This lesson plan is for a 45-minute science class on Wednesday, April 30th, 2014. The lesson will cover the five types of microorganisms (bacteria, fungi, protozoa, virus, algae), examples of each, and their effects on living things. Students will learn through a presentation, video examples, and individual/group exercises to define the microorganism types and explain their impacts. The teacher will evaluate students' understanding by having them define and list examples of microorganisms, and match microbes to their effects.
