The data we took in the above-most picture is from a tractor running, with the sensor about 5 feet away. The sensor only can sense up to 100 dBA, so the jumps in the graph are higher than they seem. If one is exposed to ~100 dBA, their ears will be damaged after ~15 minutes. The tractor emitted over 100 dBA of sound at points, but only for a second, so we weren't in danger. At other times it emitted around 90 dBA of sound, which requires 30 minutes to harm your ears, so we were fine when it comes to our ears being damaged or not. ------------------------------------------------------------------------------------------------------- Light Test
Hypothesis: If we record the light values around the room with a light sensor, then we will find that the brightest part of the room is the area closest to the windows & the darkest part of the room is towards the back of the room near us because the sunlight should give light to the floor near the window & the back of the room has little to no exposure to sunlight.
According to the video & our data, the lightest part of the room is the middle lane of the computers closest to the door. The darkest part of the room is the middle of the middle lane of computers. ------------------------------------------------------------------------------------------------------- Hearing Test Hypothesis: If we test two students & two teachers in the school by how how pitched of a sound they can hear, we will find that the students can hear better than the teachers. Data: Nick = Can hear until max Hz possible (9440 Hz) (9 Clicks) Mr. Croke = Can hear until 8440 Hz (8 Clicks) Jordan = Can hear until max Hz possible (9440 Hz) (9 Clicks) Mr. Ramos = Can hear until max Hz possible (9440 Hz) (9 Clicks) ------------------------------------------------------------------------------------------------------- Storm Test Hypothesis: If we simulate a lightning strike, then we will find that the sound will come after the light. Speed of Light: ~300,000 km/s Speed of Sound According to Our Data: ~.35555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555 km/s Distance of the Storm: 2 miles (3.21869 km) Time it took for Sound to Travel: 9 seconds ------------------------------------------------------------------------------------------------------- Reaction Test Hypothesis: If we setup a program that will check how fast people's reaction times are, then we will find that the younger the person, the faster the reaction time will be. Data: Jordan = 233 ms Jillian = 203 ms Nick = 253 ms Scott = 233 ms Conclusion: Our hypothesis was wrong, the younger age didn't affect the reaction times too much.
