Science on the SPOT: Watching the Tides

 Watching the Tides Educator Guide ( pdf ) A resource for using QUEST video in the classroom.

Ocean tides rise and fall twice a day, influenced by the gravitational forces of the sun and moon. Studying tides' rhythmic movements helps us understand both the ocean and the cosmos. Astronomer Ben Burress explains how tides work, and QUEST visits Crissy Field in San Francisco to see the oldest continually operating tidal gauge in the Western Hemisphere.
