Hooke's Law: The Rest of the Story
Students study Hooke's Law. They explore the linear behavior of a spring as it is pulled downward and understand that stretch on a spring is directly proportional to the force applied to the end of the string. Students create scatter plots, calculate slopes, and discuss positive and negative slopes.https://education.ti.com/en/activity/detail/hookes-law-the-rest-of-the-story
Millikan Oil Drop Experiment Simulation
Students run a simulation on the TI-83+ or TI-84+ graphing calculator to perform a variation of the Millikan Oil Drop Experiment.
