Balloon Experiments
(Note: Background to this page is an aerial shot of the ranch from a balloon)

The balloon experiments are a chance for students to design an experiment from beginning to end and analyze real-life data that they themselves collected. The most common experiment is to measure atmospheric properties (such as pressure and temperature) as the balloon raises in height. The data is then analyzed and compared to the exponential and NASA emperical models for pressure, temperature, etc. vs. altitude. All of the experiments here were done by the physics club and/or APC physics class.

Balloon Experiment write-ups:

Pressure and Temperature changes with altitude (by Patti Pang, et. al.)
