Students examine the YSI and the water properties that it measures. They identify the different properties of water pH, DO, temperature, turbidity, and salinity and determine why it is important for them to test these parameters.

Students identify at least three common repercussions of developing water front property on water quality. They describe three sources of water pollution. They research the organism striped bass and observe it if striped bass is available.

Students develop a process for analyzing collected bayou data. They find the mathematical relationships among various biological factors. Students, work collaboratively using technology in their data analysis.

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

Students examine water quality on a nearby stream. They collect water samples and test for various factors, including any contamination from the treatment plant, and present their information in a Powerpoint presentation.

Eighth graders analyze different water samples given to them by their teacher.

Students examine the effects of nitrates and phosphates on the dissolved oxygen levels in different water sources. In this series of 3 lessons, they consider the reasons for nitrate and phosphate level increases and their effects on...

Students examine how they affect water quality of those who live downstream after identifying rivers and river basins in Kansas.

Learners identify major rivers in Kansas, identify the direction which they flow and identify tributaries of the Kansas River. Students examine what occurrences upstream influence water quality downstream.

Join Anita, Dennis and Simon as they take a field trip to Willow Creek. This visit to the creek is slightly different than their first encounter there--discover why by reading this interesting tale!

Learn about the safety of drinking water, find information on agencies that oversee our water, and gain access to the current drinking water standards and regulations.

Wells are extremely important to all societies. Find out how wells are dug today and peruse the list of the different types of wells and the methods used to dig them. Click Home to access the site in Spanish.

Activity shows the link between land use activities within a watershed and water quality.

This activity introduces students to the complex chemistry of estuarine water. Students investigate how chemical and physical water quality factors-pH, temperature, dissolved oxygen, and salinity-change and interact over varying time...

In this activity, students investigate a large watershed, look for sources of pollution in the watershed, and study the impacts of a rain storm on a watershed and estuary, without going on a field trip. Students investigate the nature of...

In this inquiry, students engage with mapping data to determine what kind of land coverage is contributing the most to harmful algal blooms in the Chesapeake Bay Watershed. Click on the link for teacher resources for teaching guides and...

This inquiry is intended to provide students with practice developing investigable questions that need data, and specifically large datasets, to be answered. Click the teacher resources link for teaching guides and student handouts.

In this activity, students' will use a pH sensor to check and compare the pH values of various water samples. They will understand the meaning and effect of pH and factors that affect pH.

How can you learn to build your own watershed? This site features an activity to illustrate the basic properties of a watershed. Don't miss out.

Directions for doing a simple simulation that shows how pollution spreads through groundwater sources.

This US Geological Survey site briefly discusses the basics of why pesticides are increasingly found in our ground water. Click Home to access the site in Spanish.

After analyzing samples of water from local lakes, students will perform tests on water from two locations, compare the results, and complete a lab report. They will then examine maps to determine factors that may have had an impact on...

After investigating the health of waterways in their community, students can undertake this activity where they participate in a community cleanup.
