We have been learning all about the water cycle. To help us see this in our classroom we made our own small version of the water cycle in a sandwich bag. Firstly we drew the diagram on the bag and then added a little bit of water. We sealed our bags shut and stuck them to the window.
The heat created by the sun shining in the window will cause some of the water to evaporate and rise to the top of the bag where it will create condensation and water droplets will drop down the bag representing the rain outside.
