Unformatted text preview: University of Florida Chemistry Outreach Program Barometer in a Bottle Estimated Time: 30 mins. + 15 mins. clean-up, observation could be expanded to occur over several days (supervised by teacher) Topics: Atmospheric pressure Introduction: Atmospheric pressure refers to the weight of air above any given point. Areas with low atmospheric pressure have less air above them, and measurements that read low atmospheric pressure (example: toward the top of mountainous regions) indicate that the total “mass” of the air above it is lesser than what would be observed if measurements were taken in a higher atmospheric pressure area (such as in valleys or at sea level). A metaphor for explaining atmospheric pressure is to imagine the latter to be like layers of blankets; the higher up you are in the atmosphere, the fewer blankets you have. More blankets are heavier, and as a result translate into higher atmospheric pressures. The study of atmospheric pressure is important because it can allow translate into higher atmospheric pressures....
