Science Curriculum: Grade 5
In Grade 5, students examine the nature of science within more sophisticated aspects of the solar system. In doing so, they will gain a deeper understanding of less easily
observable--but no less real--aspects of weather. Students expand on this understanding of the solar system and weather, to encompass study of other members of the
ecosystem and their participation within the larger system. The year concludes with a study of food and nutrition.

A. Celestial objects that are visible in
the sky with the naked eyes are
stars, the Moon, planets, meteors,
and comets.
B. Our solar system consists of the
Sun, the planets, their moons, and
other smaller objects that orbit the
sun (asteroids, comets).
C. A planet is round, orbits the Sun
and has cleared its region of the
solar system along its orbit of
smaller objects.
D. A dwarf planet is an object that
orbits the Sun and has enough
gravity to be spherical, but the area
of its orbit is not cleared.
E. The Sun has no solid surface.
Hydrogen makes up about three-
fourths of its mass, and helium
From Genesis, we learn
that God created all things
from nothing to reveal His
goodness and to form a
single web of life.
Creation is to be respected
as sacred.
The signs and symbols of
the sacraments are drawn
from creation and human
culture.
The whole of creation and
the value of all living and
non-living things within it
are essential to the study of
science. Understanding the
beauty of creation and how
life interacts with the
environment is rooted in
the values of stewardship,
Magnitude and Scale: The
groupings of magnitude of
size, time, frequency, and
pressures or other units of
measurement into a series
of relative order provides a
useful way to deal with the
immense range and the
changes in scale that affect
the behavior and design of
systems. (A, B)
Application: Telescopes

The inner planets are small and
dense and have rocky surfaces.
The inner planets differ in size and
composition as well as distance
from the sun.
G. The four outer planets are:
Jupiter, Saturn, Uranus, and
Neptune. The outer planets are
much larger and more massive
than Earth, but they do not have
solid surfaces. They are often
called gas giants because of their
size and the presences of hydrogen
and helium. All of these planets
have many moons and are also
surrounded by a set of rings (thin
disk of small particles of ice

commonalities that exist
among all systems and how
parts of a system interrelate
and combine to perform
specific functions. (N,X-

Application: Our solar
system consists of the sun
and all the things bound to
it by gravity.

a figure, animal or object.
O. The apparent motions of the Sun,
Moon, planets, and stars across the
sky can be explained by Earth's
rotation and revolution about the
Sun.
P. Rotation is the spinning of Earth
on its axis (an imaginary line that
passes through Earth's center and
the North and South poles).
Q. Earth's rotation causes the length
of one day to be approximately 24

Earth's rotation causes day and
night as different sides of Earth
face toward and away from the
Sun.
R. Revolution is the movement of
one object around another. The
Earth's complete revolution around
the Sun defines the length of the
year as 365 1/4 days.
S. As the Earth revolves around the
Sun, along its east-west path, the
Sun’s apparent altitude changes.
During the winter, the Sun’s
altitude appears lower than in the
summer sky.
T. Earth has seasons because its axis
is tilted from its vertical as it
revolves around the Sun. When its
tilt allows the northern
hemisphere to receive the most
solar radiation and heating, this
marks the beginning of summer.
When the northern hemisphere
receives the least solar radiation
and heat, the first day of winter is
marked. The seasons are in
reverse in the southern
hemisphere. U. Gravity is a force that attracts all
objects toward each other.
V. Inertia is the tendency of an
object to resist a change in motion.
20. Compose a list of items

W. Newton concluded that inertia and
gravity combine to keep Earth in
orbit around the sun and the Moon
in orbit around Earth.
X. The Moon shines because of
reflected light from the Sun.
Y. The phases of the Moon
(observed from Earth) are caused
by the motions of the Moon
around Earth and the relative
position of the Sun. As the moon
orbits Earth, its position and the
amount of reflected light from the
Sun changes. The phase of the
Moon seen depends on how much
of the sunlight side of the Moon is
observed.
Z. The force of gravity (the pull of
the Moon on Earth) is the main
cause of tides on Earth.
Scientists are constantly
discovering information about new
planets and moons due to today's
space-based telescopes and space
probes.

F. The uneven heating of Earth's
surface is the cause of weather.
G. The Sun’s energy drives the
movement of water through
earth's systems; this movement is
called the water cycle.
H. In the water cycle, water vapor
enters the atmosphere by
evaporation (molecules of
liquid water escape into the air
after becoming water vapor)
from the oceans and other bodies

becomes liquid water).
I. Some of the water vapor in the
atmosphere condenses to form
clouds. Rain and snow fall from
the clouds toward the surface as
precipitation.
J. There are three types of
precipitation: rain, sleet, and
snow.

