1 The Changing Moon Observing, Describing, and Illustrating a Repeating Pattern

2 The Moon The Moon is essentially round, but it is a lot smaller than the Earth.

3 The Moon The Moon travels around the Earth. It goes around about once every 28 days. We only see the part of the Moon that is lit by the Sun. So, sometimes we see the whole Moon and sometimes we only see part of the Moon.

4 There are 4 basic moon phases, or shapes, that we see during the month: 1.New 2.First Quarter 3.Full 4.Third Quarter The phases are a repeated pattern.

5 The Moon The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky.

6 The Moon From Earth, we see the Moon grow from a thin crescent to a full circle (or full moon) and then shrink back to a thin crescent again before vanishing for a few days. The Moon doesn’t really “vanish”- it just looks as though it is not there.

7 The Moon The phases, or shapes, follow a specific sequence as the Moon orbits, or travels around, the Earth one time.

8 Observing, Describing, and Illustrating the Moon Observing: We can look into the night sky and see the Moon. We do not need a telescope or any other science tool to see the Moon.

9 Observing, Describing, and Illustrating the Moon We can sometimes see the Moon during the day.

10 Observing, Describing, and Illustrating the Moon The lit part of the Moon always points the way to the Sun. Sun Moon
