漂浮的鸡蛋实验作文三年级

Hear the clear water that added salt can let an egg float on water. I want to do an experimental test and verify, satisfy my curiosity.

听说加了食盐的清水可以让鸡蛋漂浮在水上。我想做个实验验证一下,满足我的好奇心。

The material that makes this magical experiment need to prepare has: An an a packet of two the water cup like two scale, eggs, salt, a few clear water, chopstick, ladle.

做这神奇的实验需要准备的材料有:两个刻度一样的水杯、两个鸡蛋、一包食盐、一些清水、一根筷子、一把勺子。

Interesting experiment began. The first pace, I wait for the clear water of the quantity toward a cup and 2 cups infuse. The 2nd pace the salt that I put 5 spoon toward 2 cups, use chopstick agitate even. At that time, the brine that I discover 2 cups has done not have a chaliced clear water clear in that way, because dissolve entered the cause of salt, color slants white, if taste,perhaps meet of Xian Xian.

有趣的实验开始了。第一步,我往1号杯和2号杯注入等量的清水。第二步我往2号杯放入五勺的食盐,并用筷子搅拌均匀。这时候,我发现2号杯的盐水已经没有1号杯中的清水那样清澈,因为溶入了食盐的缘故,颜色偏白,如果尝一尝也许会咸咸的。

The 3rd pace, also be the last pace of result of test of test and verify, need is in 1 the egg is put in 2 date, cups. I put an egg into a cup first, see the egg sinks downward gradually only, sink after benthic no longer rock. My heart thinks, toward the egg is put in 2 cups, can also you sink like a chaliced egg benthic? In still resembling fokelore in that way is float in water? Our wait and see what happens!

第三步,也是验证实验效果的最后一步,需要在1号、2号杯中放入鸡蛋。我先把一个鸡蛋放入1号杯中,只见鸡蛋渐渐往下沉,沉入水底后不再晃动。我心想,往2号杯中放入鸡蛋,会不会也像1号杯中的鸡蛋沉入水底?还是像传说中的那样浮在水中呢?我们拭目以待吧!

Ground of my too impatient to wait puts the egg into 2 cups, magical thing happened, the float with 2 chaliced true eggs was in in water! I look at the salt that did not give out aside, brainwave easily, dug a few spoon to be put into water slowly again, use chopstick agitate, the niche that I discover to the egg is worn in the float in water is gone to again rose a few.

我迫不及待地把鸡蛋放入2号杯中,神奇的事情发生了,2号杯中的鸡蛋真的浮在了水中!我看着一旁没用完的食盐,灵机一动,又挖了几勺慢慢放入水中,并用筷子搅拌,我发现鸡蛋在水中浮着的位置又往上升了一些。

My agitato runs to see my place and discover tell mother, mom laughs slightly, say: "Because briny density is bigger than clear water, so the egg sufferred the influence of briny flotage to rise with respect to float. " I immediately suddenly be enlightened, scientific little test accumulate contain scientific principle, be too interesting really!

我兴奋地跑去把我的所见和发现告诉妈妈,妈妈微微一笑,说:“因为盐水的密度比清水大,所以鸡蛋受盐水浮力的影响就浮起来了。”我顿时恍然大悟,科学小实验蕴含科学道理,真是太有趣了!

Classmates, do you like this experiment?
