notes, and reading passages.

terrestrial: anything that relates to land or planet earth abiotic: all of the nonliving parts of an ecosystem desert: a biome that gets little precipitation and has very little vegetation biotic: all of the living parts of an ecosystem tundra: extremely cold climate located near the North and South Poles and on the tops of mountains; receives very little precipitation and has no trees biome: a major ecological community such as grassland, tropical rain forest, or desert taiga: a large naturally occurring area of land with largely evergreen forest vegetation found in northern sections of the Northern Hemisphere ecosystem: all the living and nonliving things in an area that interract with each other deciduous forest: a forest containing trees that lose their leaves each year tropical rainforest: a forest that is humid and rainy for much of a year grasslands: an area of land covered mostly with grass with few bushes or trees

STUDY GUIDE

thermal energy: The motion of atoms and molecules that creates a change in temperature. temperature: the measure of how warm something is transfer: the movement of something from one place to another. Heat always moves from something WARMER to something COOLER. conduction: the passing of heat through a material while the material itself stays in place. Two things must be touching each other for conduction to occur! convection: the flow of heat through a liquid or a gas, causing hot parts to rise and cooler parts to sink.

convection currents: warm liquids rising or gases rising radiation: The transfer of heat through electromagnetic rays

Insulator: a material that reduces or prevents heat from passing through. The best insulators are wood and plastic. Conductor: a material that allows heat to pass through it while the material itself stays in place. The best conductors are metals. electromagnetic waves: a wave that travels at the speed of light through space due to radiation. *Objects expand as they are heated because the molecules get EXCITED! Objects contract as they are cooled.

STUDY GUIDE

matter: anything that has mass and takes up space. EVERYTHING is made of matter even air! mass:: the amount of matter in an object (mass never changes, even on the moon!) conservation of mass: the mass of an object will stay the same, even if it is broken into smaller pieces or if it warmed up

*THINK ABOUT IT: If a blown up balloon gets warmed up and begins to expand

even more, has the mass actually changed?* weight: the force of gravity on an object (will change on the moon!) volume: the amount of space an object or substance takes up density: a measure of how many particles are packed together into a certain amount of space physical change: a change in matter that DOES NOT affect its chemical composition (NO new substance is formed!!) chemical change: a process that changes substances into NEW substances. Remember, after a chemical change occurs, the substance can NEVER be changed back into what it started as! solution: a combination of substances that cannot be easily separated mixture: a combination of substances that can be physically separated FIFTH GRADE SCIENCE EOG

STUDY GUIDE

force: a push or a pull that is applied to an object friction: a force that opposes the motion of a body across a surface or through a gas or liquid

gravity: a force that exists between any two objects that have mass inertia:

speed: distance traveled per unit of time (Speed = Distance ÷ Time)

velocity: the speed of something in a given direction acceleration: any change in speed OR direction potential energy: stored energy in an object when it is not moving. kinetic energy: energy of an object in motion balanced forces: when two equal forces are applied to an object in opposite directions

unbalanced forces: when two forces that are not equal are applied to an object causing the object to move FIFTH GRADE SCIENCE EOG

stay in motion until a force acts upon it. 3. For every action, there is an equal and opposite reaction. FIFTH GRADE SCIENCE EOG

STUDY GUIDE

water cycle: the air, changing from liquid to gas to liquid. evaporation: the process in which a liquid changes into a gas condensation: the process in which a gas changes into a liquid the water must COOL before it can become a cloud!precipitation: any form of water particles that fall to the earth (rain, snow, sleet, hail) transpiration: the process of plants absorbing water through their roots, the water moving up to the leaves, and then evaporating vapor: water in its gaseous state runoff: water that flows downhill to rivers, streams, or lakes cirrus cloud: a high altitude cloud with a featherlike shape, made of ice crystals cumulus cloud: a puffy cloud that appears to rise up from a flat bottom stratus cloud: a cloud that forms in a blanket-like layer cumulonimbus cloud: a cloud that develops upward and brings thunderstorms humidity: the amount of water vapor in the air fog: a cloud at ground level

FIFTH GRADE SCIENCE EOG

STUDY GUIDE

trend: weather patterns over a period of time satellites: devices that are launched into space and used to collect data about weather air pressure: the weight of air pressing down on earth. *Air pressure has the greatest effect on wind speed! In a low pressure system, wind speeds will be higher. In a high pressure system, winds will be

lower*

jet stream: strong winds in a narrow stream high in the atmosphere (like a river in the sky) COLD air is found above the Jet Stream. WARM air is found BELOW the Jet Stream. Therefore, the Jet Stream is typically found between a warm air mass and a cold air mass. If the Jet Stream dips below NC, we get COLD air from the north! If it bends above NC, we get the WARM air from the south!gulf stream: a stream of water in the Atlantic ocean that carries warm water north from the south of Florida. The Gulf Stream is what keeps our winters nice and mild along the coast!forecast: a prediction, using data, about what the weather will be for a period of time in the future. mountain breeze: a cool night wind that blows down a mountain slope and replaces the warmer air in the valley sea breeze: wind that blows from sea to land land breeze: wind that blows from land to sea *Winds at the beach change direction between day and night because of

changes in TEMPERATURE!*

prevailing westerlies: the winds from the west that are most responsible for weather in North Carolina. They are named by where the wind COMES from!

front: a boundary between air masses with different temperatures

high pressure system: a mass of cool, dry air that brings fair weather including sunny skies and light winds. Remember: HAPPY high! low pressure system: a mass warm, moist air that usually brings stormy weather and strong winds. Remember: LOWSY low! El Nino: the United States (the Pacific Ocean!) El Nino can cause drought along the west coast and flooding in South America. La Nina: the United States (the Pacific Ocean!) Warm Front
