Introduction

Students will have time in class to make observations on their bacterial cultures.

The rest of the period will be devoted to a debate on whether or not people should try to kill off all different types of bacteria.

Name: Becky Lederman, Sue Bros, Ken Bateman	Bacteria and Viruses Unit
Class: Biology Day 9

Topic: Continuation of Bacterial Culture Lab, Debate

Reference to MA Science Framework and/or NSES:

2.1 Relate cell parts/organelles to their function

2.2 Differentiate between prokaryotes and eukaryotes

Global and Curricular objectives for students:

SWBAT collect data from their lab experiment

SWBAT make statements and defend their point of view in a class debate.

Brief description of lesson (include start, middle, and end)

1. Students will be given the first part of the class to make observations on their bacterial cultures from the week before. They will record their observations in their lab notebooks.

2. Students will be given the second part of the class to debate whether bacteria are good or bad.

Teacher will provide products that relate to the topic (i.e. instant hand sanitizers, antibacterial soaps and cleaning products, empty antibiotic prescription bottles, yogurt, live cultures, etc.)
Teacher will introduce discussion by asking if we should try to kill all different types of bacteria. Further questions to keep students on track can include the following:

1) Do antibiotics only target the type of bacteria that is making you sick?

2) What happens when a bacterium becomes resistant to an antibacterial agent?

3) What would happen if there were no more bacteria on Earth?

4) What are some ways that bacteria help society? (Review question)

Homework

Lesson evaluation (Identify successful management, learning, enjoyment and the evidence of it. Refer to objectives. Areas for development.)

Student assessment (Knowledge, skills, and understanding)

Continue work on researching bacteria.

Successful management and learning will be evident if students are participating in discussions and supporting their arguments will information gained in class.

Formative assessment can be used throughout the debate as students will need to use supporting evidence for the comments/arguments they present.

Adjustments for special needs students: None

Materials, equipment and supplies: Lab materials from previous week.

Safety concerns: Goggles and rubber gloves when handling culture samples. Students must wash hands using hand washing technique learned in week one.
