Description:

This lesson demonstrates the link between the tilt of the Earth's axis to the plane of the ecliptic and seasons of the year, length of day, effectiveness of sunlight, and polar day and night. It discusses how the inclination of the Earth's rotation axis causes seasons of the year, by varying the length of the local day and the angle at which the Sun's rays arrive on the surface of the Earth, and to recognize that seasons in the southern hemisphere (at middle latitudes) occur at opposite parts of the year from seasons in the US and Europe. The student will also realize that the seasons in the middle-latitudes in US and Europe are quite different from seasons experienced near the equator and also know about the polar day, when the Sun never sets but just marches around the horizon, and the polar night, when it never rises.
