Vacation Package Webquest
The above link is to a pretty cool Webquest. If your team is studying solar systems you might want to check it out. Even if you don't use the resource as it is, there are plenty of parts that you can pull out for use in other ways. There are great links to kid friendly internet resources focused on solar system research. If you're planning a unit on space, planets, or even research itself, this site is worth a look!
