Admit it. You've wondered about it, too. And so have your students. Some were brave enough to ask while others were satisfied with their imaginations.
Not any more. Watch this short video of an astronaut as he explains (very nicely) how that is handled. I think he's talking to some middle school students, but you never see them.
So, when you talk about life in zero gravity and this subject comes up, show this video. You won't look at shooting stars the same way again, I can tell you that much. :-)
