It has always been a concern of mine that local bodies of water might have fallen victim to chemical pollution as a result of dumping or acid rain. My experiment will allow me to determine the amount of buffer capacity if any is in three local bodies of water.
Difficulty: High school
The purpose of this experiment was to determine if the level of turbidity in water affected the amount of dissolved oxygen. I became interested in this idea because I am interested in water quality and environmental issues. I am interested in water quality because dissolved oxygen keeps fish and other animals alive. The information gained from this experiment could be useful to the fish and wil

The Phoenix metropolitan area, like many large cities, has problems with air pollution at certain times of the year. You can do a simple experiment to determine some of the factors that affect air pollution.
Difficulty: Middle school
The problem with increased CO2 is its affect on global warming. CO2 is not a pollutant but it does trap infrared heat from radiating back into space. This phenomenon is known as the greenhouse effect. This global warming then affects global ecosystems by having effects on water vapor and other climate features. If CO2 levels continue to rise, the results to the planet are difficult to gauge

How can plants be used to measure the level of air pollution?
Difficulty: Middle school
Plants grow by using water and the sun to make food. We are trying to find out if different types of detergents will affect the growth on a plant. This experiment, if done properly, will give us the answers we're looking for.

The purpose of this experiment was to determine which automobile anti-freeze is most biologically safe.
Difficulty: Elementary school
The purposes of this experiment is to compare the amount of Carbon Dioxide (CO2) produced by four different sources of gases.
Difficulty: High school
This simple experiment serves as an introduction to the greenhouse effect. Students can see for themselves the effects of a greenhouse, and relate this understanding to what occurs in our atmosphere.
