What This Standard Means
What Students Need to Do
- Students use maps and photos to connect farming choices to changes in land and water. They explain how river diversion, rice terraces, and irrigation leave different marks on a region.
What Mastery Looks Like
- A student can explain how diverting rivers to cotton fields shrank the Aral Sea and exposed its salty seabed. They can identify rice terraces on a hillside and irrigation circles in a dry region.
Common Misconceptions
- Students may think the Aral Sea shrank only because of drought. They may mistake rice terraces for natural steps or assume irrigation cannot affect water supplies beyond a farm.
How to Assess It
- Show a before-and-after map of the Aral Sea with a note that rivers were diverted to cotton fields. Ask: 'What happened to the shoreline, and why?'

Ways to Teach It
Shape a hillside from modeling clay, press flat rice terraces into it, and pour a spoonful of water over both slopes.
Show two maps of the Aral Sea and ask students to write how cotton farming changed the shoreline and nearby land.
Give pairs photos of rice terraces, irrigation circles, and the Aral Sea; have them match each image to a land change.
Open Google Maps satellite view of a nearby farm; have students circle field boundaries and describe how the land differs from its surroundings.
