We home school as well. This is our first year, and have not started the bee's yet (only a few more weeks). But I can tell you my girls are excited about it. They have been involved with a lot of the things. We will have window's on some of ours, but after a while the windows may not be useful as the comb get's built up. So I plan to try and use a camera as well.
When our kids were little we always went to childrens museums. I cannot remember were it was but there was one that had a hive built into an outside wall of the building, with a big window on the inside of the building, that was awesome. The bees could not get to you, as thier only entrance to the hive was from outside.
