Science -Learning About the Water Cycle in an Experiment

Science is my favorite subject to teach. It can be so much fun for me and my students! Students are able to perform hands-on experiments to learn about many scientific topics. The water cycle is one of these topics. In this water cycle experiment, we started with evaporation. Water was added to two clear cups, and a marker was used to mark the water line on both cups. One of the cups had a clear plastic wrap placed on top, which was secured with a rubber band. Then, cups were placed on the window seal for two days. Next, we started to look at what had occurred.


With this experiment, students were able to learn that the sun, or energy, caused a change in the water’s state of matter. Energy turned the liquid into a gas. Then, the water vapor or gas hit the plastic wrap, on one of the cups. This caused the gas to turn back into a liquid, which showed condensation. Condensation on the plastic wrap was our example of a cloud. Finally, the cloud got too heavy, which caused the drops fall back into the cup. This stage in the water cycle is precipitation. My students were also interested in seeing that the cup without the covering had less water, due to evaporation, after it had been placed in the sun for two days.


The experiment was a success! Plus, the students learned new information and had fun while doing it. In my classroom, hands-on activities are always the easiest way way to teach a new concept.
