Level#1: In hospital rooms of the 1800s, many people died from infections that started in uncovered, or open, wounds. A Scottish doctor named Joseph Lister guessed that germs might be causing these infections. He look for and found a good "germ killer." It was carbolic acid. Lister began to cover open wounds with bandages soaked in weak carbolic acid. Lister also washed his instruments and hands with carbolic acid. He even tried spraying his operating room with carbolic acid.
1. What did many people die from in the 1800s that started in their uncovered, or open, wounds?
2. What did the Scottish doctor Joseph Lister do?
3. What did Scottish doctor Joseph Lister look for and find?
Level#2: In hospital rooms of the 1800s, many people died from infections that started in uncovered, or open, wounds. A Scottish doctor named Joseph Lister guessed that germs might be causing these infections. He look for and found a good "germ killer." It was carbolic acid. Lister began to cover open wounds with bandages soaked in weak carbolic acid. Lister also washed his instruments and hands with carbolic acid. He even tried spraying his operating room with carbolic acid. The results were great. The number of infections went down. Many patients stayed alive who would have died before. Lister's carbolic acid was the first antiseptic, or germ killer, that worked. Soon, doctors learned that steam could kill germs, too. Today, medical instruments and bandages are sterilized by putting them in hot steam. Doctors wear sterilized gloves, clothes, and masks.
1. What was killing many people in hospital rooms in the 1800s and what did Scottish doctor Joseph Lister think was causing it?
2. What did Scottish doctor Joseph Lister look for and find, and what did he do as a result of what he found?
3. How did Scottish doctor Joseph Lister's use of carbolic acid work out?

Today, medical instruments and bandages are sterilized by putting them in hot steam. Doctors wear sterilized gloves, clothes, and masks. Several years after Lister's discovery of antiseptics, two other scientist found out more about fighting disease. They were Louis Pasteur and Robert Koch. Together these scientist came up with the idea of the germ theory. The theory proposed that germs, or microscopic organisms, caused diseases. Their theory, led to many other advancements in understanding the causes of diseases.
1. Explain what Scottish doctor Joseph Lister "guessed" was causing infections that people were dying from, and what did he look for and find to try and fix this problem.
2. Explain what Joseph Lister did as a result of discovering carbolic acid.
3. Explain the resulting outcome of Joseph Lister's use of carbolic acid.
