This lab used household items to create a barometer. The
homemade barometer consisted of the following materials: a balloon, a small
glass bowl, a small piece of tape and a straw. The balloon was cut in half ant
stretched over the top of the bowl. Then the straw is taped in the center of
the balloon membrane. Periodically the height of the tip of the straw was
measured and recorded with the affiliated pressure published by the weather
channel.
The barometer was very simple to construct, even though
stretching the balloon was rather annoying. The calibration process required
the use of excel to calculate a trend line. This lab showed how easy it is to
make a homemade barometer, and showed what steps were necessary to calibrate
it. Plotting the data gave me with a better understanding of excel and how to
properly format the tables and graphs. The additional exposure to excel should
help me present technical findings in a more professional manner.
