Mrs. Parks, the friendly science teacher, chose to teach her sixth-grade class a peculiar but instructive lesson in a tiny, well-lit classroom.
“Class, can anyone tell me which human body part increases to ten times its size when stimulated?” she leaned forward while asking with a twinkle in her eye.
The young people’s confusion caused a quiet to fall over the gathering. This was a very unusual question for a science class, and the students exchanged perplexed looks as they debated their best course of action.
