Scientific
explanations emphasize evidence, have logically consistent arguments,
and use scientific principles, models, and theories. The scientific
community accepts and uses such explanations until displaced by better
scientific ones. When such displacement occurs, science advances.
(5-8) |
X |
Science
advances through legitimate skepticism. Asking questions and querying
other scientists' explanations is part of scientific inquiry. Scientists
evaluate the explanations proposed by others by examining evidence,
comparing evidence, identifying faulty reasoning, pointing out statements
that go beyond evidence, and suggesting alternative explanations for
the same observations. (5-8) |

Scientific
investigations sometimes result in new ideas and phenomena for study,
generate new methods or procedures for an investigation, or develop
new data-collection technologies. All of these can lead to new investigations.

MOTIONS
AND FORCES |
The
motion of an object can be described by its position, direction
of motion, speed. The motion can be measured and represented on
a graph. (5-8) |

An
object that is not being subjected to a force will continue to move
at a constant speed and in a straight line. (5-8) |
X |
If
more than one force acts on an object along a straight line, then
the forces will reinforce or cancel one another, depending on their
direction and magnitude. Unbalanced forces will cause changes in the
speed or direction of an object's motion. (5-8) |

LIFE SCIENCE
THE
CHARACTERISTICS OF ORGANISMS |
Organisms
have basic needs. For example, animals need air, water and food; plants
require air, water, nutrients, and light. Organisms can survive only
in environments in which their needs can be met. The world has many
different environments, and distinct ones support the life of different
types of organisms. (K-4) |

Many
characteristics of an organism are inherited from the parents, but
others result from an individual's interactions with the environment.
Inherited characteristics include the color of flowers and the number
of limbs of an animal. Other features are learned through interactions
with the environment and cannot be passed on to the next generation.

animals depend on plants. Some animals eat plants for food. Others
eat animals that eat plants. (K-4) |
X |
An
organism's behavior patterns are related to the nature of that organism's
environment, including the kinds and number of other organisms present,
the availability of food and resources, and the physical characteristics
of the environment. When environment changes, some plants and animals
survive and reproduce, and others die or move to new locations. (K-4) |

REPRODUCTION
AND HEREDITY |
Reproduction
is a characteristic of all living systems; because no individual organism
lives forever, reproduction is essential to the continuation of every
species. Some organisms reproduce asexually. Other organisms reproduce
sexually. (5-8) |
X |
In
many species, including humans, females produce eggs and males produce
sperm. Plants also produce sexually?the egg and sperm are produced
in the flowers of flowering plants. An egg and sperm unite to begin
development of a new individual. That individual receives genetic
information from its mother (via the egg) and its father (via the
sperm). Sexually produced offspring never are identical to either
of their parents. (5-8) |
X |
Every
organism requires a set of instructions for specifying its traits.
Heredity is the passage of these instructions from one generation
to another. (5-8) |
X |
The
characteristics of an organism can be described in terms of a combination
of traits. Some are inherited and others result from environmental
interactions. (5-8) |

REGULATION
AND BEHAVIOR |

organisms must be able to obtain and use resources, grow, reproduce,
and maintain stable internal conditions in a constantly changing external
environment. (5-8) |

|
Regulation
of an organism's internal environment involves sensing the internal
environment and changing physiological activities to keep conditions
within range required to survive. (5-8) |
|
Behavior
is one kind of response an organism can make to an internal or environmental
stimulus. A behavioral response requires coordination and communication
at many levels, including cells, organ systems, and whole organisms.
Behavioral response is determined in part by heredity and in part
from experience. (5-8) |
What
is roosting? |
An
organism's behavior evolves through adaptation to its environment.
How a species moves, obtains food, reproduces, and responds to danger
are based in the species' evolutionary history. (5-8) |