O. Maritime air masses form over
the ocean and can be very
humid. Continental air masses
form over land, and are drier
than maritime air masses.
Tropical air masses are warm,

We form spiritual
communities to support
and encourage one another
in the church and to receive
the blessings of god
through His word and the
Sacraments.
In some regions of the
world, there are places with
ample/scarce resources.
Christians can help people
in disadvantaged lands.
Through the sacraments,
we are fed and nourished
body, soul and spirit. The
Church celebrates Christ’s
saving action in our lives.
By preparing for and
receiving the sacraments
prayerfully, our
relationship with the Risen
Lord is deepened, and we
are strengthened to live the
Christian life more fully.
Magnitude and Scale: The
groupings of magnitude of

measurement into a series of
relative order provides a useful
way to deal with the immense
range and the changes in scale
that affect the behavior and
design of systems. (U)
Application: Ecosystems can
vary in size. They can be as
small as a puddle or as large
as the Earth.

Science Curriculum: Grade 6
In Grade 6, students examine various properties of matter in greater depth considering the Earth’s lithosphere as foundation for a study of the rock cycle. Students analyze
fossils to gain a better sense of the historical Earth. Energy, friction and force are considered at a deeper level and are examined from a contextual perspective in light of
machines that students encounter regularly. This builds upon the basic knowledge of energy students gained in grades 2-4. A unit on light and sound exposes students to a
more in depth analysis of energy as revealed through these two means. The year concludes with the study of the diversity of all life, which directly correlates to the prior
unit on light—the energy upon which much of non-human life depends.

CONCEPTS SKILLS
A. Classification systems are not
part of nature. Rather, they are
frameworks created by biologists
for describing the vast diversity
of organisms
B. Living systems at all levels of
organization demonstrate the
complementary nature of
structure and function. Important
levels include cells, tissues,
organs, organ systems, and
whole organisms.
C. Living things are classified by
shared characteristics on the
cellular and organism level.
D. All organisms are composed of
cells—the fundamental unit of
life. Some organisms are single
cells; other organisms are multi
cellular.
E. When classifying organisms,
biologists consider details of
Belief in the inherent
dignity of the human
person is the foundation of
all Catholic social
teaching. Human life is
sacred, and the dignity of
the human person is the
starting point for a moral
vision for society. This
principle is grounded in the
idea that the person is
made in the image of God.
The person is the clearest
reflection of God among
us.
Human life must be
respected and protected
from the moment of
conception to natural
death.
From the first moment of
existence, a human being
must be recognized as
having the rights of a
Systems Thinking: Through
systems thinking, people can
recognize the commonalities that
exist among all systems and how
parts of a system interrelate and
combine to perform specific
functions. (A-H)
Application: Cells have the same
needs and perform the same
functions as more complex
organisms.
Equilibrium and Stability:
Equilibrium is a state of stability
due to either a lack of change
(static equilibrium) or a balance
between opposing forces
(dynamic equilibrium). (I, J)
Application: Plant and animal
cells break down sugar and
oxygen into carbon dioxide
and water to obtain energy
(cellular respiration).
Models: are simplified

1. Observe and describe the
first developmental
stages of a plant and
recognize that seeds are
living organisms in a
dormant state.
2. Conduct investigations to
understand how the
vascular system
transports water
throughout a plant and
how stomates on leaves
regulate the rate of water
flow through a plant.
3. Investigate the
reproductive systems in
flowers to understand the
origin of seeds and
explore plant adaptations
for seed dispersal.
4. Dissect seeds to discover

structures.
F. Biological classification systems
are arranged from general
(kingdom) to specific (species).
G. One of the most general
distinctions among organisms is
between plants, which use
sunlight to make their own food,
and animals, which consume
energy-rich foods. Some kinds
of organisms, many of them
microscopic, cannot be neatly
classified as either plants or
animals
H. All living organisms require
energy to survive and exhibit
certain common characteristics.
I. The amount of energy needed
and the methods for obtaining
this energy vary among cells.
J. Some cells use oxygen to release
energy stored in food.
K. Producers, herbivores,
consumers, decomposers, and
consumers obtain energy
differently.
L. Food provides molecules that
serve as fuel and building
materials for all organisms.
person.
Life and physical health
are precious gifts entrusted
to us by God. We must
take reasonable care of
them, taking into account
the needs of others and the
common good.
The virtue of temperance
disposes us to avoid every
kind of excess: the abuse of
food, alcohol, tobacco, or
medicine.
Above all else, we are one
human family. Catholic
teaching proclaims that no
matter our national, racial,
ethnic, economic or
ideological differences, we
have a global commitment
to love our neighbors and
to work for justice.
We also have a
commitment to work
towards a just, even and
fair development of our
world, where no one
society is exalted
materially above the rest,
and no other society is left,
quite literally, in the dust.
Development must respect
the rights of all nations and
structures, or systems, used in
analysis, explanation, or design.

energy and nutrients for growth
and development. Nutrition
requirements vary with body
weight, age, activity, and body
functioning.

