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.
Comparing the effectiveness of a light sensor and a touch sensor
This experiment was conducted to compare the effectiveness of using a light sensor and a touch sensor on a conveyor belt. The experiment was done by using a light and touch sensor to count the number of boxes on a conveyor belt.
The efficacy of bioethanol fuel
This science fair project was done to compare the performance of bioethanol against other types of fuel. The tests were done by comparing the energy produced, as well as the burning time of bioethanol, kerosene, diesel and gasoline.
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.
Soil fertility and conductivity
This science fair project was performed to observe the relationship between soil type and soil conductivity. The testing was done using sand, clay, loam and loam mixed with fertilizer.
Surface tension of water
This science fair project was conducted to observe how adding salt to water and increasing its temperature can affect the surface tension of water. The experiment was done by adding grains of rice to a piece of aluminum foil floating on water of varying temperatures, i.e. of 15°C, 25°C, 35°C, 45°C and 55°C.
Viscosity of sweetened water
This science fair project was conducted to determine how viscosity of water increases when sugar is added. The tests were done by adding and mixing 20grams, 40grams, 60grams, 80grams and 100grams of sugar to a cup of water.
Effect of propeller size on thrust produced
This science fair project was done to determine how the size of a propeller will affect the amount of forward thrust produced by it. The experiment was done using 4 different propeller sizes.
How do magnetic fields affect the rate of flow of water?
This science fair project investigates how the magnetic field emanating from a permanent magnet will affect the rate of flow of water through a narrow passage. The experiment will be done using salt solution and tap water, with a magnetic field as well as without a magnetic field.
How does the bounciness of a golf ball affect the distance that it will travel?
This science fair project was performed to find out if relatively bouncier golf balls are able to travel further than less bouncy ones. The tests were done using 3 brands of golf balls.