POPULATIONS
AND ECOSYSTEMS |
A
population consists of all individuals of a species that occur together
at a given place and time. All populations living together and the
physical factors with which they interact compose an ecosystem. (5-8)
|
Eastern
Flock: A "Nonessential," Experimental Population
Entire
Whooping Crane study |
Populations
of organisms can be categorized by the function they serve in an ecosystem.
Plants and some microorganisms are producers?they make their own food.
All animals, including humans, are consumers, which obtain food by
eating other organisms. Decomposers, primarily bacteria and fungi,
are consumers that use waste materials and dead organisms for food.
Food webs identify the relationships among producers, consumers, and
decomposers in an ecosystem. (5-8) |
X |
For
ecosystems, the major source of energy is sunlight. Energy entering
ecosystems as sunlight is transferred by producers into chemical energy
through photosynthesis. That energy then passes from organism to organism
in food webs. (5-8) |
X |
The
number of organisms an ecosystem can support depends on resources
available and abiotic factors, such as quantity of light and water,
range of temperatures, and soil composition. Given adequate biotic
and abiotic resources and no disease or predators, populations increase
at rapid rates. Lack of resources and other factors, such as predation
and climate, limit the growth of populations in specific in certain
niches. (5-8) |
X |
DIVERSITY
AND ADAPTATIONS |
Millions
of species of animals, plants, and microorganisms are alive today.
Although different species might look dissimilar, the unity among
organisms becomes apparent from an analysis of internal structures,
the similarity of their chemical processes, and the evidence of common
ancestry. (5-8) |
X |
Biological
evolution accounts for the diversity of species through gradual processes
over many generations. Species acquire many of their unique characteristics
through biological adaptation, which involves the selection of naturally
occurring variations in populations. Biological adaptations include
changes in structures, behaviors, or physiology that enhance survival
and reproductive success in a particular environment. (5-8) |
X |
Extinction
of a species occurs when the environment changes and the adaptive
characteristics of a species are insufficient to allow its survival.
Fossils indicate that many organisms that lived long ago are extinct.
Extinction of species is common; most of the species that have lived
on the earth no longer exist. (5-8) |

CHANGES
IN THE EARTH AND SKY |
The
surface of the earth changes. Some changes are due to slow processes,
such as erosion and weathering, and some changes are due to rapid
processes, such as landslides, volcanic eruptions, and earthquakes.
(K-4) |
X |
Weather
changes from day to day and over the seasons. Weather can be described
by measurable quantities, such as temperature, wind direction and
speed, and precipitation. (K-4) |
Ultralight
Pilot's Checklist: Weather or Not? |
Objects
in the sky have patterns of movement. The sun, for example, appears
to move across the sky in the same way every day, but its path changes
slowly over the seasons. The moon moves across the sky on a daily
basis much like the sun. The observable shape of the moon changes
from day to day in a cycle that lasts about a month. (K-4) |
X |
STRUCTURE
OF THE EARTH SYSTEM |
Soil
consists of weathered rocks and decomposed organic material from
dead plants, animals, and bacteria. Soils are often found in layers,
with each having a different chemical composition and texture. (5-8)
|
X |
Water,
which covers the majority of the earth's surface, circulates through
the crust, oceans, and atmosphere in what is known as the "water cycle."
Water evaporates from the earth's surface, rises and cools as it moves
to higher elevations, condenses as rain or snow, and falls to the
surface where it collects in lakes, oceans, soil, and in rocks underground.

X |
Clouds,
formed by the condensation of water vapor, affect weather and climate.

Entire

Science
requires different abilities, depending on such factors as the field
of study and type of inquiry. Science is very much a human endeavor,
and the work of science relies on basic human qualities, such as reasoning,
insight, energy, skill, and creativity?as well as on scientific habits
of mind, such as intellectual honesty, tolerance of ambiguity, skepticism,
and openness to new ideas. (5-8) |
Entire
Whooping Crane study |
NATURE
OF SCIENCE |
Scientists
formulate and test their explanations of nature using observation,
experiments, and theoretical and mathematical models. Although all
scientific ideas are tentative and subject to change and improvement
in principle, for most major ideas in science, there is much experimental
and observational confirmation. Those ideas are not likely to change
greatly. Scientists do and have changed their ideas about nature
when they encounter new experimental evidence that does not match
their existing explanations. (5-8) |
X |
In
areas where active research is being pursued and in which there
is not a great deal of experimental or observational evidence and
understanding, it is normal for scientists to differ with one another
about the interpretation of the evidence or theory being considered.
Different scientists might publish conflicting experimental results
or might draw different conclusions from the same data. Ideally,
scientists acknowledge such conflict and work towards finding evidence
that will resolve their disagreement. (5-8) |
X |
It
is part of scientific inquiry to evaluate the results of scientific
investigations, experiments, observations, theoretical models, and
the explanations proposed by other scientists. Evaluation includes
reviewing experimental procedures, examining the evidence, identifying
faulty reasoning, pointing out statements that go beyond the evidence,
and suggesting alternative explanations for the same observations.
Although scientists may disagree about explanations of phenomena,
about interpretations of data, or about the value of rival theories,
they do agree that questioning, response to criticism, and open communication
are integral to the process of science. As scientific knowledge evolves,
major disagreements are eventually resolved through such interactions
between scientists. (5-8) |
