A total lunar eclipse is coming on December 21. The NASA web site has a good write up explaining the science behind the event.
High school students might benefit from watching the documentary, If We Had No Moon, which talks about the importance of the moon for human life.
Although the moon has been worshiped since the dawn of human culture, the Bible also has some interesting things to say about it. Students can do a quick word search on Bible Gateway and then try to categorize what the Bible has to say about the moon based on major themes and topics.
