今天,我在家里看了一本书,书上有个小实验,我挺感兴趣的,就决定去试一试。我准备了一个苹果,两个碗,其中一个碗是装了盐水的。我先用刀把苹果皮削下来,把它切成一小块一小块的。一半放在空碗里,另一半放进装盐水的碗里。大约过了两分钟,我去看两个碗里的苹果。空碗里的苹果已经开始变得有点浅褐色了,而盐水里的苹果却还保持着原来的颜色。如果让它们放置的时间再长一点又会怎样呢? Today, I read a book at home. There was a small experiment in the book. I was very interested and decided to give it a try. I prepared an apple, two bowls, one of which was filled with salt water. I first cut the apple skin with a knife and cut it into small pieces and small pieces. Put half empty bowl, the other half into salt water bowl. After about two minutes, I went to see the apples in two bowls. The apples in the empty bowl are starting to get a little beige, while the apples in the saltwater keep their original color. What if they were put in for a little longer?
