Study Cards for 6th Grade Science Final Exam


undefined, object
copy deck
Has volume and takes up space
The pull of gravity on an object
Why does ice float?
It is less dense than water.
Properties of Matter
Mass, Volume, Density
Mass divided by Volume
M / V
Metric unit for volume
Solid vs. Liquid
Which has the higher density?
The horizontal movement of air from an area of high pressure to an area of low pressure
Coriolis Effect
The way the Earth's rotation makes winds curve
Jet Stream
Bands of high speed winds located about 10 kilometers above Earth's surface
Ozone layer
Part of Earth's atmosphere that filters out the harmful rays of the sun
Part of the atmosphere on Earth where we live and where our weather occurs.
Carbon Dioxide
Causes heat to build up in the atmosphere.
Winds are named for the direction they are blowing to.
Gases in Earth's Atmosphere
Nitrogen 78% and Oxygen 21%
Causes of wind
Winds are caused by the sun heating the Earth differently around the world.
Movement of Air
Air tends to move from high pressure to low pressure areas.
Air flow near the water
During the day the air will flow from the sea to the land. At night, cooler air moves from the land to the sea.
Potential energy
The energy of position.
Example: Wound up spring or marble at the top of a ramp
Fossil Fuels
Coal, Oil, Natural Gas
The ability to do work.
Kinetic energy
The energy of motion.
Example: Moving car or boy running
Geothermal energy
Uses energy from inside the Earth.
Thermal energy
Heat energy which could be collected on solar panels.
Light energy
A photovoltaic cell (used on calculators)uses this type of energy from the sun to power the source.
Chesapeake Bay
Largest ESTUARY in the United States. 24,000 sq miles of watershed. Habitat to 3,600 species
Polar Ice Caps
Located at the 'top' and 'bottom' of the Earth at the poles
Phases of the moon
New moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent.
Rotation vs Revolution
Rotation - spinning around an axis - Earth does this every 24 hours. Revolution - revolving around an object - Earth revolves around the Sun every 365 days.
Safety symbols
Eye safety - goggles
Electrical safety - plug
Poison - skull and crossbones
Beginning energy source in all food chains (and webs)
Metric base units (SI)
Volume - liter
Mass - gram
Length - meter
Temperature - Celcius
Mass - triple beam balance
Volume - graduated cylinder
Length - metric ruler/meter stick
Temperature - thermometer
Solar cells
Turn sunlight into electricity
EARTH's movement
Rotation - days
Tilt - seasons
Revolution - years
Measuring weather (instruments)
Temperature - thermometer
Wind - anemometer
Air pressure - barometer
Air movements - satellites
Psychrometer - humidity
Cirrus - wispy
Stratus - layered
Cumulus - puffy
Nimbus - rain
Water cycle
Precipitation - rain, snow, sleet (liquid)
Condensation - dew, clouds (gas to liquid)
Evaporation - rising into air (liquid to gas)
Transpiration - water into atmosphere from leaves of plants (liq to gas)
Space exploration
Manned ships to the moon.
Unmanned ships to Venus, Mars, Jupiter
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
Solar System
Sun, planets, asteroids
Electromagnetic spectrum
Different frequencies on this spectrum tell scientists many things about this universe
General kinds of energy (2)
Kinetic and potential
Areas of positive and negative charges build up in storm clouds
Major problems in the Chesapeake Bay
Pollution - sediment, nutrient, air, toxic
Sprawl - overpopulation of people and construction
Renewable vs Nonrenewable energy sources
Renewable - solar, wind, geothermal,biomass, hydro, ocean
Nonrenewable - oil, natural gas, coal, uranium
Causes of endangerment or extinction
HABITAT DESTRUCTION, overfishing, poaching
A large number of different species living in one area
Earth's water
97% salt, 3% fresh
Fresh water
Ice 76%
Groundwater 23%
Lakes and rivers 0.34%
Water vapor 0.037%
wet land - swamps, marshes, bogs (soaks up water)
Watershed - LAND where the water runs off into a large body of water
Permeable vs Impermeable
Permeable - water can pass through (dirt, grass)
Impermeable - water runs off (pavement, roofs)
Causes major problems in polluting the waterways
Best Management Practices - things you can do to help keep the water clean
A semi enclosed body of water where the fresh water meets the salt water and becomes brackish
