1. What do you know about the Earth, sun, and moon?
2. What is an orbit?
Assignment #1 (New Unit: Space) Lunar (Moon) PhasesLO: To create a model to compare the orbits of the Earth, moon, and sun.EQ: Why are there phases of the moon? What causes the moon to shine?

What is an orbit? • Orbit: curved path of an object around a sun, planet,
or moon• Earth’s orbit is an ellipse (oval)

• We see the moon because it reflects the light of the Sun. • Reflection: Light from the sun bounces off the moon’s surface.

Half of the Moon is always lit up by the sun. As the Moon orbits the Earth, we see different parts of the lighted area.

The revolution of the Moon around Earth makes it appear as if its changing shape.

As the moon orbits around the Earth, our angle to it changes so it looks like the light is changing shape

This is caused by the different angles from which we see the lighted part of the Moon's surface (where sunlight is reflected). These are called "phases" of the Moon.

The Moon passes through 8 phases during a cycle that repeats itself approximately every 28 days. The phases always follow one another in the same order:
New moonWaxing CrescentFirst quarterWaxing GibbousFull MoonWaning GibbousLast QuarterWaning Crescent

Lunar Phases
• Phases of the Moon: different angles from which we see the lighted part of the Moon's surface.
• There are 8 different phases.
