Barometer Lab

We conducted this lab to examine the nature of high and low pressure systems. By creating the device, and examining the readings, we were able to understand how, and in what ways, weather pressure systems work. We constructed the device by sealing a rubber balloon to the top of a bowl and taping a straw to the top of the latex surface.
