Solar concentrators and how they affect the performance of solar cells
This experiment was done to find out how different types of solar concentrators affect the performance of solar cells. The tests were carried out using a parabolic dish covered with a reflective aluminum sheet and a mirror
How different angles of incidence of solar rays impact the performance of a solar cell.
This experiment was done to find out how changing the angle of incidence of sunlight throughout the day impacts the efficiency of a solar cell.
How solar cells are affected by their operating temperatures
This experiment was done to find out how the efficiency of the solar cell will change at different temperature conditions.
Comparing dye-sensitized solar cells
This experiment was done to compare the efficiency of dye-sensitized solar cells with normal silicon based solar cells.
How to make a solar powered hot dog cooker.
A reflective hot dog cooker can be built from a cardboard box, tin foil, and posterboard. Sunlight hits the reflective surface and focuses on the hot dog held in the center. Students can work in pairs or individually if there are enough materials.
Solar Water Disinfection
To determine the relationship between the degree of disinfection of drinking water (infused with a bacteria culture) and varying degrees of opacity of the container
Laser and color filter
This experiment was conducted to determine if the intensity of a laser beam emitted by a laser pointer can be reduced by using colored glass filters. The experiment was done using red, green and blue laser pointers together with red, green and blue colored glass filters.
Sunlight and bacteria growth in aquatic environments
This science fair project was done to ascertain the relationship between the exposure of water to sunlight, and the amount of bacteria in the water. The science fair project experiment was performed on tap water, drain water and water from a lake.
This science fair project was performed to find the best way of collecting and observing micrometeorites. The samples were collected from a roof, the leaf of an outdoor plant and rain water.
At what angle should the blades of a wind turbine be positioned?
This science fair project attempts to ascertain the optimal angle at which the blades of a wind turbine should be positioned in order to generate maximum power.
