I think its awesome! The kids learn about breaking words down into their parts, they learn to not be afraid of big words, and they also learn to be literate in biological sciences. As a nurse I find my job is much easier if the patient that I'm trying to talk to/teach is somewhat familiar with the human body and its parts. These kids don't have to file away and remember each of these particular terms now but down the line it will put them in a position of being able to have more information at a time when it may well be critical.
