Description
Today, we completed a lab that simulated how bacteria have evolved to resist modern antibiotics. We used two dice to represent the drug penicillin. And we started off with a group of 20 strep bacteria, each one with a strength rating from 1-10. Students rolled the dice for each bacterium, and if they rolled higher than the cell’s strength rating, they successfully killed off that bacterium. After rolling for all 20 cells, students copied over the survivors and had them reproduce, as if the germs had passed on to another person. Then they repeated the process, rolling the dice, killing off some of the cells, and passing the germs on to a new person. After five rounds, the result was clear; bacteria are getting stronger!
A copy of the lab can be found above. For more information, please click here.

NGSSMS-LS4-3
Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy. Emphasis is on inferring general patterns of relatedness among embryos of different organisms by comparing the macroscopic appearance of diagrams or pictures. Assessment of comparisons is limited to gross appearance of anatomical structures in embryological development.
NGSSMS-LS4-1
Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past. Emphasis is on finding patterns of changes in the level of complexity of anatomical structures in organisms and the chronological order of fossil appearance in the rock layers. Assessment does not include the names of individual species or geological eras in the fossil record.
NGSSMS-LS4-2
Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships. Emphasis is on explanations of the evolutionary relationships among organisms in terms of similarity or differences of the gross appearance of anatomical structures.
NGSSMS-LS4-5
Gather and synthesize information about technologies that have changed the way humans influence the inheritance of desired traits in organisms. Emphasis is on synthesizing information from reliable sources about the influence of humans on genetic outcomes in artificial selection (such as genetic modification, animal husbandry, gene therapy); and, on the impacts these technologies have on society as well as the technologies leading to these scientific discoveries.
NGSSMS-LS4-4
Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment. Emphasis is on using simple probability statements and proportional reasoning to construct explanations.
