Overview
The skills in standard 5.1 are intended to define the “investigate” component and
the understanding of the nature of science for all of the other fifth-grade
standards. The intent of standard 5.1 is for students to continue to develop a
range of inquiry skills, achieve proficiency with those skills, and develop and
reinforce their understanding of the nature of science in the context of the
concepts developed at the fifth-grade level. It is also intended that by developing
these skills, students will achieve a greater understanding of scientific inquiry and
the nature of science and will more fully grasp the content-related concepts.

Science assumes that the natural world is understandable. Scientific inquiry can provide
explanations about nature. This expands students’ thinking from just knowledge of facts to
understanding how facts are relevant to everyday life.

Systematic investigations require standard measures and consistent and reliable tools. Metric
measures are a standard way to make measurements and are recognized around the world.

A classification key is an important tool used to help identify objects and organisms. It
consists of a branching set of choices organized in levels, with most levels of the key having two
choices. Each level provides more specific descriptors, eventually leading to identification.

A hypothesis is an educated guess/prediction about what will happen based on what you
already know and what you have already learned from your research. It must be worded so that
it is “testable.” The hypothesis can be written as an “If…, then….” statement, such as “If all light
is blocked from a plant for two weeks, then the plant will die.”

An independent variable is the factor in an experiment that is altered by the experimenter.
The independent variable is purposely changed or manipulated.

A dependent variable is the factor in an experiment that changes as a result of the
manipulation of the independent variable.

The constants in an experiment are those things that are purposefully kept the same
throughout the experiment.

A scientific prediction is a forecast about what may happen in some future situation. It is
based on the application of factual information and principles and recognition of trends and
patterns.


An inference is a tentative explanation based on background knowledge and available data.
A conclusion is a summary statement based on the results of an investigation. Scientific
conclusions are based on verifiable observations (science is empirical).

Standard 5.6
The student will investigate and understand characteristics of the ocean environment.
Key concepts include:
a) geological characteristics;
b) physical characteristics; and
c) ecological characteristics.
Overview
This standard extends the study of ecosystems to the ocean environment. It
focuses on the major descriptive characteristics of oceans. Among the concepts
are the geological characteristics of the ocean floor, the physical characteristics
of ocean water, and the ecological characteristics of communities of marine
organisms.
The Ocean

Oceans cover about 70 percent of the surface of the Earth.

Important features of the ocean floor near the continents are the continental shelf, the
continental slope, and the continental rise. These areas are covered with thick layers of
sediments (sand, mud, rocks).

The depth of the ocean varies. Ocean trenches are very deep, and the continental shelf is
relatively shallow.

Ocean water is a complex mixture of gases (air) and dissolved solids (salts, especially sodium
chloride). Marine organisms are dependent on dissolved gases for survival. The salinity of
ocean water varies in some places depending on rates of evaporation and amount of runoff from
nearby land.

The basic motions of ocean water are the waves, currents, and tides.

As the depth of ocean water increases, the temperature decreases, the pressure increases, and
the amount of light decreases. These factors influence the type of life forms that are present at
a given depth.

Plankton is tiny free-floating organisms that live in water. Plankton may be animal-like or plantlike. Animal-like plankton is called zooplankton. Plant-like plankton (phytoplankton)
carries out most of the photosynthesis on Earth. Therefore, they provide much of Earth’s
oxygen. Phytoplankton forms the base of the ocean food web. Plankton flourishes in areas
where nutrient-rich water upwells from the deep.
Page 4
Revised January, 2016
The ocean floor is much like land it is just covered with water. You would see landforms such as
mountains, valleys, hills and plains. The ocean floor has important features to include: the
continental shelf, the continental slope, the continental rise, the abyssal plain and the
ocean trenches.
Ocean Floor Feature
Continental Shelf
Description
It is at the beginning of the shore line
and covered with thick layers of mud,
sand and rocks.
Sunlight is able to shine on the
continental shelf therefore; plant and
animal life is can survive here.
Continental Slope
It is at the end of the continental shelf
and is also covered with thick layers of
mud, sand and rocks.
Continental Rise
The area that connects the continental
slope to the ocean floor and is also
covered with thick layers of mud, sand
and rocks.
Ocean Trenches
These are very deep and dark. Very
little sunlight, animal or plant life is
found in the trenches.
Abyssal Plain
These are flat areas of the ocean floor
that are covered with mud and sand.
Seamounts are also located on these
flat plains. Seamounts are formed by
erupting volcanoes.
Page 5
Revised January, 2016
Currents

