This Double Pendulum interactive also includes:
What's better than a pendulum for studying motion and periods? A double pendulum! Young physical scientists use an interactive to explore pendulum motion—times two. The resource boasts a host of parameters to change and a running graph of angle versus time to analyze.

Instructional Ideas
- Split the class into three groups, then have each group individually test either rod length, starting angle, or the mass of the ball; compare results as a class when everyone has finished
- Direct pupils to make focused observations of how changing each parameter affects the period of the double pendulum
Classroom Considerations
- Avoid changing all of the conditions at once until learners are comfortable with making observations of the pendulum's motion
Pros
- Users can save their data and compare them with the results of other trials
- The simulation is easy to use without much oversight
Cons
- The ? icon referred to in the About tab is missing from the interactive
