Creating a Barometer
Have you ever seen a weather forecast on TV? If so, you might have noticed the letters "H" and "L" moving around on the weather map. They are often referred to as zones of "high pressure" (H) and "low pressure" (L). The pressure they are talking about is the atmospheric pressure. Changes in air pressure can forecast short-term changes in the weather. But how do you know if the air pressure changes, or if it is high or low? Scientists have developed an instrument called a barometer that can measure atmospheric pressure. In this activity, you will find out how a barometer works by building one yourself!

This is the second lesson in a series of 2. In this lesson, students will learn about what watersheds are and then take a tour of the school campus looking at it through the lens of being a watershed
Engineers often create small-size models of a new product to test its design. This is especially true with airplanes. Model testing tells engineers how a design responds to different air conditions
Designed for three hour-long STEAM Club meetings for scholars from kindergarten - fourth grade. This lesson plan can also be used for fifth-seventh grade scholars. Scholars will learn about
