Episode Details

Astronomical events and cycles in the sky had a great influence on society prior to the development of the scientific method, allowing humankind to move beyond a sky filled with superstition and to understand and accurately predict celestial events based on the sun–Earth–moon system. Students will learn what causes the seasons, and they will be able to define terms such as “solstice” and “equinox.” This lesson concludes with what causes one of the most spectacular sights a sky watcher can witness—a solar eclipse.
