This was a story from my good friend who’s a fifth grade teacher here in Oregon. Here is the email:
I was teaching the 5th graders about the systems of the human body. Our focus was the digestive system. I asked the kids to explain the beginning of the digestion process. One student raised her hand and explained that she believed the brain was the beginning because the brain is in charge of our senses.
She said that when you see and/or smell food, your mouth waters.
I said, "That is exactly right. The extra saliva in your mouth aids in mastication. Who can tell me what mastication is?"
A very bright fifth grade boy raised his hand and excitedly said, "I know what masturbation is, Mrs. Jones!!"
There was a bit of puzzled silence and he raised his hand again and said, "But I don't know what that has to do with the digestive system."
