We take a steady shower stream and clean drinking water for granted, but in many countries around the world, the lack of water or a clean water supply is responsible for higher sickness and death rates. Taking a closer look at the water...

Students complete activities where they observe the amount of freshwater in the world as a fraction of the actual amount of water using different mixtures. In this freshwater lesson plan, students brainstorm on how to preserve...

Rain, rain, go away—wait, there it is again! Elementary scientists learn how rain works its way through the stages of the water cycle with a series of classroom lessons and hands-on activities.

Water is vital for survival, but how does it help global cultures flourish? Elementary and middle schoolers learn about the different cultures around the world that celebrate water and incorporate it into their festivals or traditions.

How is it that water that falls as rain ends up coming out of the tap on our sinks? Learners trace water's journey and examine how along the way pollutants make their way into the water supply. They conduct experiments, use the Internet...

The basic elements of the water cycle and how water is recycled through our environment is focused on in this lesson. Your students construct classroom terrariums and learn to make and record observations relating to the water cycle....

How has human activity affected Earth's watersheds? An action-packed lesson plan, part of the K20 Center, examines water's ability to go with the flow regardless of what is in its path. Scholars build model watersheds, examine time-lapse...

Rally your administration and facilities manager to let your class examine the water flow rates in different areas of the school. After the audit, the class researches opportunites for conserving water and writes a report or develops a...

Students study water conservation. In this water conservation lesson, students investigate the scarcity of water and determine reasons for conserving water.  Students estimate how much water they use in one day and identify ways to...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

After a whole-class discussion of water reservoirs, ten liters of water are given to each lab group to represent Earth's total amount of water. They divide the water into smaller containers, each representing one of those reservoirs. The...

Here is a great way to get pupils to express a scientific concept in a fun way. After hearing the story of Walter the Water drop and learning facts about the water cycle, the class will write a creative expository piece describing what...
