Benchmark 4. (Viruses)
In this benchmark lesson, students will learn about viruses. The lesson begins with a bell-ringer that has students write down what they think a virus is and whether or not it is living. Once the students complete their bell-ringers they will work with their shoulder-partners to arrange images of the viral lytic cycle and provide explanations for why they chose their placements. Then partners will share with those nearest them and as a class will construct a larger version of the lytic cycle. Next, the teacher will give students a quick, interactive lecture about viruses and the lytic and lysogenic cycles. During the lecture, students will write down notes as well as answers to questions posed throughout the lecture on the handouts that accompany the lecture. At the end of the lecture, the class will revisit their replication cycle arrangements and write down what changes need to be made and why, to be turned in as an exit ticket at the end of the day.
Students will be able to:
- Arrange the steps of the lytic cycle in the correct order
- Compare and contrast the lytic and lysogenic cycles
- Describe the parts of a virus
- List reasons why a virus is not considered living
