Learning Objectives

1. Understand how the seasons vary over the surface of the Earth

2. Comprehend the role that the tilt of the Earth and the distance between the Earth and the Sun play in driving the seasons.

3. Predict how the seasons would vary for a planet, based on its orbital eccentricity (deviance from a perfect circle) and its axial tilt.

4. Utilize the scientific method to explore and to solve problems.
