My 11 year old is currently producing a project on moons for this term's major assignment - "Space".

We've found some good websites with general information about the number of moons in the Solar System and the number of moons attached to specific planets (although the reported totals often vary from one website to the next), but we're not having much luck tracking down interesting and "quirky" facts about the moons.

The project doesn't have to be particularly detailed, the aim is to get the children to research and share information which isn't generally known about aspects of our Solar System.

Can anyone suggest some resources which might provide information about moons which a group of 6th-graders might find interesting?
