This week, we wrapped up our classification chapter and took our chapter test. We did a brief overview of the two bacterial domains (Archaea and Bacteria), and we talked about how bacteria reproduce, how important they are to our environment and our health, and a bit about pathogenic bacteria. Most of us also like to eat at least some products that are made from bacteria (cheese, yogurt, sour cream, sourdough bread, pickles, etc.). We watched a few BrainPOP videos about bacteria, antibiotic resistance, and our immune system on Thursday. Next week we will view bacteria under the microscope, calculate the growth rate of bacteria, and talk about pathogenic bacteria in more detail.
