Stream Quality Assessment

How does dirty water get clean enough to drink? After viewing a PowerPoint that outlines the process water goes through at a water treatment plant, groups work together to design a chlorination chamber for a treatment plant.

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

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...

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...

In this unit, students will try to improve stream quality and reduce human impacts by taking action.This Advanced Water Quality unit is packaged into three smaller parts: Part 1: Stream Habitat Assessment; Part 2: Macroinvertebrate...

Inspire young conservationists to protect the environment with a short activity on water quality and watersheds. Participants discover the importance of watershed management, learn about water quality problems, and discover possible...

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.

A project based scenario where students research problems and come up with answers to a local water board's concerns over water quality in the watershed. Background information is accessible for the following topics: importance of water,...

Students conduct hands-on fieldwork in order to investigate water quality of a nearby stream. They discuss watersheds and how it affects water quality as well as identify any causes of changes or pollution in the area water before...
