Period 4 Science- 10/15

Today in class, we read about Louis Pasteur. In the 1800s people believed that organisms could spontaneosly arise without parent organims.He tested that hypothesis. He was not the first to test this hypothesis. In 1668, Italian physican Francesco Redi proved that maggots were found on meat because the meat was left out for a few days and attracted flys. The flys layed eggs on the meat and they formed into maggots. After we read, we took the online quiz on the topic.
Next, we discussed where bacteria grows. We came up with a lot of things, such as tables, water fountains, and other places, too.
