Worksheet Description

This worksheet is designed to engage students with the practical application of reading and interpreting a mercury barometer, which is an instrument used to measure atmospheric pressure. Each section of the worksheet features a different dial of a barometer showing varying atmospheric pressures indicated by the position of the indicator needle and the set hand. Students are tasked with writing the specific readings of both the indicator needle and the set hand for each barometer. They must also describe the pressure changes based on the movement of the needles compared to a base reading, enhancing their observational skills.

The primary goal of this worksheet is to help students understand how atmospheric pressure is measured and how it can change over time. It teaches students to accurately read and record measurements from a barometer, an essential skill in weather prediction and scientific observation. By analyzing the direction of the needle movements, students learn to interpret whether the atmospheric pressure is rising, falling, or remaining stable. This exercise not only improves their data recording skills but also their ability to predict weather changes based on pressure readings.
