Science Fair Projects - Eyes for Ice

To begin with the background information on the science fair projects - Eyes for Ice, look at Science Experiments for Blind and Visually Impaired.

1. Ice intensities vary depending on locations. Different areas have different ice intensities. The arena ice has maintained constant whereas the road has varying forms of ice. If you compare both they have varying forms of ice intensities. This may affect the performance of the device.

2. Ice intensities vary from one day to other. This is due to varying temperature. It is also important to see whether the device works at different ice intensities.

To investigate the developed product, I have conducted experiments at seven different locations (arena ice, driveway with thin ice, rock surface, road with spot ice, stairs with and without ice, icy snow surface, and garage with no ice.) The above experiments were also repeated at three different days for temperature variations. The results below demonstrate that my product performs well.

Observations on Ice Intensity:

I tested “Eyes for Ice” on three different days. Day 1 had an outside of temperature -20°c, Day 2 had -10°c and Day 3 had a temperature of -15°c. The ice intensity varied depending on the outside temperature. All three days the arena temperature was maintained constant as -13°c. The measured voltage was 3.5 volts when tested at the arena. Same results occurred for the driveway with ice, icy snow, rocky surface and stairs with ice. Whereas, when I tested “Eyes for Ice” on the garage the voltage was low (2.75 volts) and the device did not beep. This was because the garage didn’t contain ice. The garage did have a cold surface ranging from -9°c to -0°c. This is shown in my graph. This validates two factors.

1. My device works properly.
   
2. My device beeps when there is ice and does not beep when there is no ice. I conducted the same experiments on three separate days in same locations. All three days, the ice arena voltage was the same (refer to the graph). This proved that the ice arena was maintained at the same temperature all three days.
