Eileen's Food Chain Talk


Heatherwood garden

In an effort to integrate the Heatherwood Garden into the school curriculum, Ms. Jenkins and her second grade class hosted me for a garden lecture. The class just visited NCAR for a science unit about weather. Ms. Jenkins wanted to connect the weather series to a garden presentation. So, we talked about food chains and food webs. I read the class the book Who Eats What by Patricia Lauber. We talked about how weather is directly linked to how crops like wheat and corn grow and how these foods support a complex food chain that includes them and the foods we eat.

To illustrate the links and dependencies on a food chain, I had the kids draw pictures of their favorite foods on paper plates and then we made paper chains to represent the food chain of their favorite meals. A few class favorites were definitely hamburgers and steak. So, we created paper chains that showed how the sun helps wheat grow, which cows eat. We, in turn, use the cows for steak and hamburgers, and we eat the meat. Many of their chains showed: Sun - Wheat - Cow - Me! A few of the children were surprised to learn that the pepperoni on their pizzas was actually from pigs! We ended the craft with some homemade, seasonal pumpkin bread!
