Today in Science 10 we began investigating how other "things" besides energy flow through an ecosystem. To learn about biomagnification, we became a new organism---a grasshopper, a shrew, or a hawk, and simulated a food chain. The grasshoppers fed on the corn fields (pipe cleaner pieces), the shrews fed on the grasshoppers, and the hawks fed on the shrews. Unknowingly the white pipe cleaner pieces were sprayed with a pesticide. The pesticide moved through the food chain becoming concentrated in the top consumer. Here are some pictures of our Deadly Links Game.
