  1. C32 Mapping Death DO NOW FOR 2/1/13 Take out your map and open books to page C-12. HW: None

  2. C32 Mapping Death • Today’s Target: I will be able to use the data about cholera deaths to make a hypothesis about how it is spread. • Check HW • Discuss data • Readings about Cholera • Analysis

  3. Recall O’ Shaughnessy’s description of Cholera’s symptoms • Symptoms of cholera • Diarrhea - Fingers bent • Periodic vomiting • Painful cramps • Severe dehydration • Sunken eyes • Black eyelids • Cyanosis (Body turns blue)

  4. C32 Mapping Death • What are ways different diseases can be spread? • Cargalon Fever (7th grade) – • Influenza (the Flu) – • Mononucleosis (Mono) – • Salmonella (Food poisoning) – • Malaria – • The common cold –

  5. C32 Mapping Death • State of science: • Germ theory – The idea that bacteria and other microscopic organisms cause illness and disease. • NOT ACCEPTED YET! • The prevailing theory about the spread of Cholera at the time: • Miasma – Bad air, smell • Living Conditions in 1840’s London:

  6. C32 Mapping Death – John Snow • Complete Analysis #4 on the back of your map. • Share your answer with someone around you. If they have a good answer add it to yours. • Based on the evidence from the mapping of death, our Hypotheses for spreading of cholera are –

  7. C32 Mapping Death – Key Points • 1. Scientists formulate and test their explanations of natural phenomena using observation, experiments, and physical and mathematical models. • Ex: Snow’s observations led him to believe that Cholera was not spread by miasma (bad air.) • 2. Scientists use appropriate tools and techniques to gather, analyze, and interpret data. • Ex: Snow plotted the deaths of people on _______. This allowed him to see __________ • 3. Thinking critically about evidence includes deciding which evidence should be used. • Ex: Snow focused on where people lived as opposed to _______

  8. C32 Mapping Death - Vocabulary • 1. Evidence: Observations or data to support a statement, hypothesis, or point of view. • 2. Hypothesis: A tentative theory used to explain a set of facts. A hypothesis can lead to further investigation to test whether the hypothesis is valid.

  9. C32 Mapping Death • Exit Ticket: • What additional data would John Snow need to prove his hypothesis?

  10. Open Books to page C-15 • HW: Complete analysis questions 1 and 2

  11. C33: John Snow and the Search for Evidence • Today’s Target: I will be able to research evidence to support John Snow’s hypothesis. • Exit Ticket Answers • Read Snow’s Theory on Pages C-15 • The Cholera epidemic Video – Intro. By Steve Johnson http://www.youtube.com/watch?v=3P8shnNEXb4 • Read pages C-16 through C-19. • Complete the table on student sheet 33.1 • Answer analysis questions 1 and 2 on page C-20

  12. Satellite Image of London
