Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead,...

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...

Students examine how water is treated prior to becoming available for human consumption. In this water treatment lesson, students conduct an experiment in which they filter water. Students formulate a hypothesis, test, analyze data, and...

Students build a model of a water system from the source to users and read and interpret a water meter.

Students create a water filter according to given criteria. I this chemistry lesson, students evaluate the importance of water in their lives. They develop a book or brochure on the water treatment process.

Students construct a still to turn seawater into drinking water. They estimate the cost of distilling it. They investigate ways to make the conversion more efficient. They track the source of their home drinking water and make a map of...

Students investigate the meaning of potable water and water reuse. They define water quality and quantity problems. They complete worksheets, a quiz and design a poster.

Students explain the processes involved in the cleansing and purifying of surface water. After a lecture/demo, students engage in an experiment that illustrates how water is cleansed before we drink it.

In this unit of lessons, students examine water quality issues. They discover ways they can conserve water and practice making drinkable water from water desalination.

Students use the Internet to study how water is treated to make it safe to drink. They use a tutorial on the U.S. Environmental Protection Agency's website to gain this information. They complete a worksheet for the assessment portion...

Eighth graders examine what materials cause water hardness and the relative measure of water hardness in a two part lab activity. In part one, 8th graders add an assigned soap test solution to eleven different test tube solutions in...

Fifth graders discuss the importance of water quality for humans and fish and make predictions about what happens to water that is polluted. In small groups, they conduct experiments to compare and contrast water that is unpolluted and...

Students examine porosity and permeability and relate these concepts to groundwater flow. They use simple materials to conduct a porosity experiment and use the information to understand how environmental engineers decide on the...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Students view a demonstration of how groundwater flows and define several related vocabulary terms. They complete a worksheet, participate in discussion and make a poster.

Lab groups set up an experiment to observe what happens over time in collected pond water when fertilizer, representing pollution, is added. This website does not include student lab sheets, but background information, materials, and...
