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.
What is bioremediation and what conditions are required for it?
The purpose of this activity is to develop a test tube model of an oil spill in order to experiment with conditions needed for bioremediation.
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
Examine how much Carbon Dioxide is produced by different gas sources? This helps us understand the impact of these gas sources on global warming.
The purposes of this experiment is to compare the amount of Carbon Dioxide (CO2) produced by four different sources of gases.
Is soil a type of electrical system?
This very interesting experiment will help you prove whether soil functions as an electrical system.
How soil management affect soil quality?
Soil is one of our most precious natural resources, as it integrates all parts of the ecosystem. It provides a medium for plant growth so that we can have food, clothing, and other materials. Soil filters water, decomposes waste, stores heat, and exchanges gases. Soil is alive- it is the home to billions of micro- and macroscopic organisms. It is a material used for construction, medicine, and art
