Medical Interventions- Dr. Edward Jenner

During the 18th centry there was a huge occurance of small pox around the united states. 45 million people were victims of small pox. Dr. Edward Jenner noticed that the only people that were not getting this disease were cow maids, and that they had already contracted the disease cow pox. So he did a little research and some tests. He thought that the puss from a sore of the disease cow pox could possibly kill off the small pox resulting in curing the disease. So to test this theory, he injected a small healthy boy with the puss of the cow pox. He noticed that the boy had a small fever but somewhat recovered. After that he had taken the small pox virus and had injected it into the bloodstream of the boy. A few days later the boy appeared to be normal. This was a breakthrough in the medical community. This was when the term "vaccination" was created.

Medical Interventions- Cochlear Implant Debate

Over the past couple of weeks we have been doing a segment on hearing and how it can be lost. We have been assigned new partners as usual and have began to look at some of the hearing problems in the world as well as tools to help determine the problem. A tuning fork is a very important tool to have in an experiment determining if the person has trouble hearing or not. After that, we tested our own hearing and how well we heard. The next week we started researching about a cochlear implant, which is a device in which a person who cannot hear, can hear again. We were assigned to debate about it, being for or against, then having a debate in the classroom about some of the facts. I was against. We seemed to be very strong on our topic, but so was the other team. Overall it was fun, and I can't wait to see what we are doing next week.
