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...

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...

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...

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...

A professional and comprehensive presentation on Chesapeake Bay water quality is in store for your ecology class. If you live in the Chesapeake Bay region and want to get learners involved in conservation efforts, this slide show will do...

Written as field trip preparation to Gateway National Recreation Area, this resource is also appropriate for any class that is studying the impact of human activity on the environment. During the first activity, learners identify...

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...

Here is a document full of teaching notes on water quality and bodies of water that you can use in your ecology curriculum. It has information specific to the Hudson River area, but can easily be adapted to any local body of water....

A scenario and background information are provided for two different open-ended experiments that experienced chemistry classes can perform toward the end of the school year. In the first, they design a method for testing flakes of paint...

Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a...

Learners monitor a local creek. In this environmental water lesson, students conduct an environmental study of a local creek by monitoring the temperature and water quality over a period of time, then submit data to the Global Water...

In this science instructional activity, students use the diatoms present in water in order to test water quality and perform data collection and interpretation.

Young scholars examine the factors the affect water quality, and allow for animals and plants to live. They look at how engineers apply water quality information when making stream modifications in order to ensure drinking water quality....

Students explore ways to protect the earth.  In this environmental issues and technology lesson, students investigate the water quality in their community and compare their findings to the water quality in other geographic...

Sixth graders conduct a variety of assessments at a local stream to determine if it is a suitable habitat for salmon. They measure temperature, tubidity, dissolved oxygen, pH levels, bacteria and nutrients. In this unit, 6th graders work...

Students examine how watersheds work and determine the difference between point and nonpoint source pollution. They research management practices to reduce pollution and investigate how everyone can participate in reducing water pollution.

Pupils investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-activity series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Students work as a team to gather organisms from a stream to evaluate if the water quality is excellent, good, or fair to poor.

Students identify important aspects of water quality such as slainity and turbidity. They test two of the water quality parameters and determine the quality of the water. In addition, they construct two sets of graphs based on data...

Students investigate a fish kill occurrence, the Lake Iluka simulation. They examine what would happen if a fish kill happened today in their watershed area? what type of problems it might cause? They also discuss in groups any specific...

Students explore the water qualities in Texas. They evaluate the water quality of six different samples by observing and smelling them. They present a list of the cups that contained good water quality based on their observations. They...

Students are presented with a hypothetical situation to investigate the water quality of the James River. They are given data to analyze and put into the graphic organizer that is included to help solve the problem. The instructional...

Seventh graders discuss water quality, water availability and water resources and how water is used in the world around them. They view a video on water quality then test for pH, temperature and dissolved oxygen to indicate water quality.
