Many people, children included, confuse the characteristics of bacteria and viruses. The lesson introduces students to each and helps identify the differences between each. When students hear the terms, they usually think of them negatively, but it is important for students to understand not all bacteria and viruses are harmful organisms. There are several animated videos as part of the additional resources, which would be helpful to the class. Lesson may be used in conjunction with an Asexual Reproduction lesson.
Sample Classroom Procedure / Teacher Instruction
