GRADE 8 I. HISTORY AND NATURE OF SCIENCE
A. Scientific World View
The student will understand that science is a way of knowing about the world
that is characterized by empirical criteria, logical argument and skeptical review.
1. The student will explain and give examples of how science can be
used to make informed ethical decisions by identifying likely
consequences of particular actions.
2. The student will explain the development, usefulness and limitations
of scientific models in the explanation and prediction of natural
phenomena.
GRADE 8 I. HISTORY AND NATURE OF SCIENCE
B. Scientific Inquiry
The student will understand that scientific inquiry is used by scientists to
investigate the natural world in systematic ways.
1. The student will know that scientific investigations involve the
common elements of systematic observations, the careful collection of
relevant evidence, logical reasoning and innovation in developing
hypotheses and explanations.
2. The student will describe how scientists can conduct investigations in
a simple system and make generalizations to more complex systems.
GRADE 8 I. HISTORY AND NATURE OF SCIENCE
B. Scientific Inquiry
The student will use multiple skills to design and conduct scientific investigations.
1. The student will specify variables to be changed, controlled and measured.
2. The student will use sufficient trials and adequate sample size to ensure reliable data.
3. The student will use appropriate technology and mathematics skills to
access, gather, store, retrieve and organize data.
GRADE 8 I. HISTORY AND NATURE OF SCIENCE
C. Scientific Enterprise
The student will know that science and technology are human efforts that both
influence and are influenced by civilizations and cultures worldwide.
1. The student will evaluate the credibility and validity of scientific and
technological information from various sources.
GRADE 8 I. HISTORY AND NATURE OF SCIENCE
D. Historic Perspectives
The
student will understand how scientific discovery, culture, societal
norms and technology have influenced one another in different time
periods.
1. The student will relate personal experiences in scientific investigation
to the experiences of scientists throughout history.
2. The student will cite examples of how science and technology
contributed to changes in agriculture, manufacturing, sanitation,
medicine, warfare, transportation, information processing or
communication.
GRADE 8 III. EARTH AND SPACE SCIENCE
A. Earth Structure and Processes
The student will identify Earth’s composition, structure and processes.
1. The student will explain how earthquakes, volcanoes, sea-floor
spreading and mountain building are evidence of the movement of crustal
plates.
2. The student will describe how features on the Earth’s surface are
created and constantly changing through a combination of slow and rapid
processes of weathering, erosion, sediment deposition, landslides,
volcanic eruptions and earthquakes.
3. The student will describe the various processes and interactions of
the rock cycle.
4. The student will interpret successive layers of sedimentary rocks and
their fossils to document the age and history of the Earth.
5. The student will recognize that constructive and destructive Earth
processes can affect the evidence of Earth’s history.
6. The student will classify and identify rocks and minerals using
characteristics including but not limited to density, hardness and streak.
GRADE 8 III EARTH AND SPACE SCIENCE
A. Earth Structure and Processes
The student will investigate the impact humans have on the environment.
1. The student will identify and research an environmental issue and
evaluate its impact.
GRADE 8 III. EARTH AND SPACE SCIENCE
B. The Water Cycle, Weather and Climate
The student will investigate how the atmosphere interacts with the Earth system.
1. The student will define radiation, conduction and convection and explain their effects on weather and climate.
2. The student will identify the forces that create currents and layers in the Earth’s atmosphere and water systems.
3. The student will describe the effect of Earth’s rotation on the winds and ocean currents.
4. The student will collect and use data to predict the weather.
5. The student will identify the composition and structures of the atmosphere.
6. The student will describe climate changes that have occurred over time.
GRADE 8 III. EARTH AND SPACE SCIENCE
C. The Universe The student will compare objects in the solar system and explain their interactions with the Earth.
1.
The student will recognize that the sun is the principal energy source
for the solar system and that this energy is transferred in the form of
radiation.
2. The student will explain how the combination of the Earth's tilted
axis and revolution around the sun causes the progression of seasons
and weather patterns.
3. The student will compare and contrast the planets, taking into
account their composition, mass and distance from the sun and recognize
the conditions that have allowed life to flourish on Earth.
4. The student will use the predictability of the motions of the Earth,
and sun to explain the length of day, length of year, phases of the
moon, eclipses, tides and shadows.
GRADE 8 III. EARTH AND SPACE SCIENCE
C. The Universe The student will describe the composition and structure of the universe.
1.
The student will recognize that the universe consists of many billions
of galaxies, each containing many billions of stars and that there are
vast distances that separate these galaxies and stars from one another.
2. The student will recognize that the sun is a medium-sized star and
is the closest star to Earth. It is the central and largest body in the
solar system and is one of billions of stars in the Milky Way Galaxy.
