Understanding How a Barometer Works with High and Low Pressure Systems

In this Earth Science lab, students will create their own homemade barometers using a canning jar, a balloon, and a straw. The barometers can show low and high-pressure systems. After they build their barometers, students will complete a daily log, by measuring the height differences of their barometers. They will determine rising and falling barometers. Students will also observe the weather that is currently outside.

When their observations are complete, they will answer questions as to how a barometer works and how it can be useful in determining high pressure and low-pressure systems.
