C3 Framework · Grades 9–12
Evaluate how changes in the environmental and cultural characteristics of a place or region influence spatial patterns of trade and land use.
Why water teaches this standard well
Aquifer depletion and drought are already shifting which regions grow water-intensive crops, and trade in those crops moves water virtually from dry exporting regions to distant consumers. Students can evaluate how changing water conditions in one region rearrange patterns of agriculture, land use, and trade elsewhere.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
Grade 11 Lesson plan
Students trace eighty years of a fictional High Plains county's irrigated acres, population, and water levels, then explain how pump technology reshaped who lived there.
Grade 10 Worksheet
A grade 10 worksheet using a fictional county's twenty-year crop table to analyze how a shift from hay to orchards moved water into distant trade.
Grade 10 Worksheet
A grade 10 worksheet using five years of snowpack and runoff data from a fictional basin to test a reservoir's flood rule against a drought shortfall.
Grade 12 Worksheet
A grade 12 worksheet on a fictional city's proposal to lease irrigation water from a farm valley, with acre-foot math and analysis of third-party effects.
Grade 9 Worksheet
A grade 9 geography worksheet where students calculate the virtual water in a fictional county's beef and wheat shipments and reason about drought, trade, and land use.
Grade 11 Reading passage
A grade 11 geography passage tracing how multi-year drought moves through farming, hydropower, and city budgets until dry years become a region's planning assumption.
