Year 4 have been learning about the water cycle this week. They have been explaining the main events of the water cycle, where the processes of evaporation and condensation occur and that it keeps going in a closed cycle.
Using a ziplock bag & a little bit of coloured water, we created a demonstration that shows how Earth’s natural forces work. By hanging our Water Cycle Bag in the window, we started to see the water evaporate and condense into tiny droplets (this is how clouds are formed). When the droplets become bigger, they ran down the side of the bag (this is precipitation, like rain), and the water then pooled again at the bottom of the bag (this is collection, like lakes and oceans). And then just as it does on Earth, the water cycle began again.
