C3 Framework · Grades 9–12
Analyze the reciprocal nature of how historical events and the spatial diffusion of ideas, technologies, and cultural practices have influenced migration patterns and the distribution of human population.
Why water teaches this standard well
Drought and water access have repeatedly moved people, from the Dust Bowl migration to present-day relocation away from water-stressed regions. Students can analyze how the spread of water technologies such as center-pivot irrigation and long-distance aqueducts redistributed population across arid lands, and how that growth now strains the water that made it possible.
