I have to teach philosophy to 8 and 9 year olds tomorrow, how can I do this properly?

I just got out of a philosophy class and I realized that I accidentally double booked tomorrow. Now I need to teach philosophy to a group of 8 and 9 year olds and I'm not sure how I should go about it.<br>The topic for this week is the mind-body problem. Is there a way to make this topic engaging for young children?<br><br>I think a good approach is to start with the idea of "ghosts in the machine," but I'm not sure where to continue with this. <br><br>I am open to any ideas, it can be anything from a game to an activity to just discussion.
