Lunar Phases

If you have ever observed the Moon for more than a night or two, you will have noticed that its appearance changes and does not always look the same. Why do you think this this the case? Take a few moments to view the video discussion prompt Moon Movement from eMediaVA℠.

Once you have viewed the video prompt, answer the question that it provides in the course discussions area. It is fine if you do not know the technical reasons for explaining what you see; however, you need to put forth your best hypothesis in your initial post. Then, return to the topic several times over the next few days to read your coursemates' posts. Reply to at least two of them, making sure to ask questions and encourage further conversation.
