小朋友们，你们知道下雨后地上的水去哪里了吗？其实它们在做一场神奇的旅行哦！让我们跟着小水滴，看看它们会发生什么。
太阳一晒，小水滴就变轻啦，慢慢飞到天上变成看不见的水蒸气。这个神奇的过程叫做蒸发。
水蒸气飞到高高的天空，遇到冷空气就聚集在一起，变成了白白的云朵。云朵里有很多很多小水滴呢！
云朵里的小水滴越来越多，挤不下的时候就会掉下来，变成雨或者雪回到地上。
这些水有的钻进泥土给小草喝，有的流进小河里，等太阳出来又会开始新的旅行。这就是水的循环，是不是很有趣呀？
The sun makes water droplets lighter and they slowly fly up to the sky, becoming invisible water vapor. This magical process is called evaporation.
Water vapor travels up to the sky and meets cold air, clustering together to form fluffy white clouds. The clouds contain many tiny water droplets!
When clouds get too full, water falls down as rain or snow! The tiny droplets become too heavy to stay in the sky, so they return to earth as precipitation.
Water goes to different places for new adventures! Some soaks into soil to nourish plants, some flows into rivers, and when the sun comes out, the cycle starts again. This is the water cycle - it never ends!
