5 ) Use mathematics to explain the relationship of the seasons to the tilt of Earth's axis (e.g., zenith angle, solar angle, surface area) and its revolution about the sun, addressing intensity and distribution of sunlight on Earth's surface.

Subject: Science (9 - 12)
Title: Solar Angles and the Unequal Heating of the Earth

In this activity, students will model how the directness of sunlight affects the heating of Earth’s atmosphere at the equator. Students will demonstrate that Earth’s shape has a direct effect on the unequal heating of the atmosphere. The students will discover how the tilt of Earth’s axis affects the amount of sunlight that reaches different regions of the earth’s surface thus causing different seasons.
