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.
