The water cycle, called a hydrological cycle (hydro, meaning water), is one of the biogeochemical cycles. Life on the earth is highly dependent on regulating the water cycle. Water continuously moves from the land (soil, water bodies, glaciers, mountains, plants) to the atmosphere and back to the ground.
Did you know the water you’re drinking may have once been part of a glacier in the Antarctic? The heat from the sun converts surface water into water vapors that move into the atmosphere to form clouds. When the clouds become heavy, they start pouring these water vapors back on the earth in the form of precipitation. Plants also play an essential role in either intercepting the falling water or giving back the water from solid to the atmosphere through transpiration.
The paragraph above summarizes the water cycle, but it gets more detailed and challenging at the high school level. Introducing new aspects of the hydrological cycle often makes students interested in the subject. Likewise, some educators struggle to make it a comprehensive and approachable topic.
Labster identifies these challenges in this article and proposes five practical solutions to overcome this issue. Keep reading to find out the ways you could implement in your classroom to make the water cycle a more approachable topic for students.
College/university students are already familiar with the basic concept of the water cycle. However, they were only taught a summary of the subject in school. They learn about the intricate details of the water cycle in school. This change confuses some students who thought it would be a simple subject. The top three reasons making the water cycle a tricky topic for educators and students are as follows:
Water in any form and from any place is destined to go back and forth into the ecosystem regulating the water cycle. It seems like there is no beginning or end to the water cycle. Some students might find it challenging to keep up with the water cycle's small details. Similarly, many educators get lost in the heap of information and fail to share the important stuff.
It plays an essential role in the ecosystem's cycling sediments, solar energy, and chemical elements. The geological evolution over time has somewhat influenced the water cycle. Scientists are still trying to figure out delicate linkages impacting the natural circulating water process on earth. Human activities have sufficiently tampered with regulating some operations in the water cycle, like evaporation, precipitation, etc. Many students consider it a complex topic when they learn intricate details like the water cycle's relationship with life and the earth's geology.
There are eight essential processes primarily responsible for governing the water cycle. Some students could confuse evaporation, transpiration, infiltration, and interception. It challenges educators to develop effective strategies to help students easily comprehend these terms. Some educators might underestimate these terms' significance before teaching the water cycle details.
The water cycle is a fascinating topic if approached in a systemized manner. Here are a few suggestions you could implement in the classroom to increase student engagement and participation rate.
The water in the water cycle revolves from one reservoir to another through a series of processes. Start your lesson by defining/introducing these processes to make students feel relatable to the phenomenon. Following are some essential terms that students should be familiar with before diving into the water cycle.
Students show more interest and understanding of the revised water cycle and become familiar with these terms.

The examples of water cycles could easily be observed in our surroundings. It would make students realize the significance of the water cycle. For instance, condensation is observed around us in the form of morning dew or fogged mirrors. The liquid drops on a soda can appear when water vapors in the surrounding air hit the surface of the can, changing water vapor into water. The boiling process is an ideal example of evaporation as the volume of water decreases due to molecules evaporating in the form of gas from the surface.
Motivate students to think and share examples where they could observe water moving from one form/place to another. It would make the water cycle topic fun and exciting for students at all levels.
The working water cycle model is an interactive learning activity that would help clarify concepts and understand the intricate details. Teachers should encourage students to do some research and independently make a unique model. This activity could also be done in groups, developing team spirit and harmony among students.
The college/university-level model should include in-depth concepts like how pollution or global warming impacts the water cycle. This would help students grasp the advanced and latest aspects making learning a valuable experience. Such activities help educators explain scientific concepts easily while keeping students engaged and hooked.
Spark students’ interest in learning more about the water cycle through a tried and tested method - sharing fun facts in the classroom. Look for the most awe-inspiring facts that would motivate students to uncover further details about the intertwined hydrological cycle. Some of the things that you could share with your class are as follows:
A virtual laboratory simulation is a great way to teach the water cycle. At Labster, we're dedicated to delivering fully interactive advanced laboratory simulations that utilize gamification elements like storytelling and scoring systems inside an immersive and engaging 3D universe.
Check out Labster's Principles of the Water Cycle Virtual Lab. In this simulation, you will learn how water moves around the Earth in a continuous process.
