[MOSAIC] Gross but fun reading

[James Rollin, Edward Wolfe]

As a teacher, I love to be able to engage my students as much as  
possible with off the wall topics and discussions.  One of my most fun  
topics are things like poop, and other gross things.

I am a proud owner of "The Truth About Poop" by Susan Goodman and  
would like to get some titles that are just as fascinating and fun and  
most important, gross!!!  These titles should fall into the  
non-fiction category please.  If anyone has any suggests on titles and  
some new ways to use them with grade 4-6 I would really appreciate it.
