Letters I Never Thought I Would Have to Write

Dear Parents,

Of late, I have noticed the students talking about flatulence but in their colloquial terms of “farting” and “puffing”.  I am not sure what has spurred this conversation topic on, however I would like to take the wind out of their sails a bit and help the students understand the process of flatulence. I’ll be using a science resource called, Grossology, which gives a very clear explanation. 

If you hear your child talking about this topic, I encourage you to ask them to explain the process to you.

Thank you for your time,

So here is the diagram I created to teach this unit. I decided to use a cow (rendering is more deer/dog-like) as they are actually greater producers of toxic gases than us lowly humans (We average only 14 toots a day). Each piece of the digestive system can be blue-tacked on.  (And before I get inundated with emails... yes, I know cows have four stomachs).
It is my hope that in divulging the process of flatulence, the students will see it as a common bodily function and quite obsessing on it. However I realize that my plan could 'back-fire' and then I would have a real mess.  Oh, the risks one takes in the field of education!
