With articles entitled, "What's Puke?" and "What is a Fart?" this digestive system lesson plan is sure to be a gas! Elementary anatomists do a belly dance to illustrate how food moves through the digestive system and then design a board game in which the board is shaped like the organs involved. Several articles and a video are available through the publisher's website to provide information. Note that because the website has been updated since the production of this document, not all of the article and video titles are the same. Don't eliminate it, however! Laughter and learning are sure to be expelled during this session!