Ocean currents, including the Gulf Stream, are caused by wind patterns and the differences in
water densities (due to salinity and temperature differences). Ocean currents affect the mixing
of ocean waters. This can affect plant and animal populations. Currents also affect navigation
routes.
What are currents?
Currents are ocean waters that travel in large circular patterns.
What causes currents?
There are three things that can cause currents; wind patterns, temperature, and salinity.
Causes of Currents
Wind Patterns
Winds that blow in the
same direction year
round.
Example: The Gulf
Stream located along the
east coast of the United
States in the Atlantic
Ocean.
Temperature
Salinity
Currents are created by
changes in water temperature.
Salinity is the
amount of salt in
the water. As the
sun heats the
water it
evaporates and
affects the amount
of salt in the
ocean water. Salty
water is heavy and
it sinks. Less salty
water rises to the
surface. The up
and down motion
of the salt water
creates ocean
currents.

Standard 5.7
The student will investigate and understand how Earth’s surface is constantly changing. Key concepts
include:
a) identification of rock types;
b) the rock cycle and how transformations between rocks occur;
c) Earth history and fossil evidence;
d) the basic structure of Earth’s interior;
e) changes in Earth’s crust due to plate tectonics;
f) weathering, erosion, and deposition; and
g) human impact.
Overview
This standard focuses on the constantly changing nature of Earth’s surface and
builds on concepts learned in standards. Among the important ideas presented in
this standard are the rock cycle, fossil evidence of change over time, energy from
within Earth that drives tectonic plate movement, shifting tectonic plates that
cause earthquakes and volcanoes, weathering and erosion, and human
interaction with the Earth’s surface.
The Rock Cycle
Rocks move and change over time due to heat and pressure within Earth and due to
weathering, erosion, and deposition at the surface. These and other processes
constantly change rock from one type to another.
Depending on how rocks are formed, they are classified as sedimentary (layers of sediment
cemented together), igneous (melted and cooled, e.g., lava and magma), and
metamorphic (changed by heat and pressure).
Rocks have properties that can be observed, tested, and described. Composition, grain size and
textural features, color, and the presence of fossils help with identification.
Page 9
Revised January, 2016
Rocks and other materials on Earth’s surface are constantly being broken down both chemically
and physically. The products of weathering include clay, sand, rock fragments, and soluble
substances.
Materials can be moved by water and wind (eroded) and deposited in new locations as sediment
(deposition).
Weathering is the breaking down of rocks.
Erosion is the carrying away of the rocks and materials by either wind or water.
Deposition is the depositing of rocks and materials in a new location as sediment.
Page 10
Revised January, 2016
Note:

Scientific evidence indicates the Earth is very ancient — approximately 4.6 billion years old.
The age of many rocks can be determined very reliably.

Fossils provide information about life and conditions of the past.

The Rock Cycle Never Ends!
The Earth’s Layers

Scientific evidence indicates that the Earth is composed of four concentric layers — crust,
mantle, inner core, and outer core — each with its own distinct characteristics. The outer
two layers are composed primarily of rocky material. The innermost layers are composed
mostly of iron and nickel. Pressure and temperature increase with depth beneath the surface.

Page 11
Revised January, 2016

Earth’s thermal energy causes movement of material within Earth. Large continent-size blocks
(plates) move slowly about Earth’s surface, driven by that thermal energy.

Most earthquakes and volcanoes are located at the boundaries of the plates (faults). Plates can
move together (convergent boundaries), apart (divergent boundaries), or slip past each
other horizontally (transform boundaries, also called strike-slip or sliding boundaries).

Geological features in the oceans (including trenches and mid-ocean ridges) and on the continents
(mountain ranges, including the Appalachian Mountains) are caused by current and past plate
movements.
Convergent Boundaries
When plates push
together convergent
boundaries are formed.
They cause mountain
ranges on land. Such as the
Appalachian Mountains of
Virginia.
Convergent boundaries
form trenches under water.
They force plates downward
instead of upward below
water.
Divergent Boundaries
A divergent boundary is
formed when plates
move apart. Most form
on ocean floors by
magma rising up
between two plates.
Sliding, Strike-slip or
Transform Boundaries
These boundaries are
formed when plates slide
past each other.
These boundaries cause
earthquakes.
They form volcanoes
and mountain ranges
under water.

Human Impact on the Earth
Humans have varying degrees of impact on Earth’s surface through their everyday activities. With
careful planning, the impact on the land can be controlled.
What are some ways humans’ negative impact on the land can be controlled?

Think for a moment about what it would be like without paper, napkins, toilet paper? Where do
these things come from?
o They originate from trees. Companies must begin by farming large areas of trees. In order
to control the impact on the land, it is necessary to plant and replenish what is used
What can you do? Can you think of one way humans can have a positive impact on the
land?

