  1. GK-12 Saturday Workshop February 6, 2010 CT: Gwen Blankenship RS: Amy Zimmerman

  2. Outline • “Small Things Considered” • Bacterial numbers game • “Soap vs. Sanitizer” • Laboratory experiment

  3. Small Things Considered

  4. Activity Objectives • Gain an appreciation for the ubiquity of microbes • Understand that only a small percentage of bacteria are harmful

  5. Standards Covered • 7th Grade: Life Science • 1. All living organisms are composed of cells, from just one to many trillions whose details usually are visible only through a microscope. • 9-12th Grade: Biology • 10.d. Students know there are important differences between bacteria and viruses with respect to their requirements for growth and replication, the body’s primary defenses against bacterial and viral infections, and effective treatments of these infections.

  6. Prior Knowledge • Bacterial replication • Species classification • Vocabulary: • Pathogenic

  7. Activity • Work in groups of 2-4 • Cards • Green: Bacterial Abundance • Pink: Bacterial Distribution • Goal • Match the correct number with the definition card

  9. Answers

  10. Post-Assessment • Class discussion • What was most surprising? • How do you feel about bacteria now?

  11. Soap vs. Sanitizer

  12. Activity Objectives • Practice good experimental design • Create, analyze, and interpret data • Learn basic microbiology techniques • Increase awareness about hand hygiene

  13. Standards Covered • 7th Grade: Life Science • 1.a. Students know cells function similarly in all living organisms. • 2.a. Students know the differences between the life cycles and reproduction methods of sexual and asexual organisms. • 7.a. Select and use appropriate tools and technology to perform tests, collect data, and display results. • 7.c. Communicate the logical connection among hypotheses, science concepts, tests conducted, data collected, and conclusions drawn from the scientific evidence.
