In this activity, students will create and analyze graphs and investigate how temperature and pressure are related.

Charlotte Motor Speedway is a 1.5 mile track banked at 24°. The October 2009 pole qualifying speed, posted by Jimmie Johnson, was 192.376 mph. The Charlotte October race can be heavily influenced by the weather and temperature change from afternoon into late evening. Cooler conditions deliver more air to the engines. We will investigate these relationships just like the crew chiefs and engineers do.
