Grades K - 4
Educational experiences in Grades K-4 will assure that students:
- recognize (in Grades K-2) that water can exist as a solid,
liquid or gas and can be changed from one form to the other;
- recognize (in Grades K-2) that water on Earth exists in different
forms (e.g., rain, snow, ice, surface water);
recognize (in Grades K-2) that plants and animals need water
to live;
- recognize that water can exist as a gas in the air and can
reappear as a liquid, if cooled, or as a solid, if cooled below
the freezing point of water;
- recognize that three-fourths of the Earth’s surface is
covered by water;
- identify major sources of water (e.g., oceans, glaciers, rivers,
groundwater, atmosphere);
- recognize the importance and uses of water (e.g., drinking,
washing, irrigating); and
- recognize that water is essential to life.
Grades 5 - 8
Educational experiences in Grades 5 - 8 will assure that students:
- recognize how the cycling of water in and out of the atmosphere
plays an important role in deter-mining climatic patterns and
is responsible for constantly changing the phase and location
of water;
- recognize that water falling to Earth flows over the surface
as runoff and collects in ocean basins, rivers, lakes, icecaps
and underground; and
- recognize that water stored underground (subsurface) and water
stored above ground (surface) form a continuum, each supplying
water to the other.
Grades 9 - 12
Educational experiences in Grades 9 - 12 will assure that students:
- recognize that the ocean is a complex system of important
chemicals which cycle through other Earth systems over various
periods of time;
- recognize that fresh water is limited in supply and can be
depleted or polluted, becoming unavailable or unsuitable for
life;
- explain interactions between water and other Earth systems
(e.g., the biosphere, lithosphere and atmosphere);
- recognize that water is an erosional force that can rapidly
and slowly change the landscape;
- describe how the oceans absorb and release heat energy that
moderates the Earth’s climate; and
- describe how the physical and chemical properties of water
affect the environment and life.
