Provides information on what to do after a flood to protect well water from contamination, the testing of private well water, and protecting private well 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...

Use this lesson plan to introduce students to testing water sources for pathogenic microorganisms. Students will learn methods for groundwater sampling to evaluate water quality. Lesson plan includes student worksheets.

Students perform an experiment comparing the impacts of CO2 on salt water and on fresh water. In a short demonstration, students examine how distilled water and seawater are affected differently by increasing carbon dioxide in the air.

This EPA resource provides instructions for using Secchi disks and transparency tubes to measure water clarity.

This site talks about the nitrate and nitrogen forms that can be found and how to test for it. Includes illustrative diagrams and graphs.

This resource from the United State Geological Survey provides data about San Francisco Bay's water quality. Data is displayed in time series plots, vertical profiles, longitudinal sections, space and time contours, and x-y scatter plots.

Choosing two different powders, students will evaluate the properties of the materials and if the materials, when mixed with 50 ml of water, make a mixture or solution. They will examine the difference between a mixture and a solution...

Substances dissolved in water can be present in very tiny amounts that are not visible to the eye. in this lesson students make a solution of food coloring with a concentration of one part per million.

After a discussion of what makes water safe or unsafe, students will visit a local tributary, test the water, and complete tasks concerning the water. This activity is designed for a 6th, 7th, and 8th grade gifted education enrichment...

Read this summary of how water cleaned and tested.

In some part of the world there is not enough fresh water for every use. If things are done differently water re-use can be very effective. Learn here about ways we can change the world. Wastewater, if properly treated can be a resource...

Students perform the first steps that environmental engineers do to determine water quality - sampling and analysis. Student teams measure the electrical conductivity of four water samples using teacher-made LED conductivity testers and...

In this science activity, students investigate the water cycle by testing the water evaporated from leaves (transpiration). They investigate concepts of evaporation and the movement of water through the different states of the water...

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...

Students investigate water cycle processes by testing how cooling affects the rate of condensation of water vapor.

During this activity, students will learn how environmental engineers monitor water quality in resource use and design. They will employ environmental indicators to assess the water quality of a nearby stream. Students will make general...

This site from the National Ground Water Association provides information on ground water, the use of ground water, private water system, well maintenance, and protecting your own well water supply.

Provides information about water quality, contamination in private wells, well construction and pump installation for private wells, a list of laboratories certified to test for bacteria and other contaminants, recommendations for...

This two-month project requires a nearby stream or river to use for testing. Young scholars use river monitoring equipment to conduct water tests, fish observation, insect identification and to collect data related to physical properties...

In this experiment you will attempt to reproduce Galileo's results using the inclined plane. You will test three hypotheses relating to motion on an incline. You will learn to draw a "best fit" or regression line of experimental data....

In this 21-day unit, students are introduced to the anchoring phenomenon-a flameless heater in a Meal, Ready-to-Eat (MRE) that provides hot food to people by just adding water. They complete investigations to collect evidence to support...

This site is useful to find information about dissolved oxygen and the types of tests that are administered to determine the dissolved oxygen level.

This lesson would be used during our nutrition unit when discussing carbohydrates. In this classroom activity students investigate which foods have starch in them by using iodine, as well as investigate the result of iodine and lemon...
