Barometric Pressure Lab

For this lab, we used a balloon, a bowl, and a straw to create a barometer. We then kept track of the straw's movement using a ruler in order to create a measure for atmospheric pressure. When atmospheric pressure is high, we often experience warm clear sunny days, while low pressure systems are usually associated with cloudy and stormy weather. We discovered this by observing our barometer through a variety of conditions, sunny days and stormy days. The barometer measured the air pressure because the balloon would expand or contract due to the variation of pressure caused by the systems. However, the data used in Excel to create the graph and chart came from Dr. Rood.
