In the beginning of the school year, I introduce food chains to the students by having everyone, including myself, recite I Know an Old Lady Who Swallowed a Fly. We all have a good time with that humorous poem. Now that the class is exploring tropical rainforests, our poems have become a little more serious and mysterious, like this one that I created in direct connection to one of the pages in our science textbook. Eek! Eek! The Ecosystem! The plants eat the sunshine/ and the water,/ The beetle dines on leaves/ beside her daughter,/ The furry spider eats both insects/ like she ought to,/ A boa swallows them in one gulp/ for nutrients and water,/ And as the chubby snake rests,/ a hawk awaits the slaughter.// Moral:/ A rainforest rule that helps species survive,/ it's better to pray to eat prey/ than to pray while being eaten alive. One thing I remind students is that humans are not in any other animal's food chain. We just have to be careful not to whet a shark's or lion's appetite.
