What This Standard Means
What Students Need to Do
- Students compare places where population grew or shrank. They use dated counts, maps, and images to explain changes to land, housing, and services. They judge the benefits and costs of those changes.
What Mastery Looks Like
- A student can use population counts and aerial images to show how Phoenix expanded onto desert land and added roads. They can show how Detroit lost residents and developed vacant blocks. They explain a cost of each change without claiming population was the only cause.
Common Misconceptions
- Students may treat empty houses as a change to the natural environment rather than the built environment. They may assume a shrinking city automatically gains green space, or that population change alone caused every closure or new road.
How to Assess It
- Give students population counts and paired aerial images for Phoenix and Detroit. Ask them to name one land change and one housing or service change in each city, then judge one benefit or cost.

Ways to Teach It
Give students Phoenix and Detroit aerial images from 2000 and 2020; have them trace new pavement and empty lots on clear overlays.
Ask: How did growth in Phoenix and decline in Detroit change land and city services, and who gained or lost?
Sort cards labeled desert habitat loss, new roads, empty houses, and school closures by city, then mark each as a land or built-environment change.
Use local census counts from 2000 and 2020 with dated street photos; explain whether a new subdivision or closed school fits the population trend.
