![]() | 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. | ||
| |||
![]() | Collecting micrometeorites ![]() ![]() 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.
