The Variety and Roles of Microbes
If they have not done so already, direct students to arrange their cards by “role in food production,” “role in causing disease,” and “role in the ecosystem/environment.”
Then, lead a discussion about the items in each of the three groups. Notice that some microbe cards may fit into more than one group. What similarities and differences do the students notice about the cards in each group? Are there any surprises? Make a particular note of the role microbes play in food production. This may surprise your students.
