实验准备:食用盐,自来水,陶瓷茶碗,煤气灶,筷子,漏勺。第一步:放盐方法:在陶瓷小碗里放入两小勺食用盐。我的发现:一粒粒白色的食盐像小小的雪雹子,紧紧挨在一起。第二步:加水方法:向碗中加入自来水,加到约七分满(太满容易溢出)。我的发现:盐粒都沉到了碗底,碗底中心的盐粒最少。 Experimental preparation: salt, tap water, ceramic bowls, gas stove, chopsticks, colander. The first step: salt method: Add two teaspoons of salt in ceramic small bowl. My discovery: a grain of white salt like small snow hailstones, close together. The second step: water method: add water to the bowl, add about seven full (too full to easily overflow). My discovery: Salt pellets sink to the bottom of the bowl, with the least amount of salt in the center of the bowl.
