Reflection: Real World Applications Antibiotic Lab Investigation (Day 3 of 3) - Section 5: Lesson Extension & Follow-Up Activities


This first full-length lab investigation centered on the interplay between antibiotics and bacteria. There were several "storylines" I wanted to develop. First of all, from a healthcare perspective, simple precautions and knowledge can help turn the tide toward humans in the battle with microbes. Simply washing hands frequently and proper use of antibiotics are first steps to staying healthy and not unwittingly contributing to resistance. From a natural selection  perspective, students were able to see that not all antibiotics were equally effective at killing the target bacterial cells. See the graphs from lab report #1 and #2 and notice the variable "death zones". Students recognized that factors in the environment (e.g. antibiotics) can change the course of bacterial adaptation and that this derived resistance can easily spread among bacterial populations.

The other major storyline is how, through inquiry, the scientific method applies to many of the Science Practices (i.e. crafting relevant questions, planning and carrying out investigations as well as analyzing data and using it to draw logical conclusions). It is all in there!

It is evident that neither reports are perfect but they represent strong steps toward implementing all phases of the inquiry process. We will continue to refine our abilities to implement the science practices in successive investigations throughout the year.

Antibiotic Lab Investigation (Day 3 of 3)

Unit 1: 1) Intro to Science ("Investigations by Design")
Lesson 10 of 10

Objective: Students will learn the basic details regarding the background history of antibiotics, the nature of bacterial organisms, and explore the phenomenon of antibacterial/antimicrobial resistance in a hands-on manner.

Big Idea: Bacterial infections, the use of antibiotics, and their increasing resistance to many antibiotics is a growing and widespread issue for medical science. Students will investigate this issue in a hands-on lab.
