Identify bodies of water such as rivers, lakes, and oceans near their region, and explain how communities use water and other natural resources.
Every community depends on water. Rain and melted mountain snow fill rivers and lakes, which then get stored behind dams in reservoirs, or pumped through pipes and canals called aqueducts, so it reaches homes, farms, and businesses that might be far away.
A natural resource is anything from nature that people use: water, rich farming soil, forests for wood, and minerals in the ground. California's biggest natural resource is its water system -- melted Sierra Nevada snow, stored in reservoirs, travels hundreds of miles through aqueducts to reach cities and farms that would otherwise be too dry to support so many people.
Mastery looks like: They can name a body of water near their region and explain, in general terms, how water travels from a natural source to their own home.
Common stumbles: Assuming tap water simply appears at the faucet, without any real source, storage, or travel involved.
