This interactive lesson for Grades 9-12 demonstrates how the motion of the Foucault pendulum proves that the earth is rotating. It blends an animated tutorial with informative text to expand student understanding of motion and gravitational force. It was also designed to address the common misconceptions that the earth's gravity does not extend beyond its atmosphere or that it is caused by the atmosphere. The package includes student activity sheet with answer key for teachers.
See Related Materials for a short video from Teachers' Domain that further explores Leon Foucault's famous pendulum experiment and an online tutorial from PhysClips that provides more advanced information about the physics involved.

3-5: 4B/E2bc. The rotation of the earth on its axis every 24 hours produces the night-and-day cycle. To people on earth, this turning of the planet makes it seem as though the sun, moon, planets, and stars are orbiting the earth once a day.
9-12: 4F/H2. All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.
9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.
