Using Hooke's Law to Understand Materials

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups predict the stiffness of different springs prior to testing them.
