Today, we went on the Spontanious Generation link under the Epidemics Unit link. We read the intro and conclusion. We also did the animation and quiz. You should read the actual article/link for more detail, bur here's a summary:

Louis Pasteur was a scientist from the 1800's. At that time and before his time, people believed in a "theory" called spontanious generation, in which life, such as maggots and microbes, could be born from a non-living thing, without a parent. Mr. Pasteur tested this idea. After he tested it, his data disproved this "theory", and made a new understanding in these organisms.

Then, we finished taking the notes on the HIV group from the three stories.

Some Notes:

• HIV stands for Human Immunodeficiency Virus
• Aids stands for Acuired Immune Deficiency Syndrome.
• There is no cure
• Spreads through bodily fluids
• First HIV blood test during 1985
• It breaks down immune system
• Can't die of AIDS, but from other diseases do it because there is no immune system
• No symptoms

Importance: The Spontanious Generation link is important because it it shows that life is not created like magic with no reason. It also shows how pasturization was invented. The link also shows you a visual of what the scientist did in his experiment.

Here's a video on Youtube that has to do with Louis Pasteur's experiment: http://www.youtube.com/watch?v=8eRAsztKfuI
