What This Standard Means
What Students Need to Do
- Students use old maps and photos alongside later accounts to find changes people made to land and water. They explain how those changes affected travel, communities, and the environment, using details from the sources.
What Mastery Looks Like
- A student can use an Erie Canal map to show where people dug a new waterway. They can use a historian's account to explain how it sped up shipping and changed nearby waterways.
Common Misconceptions
- Students may call a later textbook account a primary source because it describes an old event. They may name a benefit, such as faster travel, but overlook changed waterways or effects on people already living there.
How to Assess It
- Show an Erie Canal map and give students this summary: “The canal shortened shipping routes but changed streams and wetlands.” Ask them to name the physical change, cite one map detail, and give one benefit and one cost.

Ways to Teach It
Dig a canal through damp sand in a tray, pour water through it, and mark where the new channel cuts across land.
Show an Erie Canal map and a historian's paragraph; ask, “How did the canal help traders, and what land or water changed?”
Give pairs canal maps, dam photos, and historian blurbs; have them match each change to one benefit and one environmental cost.
Trace a highway on a town map, then mark where pavement may increase runoff and where it makes travel faster.
