The document describes how a barometer works and the relationship between temperature and air pressure. It discusses setting up barometers in jars under lamps and having students observe what happens to balloons in the jars as the temperature changes. The students note that warmer temperatures cause the air pressure to increase and balloons to rise in the jars, while cooler temperatures decrease the pressure and cause balloons to shrink.

- 2. Lesson Objective: •Students will describe how a barometer works. •Students will state the relationship between temperature and pressure CT Standard: • Explain how changes in temperature, pressure, moisture and density of air create weather. Barometer Basics
- 3. Using ActiVotes for Pre-test
- 5. What happened with the barometers? What caused the balloon to rise and shrink?
- 6. What causes air pressure? Student A: “The temperature helped increase and decrease the pressure inside the jar.”
- 7. Showing evidence of the barometer change Student B “Cold air will have a heavier air mass than hot air.” Student C “In the jars under the lamps the balloons are rising.”
