Building
upon knowledge and skills gained in preceding
grades,
by the end of Grade 4, students will:
Standard 5.8
(Earth
Science) All students will gain an understanding
of the structure, dynamics, and geophysical
systems of earth.
Standard 5.8.3.A
Earth’s
Properties and Materials
Standard 5.8.3.A.1
Observe
that most rocks and soils are made of several
substances or minerals.
Standard 5.8.3.A.2
Observe
that the properties of soil vary from place
to place and will affect the soil’s ability
to support life.
Standard 5.8.3.A.3
Recognize
that fossils provide evidence about the plants
and animals that lived long ago and the nature
of the environment at that time.
Standard 5.8.3.B
Atmosphere
and Water
Standard 5.8.3.B.1
Recognize
that air is a substance that surrounds us,
takes up space, and moves around us as wind.
Standard 5.8.3.B.2
Recognize
that most of Earth’s surface is covered
by water and be able to identify the characteristics
of those sources of water.
· oceans
· rivers
· lakes
· underground sources
· glaciers
Standard 5.8.3.B.3
Observe
weather changes and patterns by measurable
quantities such as temperature, wind direction
and speed, and amounts of precipitation.
Standard 5.8.3.B.4
Observe
that when liquid water disappears, it turns
into a gas (vapor) in the air and can reappear
as a liquid when cooled, or as a solid if cooled
below its freezing point.
Standard 5.8.3.B.5
Observe
that rain, snow, and other forms of precipitation
come from clouds, but that not all clouds produce
precipitation.
Standard 5.8.3.B.6
Recognize
that clouds and fog are made of tiny droplets
of water and possibly tiny particles of ice.
Standard 5.8.3.C
Processes
that Shape the Earth
Standard 5.8.3.C.1
Recognize
that some changes of the Earth’s surface
are due to slow processes such as erosion and
weathering, and some changes are due to rapid
changes such as landslides, volcanic eruptions,
and earthquakes.
Standard 5.8.3.C.2
Recognize
that moving water, wind, and ice continually
shape the Earth’s surface by eroding
rock and soil in some areas and depositing
them in other areas.
Standard 5.8.3.D
How
We Study the Earth
Standard 5.8.3.D.1
Use
maps to locate and identify physical features
on the Earth.
