The black death – bubonic plague – spread by a bacteria living in fleas, that lived on rats, that followed trade routes.

Our history books focus on deaths in Europe.

Learning Standards

Massachusetts Science and Technology/Engineering Curriculum Framework

7.MS-ESS3-4. Construct an argument supported by evidence that human activities and
technologies can mitigate the impact of increases in human population and per capita
consumption of natural resources on the environment.
Clarification Statements:
• Arguments should be based on examining historical data such as population
graphs, natural resource distribution maps, and water quality studies over time.

7.MS-LS2-1. Analyze and interpret data to provide evidence for the effects of periods of
abundant and scarce resources on the growth of organisms and the size of populations
in an ecosystem.

7.MS-LS2-4. Analyze data to provide evidence that disruptions (natural or human-made) to any physical or biological component of an ecosystem can lead to shifts in all its
populations.

HS-LS2-2. Use mathematical representations to support explanations that biotic and abiotic factors affect biodiversity, including genetic diversity within a population and species diversity within an ecosystem

Massachusetts History and Social Science Curriculum Framework

Grade 6: HISTORY AND GEOGRAPHY  Interpret geographic information from a graph or chart and construct a graph or chart that conveys geographic information (e.g., about rainfall, temperature, or population size data)

WHII.36 Explain the various factors that contributed to post-World War II economic and
population growth

WHI.7 Describe the major economic, social, and political developments that took place in
