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.

AAAS Benchmark Alignments (2008 Version)

4. The Physical Setting

4F. Motion
  • 6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
4G. Forces of Nature
  • 3-5: 4G/E1. The earth's gravity pulls any object on or near the earth toward it without touching it.
  • 9-12: 4G/H1. Gravitational force is an attraction between masses. The strength of the force is proportional to the masses and weakens rapidly with increasing distance between them.

12. Habits of Mind

12C. Manipulation and Observation
  • 6-8: 12C/M3. Make accurate measurements of length, volume, weight, elapsed time, rates, and temperature by using appropriate devices.
12D. Communication Skills
  • 6-8: 12D/M1. Organize information in simple tables and graphs and identify relationships they reveal.
  • 6-8: 12D/M2. Read simple tables and graphs produced by others and describe in words what they show.
  • 6-8: 12D/M6. Present a brief scientific explanation orally or in writing that includes a claim and the evidence and reasoning that supports the claim.

Common Core State Standards for Mathematics Alignments

Measurement and Data (K-5)

Geometric measurement: understand concepts of angle and measure angles. (4)
  • 4.MD.5.b An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

Science NetLinks: Exploring Pendulums:

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.
