Episode 1: Watersheds, Runoff & Pollution
DISCIPLINARY CORE IDEAS
ESS2.C: Roles of Water in Earth's Surface Processes
2-ESS2.C: Water is found in the ocean, rivers, lakes, and ponds. Water exists as solid ice and in liquid form.
5-ESS2.C: Nearly all of Earth's available water is in the ocean. Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere.
MS-ESS2.C: Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
LS4.D: Biodiversity and Humans
3-LS4.D Populations live in a variety of habitats, and change in those habitats affects the organisms living there.
Cause and Effect
Scale, Proportion, and Quantity
Systems and System Models
Stability and Change
Principle II Concept B: Methods used to extract, harvest, transport, and consume natural resources influence the geographic extent, composition, biological diversity, and viability of natural systems.
Principle III Concept A: Natural systems proceed through cycles and processes that are required for their functioning.
Principle III Concept B: Human practices depend upon and benefit from the cycles and processes that operate within natural systems.
Principle III Concept C: Human practices can alter the cycles and processes that operate within natural systems.
Principle IV Concept B: The byproducts of human activity are not readily prevented from entering natural systems and may be beneficial, neutral, or detrimental in their effect.
5.3.a Earth's Water: Students learn about the water cycle, availability of fresh water, salinity and density of water, and the interaction of humans with freshwater, coastal, and marine ecosystems.
5.3.d Our Water: Sources and Uses: Students identify sources of fresh water and describe the reservoirs of Earth’s water and the variations in the ten hydrological regions of California.
Precipitation: rain, snow, sleet, or hail that falls to the ground
Runoff: rain that does not evaporate or soak into the ground
Reservoir: a place where water is collected and stored
Wastewater: used water (often called sewage)
Storm water: water from a rain storm that washes off roads and roof tops
Watershed: an area of land where all of the water that falls on it or drains off of it goes into a particular body of water
