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.
1. Identify mold and bacteria
2. Explain where these microorganisms are found
3. Analyze the results of their petri plates and associated hypotheses
