For this assignment, you will develop and use a model of the Earth-Moon-Sun system to describe the cyclic patterns of lunar phases and eclipses of the Sun and moon. You also will model and illustrate how the tilted Earth rotates on its axis, causing day and night.

You will then create a multimedia presentation featuring your models.

Background Information
Earth rotates on its axis, which causes day and night. Earth also revolves around the Sun. The path Earth follows is called its orbit. It is shaped like an oval. The moon orbits Earth in the same way. It revolves around Earth and rotates on its axis in 27.3 days. Because it rotates and revolves around Earth in the same time frame, a “day” and a “year” on the moon are the same, and the same side of the moon always
faces Earth.
As Earth revolves around the Sun, the seasons change. Earth is actually closest to the Sun when the Northern Hemisphere experiences winter. The cause of the seasons is actually Earth’s tilt. Summer in the Northern Hemisphere occurs when the north is tilted toward the Sun. The Sun's rays hit Earth more directly, which heats the surface. During the Northern Hemisphere’s winter months, the north is tilted
away from the Sun. So, the Sun's rays hit Earth less directly. When the Northern Hemisphere experiences summer, the Southern Hemisphere experiences winter. When the Southern Hemisphere experiences summer, the Northern Hemisphere experiences winter.
The moon has different shapes at different times of the month that are caused by the relative positions of the moon, Earth, and the Sun. Half of the moon is almost always lit by the Sun, but since the moon revolves around Earth, we see it from different angles. The phase of the moon you see depends on how
much of the sunlit side of the moon faces Earth.
The moon’s orbit is tilted in comparison to Earth’s orbit around the sun. The moon’s axis tilts at about 5 degrees to the plane of Earth’s. Because of the tilt of both the moon and Earth, the moon does not often get in Earth’s shadow, and the moon’s shadow does not often cover Earth. A solar eclipse happens when
a new moon blocks our view of the Sun. A lunar eclipse occurs at full moon when Earth is directly between the moon and the Sun.
