Activity Description of "Food Webs and Trophic Levels"


Title Food Webs and Trophic Levels
Audience H.S. Biology, regular and basic leve & ecologyls
Abstract In an effort to create a more student-centered curriculum, I have designed a quick, one-day activity to teach students in an ecology unit about the feeding interactions of organisms and how this related to their trophic levels. Ths activity allows students to work in cooperative groups, where each group contributes to a class food web displayed in the front of the room on a presentation board. Each group is also responsible for assigning the different trophic levels to the food web. Activity ends with a discussion and analysis of the food web and feeding levels, where students are assessed on their understanding of the terminology and concepts. The lesson works well for students in both regular and basic level biology classes, as well as any ecology class.
