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
