Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

Students compare bottled water qualities to water found naturally in a pond habitat. They research their state's laws/regulations in regard to bottled water and study the advertising, cost, and quality of brands of bottled water. They...

Students examine specific skills in assessing water quality from a holistic approach. They assess the health of a local watershed and identify problems in the local watershed and suggest remediation.

Here is a comprehensive method for assessing chemistry learners' knowledge; have them approach two laboratory problems, plan their methods of solving each, and then actually carry out the experiments to find the answers. Both the...

The goal of this collection of lessons is to make middle schoolers more aware of the ways in which they are dependent upon water to maintain their standard of living. Learners compare water use in Lesotho to water use in the United...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

Don't be so dense! Using food coloring, pupils conduct two experiments with the difference in densities of hot and cold water. In the first experiment, learners add dyed hot and cold water into room temperature water and observe how the...

Anyone that lives around snow knows that adding salts to water increases its melting point. Are there solutes that affect the boiling point as well? A scientific experiment has learners add different solutes to water and then...

Help young scientists get to the bottom of the water cycle with this comprehensive earth science lesson. After first viewing and discussing presentations about the states of water and the water cycle, the class performs a...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

Curious physical scientists follow a lesson on the properties of water with this lesson on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an enriching...

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Here is a great lesson designed for very young scientists. In it, they act out the famous Aesops fable, "The Crow and the Pitcher." In doing this, they get to experience water displacement first-hand. Some terrific extension activities...

Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

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...

Junior high schoolers learn how to read a water meter, track their family water usage, and discuss the amount in class with other pupils. They will interpret real-world data and graph it. It is ideal for increasing awareness and...

It's not long, but it's thorough! This PowerPoint takes 4th - 8th grade earth scientists deeper into the oceans. They learn about tide and current activity and the forces that drive them. They also discover how wind and the rotation of...

While the content of this lesson is more specific to the first grade, the directions given to work on a PowerPoint are well written. These directions could be used by anyone, with any content. Younger learners may need help reading the...

Young scholars explore satellite data and graphing. In this weather data analysis math and science lesson, students analyze NASA satellite data to draw conclusions about geographical areas where precipitation might have happened. Young...

Collaborative earth science groups create a working model of a watershed. Once it has been developed, you come along and introduce a change in land use, impacting the quality of water throughout their watershed. Model making is an...

Links to two different versions of this mapping activity are available. In "The Small Version," youngsters design a town, keeping the water supply in mind. In "The Large Version," they also design a town, but they consider services and...
