1. What did people think caused disease 1750 -1900 Discuss & write down a sentence to explain all images.

2. LO: How did scientists discover that germs cause disease. All will be able to…identify what people thought caused disease prior to Pasteur. Most will be able to…describe the work of Louis Pasteur and germ theory. (D) Some will be able to…explain factors that were important in the discovery of germ theory. (A)

3. Spontaneous Generation… Spontaneous Generation - Disease was caused by germs that were produced by flesh and vegetables as they rotted.

He called them animalcules and published his findings. What were these animalcules…? Draw a small image of the microscope and explain it…

5. Louis Pasteur WHO WAS HE? Born in France 1822. He studied chemistry and biology, taking charge of science at Lille University in 1854. It was his reputation as a top chemist that first led one of Lille’s top wine producers to go to Pasteur for help… WHAT DID HE DO? You each have a part of the story of Louis Pasteur… You have 12 minutes to piece together the story of Pasteur and complete your storyboard. You must educate rather than copy …
