What This Standard Means
What Students Need to Do
- Students trace how government or business decisions change where people live and work, and what happens to land or water. They compare effects across places and judge how large the changes were using evidence.
What Mastery Looks Like
- A student can explain how Hoover Dam supplied water and power to growing cities while flooding land and changing river flow. They can use maps and population data to explain why its effects differed upstream, downstream, and in nearby cities.
Common Misconceptions
- Students may credit the dam for all nearby city growth, ignoring other causes. They may describe benefits for cities but miss flooded land and changes to the river downstream.
How to Assess It
- Show a map of the Colorado River before and after Hoover Dam and a chart of Las Vegas population growth. Ask: What changed for people and the river, and how much of that change can you link to the dam?
Lesson moves
Ways to Teach It
Give pairs river maps from before and after Hoover Dam; have them shade flooded land and mark where Las Vegas gets its water.
Ask: Did Hoover Dam help nearby cities enough to outweigh changes to the river? Support your answer with a map and population chart.
Run a card sort with new irrigation, flooded habitat, and relocated residents; students label each human, physical, or both, then rank the effects.
Show a proposed shopping center plan; students use a street map to predict changes to jobs, traffic, and runoff.
