In this lesson for Grades 6-8, learners observe the movement of pendulums in order to understand how gravitational forces act and how they affect changes in speed and acceleration of objects. It starts with a brief exploration of Galileo's experiments with pendulum motion, then introduces websites with pendulum simulations, and culminates with a lab in which students construct a pendulum, test its period/frequency, and vary length of the string. This resource comes with warm-up questions, printable student guides, and complete lesson plan.
Editor's Note: We recommend introducing this lesson after students have explored pendulum motion without air resistance. See Related Materials for a link to the "Pendulum Energy Model", a standards-based simulation for Grades 6-9. The accompanying lesson was developed by an experienced middle school teacher.

Covers the Same Topic As Boston University Physics Easy Java Simulation: Simple Pendulum
A robust, yet easy-to-use model that simulates the motion of a simple pendulum. Provides real-time graphs of KE/PE, angular acceleration, angular velocity, and free-body diagrams.relation by Caroline Hall

Is Simulated By Pendulum Energy Model
This is a set of packaged materials for middle school use, all designed for use with the Open Source Physics Pendulum Energy Model. A pendulum simulation is viewed alongside bar graphs that show changing levels of kinetic and potential energy. Air resistance is ignored in this simulation.relation by Caroline Hall
