This isnāt high school level biology. I teach grades 4-9 science (including high school biology). I actually taught this very concept to my 4th grade class this morning. Theyāre a very smart group, so I went there with it. I normally teach that in 5th grade, and 99% of them understand it pretty well. I start it with āif you dye your hair blonde, your kids wonāt have blond hair because of it. If you get a nose-job, your kids wonāt be born with that nose.ā Then I progress to āif you do steroids and get as big as the Hulk, your kids wonāt be mini-Hulksā and āif you start training for marathons, your kids wonāt be born long distance runners.ā
They get it.
