Instructional Ideas

• Use the video to kick off a unit on inertia or as an earth science brainteaser
• Have paired pupils design an experiment to demonstrate inertia on an object

Classroom Considerations

• Some background information on forces may be helpful for middle school scientists

• This video is hosted on YouTube

Pros

• Reveals the correct answer and explains it simply at the end
• Wrong answers are debunked by explaining the effect that force actually has on Earth, if any

Cons
