This science fair project was conducted to study the effect of gasoline fumes on plants. The testing was done by placing plants beside a gasoline-filled container for different periods of time and temperatures.
Difficulty: Middle school
This science fair project was done to study the effectiveness of using natural plant extracts to control the growth of weeds. The science project experiment was performed using different concentrations of juice extracted from Bay laurel leaves.
Difficulty: High school
This science fair project was done to observe the effect of using activated carbon to neutralize the effect of pesticides. The science project experiment involved using flies, the pesticide malathion and different concentrations of activated carbon.

Global warming occurs when greenhouse gases in the planetís atmosphere trap and retain heat, altering the earthís climate. Plants are affected by higher greenhouse gas levels, even though they consume carbon dioxide and sunlight to make energy. This science project encourages students to compare the growth of a plant under natural conditions with a plant that has been exposed to extra carbon diox
Pesticides are necessary to keep our agricultural plants safe from insect infestation. Natural pesticides are increasingly preferred, as they reduce the number of chemicals that are released into the environment. In this experiment, you will examine whether biopesticides are as effective as their chemical counterparts.
While most of us do not give much thought to water quality, serious aquarists are keenly aware of the importance of maintaining water quality. But while aquarists are careful to maintain ph, nitrates, and ammonia levels, many do not give the same attention to the level of dissolved oxygen (DO). An understanding of the relationship between temperature and DO is the subject of this science project.
This science fair project was conducted to determine the effect of pollution on the stomata density of coniferous trees. The science fair project was done using samples of pine tree leaves from 3 locations with different levels of traffic flow.

The purpose of this experiment was to determine whether the efficiency of a carbon filter decreases faster at higher concentrations of chlorine.
Difficulty: High school
The purpose of this experiment was to discover how pollutants of varying concentrations harm aquatic life. I became interested in this topic when looking through a list of ideas. I thought it would be interesting to see what pollutants were the most harmful to aquatic environments. I am also concerned about pollution of our water because I enjoy many water sports including skiing and swimming.
Difficulty: High school
The purpose of this experiment was to determine whether the level of certain chemicals in the tributaries to the Yakima River was different in the rural area of the Umptanum Creek compared to the urban area of the Wenas Creek.
Difficulty: High school
