2. We will calculate the balloon’s altitude by finding it’s angle of elevation and then by using geometry equations to figure out the altitude. We will locate where the balloon is exactly over and stand there. Another team member will then measure the angle of the balloon and the ground. Then we will calculate the altitude using the tangent of the angle multiplied by the distance. Method  H = d(tan Ø)

3. Problems We Might Encounter  Not enough helium  Down winds or some winds of that matter  Balloon might ‘sway’  Having trouble finding the center of the balloon  Errors in angle and calculation measurements  Communication errors

4. Design

5. Graph/Analysis 1 st Flight = red line, 2 nd Flight = brown line, X= balloon line, Y= altitude

6. Conclusion Our intentions were to use 180 feet of string, but we accidentally left it at school. We improvised with a tape measure, and it worked pretty well, because after additional calculations after the flying was over, we determined our balloon altitude calculation would be of by an average of about 25 feet. So that threw us off and made some of our calculations off. We launched our balloon a little late, so we got caught up in the winds, as shown in the graph. After all, we did well and had a fun time. We did get a lot of good calculations too.
