How Does Air Temperature Affect Race Car Tires?

Is Lesson Plan Physical Science Middle School

Sensemaking Checklist

Lesson Overview

NASCAR race car tires require more air in cooler temperatures and less air in warmer temperatures. Middle school students identify this puzzling pattern in data and want to know why! Using readily available materials, students investigate the effect of air temperature on air particles in a closed system. Tracking the flow of energy into and out of the system under study helps students explain why adding air to car tires on a cold race day can make the difference between winning and losing a NASCAR race.
