Russellville High School - Understanding by Design Template
Teacher: Cheryl Massengale Topic: Bacteria and Viruses Grade: 10th Subject: Biology
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:
Students will understand that…..
· Bacteria and viruses are abundant, diverse and successful
· Bacteria are small, unicellular organisms needed to recycle detritus and produce certain items such as sauerkraut, cheese, and antibiotics
· Some types of bacteria cause disease
· Viruses are tiny, noncellular structures that can reproduce inside cells and cause disease
· Viruses go through a lytic or lysogenic life cell inside host cells / Essential Questions:
1. How do microscopic organisms affect our lives?
2. How do viruses compare to organisms? What are the components of a typical virus?
3. How do viruses replicate?
4. How are viruses specific to particular host cells?
5. How does the virus that causes AIDS reproduce?
6. How can the spread of AIDS be prevented
7. What are the distinguishing characteristics of bacteria, in terms of anatomic features, food getting and reproductive methods; metabolic activities, and environmental responses?
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.
· Patient Zero lab / Other Evidence:
· Quizzes
· Tests
· Lab reports
· Scaffold learning
· Class discussions
· Cold call questioning
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.
