Water Quality Image Map

Specific Teacher's Pages for Each Unit:
Module 1: Measuring Mass, Fluid Volumes, and Concentrations

Module 2: Measuring Temperature and Its Effects on Water Quality

Module 3: Measuring Dissolved Oxygen and Its Effects on Water Quality

Module 4: Measuring pH and Its Effects on Water Quality

Module 5: Measuring Nitrates and Their Effects on Water Quality

The Units

This module will focus on five different measurable properties of water. Determining the quality of water involves more than observing it's color and sensing it's odor. The properties or characteristics of water in a river or lake can be affected by man, weather, time, and animals or plants within the water.

Units can be presented in any order.

The standards targeted in each module are based on the Texas Essential Knowledge and Skills (TEKS).  As a convenience, these are included in the teacher notes to each unit.

A Note About Hyperlinks:

One problem that we cannot help you with is "link rot."  As you are probably aware, links on the Internet become useless at an alarming rate. One study that monitored educational sites for a little over 6 months found that nearly one fifth of the Web sites that were linked disappeared. The dot-com sites had the highest attrition rates (40%), followed by ".edu" sites (18%) and ".org" (15%).  We emphasize ".gov" sites on the assumption that the information there may be more reliable and that the sites may be more likely to survive and be maintained. Even in such a case, many Web-site managers have an unfortunate tendency to re-organize (and re-address) their Web pages. If a site that appears to be dead is critical for your purposes, it can pay to contact the Web-master (they usually put a link to themselves on the home page of the site).
