1010 Pasteur History of Medicine, pasteur, germ theory

TRANSCRIPT

Page 2: 1010 Pasteur

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)

Page 3: 1010 Pasteur

Spontaneous Generation…• Spontaneous Generation - Disease was caused

by germs that were produced by flesh and vegetables as they rotted.

People believed that germs were the result of disease, not the cause of it!

• Miasma – Disease was caused by bad air that was filled with poisonous fumes from rotting matter.

Van Leeuwenhoek• In 1677 – A clock maker from Holland,

Anthony van Leeuwenhoek, made a very basic microscope. To his amazement, he found tiny creatures moving about in nearly all of the things he placed under his new intervention. Found them in water droplets, pepper, food and faeces. He called them animalcules and published his findings.

What were these

animalcules…?

Draw a small image of the microscope and explain

it…

Louis PasteurWHO 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 …

Page 6: 1010 Pasteur

Pasteur…Once you have completed your storyboard…

- Summarise what germ theory is in your own words. - EXT: What factors were involved in Pasteur's

discovery?

Think! What factors have we looked at else where in the course (Jenner, how many times was the experiment repeated…)

Think! What role does ‘industry’ play (i.e. the silk company)?

Factors…

All Write Consensus…• You now have 6 minutes to discuss an answer to the

following question in your groups of four. After the 6 minutes you will write the same answer that you have discussed to the question in your own style.

• What factors affected Pasteur’s development of the germ theory? (12 marks).

Link the factors to how they helped develop Pasteur's work. You can’t write about them all, choose a

couple to focus on.

Group One – Lenny, Tom B, Alice, Amarilda.Group Two – Chelsea, Ellie, Liam W, Branden.Group Three – Max, Rebecca, Alice, Kira.Group Four – Connor, Joe, Shannon, Johnny.Group Five - Georgia, Asiatu, Tom H, Sophie.

Peer Assess

- Answer makes general comments on the germ theory. 1-4- Answer describes one factor such as the role of technology leading to improvements in the microscope. 5-8- Answer includes some explanation of various factors such as scientific methods and clearly explains how these helped in the development of the germ theory. 9-12
