Classmates, had you seen firm white paper? Do a magical little test together with me please!
同学们,你们见过坚强的白纸吗?请和我一起做一个神奇的小实验吧!
Experimental data mixes straightedge with preparation only paper of a piece of A4. Above all on the desktop that my general straightedge puts a piece of level, let rule 1/3 outside the desktop, say stealthily to rule: "Fasten confused, I give you warm on the lid warm quilt. " then I cover a white paper to it along the desktop. Finally, I raise fist of right hand enclasp, show to rule forcibly quickly outside 1/3 part is bungled go down, afraid all the time rule can fly to decline in the heart on the ground...
实验材料只用准备一把直尺和一张A4纸。首先我将直尺放到一张平整的桌面上,让尺子的三分之一在桌面外,并悄悄地对尺子说:“别慌,我给你盖上暖暖的被子。”接着我沿着桌面给它盖上一层白纸。最后,我举起右手握紧拳头,快速用力向尺子露在外面的三分之一部分砸下去,心里一直担心尺子会飞起来跌落到地上……
Well! Rule and white paper did not fly actually! Be me is strength not quite great? I tried again according to original measure again, can be rule actually apathetic, still firm quietly sleeps on the desktop.
咦!尺子和白纸竟然没有飞起来!难道是我力气不够大?我再一次按照原来的步骤又试了一次,可是尺子竟然无动于衷,依然稳稳地睡在桌面上。
Is this why? I 100 think of do not get its to solve, let mom examine a data on the net then. Because air is lacked between white paper and desktop,be so, play rule suddenly, make the air here fewer, cause air pressure to pin paper, pin rule then, make rule bounces not easily.
这是为什么呢?我百思不得其解,于是让妈妈在网上查了一下资料。原来是因为白纸与桌面之间缺乏空气,突然一弹尺子,使这里的空气更少,造成空气压力压住纸,进而压住尺子,使尺子不易弹起。
This scientific little test, I cut the fun that cut the ground to experience an experiment really not only, still mastered a few scientific knowledge. I should do more scientific little tests later, let scientific knowledge enrich my cerebra!
这次科学小实验,我不仅真真切切地体验了实验的乐趣,还掌握了一些科学知识。我以后要做更多的科学小实验,让科学知识充实我的大脑!
