Lesson Five: Bacteria Treatment; Antibiotics
Hook: Antibiotic Resistance Is A Growing Threat
Students watch a video on the growing concern among health experts worldwide on resistance to antibiotics. YouTube Video: http://www.youtube.com/watch?v=QKaTlqOQTnw Activity:
1. What are antibiotics?: Teacher-centered learning in which the instructor goes through an “Antibiotics Attack” webpage that examines what are antibiotics, pathways of attack, penicillin, and antibiotic resistance. Antibiotics Attack Webpage: http://www.hhmi.org/biointeractive/Antibiotics_Attack/frameset.html |
ANTIBIOTIC RESISTANCE |
2. Bacterial Resistance to Antibiotics: Students read, individually or in pairs, section 2.12 “Bacterial Resistance to Antibiotics” pg. 126-127 and answer the related questions to explore how many disease-causing bacteria have slowly developed resistance to antibiotics.

3. Take A Stand: Bacterial Resistance to Antibiotics: Students watch a video on the story behind antibiotics and livestock. In arranged groups of 3, students explore an issue of whether non-therapeutic use of antibiotics in farm animals should be banned, taking into consideration health, societal, economic, personal, and etc. Students must complete the worksheet to state and justify their decision.

Consolidation/Debrief: Bacterial Resistance to Antibiotics - Four Corners
A group activity in which students cooperate together to go to a corner (the four corners are labeled by the instructor with the options of – strongly agree, agree, disagree, strongly disagree) to indicate how they feel towards whether non-therapeutic use of antibiotics in farm animals should be banned. Students gather in the corner of the room that corresponds to their choice and discuss the reasons for selecting their particular choice. Students then voluntarily share their reasons, in which the instructor also facilitates a discussion on antibiotics and bacterial resistance to debrief the lesson.
