Method
Experiment -Use two stations to measure balloon
altitude and the effect of the weather on the
tether and altitude at intervals of 100
ft. -Compare the altitude of the balloon to the
amount of tether let out.

• Let out 100 ft. of tether hold for about one
  minute and take measurements.
• Do so again at 100 ft. tether intervals until the
  balloon reaches 700 ft.

3
Hypotheses

• For every 300 ft. of tether let out, the altitude
  of the balloon will be 200 ft.
• The amount of tether let out will be
  significantly larger than the actual height.
• The ratio of tether let out and measured altitude
  will change depending on wind and weather
  conditions.

Data Analysis
This is the graph of the altitude of the ballon
versus the amount of tether that was let out. As
the wind picked up in the middle the ratio of
altitude to tether fell, indicating that the
balloon had been blown to the side.
5
Error Analysis

• We think there are three main sources of error
  adding to an error of /- 30 ft
• The tether length was accurate to about 1, which
  is about 7 ft at full tether extension
• The vertical angles were accurate to about 1
  degree which can cause a height error of up to
  14 ft
• The GPS was accurate to about 7 ft., but this
  does not have significant effect on the data
  calculations.

Conclusion

• Over the course of our experiment, we saw
  initially no wind, then significant wind, and no
  wind again at the end.
• Our first hypothesis was incorrect.
• Our second hypothesis was correct for the middle
  part of the experiment.
• Our third hypothesis was correct in that the wind
  did have a serious effect on the amount of tether
  let out which changed the altitude.
• In comparison to the data from Kashyyk who did
  the same balloon, we found that there was a
  difference of about 50 ft. in height over the
  course of the experiment. Their measurements were
  a little low whereas ours were a little high.
  This supports our postulate of /- 30 ft. error.
