This lesson teaches students a little bit about how biotic and abiotic factors interact to create an ecosystem. The lesson starts by teaching students these vocabulary words, and then having them becoming more familiar with them through practice. First, students have to decide whether specific factors are biotic or abiotic, and then they have to decide which factors might have an effect on another factor, and how.
Student understanding of abiotic factors, biotic factors, and their interactions are deepened through the examination of the case study of the Chesapeake Bay and the collapse of the oyster fishery. The lesson culminates with asking students to create a concept map using the abiotic and biotic factors that contributed to the decline of the oyster population in the Chesapeake Bay.
