Warmup: What do you know about bacteria? What do you want to learn?
(23) Germ Theory Notes - Focus Question - What is germ theory? What are bacteria?
Students took notes about how in the past diseases were very misunderstood until a couple of scientists - Robert Kock and Louis Pasteur conducted a series of experiments and investigations to show that living things and diseases don't "spontaneously generate" (appear out of nowhere) they must be causes by living, microscopic organisms. This revolutionized our understanding of health and diseases, and led to the creation of vaccines and antibiotics.
Bacteria are often called "germs" and they are sometimes given a bad rap. Bacteria are simple single celled organisms that live just about everywhere on the planet, and even inside of us. They are extremely small, and while some are harmful, most are pretty harmless or even helpful (what do you think makes cheese and yogurt?.... Bacteria!)
(22) Bacteria Lab - Students then created a foldable to organize an experiment they are conducting comparing 2 sources of bacteria. They then used agar plates and cotton swabs to take samples from their subjects and then incubated their petri dishes.
We will record the results for the whole week.
