2 John Snow began to test two theories. 1 An outbreak of cholera hit London in 1854. 4 John Snow marked the deaths on a map. 7 He announced that the water carried the disease. 3 John Snow investigated two streets where the outbreak was very severe. 8 King Cholera was defeated. 5 He found that most of the deaths were near a water pump. 6 He had the handle removed from the water pump. Step III. Main idea and correct stage Read the passage and put the correct stages into the reading about research into a disease. John Snow Defeats “King Cholera”

Paragraph Stages

Step IV Group discussion Answer the questions (Finish exercise 2 on Page 3)

1. John Snow believed Idea 2 was right. How did he finally prove it? (John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.) 2. Do you think John Snow would have solved this problem without the map? (No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.) 3. Cholera is a 19th century disease. What disease do you think is similar to cholera today? (Two diseases, which are similar today, are SARS and AIDS because they are both serious, have an unknown cause and need public health care to solve them.) Step V. Using the stages for scientific research and write a summary.
