Scientific Absolutes

Second-year student, EK, has enjoyed many lessons in science over the years. One day, during our daily class discussion on weather, he asked me, "Why does it rain?". I explained to him that the clouds fill up with water droplets. The droplets get too heavy and fall from the clouds. I reminded him of a science experiment we did last year. We used an eyedropper to add drops of water to a cotton ball (cloud). The children watched it fill up until the cloud started to "rain". EK thought for a moment and said, "So I guess the rain always falls, like the Earth always spins". Absolutely.
