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.

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)

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
Living Conditions in 1840’s London:

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.
