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
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)
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 –
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

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 –
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
_______
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.
