A few years ago I did a first aid lesson for a Young Womens Class. This could be done for activity day girls, anytime of year but the supplies are easiest to get around Halloween. Just purchase your eyeballs now and save for when you give the class. The posted pictures came from this blog: http://creatingandcruising.blogspot.com/2009/10/spooky-eyes.html

Nurse Nancy would be a fun book to have one of the girls read aloud along with your first aid lesson. (Stating ahead of time that you know the book is young for them but is a fun way to start the theme)
