Teacher: Cheryl Massengale
Topic: Bacteria and Viruses
Grade: 10th
Subject: Biology
Stage 1- Desired Results
Established Goals:
CDL.7.B.6
Compare and contrast the structures and characteristics of viruses (lytic and lysogenic cycles) with non-living and living things.
CDL.7.B.7
Evaluate the medical and economic importance of viruses.
CDL.7.B.8 Compare and contrast life cycles of familiar organisms
 sexual reproduction
 asexual reproduction
 metamorphosis
 alternation of generations
CDL.7.B.9
Classify bacteria according to their characteristics and adaptations.
CDL.7.B.10
Evaluate the medical and economic importance of bacteria.
Understandings:
Essential Questions:
Students will understand that…..
1. How do microscopic organisms affect our lives?
2. How do viruses compare to organisms? What are the components of a

Bacteria and viruses are abundant, diverse and
typical virus?
successful
3. How do viruses replicate?

Bacteria are small, unicellular organisms needed to
4. How are viruses specific to particular host cells?
recycle detritus and produce certain items such as
5. How does the virus that causes AIDS reproduce?
sauerkraut, cheese, and antibiotics
6. How can the spread of AIDS be prevented

Some types of bacteria cause disease
7. What are the distinguishing characteristics of bacteria, in terms of

Viruses are tiny, noncellular structures that can
anatomic features, food getting and reproductive methods; metabolic
reproduce inside cells and cause disease
activities, and environmental responses?

Viruses go through a lytic or lysogenic life cell
inside host cells
Student will know….

Living organisms are composed of cellular units
(structures) that carry out functions required for
life.

Living organisms have a variety of observable
features that enable them to obtain food and
reproduce

Viruses are nonliving structures because they are
NOT made of cells, but they can reproduce inside
cells
Student will be able to…

Differentiate between the two kingdoms of bacteria.

Explain the structure, shape, and size of bacteria

Describe how bacteria obtain their energy, food, and how they reproduce.

Identify beneficial and harmful things bacteria do for humans.

Explain the structure, shapes, and size of viruses

Describe the lytic and lysogenic life cycles of viruses

Identify viral disease and their treatments
Stage 2- Assessment Evidence
Performance Tasks:

Build three dimensional models of bacteria and
viruses

Use bromothymol blue indicator to test for the
presence of carbon dioxide produced by bacteria in
certain foods

Construct a wanted poster on any disease-causing
bacteria or virus.

Other Evidence:

Quizzes

Tests

Lab reports

Scaffold learning

Class discussions

Cold call questioning
Patient Zero lab
Stage 3 - Learning Plan
Resources:


"Device uses sewage bacteria to produce electricity"
PowerPoints on Bacteria & Viruses
Summary:
This unit teaches students the distinguishing characteristics of bacteria, and
viruses in terms of anatomic features, food getting and reproductive methods;
metabolic activities, beneficial and harmful effects, and environmental
responses.
