Mr. Comr guides Hudson High School students through a forensic lab investigation to solve a crime involving tire tracks on a baseball field. The lab involves using a caliper to measure tire track width, tire treads, and wheelbase of Matchbox cars, comparing these measurements to evidence. Students create tire track imprints and enter data into a calculator to determine the suspect. The video provides detailed instructions on using a caliper and emphasizes accuracy in measurements.
