E has told me that her most favorite part of school is doing science. Today we learned more about rain and hail. We are basically learning about the water cycle.
We did a simple experiment where we filled a glass with water and ice and watched as the outside of the glass got wet (why we need coasters, i guess). We learned that the water vapor in the air turned back into water or 'condensed' when it touched the cold glass, because when water vapor gets cold, it turns back into water.
Then we read a good book that explained it very clearly in grade one language. It's called Down Comes the Rain by Franklyn Branley. This series of books is very well written and I highly recommend it.
Below is her drawing and her 'narration' to me of how the water cycle works. Water vapour comes from rivers and oceans and seas. It turns into water vapour by the sun. Water vapour is always everywhere. Even in the house. It’s on trees, horses, cows and us too.
The water vapour turns into a cloud because if you go further away from the earth it gets colder and colder. The water vapour turns back into water to become a cloud.
The little droplets stick together, and the clouds become bigger and bigger with more water vapour and then the little droplets fall down as rain.
