Water Cycle in a Bag

Subjects: Biology
Topics: Water Cycle, Water State

Create your own water cycle without leaving the classroom!

The water cycle is a pretty big process which happens on, above and below the earth and this might be quite a task to observe naturally. However in this project, the students will be recreating it in a plastic zip bag by adding water and some food colouring into the bag and taping it to a sunny window. Then, all they have to do is wait and observe how the sun heats up the water and creates condensation. By tapping on the bag students can create “rain’’ and the cycle can start all over again.
