Did you know there’s wars going on in your body every day? Well thanks to your immune system, they keep pathogens at bay. It rhymes! Read more to learn about the immune system, what each of them do, and about pathogens!
Before we start swabbing the school, we need to do research first. Then a plan! I was going to need 2 Petri dishes and 2 cotton swabs. After all my research was done, everyone got to swabbing. My plan? Go to the bathroom and swab the sink. One on each Petri dish 🧫. I would leave one in a warm place, and one in the fridge. It was obvious which would have more bacteria, but I was surprise after the weekend.
The cold one has almost 0 bacteria! All I saw were a few specks but compared to the warm one, it was so clean! The warm one has weird orange and yellow specks, along with white splotches all over! Ew!
Enough of that, let’s get into the immune system! We made characters cards to help tell what each cell does! I decided on the theme Candy, because I thought it would be super cute! There are 5 main cells in the immune system; the macrophage, the white blood cell, the antibodies, the B-cells, and the t-cells.
Come on, you can’t tell me that’s so cute!
Last thing was vaccines. We watched a really interesting documentary on Polio and the first vaccine called “The Polio Crusade”. It showed how everyone’s lived were change with polio. The first vaccine was made when Dr Edward Jenner noticed that milkmaids who had contracted cowpox wouldn’t catch smallpox. He guessed that being exposed to cowpox would make you immune to smallpox. He took a sore from a cow with cowpox and rubbed it on a wound of a little boy who had smallpox. After a few days of sickness, the boy went on to make a full recovery. I find this super interesting, that cowpox is like smallpox.
