Barometric Pressure
Recommended for grades 6–12.
Introduction
Barometric (or atmospheric) pressure is one of the measurements that weather forecasters monitor to help predict the weather. Rising barometric pressure usually indicates that fair, dry weather is coming. Dropping barometric pressure usually precedes clouds and precipitation.
Objectives
In this experiment, you will
- Use a Barometer to collect and analyze barometric pressure for 2 days.
- Make observations of current weather conditions.
- Compare your data to weather conditions.
