In this lesson, we will learn how to describe how the density and pressure of Earth's atmosphere change with height above the ground.

Students will be able to

describe what the atmosphere is,
recall what is meant by the terms air column, pressure, and atmospheric pressure,
recall that the bar is a unit of pressure,
recall the value of atmospheric pressure at sea level,
recall that atmospheric pressure changes with height above sea level,
recall that atmospheric density changes with height above sea level,
recall that pressure can be used to measure altitude with devices such as an altimeter,
understand isobar diagrams,
draw isobar diagrams,
recall that a barometer is a device that can be used to measure pressure,
recall that hot air rises and cold air sinks.
