Fact: the moon hangs in the sky (or circulates the Earth if you would like to be completely correct), every night, and in fact every day as well. Fact: it cannot be seen every night, depending up on when it rose and fell in your region, as well as depending upon the weather in your area. Fact: it is the same size and shape at every time, but the shadow of the Earth makes it appear to be in a crescent shape, and the distance from the Earth makes it appear larger or smaller. One example of it appearing larger in the night sky was on June 23, 2013. Did any of your students witness this?
This infographic shares information about the upcoming Supermoon (since this infographic was created before the Supermoon). According to this infographic, it was about 30,000 km (ask your students to figure out how many miles that is), closer to the Earth than on an average day. There are also about three to four Supermoons per annum.
Hypothesize with your students why this Supermoon is exceptional, if there are several each year. Also, how does it affect the tide? It is a fact that the moon affects the tide, but what is it about the moon that affects the tide. Have your students explain this phenomena in their own way, by drawing, video, using words, or any way that makes sense to them and may help other students understand.
