What Causes the Seasons

A movie to explain the cause of the seasons. The movie provides pupils with a clear visualisation of the cause of the seasons and they can be encouraged afterwards to describe them to one-another.
The movie can be used as an introduction to the topic (seasons) or as a summary. It is best shown to a group rather than viewed independently, and discussed afterwards.

Slight mistake on this video. He says in the summer the earth is furthest away from the sun. But depends where you are. While it's summer in the northern hemisphere, it's winter in the southern hemisphere. Therefore, for the southern hemisphere, the earth is furthest away from the sun in the winter.

@AllDaySCIfi Actually, the gyroscopic action is not necessary to keep the axis pointed in the same direction during Earth's revolutions. Even with no spinning that axis would not move. (Of course, with no spin it wouldn't really be an axis.) The spin just happens to be the angular momentum that is in place on the Earth. There is no force that would pull the axis any other direction, so the gyroscopic action has no force to resist.

a year does not equal 365 it equals 365.25

@joeisaturtle the earth wobbles

@MERJOATLOR - i mean 365.

@MERJOATLOR- uhhh, ok. It does orbit the sun. It does not move in a flat orbit though. I would like to know what you theory of planetary movement is andwhere we get the seasons and 265 days a year if it does not orbit the sun.

THE EARTH DOES NOT ORBIT THE SUN
