处处都有科学,只要你用心去发现,用心去做,就会获得你意想不到的收获。
