TOPIC
POWER OBJECTIVE #1
 Cycles and Patterns of Earth and the Moon
Describe the relative patterns of motion and positions of the Earth,
moon, and sun which cause solar and lunar eclipses, tides and phases of
the moon. (7.ESS.1)
SUPPORTING INDICATORS
7.ESS.1.a Investigate the moon’s orbit and its change of position relative to the Earth
and sun which result in different parts of the moon being visible from Earth.
7.ESS.1.b Design a model that proves a solar eclipse is when the Earth moves into the
shadow of the moon; a lunar eclipse is when the moon moves into the shadow of the
Earth.
7.ESS.1.c Compare daily oceanic currents; spring and neap tides caused by the
gravitational force between the Earth and the moon.
POWER OBJECTIVE #2
Analyze how thermal-energy transfers in the ocean and the atmosphere
contribute to the formation of currents, which influence global climate
patterns. (7.ESS.2)
SUPPORTING INDICATORS
7.ESS.2.a Recognize that sun is the major source of energy for wind, air and ocean
currents and the hydrologic cycle.
7.ESS.2.b Trace how thermal energy transfers occur within the atmosphere and ocean,
causing currents to form.
7.ESS.2.c Identify how large bodies of water can influence weather and climate.
7.ESS.2.d Investigate factors other than thermal energy that will influence ocean
currents, such as water density, mineral content, ocean floor topography and the Earth’s
rotation.
7.ESS.2.e Distinguish how regional temperature and precipitation contribute to the
identification of climatic zones.
POWER OBJECTIVE #3
Recognize and compare how the atmospheric properties at different
elevations contain a mixture of gases that cycle through the lithosphere,
biosphere, hydrosphere and atmosphere. (7.ESS.3)
SUPPORTING INDICATORS
7.ESS.3.a Describe the effect the force of gravity has on the atmosphere.
7.ESS.3.b Illustrate the movement of biogeochemical cycles , the specific elements or
molecules through the lithosphere, biosphere, hydrosphere and atmosphere.
7.ESS.3.c Identify patterns that define the layers of the atmosphere which have specific
properties, such as temperature, chemical composition and physical characteristics.
POWER OBJECTIVE #4
Describe the hydrologic cycle and how it illustrates the changing states of
water as it moves through the lithosphere, biosphere hydrosphere and
atmosphere. (7.ESS.4)
SUPPORTING INDICATORS
7.ESS.4.a Explain how thermal energy is transferred as water changes state throughout
the cycle.
7.ESS.4.b Analyze how cycling of water in the atmosphere is an important part of
weather patterns on Earth.
7.ESS.4.c Prove that the rate at which water flows through soil and rock is dependent
upon the porosity and permeability of the soil or rock.

 Conservation of Mass and Energy
Explain how properties of matter are determined by the arrangement of
atoms. (7.PS.1)
SUPPORTING INDICATORS
7.PS.1.a
Grading
Period

Analyze how the elements are organized into families with similar properties.
7.PS.1.b Explain how substances interact to form new substances, and the properties of
the new substances may be very different from those of the old, but the amount of mass
does not change.
7.PS.1.c Compare acids and bases which are identified by their pH.
7.PS.1.d Investigate how chemical and physical changes occur on a continuum and no
distinct lines separate the two.
POWER OBJECTIVE #6
Explain how energy can be transformed or transferred but is never lost.
(7.PS.2)
SUPPORTING INDICATORS
7.PS.2.a Identify how matter and energy cannot get into or out of a closed system, and
how matter and energy can be transferred into and out of an open system.
7.PS.2.b Differentiate how some systems are more energy efficient than others.
POWER OBJECTIVE #7
Describe how energy can be transferred in a variety of ways. (7.PS.3)
SUPPORTING INDICATORS
7.PS.3.a Prove how mechanical energy can be transferred when objects push or pull on
each other over a distance.
7.PS.3.b Describe the transfer energy from electromagnetic waves when they interact
with matter.
7.PS.3.c Describe and illustrate how thermal energy can be transferred through
radiation, convection and conduction.
7.PS.3.d Analyze how electrical energy is transferred when an electrical source is
connected in a complete electrical circuit to an electrical device.

POWER OBJECTIVE #8
 Cycles of Matter and Flow of Energy
Describe how matter is transferred continuously between one organism
to another and between organisms and their physical environments.
(7.LS.1)
SUPPORTING INDICATORS
7.LS.1.a Explain how plants use energy in light to make sugar (photosynthesis) which
may be used immediately or stored for later use.
