What is the process called when milk is heated to a temperature of 50 or 60 degrees centigrade to make germs harmless?
Pasteurization
What branch of science did Louis Pasteur found?
Bacteriology
What did Louis Pasteur believe was the cause of most infectious diseases?
Bacteria
Who had already discovered vaccination for smallpox before Pasteur's time?
Dr. Jenner
What did Louis Pasteur spend three years tracking down the cause of, which had ruined the silkworm industry?
Disease
What did Louis Pasteur experiment with in his laboratories to help his fellow human beings?
Research
What was the purpose of Pasteur's experiment with bottles of soup in different locations?
To show the difference between pure and stale air.
What was the result of the bottles opened in the hotel bedroom in Pasteur's experiment?
The soup had gone completely mouldy.
Why did Pasteur open some bottles of soup on a high mountain in his experiment?
To see if the bottles would contain germs.
What did Pasteur's experiment with the bottles of soup demonstrate about the importance of pure air?
Pure air is essential to prevent the growth of harmful germs.
What term is used to describe the process discovered by Pasteur to prevent wine from souring?
Pasteurization
How did Pasteur's experiments contribute to the understanding of spontaneous generation?
They disproved the theory of spontaneous generation by showing the role of germs in contamination.
What was one of the main problems Louis Pasteur was trying to answer?
Do germs form from other germs, or do they just come of themselves?
Explain the concept of 'spontaneous generation' and how it related to the belief about germs at that time.
Spontaneous generation was the belief that germs had no parents but just occurred by themselves. Some people believed in this idea, thinking germs could arise spontaneously.
Describe Louis Pasteur's experiment to prove his theory about the origin of germs.
Pasteur put soup in bottles, boiled them to destroy any germs, then bent the necks of the bottles. The soup remained uncontaminated because no parent germs could reach it.
What was the significance of the bend in the bottle neck in Pasteur's experiment?
The bend acted as a 'dust trap' preventing germs from reaching the soup, thereby keeping it uncontaminated.
How did Pasteur show that germs from the air could contaminate the soup in his experiment?
Pasteur spilt a little soup down the tube to the bend, where it went bad. This demonstrated that dust, carrying germs, could infect the soup beyond the 'dust trap.'
What was the role of dust in Pasteur's experiment and how did it relate to the contamination of the soup?
Dust carried germs with it and settled in the bend of the bottle neck, infecting the soup beyond the 'dust trap.'
