(4) Science concepts. The student knows that cells are the basic
structures of all living things and have specialized parts that
perform specific functions, and that viruses are different from
cells and have different properties and functions. The student is
(C) Compare the structures and functions of viruses to cells
and describe the role of viruses in causing diseases and conditions
such as acquired immune deficiency syndrome, common colds, smallpox,
influenza, and warts
(11) Science concepts. The student knows that organisms maintain
homeostasis. The student is expected to:
(D) Summarize the role of microorganisms in maintaining and
disrupting equilibrium including diseases in plants and animals and
decay in an ecosystem.

Describe the structure and shape of viruses.
Distinguish the differences between lytic and lysogenic cycles.
Explain the mechanism of transduction.
Identify and describe several viral diseases and ways to defend

presentation and take down informative notes throughout the lesson.
They should be able to fulfill all of the objectives at the end of
the lesson and answer at least 70% of the questions correctly on the

most of the questions, then I will go over the material
again more slowly and more in depth.)
I will give
them a question to answer on their own on a separate piece
of paper. Then I will ask the students to discuss their
answers in groups and then have several students share their
responses to the class.
