More than 300 years ago, Robert Hooke identified a proportionality that has remained a fundamental concept to physicists and engineers to this day. After the activities, the lesson concludes with a stress-strain quiz to assess each student's comprehension of the concepts. Through the lesson's two-part associated activity, students 1) explore Hooke's law by experimentally determining an unknown spring constant, and then 2) apply what they've learned to create a strain graph depicting a tumor using Microsoft Excel®. First they learn the governing equations, then they work through several example problems, first individually, then as a class. Students are introduced to Hooke's law as well as stress-strain relationships.