Science Curriculum: Grade 7
In Grade 7 students again examine the nature of science and do so in the context of systems of the body and the highly sophisticated adaptive nature of the human. A deep
connection is made between the unique human experiences of students in relationship to all other aspects of the Earth; this unit enables students to contextualize a very
profound sense of the interdependence of all life. Students analyze the history of the Earth and its components, and compliment this new understanding with a concluding
unit on an introduction to chemistry.

B. Cells provide structure and carry
on major functions to sustain
life. These cells are microscopic
in size.
C. The way cells function in living
things is similar. They grow,
divide, and produce more cells.
D. Cells take in nutrients that are

a cell wall and or chloroplasts.
F. Some organisms are single cells;
others are multi-cellular.
The sacraments nourish our
souls.
Matthews Gospel is
sometimes called ―The
Gospel of the Church,‖
because the community of
disciples is presented as the
nucleus of the Kingdom of
God. Matthew 18:20
The Catholic Church has a
hierarchy – Pope, College
of Cardinals, Bishops,
Priests.
John 15: ―I am the vine….‖
The Eucharist is the
summit and source of
Christian life.
We are made in the image
and likeness of God. God
is the basis of our respect
for ourselves and others.
Magnitude and Scale: The
grouping of magnitudes of size,
time, frequency, and pressures or
other units of measurement into
a series of relative order
provides a useful way to deal
with the immense range and the
changes in scale that affect
behavior and design of systems.
(A-F)
Application: Microscopes
enable us to view extremely
small organisms and their
motion.
Systems Thinking: Through
systems thinking, people can
recognize the commonalities that
exist among all systems and how
parts of a system interrelate and
combine to perform specific
functions. (G, H)
Application: Cell theory is based
on the smallest basic unit of the
cell from which tissues and
organs are composed.

structures. These organized
groups of tissues are responsible
for a plant’s life activities.
I. Specialized cells perform
specialized functions in
multicellular organisms. Groups
of specialized cells cooperate to
form a tissue, such as muscle.
J. Different tissues are grouped
together to form larger
functional units called organs.

Application: An anatomical
model of the human body is
typically to scale and helps to
clarify how the body is
organized internally.
Equilibrium and Stability:
Equilibrium is a state of stability
due either to a lack of changes
(static equilibrium) or a balance
between opposing forces
(dynamic equilibrium).

sex cells to begin the
development of a new
individual. In many species,
including plants and humans,
eggs and sperms are produced.
O. Fertilization and/or
development in organisms may
be internal or external.
P. The male sex cell is the sperm.
The female sex cell is the egg.
The fertilization of an egg by a
sperm results in a fertilized egg.
Q. In sexual reproduction typically
half of the genes come from each
parent. Sexually produced
offspring are not identical to
either parent.
R. Multicellular organisms exhibit
complex changes in
development that begins after
fertilization. The fertilized egg
undergoes numerous cellular
divisions that will result in a
multicellular organism, with
each cell having identical genetic
information.
19. Explain how to use a
Punnett Square.
20. Identify and describe
human genetic disorders.
234
S. In humans, the fertilized egg
grows into tissues that develop
into organs and organ systems
before birth.
T. Various body structures and
functions change as an organism
goes through its life cycle.
U. Pattern of development vary
among animals and plants.
V. In some animal species the
young resemble the adult, while
in others they do not. Some
insects and amphibians undergo
metamorphosis as they mature.
W. In seed bearing plants, seeds
contain food for early
development. Their later
development into adulthood is
characterized by patterns of
growth from species to species.
X. In multicellular organisms, cell
division is responsible for
growth, maintenance, and repair.
In some one celled organisms,
cell division is a method of
asexual reproduction.
Y. In one type of cell division,
chromosomes are duplicated and
then separated into two identical
and complete sets to be passed to
235
each of the two resulting cells. In
this type of cell division, the
heredity information is identical
in all the cells that result
(mitotic cell division).
Z. Meiotic cell division accounts
for the production of egg and
sperm cells containing one-half
of the heredity information.
AA. Cancers are a result of
abnormal cell division.
BB. Genetic traits are passed on
from one generation to another.
CC. Some genes are recessive
and some are dominant.
DD. The probability of traits
being expressed can be
determined using models of
genetic inheritance. Some
EE. Models of prediction are
pedigree charts and Punnett
squares.
FF. A pedigree chart is a diagram
that shows the occurrence of a
genetic trait in several
generations of a family.
GG. A Punnett square is a chart
that indicates possible gene
combinations.
236
HH. The processes of sexual
reproduction and mutation gave
rise to a variety of traits within a
species.

occurs when the environment
changes and the adaptive
characteristics of a species are
insufficient to permit its survival.
