- Understand how natural selection leads to the predominance of certain traits in a bacterial population
- Correlate misuse of antibiotics with an increased probability of creating antibiotic-resistant bacteria
- Apply a model using probability to simulate how bacteria populations change in response to selective pressure
If your doctor prescribes antibiotics, why do you have to take them for several days and not just once? Why do you need to finish taking them even if you feel better? If you do not follow the doctor's orders, you might contribute to the creation of antibiotic-resistant "superbugs"! In this lesson, your students will roll dice to model how bacteria respond to treatment by antibiotics, and find out what happens if treatment is stopped too early.
