|  | Are carbon filters less effective when the water contains more chlorine?  The purpose of this experiment was to determine whether the efficiency of a carbon filter decreases faster at higher concentrations of chlorine. | ||

| How do phospates affect oxygen levels in water? The purpose of this experiment is to test the effect of a phosphate on the oxygen levels in pond water. I believe that the phosphate will have an effect on the level of oxygen in the pond water. I think that the pond water with only ten drops of the phosphate mixture will have have more oxygen than the pond water with fifty drops of the phosphate mixture. | ||

| How do pollutants affect marine life? 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.

| Are waters in urban areas more poluted than in rural areas? 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. | ||
| |||
| Is the water near animal pens contaminated? The purpose of this experiment is to test the water near animal pens in Batesburg-Leesville for fecal contamination. I hypothesize that the wells located near the animal pens will be more likely to show fecal contamination than the wells that are not near animal pens. | ||
| |||
| How do oil spills affect marine life? To demonstrate what happens in an oil spill, fill a glass bottle two-thirds full of water. Add blue food coloring to make the "ocean." | ||
| |||
| How much pollution can water take before it becomes unsafe? Does this differ between different 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. | ||
| |||
| What is the relationship between turbidity levels in water and the level of dissolved oxygen? 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 | ||

| What factors affect air polution in cities? 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.

| How do Increased CO2 Levels Affect Plant Growth? 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 | ||

Science kits, science lessons, science toys, maths toys, hobby kits,
science games and books - these are some of many products that can
help give your kid an edge in their science fair projects, and develop
a tremendous interest in the study of science. When shopping for
a science kit or other supplies, make sure that you carefully review
the features and quality of the products. Compare prices by going
to several online stores. Read product reviews online or refer to
magazines.
