How Do You Design Water Cycle Experiments?
Learn how the water cycle works with experiments using simple household items. Depending on the age group, water cycle experiments can be easy or complex. The basic idea is to show how water condenses, evaporates and forms precipitation in ways that mimic the earth’s water cycle. Make a simple experiment with a clear glass bowl, plastic wrap, a few small stones, a smaller container such as a paper drinking cup or yogurt cup and some string or rubber band. Continue the simple experiment by placing the small container in the middle of the bowl. Put a small amount of water in the bottom of the bowl. Cover with plastic wrap, secure with the rubber band and put the small stones on top. Place the bowl in a sunny spot so there is heat to make the evaporation begin. Observe how long it takes for condensation to form on the plastic wrap and then drop back into the bowl. Try a more complex system with three large plastic pop bottles. Cut off the top of one and cut off the bottom of another. Put
