Ascend to 30 km, collecting data regarding temperature, air density, sound
Compare air density to sound to confirm expected relationship
Compare amounts of Carbon dioxide with sound data
Hypothesis: air density goes down=frequency increases, amplitude decreases
Large amounts of carbon dioxide result in new recorded frequencies
Why? Use sound as means of detecting gas
-As air density decreases due to altitude, frequency of sound will increase
-As air density decreases, amplitude will decrease
-Pitch will decrease with an increase in carbon dioxide percentage in ambient air
BalloonSat is overweight Difficulty extracting sound data due to
outside noise Identifying a correlation between carbon
dioxide levels and sound data
Requirement Result
BalloonSat internal temperature shall remain above -10 degrees Celcius
Confirmed by cold test
BalloonSat shall not exceed 850 grams
BalloonSat is currently overweight (app. 940 g)
Budget shall not exceed $300.00 Budget is currently at $283.97
Materials/Components (HOBO, foam core, temp probes, flight string/tube, camera, scientific experiment, flag,heater)
All necessary components are accounted for
