Summer SAVY 2018: Session 1, Day 3 – Biology and the Body (Rising 5th and 6th)
In today’s class of Biology and the body we finished learning about the innate versus the adaptive inmmune system. We also learned about immunodeficiency and autoimmune disorders and how they affect the individual and the immune system.
Then we explored the world of microbiology. We learned the four main types of microorganisms which are bacteria, fungi, viruses and parasites. We spend time discussing and learning about good and bad bacteria. We learned that bacteria are prokaryotes and that our cells are eukaryotes because they have a nucleus and membrane-bound organelles. We also learned that antibiotics are used to treat bacterial infections but too much antibiotics is not good for us or the good bacteria in our gut. We also learned the terminology antibiotic resistance in which bacteria can become resistant to antibiotics. We were introduced to tuberculosis and its symptoms. Tomorrow we will learn more about TB test and how to prevent TB.
To put the concept of germ transmission in practice we performed an activity with glitter. One person would have glitter in their hands and then shake hands with other students. At the end of the activity we looked at how many people had glitter in their hands. We culminated today’s lesson by applying the scientific method, making a question and hypothesis and then growing bacteria on petri dishes to test our question. We are all excited to observe our petri dishes tomorrow and discuss our results!
