Classroom Microbes

Activity Summary
Microbes are organisms that are too small to see with the naked eye. Large aggregations of microorganisms can be grown in a petri dish to observe without a microscope. Bacteria and fungi are both ubiquitous in most environments, including your classroom. In this laboratory exercise, you will hypothesize about the presence of these microbes and then sample your surroundings.