4th Grade Science Review Notes
for 5th Grade Parents and Students
Science: Third Nine Weeks
2015-2016
Fifth grade students will take the Virginia Standards of Learning Science Test at the end
of the fifth grade. Information addressed on the test will include information from the
fourth and fifth grade Science Standards of Learning Curriculum Framework as issued by
the Virginia Department of Education. The Curriculum Framework in its entirety can be
found at the following website:
http://www.doe.virginia.gov/testing/sol/frameworks/science_framewks/framework_science5.pdf
Standard 4.9
The student will investigate and understand important Virginia natural
resources. Key concepts include:
a)
b)
c)
d)
watershed and water resources;
animals and plants;
minerals, rocks, ores, and energy sources; and
forests, soil, and land.
Overview
Virginia has a rich variety of natural resources. These provide the raw
materials for our daily lives and sustain our economy. Natural
resources are finite and must be used wisely to ensure their
continued availability. This concept of natural resources is introduced
in 1.8 (1st grade). It is intended that students will actively develop
and utilize scientific investigation, reasoning, and logic skills (4.1) in
the context of the key concepts presented in this standard.
Virginia’s Natural Resources

Virginia is rich in a wide variety of natural resources, including forests, arable
(farmable) land, coal, sand and aggregate (rocks), wildlife, aquatic organisms, clean
water and air, and beautiful scenery.

Virginia’s water resources include groundwater, lakes, reservoirs, rivers, bays and the
Atlantic Ocean.
Groundwater -water that is found beneath Earth’s surface
Page 23
Revised January, 2016
River -a large natural stream of fresh water flowing along a definite path,
usually into the sea or ocean. Example: James River
Lake - a body of water entirely surrounded by land and unconnected to the sea
except by rivers or streams. Example: Silver Lake
Reservoir - natural or artificial lake or large tank used for collecting and storing
water. Example: King William Reservoir
Bay - is a wide indentation in a shoreline having deep water that is surrounded
by land on three sides. Example: Chesapeake Bay
Ocean – is a very large body of salt water. There are five oceans on Earth.
Example: Atlantic Ocean
What is a watershed?
A watershed is an area over which surface water (and the material it carries) flows to a single
collection place. Within the state of Virginia there are nine distinct watersheds. These nine are part
of the Chesapeake Bay Watershed which covers approximately half of Virginia’s land area. The
other two major watershed systems are the Gulf of Mexico and the North Carolina Sounds.
What is the difference between a house address and a watershed address?
A mailing address lists a house number, street, town, and state, conveying a location based upon
man-made boundaries. A watershed address lists the streams, rivers, and bay to identify a location
based upon the flow of water across a watershed. Both addresses list information in order from local
to global. Depending on the path water takes to reach the bay, a watershed address may be long or
short. Here are examples of both:
Page 24
Revised January, 2016
“We All Live Downstream”
 Students may wonder where water goes after it flows down the street during a heavy
rainstorm.
 Water travels over and through the land.
 Sewage treatment plants, homes, commercial, residential developments, farms, and factories
all have an impact on water quality.
Virginia has a great variety of plant and animal resources.
 One of the greatest negative impacts on resources, results from conditions that contribute to
increased runoff, sediment, and nutrient levels in the water. Increased runoff causes erosion
and flooding of waterways.
 The rapid water picks up and spreads pollutants.
 Erosion of exposed soil contributes sediment to the water.
 The most effective method of reducing erosion-causing runoff and pollutants entering the
water is the maintenance of vegetation along the riverbank.
 Vegetation serves as a natural filter, slowing the flow of runoff and holding the soil in place.
 Vegetation also shades the waterway and prevents the water from reaching unhealthy
temperature levels.
 Farmers who practice no-till farming and/or contour plowing help to reduce runoff and
erosion.
 Developers who maintain a vegetated buffer along waterways help to reduce the potential
runoff of pollutants and sediment.
 Contractors who use retaining fences also reduce the level of runoff and erosion.

Natural and cultivated forests are a widespread resource in Virginia.
Virginia’s Mineral Resources:
Where do minerals come from? They are mined from the earth.
What minerals can be found in Virginia? Some of Virginia’s important minerals include
limestone, granite, sand, gravel, and coal. Coal is the most important mineral resource in the state.
Why are they important? Many of Virginia’s industries and individuals depend on the mineral
resources of our state. Some of these include the transportation industry, various manufacturers,
farmers, artisans, scientists, the construction industry, and the mining industry.
Are they renewable or nonrenewable? Coal, for example, is nonrenewable. Once it is used, it is
gone forever. Therefore, we must use our resources wisely.

Virginia’s soil and land support a great variety of life, provide space for many economic
activities, and offer a variety of recreational opportunities.
