6th Grade SOL Review
Unit 1 – Scientific Method
Unit 2 - Matter
Unit 3 – Properties of Water
• Adhesion vs. Cohesion
• Adhesion – water sticking to other things
• Cohesion – water sticking to other water
molecules
Surface Tension
Capillary Action
Changing States
Review Questions
• What causes water to change states of
matter?
• Temperature
• Water is often called the universal
solvent. Why
• A large number of substances will dissolve
in water.
• What is it called when water goes from
a liquid to a gas?
• Evaporation
Unit 4 Weather and Atmosphere
Instruments
• Barometer
• Measures air
pressure
• Drop in pressure
means precipitation
is coming
Anemometer
• Measures wind
speed
Thermometer
• Measures
temperature
Weather Vane
• Measures wind
direction
Sling Psychrometer
• Measure humidity
Hygrometer
• Measure humidity
Review Questions
• What instrument measures temperature?
• Thermometer
• What instrument s measure humidity?
• Hygrometer and Sling Psychrometer
• What instrument measures wind speed?
• Anemometer
• What instrument measures wind direction?
• Weather Vane
• What instrument measures air pressure?
• Barometer
Types of Clouds
Review Questions
•
•
•
•
•
What are the normal fluffy clouds?
Cumulus
What are the wispy high-level clouds?
Cirrus
What are the layered clouds that are
associated with precipitation?
• Stratus
• What are the fluffy clouds associated
with precipitation?
• Cumulonimbus
Review Questions
• Which layer of the atmosphere has the
most mass?
• Thermosphere
• Which layer of the atmosphere has
weather and clouds?
• Thermosphere
• What layer of the atmosphere has the
ozone layer?
• Stratosphere
The Water Cycle and the Sun
• The Sun powers the
water cycle.
• Solar power causes
water in the ocean to
evaporate (3) ,
condense (2) into
clouds and fall back
to Earth.
Earth’s shape and tilt
• Earth is round.
• Different parts get
different amounts of
sunlight.
• The equator gets
the most direct
sunlight.
• The poles get
indirect sunlight.
Air pressure and Wind
• Wind is moving air.
• Differences in air
pressure cause wind.
• Warmer areas have low
pressure.
• Cooler areas have high
pressure.
• Air moves from high
pressure areas into low
pressure areas.
Sea Breezes
• During the day the land heats more
quickly than the water does.
• Warmer air rises over the land.
• Cooler air sinks over the water.
• A breeze moves from the water to land.
Land Breezes
• At night the land cools more quickly than the
water does.
• Warmer air rises over the water.
• Cooler air sinks over the land.
• A breeze moves from the land to water.
Review Question
•
•
•
•
•
How do land breezes happen?
Air cools faster over land and moves H to L
How does the Earth cause weather?
Tilt
High pressure areas are associated with
what kind of air?
• Cool air
Air Masses
(1)
• Air masses are large
bodies of air that
have the same
properties as the area
of the Earth’s surface
over which it forms
and moves.
• For example, deserts
produce hot dry air
masses.
Fronts
• The place where air
masses meet is called
a front.
• Weather is caused by
the way these air
masses interact.
Cold Fronts
• Incoming dense cold air pushes up warm air
• This forms a narrow band of violent storms
Warm Fronts
• Warm air slides over departing cool air.
• This forms feathery clouds.
Stationary Front
• A cool air mass and a warm air masses
meet and stop moving (neither one
advances).
• This causes a few days of rainy and windy
weather.
Review Questions
•
•
•
•
•
What cloud type can become tornadoes?
Cumulonimbus (same as thunderstorms)
Where do hurricanes form?
Over water
Describe how a cold front is represented
on a weather map?
• Blue line with triangles
Unit 5 Space
Rotation
Revolution
Tides
Review Questions
• What is the difference between rotation
and revolution?
• Rotation is spinning and revolution is
going around or orbiting
• What causes tides?
• Pull of the moon
• What side of the moon is lit during a
waxing crescent?
• Right
Review Questions
•
•
•
•
•
What happened to Pluto?
Pluto was declassified to a dwarf planet
Which planets are the gas giants?
Jupiter, Saturn, Uranus and Neptune
Which planets are the terrestrial
planets?
• Mercury, Venus, Earth and Mars
Unit 6 Watersheds
Review Question
• What states belong to the Chesapeake
Bay watershed?
• PA, VA, WV, DE, NY, MD and DC
• What are the 3 places water in VA will
eventually go?
• Chesapeake Bay, Gulf of Mexico and
North Carolina Sound
• What is the name of or local
watershed?
• Potomac
Review Questions
• What is the difference between point
and non-point pollution?
• Point source pollution is identifiable
• What are some causes of chemical
weathering?
• Acid rain
• What is an example of abiotic factor in
the environment?
• Temperature and water (nonliving)
