Seasons: What causes summer and winter?

A simple introduction for students that shows how the tilt of the Earth’s axis of rotation is responsible for our seasons. This video makes up part of the Shedding Light on the Sun and Earth series, which covers all the basics of climate science: seasons, winds, weather, hurricanes, and how land masses and oceans affect local and global climate patterns. Each video comes with an activity sheet. The activity sheets include map reading, weather charts, graphing and more. The full series is available on ClickView, Learn360, Classroom Video on Demand, and Safari Montage. Go to our website at for more details and to download the worksheet.
