This science fair project is conducted to find out how human activity affect the quality of water in our river channels. The river water will be tested for its acidity, turbidity, as well as for the presence of ammonia and nitrate.
Difficulty: Middle school
Does the pollution in a lake get worse as it gets deeper? Is the water cleaner nearer the surface? Or is it the other way around? This science fair project was conducted to determine how the depth of water can affect the concentration of pollution found in the water. The experiment was done by collecting water samples from a lake at depths of 1 meter, 2 meters 3 meters and 4 meters.
Difficulty: High school
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 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.

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.

Just about everything has potential energy stored in it. The problem is releasing that energy to be able to do some work.A tiny peanut contains stored chemical energy. When we eat them, the stored energy is converted by our bodies so we can do work. We can also use the energy in a peanut to heat a container of water.

How much starch do common foods contain? How can we measure this?
Difficulty: Middle school
