  2. BACKGROUND • We as a group chose to take the endeavor of this experiment because it sounded very promising. Earlier in the year we learned how to calculate the rate of free rise by dividing altitude by the time aloft. And when approached by the idea of Balloon Fest our excite flew up to 1000 ft and never came down. Also we knew that with an increase in altitude the air pressure would decrease so we came to the conclusion that we could test the rate of free rise of a helium filled balloon up to 1000ft.

  3. Hypothesis • Because of previous knowledge we think that with a function of increase in altitude the balloon filled with 3200 PSI Helium with a payload of 1000 grams of nylon string will have a faster rate of free rise. • We will test that the balloon will travel faster the higher it gets. Our second test will be to determine to see if the lift decreases because more weight is being added on because of the nylon rope.

  4. DATA/ANALYSIS After completing our experiment we now have collected enough data to graph it. First we tested over 1000 ft in increments of 100 feet. So in the end we had 10 points to plot. The problem we had of the error in our data is that we stopped every 100 feet. So each time the balloon lost it’s initial final velocity and had to start over. It would have been more accurate if we had taken it down to the ground and let it go up in the increments of distance but we didn’t because the nylon rope would have tangled up. The first graph is a lot more accurate because it shows the rate of free rise over a larger distance. And with this data it visually displays our experiment and in turn proves our hypothesis wrong.

  5. CONCLUSION • AVP set out to prove to the world one thing and that is that the free rise rate of a balloon will increase with an increase in altitude. And like cold fusion we failed. They say you learn from your mistakes and we sure did learn a lot! It seems that the balloon basically followed the rules of buoyancy also. Because as if the balloon was underwater the pressure was greater the closer to the ground that it was. So the rate of free rise was faster in the beginning and actually slowed down with an increase in altitude. Completely proving our hypothesis wrong. We learned a lot and know what NOT TO DO next time. But most of all we had fun with science!
