2. Overview Purpose: Our purpose is to find the variation of air resistance by observing the current through a DC fan motor when exposed to air resistance and pressure change with altitude. Hypothesis: We believe that as the altitude increases, the air resistance decreases, which will bring the current down.

3. Our Experiment:  Gondola  Fan Circuit  Lab Pro  Current/Voltage Probe  1000 feet

4. Trial 1

5. Trial 2

6. Trial 3

7. Conclusion We discovered from our testing that as the gondola rose and the altitude increased, the air resistance generally decreased, and likewise the current through the fan decreased. Thank You … Questions
