• Occurs when cold air mass moves warm air mass upward Memory Pictograph Facts/Examples/NonExample • Brings cold and unstable weather • Can be fast or slow • Can form dangerous clouds quickly and lead to severe weather • EX: cumulonimbus clouds (tallest and possible tornado producers) • NONEX: warm front – rain likely and less severe community Definition • Group of different populations living in the same place Memory Pictograph Facts/Examples/NonExample • Groups of organisms affect each other in the community • Creates a unique area • EX: forest community, pond community, meadow community, coral reef community • NONEX: population refers to just one species in a community competition Definition Facts/Examples/NonExample • Interaction between 2 organisms over basic resources such as food, water, shelter, mates • The more adaptations an organisms has to its environment, the less it needs to compete • Some animals change their habits to have less competition • EX: invasive species outcompeting native species, deer feeding at different times or on different plants • NONEX: mutualism Memory Pictograph compound Definition Facts/Examples/NonExample • Pure substance made up of 2 or more different elements that are bonded together • Have chemical and physical properties not like the original elements • Always has a chemical formula • EX: salt (NaCl), water (H2O), carbon dioxide (CO2) • NONEX: elements are made of just one type of atom, mixtures are made of different materials next to each other BUT NOT BONDED TOGETHER Memory Pictograph conclusion Definition • Explains whether the hypothesis of an experiment was supported by the results of the experiment Memory Pictograph Facts/Examples/NonExample • Summary that re-checks the hypothesis • Part of the scientific method • Examines the data and results of an experiment • EX: see memory pictograph • NONEX: hypothesis has to be tested/ conclusion states whether hypothesis is supported by the results of the

in the water cycle • Physical change • EX: cold glass on a hot humid day forms condensation, fog, clouds, dew • NONEX: evaporation is the opposite of condensation conductor Definition • Material that allows heat and electricity to pass through Memory Pictograph Facts/Examples/NonExample • Molecules either vibrate (heat) or pass along electrons (electricity) • Metals are the best conductors • Nonmetals are usually insulators, not conductors • EX: copper, aluminum, iron, steel • NONEX: rubber, plastic, wood consumer Definition • Organism that cannot make its own food and must get food by consuming other organisms Memory Pictograph Facts/Examples/NonExample • Needs to obtain energy by eating other organisms • Can eat producers (plants) or other consumers • EX: humans, herbivores, carnivores, omnivores • NONEX: producers make their own food through photosysthesis control Definition • Part of an experiment that is kept the same so it can be used as a comparison to the other data Memory Pictograph Facts/Examples/NonExample • Helps check results of experiment • Makes experiments more accurate • EX: experiment comparing fertilizers, one trial has NO fertilizer • NONEX: constants in an experiment keep all conditions similar, control leaves out the manipulated variable (independent variable) cytoplasm Definition • Thick fluid contained in the cell membrane of all cells Memory Pictograph Facts/Examples/NonExample • Helps hold or contain the insides of a cell • Cell jelly/ gel • Allows materials to move about inside cell • Mostly water • EX: found in all types of cells • NONEX: cell organelles are supported by cytoplasm data (datum) Definition • Information gathered and organized during an experiment Memory Pictograph Facts/Examples/NonExample • Graphs and charts • Shows observations and evidence • Good data comes form fair experiments and good variables • EX: Data chart for experiment in class • NONEX: conclusions and analysis occur after collecting data decomposer Definition • Organism that obtains food by breaking down dead organisms Memory Pictograph Facts/Examples/NonExample • Uses dead organisms as nutrients • Critical for healthy ecosystem • Helps rid nature of dead organisms • Types of consumer • EX: bacteria, fungus • NONEX: scavengers arrive before too much decomposition takes place density Definition • Ratio of mass to volume Memory Pictograph Facts/Examples/NonExample • Density = mass / volume • Depends on how • How tightly packed are the molecules in a given amount of space? • Feathers ----low density • Gold ---------high density • Water has a density of 1 • > 1 sink in water • < 1 float in water digestive system Definition • Organ system that breaks down food into a form that the body can absorb/ use Memory Pictograph Facts/Examples/NonExample • Uses both physical and chemical changes in the process • Broken down materials move from the small intestine into the blood stream • Circulatory system moves food and nutrients through the blood to the cells direct rays Definition • Sunlight that reaches the Earth with more intensity Memory Pictograph Facts/Examples/NonExample • Strikes at a direct angle and more energy is hitting the surface • Always occurring near the equator • Summer has more direct rays than winter • EX: tropical rain forests receive direct rays all year • NONEX: polar areas never receive direct rays dominant traits Definition • Inherited traits that show up more often in a population Memory Pictograph Facts/Examples/NonExample • Traits that occur with greater frequency • Research of Gregor Mendel and pea plants • Geneticists study dominant and recessive traits • EX: brown hair, brown eyes, widow’s peak, etc… • NONEX: blue eyes, red hair are recessive traits for the general population echo Definition • Sound waves bouncing back from hitting a hard surface Memory Pictograph Facts/Examples/NonExample • Sound energy is a mechanical wave that can be absorbed or reflected by the objects it hits • Used by bats and dolphins to locate prey or predators • EX: cave, gym, shower, empty room • NONEX: room covered with carpeting on floors and walls echolocation Definition • Method of navigation in which sound waves are bounced off objects to determine distance and location Memory Pictograph Facts/Examples/NonExample • Used by bats and dolphins and other animals • Helps locate prey • Humans borrowed idea for radar and sonar • EX: sonar bounces sound waves at sea • NONEX: radar bounces EM waves not sound waves ecosystem Definition • All the living and nonliving things in a community Memory Pictograph Facts/Examples/NonExample • Make up a special location where organisms and resources interact • Air, water, soil, are nonliving but still important to ecosystem working properly • EX: forest ecosystem, pond ecosystem, estuary ecosystem • NONEX: a single population of one organisms egg cell (ovary) • Definition Facts/Examples/NonExample Cell produced by the female reproductive system – must combine with sperm cell to become fertilized • Organisms that reproduce through sexual reproduction must begin as an egg cell • Can grow into seeds or infants • Must be fertilized in order to grow • EX: chicken egg cell – very large cell • NONEX: organisms that reproduce asexually do not require egg cells to reproduce Memory Pictograph electromagnet Definition • Powerful magnet produced by coiling wire around iron and running electricity through Memory Pictograph Facts/Examples/NonExample • Attracts certain metals only – iron, steel, nickel • Moving electrons make the magnet more powerful • EX: lifts up scrap cars and even small electromagnets can lift heavier weights • NONEX: regular magnets with no added wires and electricity element Definition Facts/Examples/NonExample • A pure substance that consists of only one type of atom with unique properties Memory Pictograph • Found on periodic table • Cannot be broken down further • Atomic number is determined by number of protons in the nucleus • Neutrons are also in the nucleus • Electrons move in different energy shells around the nucleus • EX: each of the types of atoms listed on Periodic Table • NONEX: compounds, mixtures element Definition Facts/Examples/NonExample • A pure substance that consists of only one type of atom with unique properties Memory Pictograph • Found on periodic table • Cannot be broken down further • Atomic number is determined by number of protons in the nucleus • Neutrons are also in the nucleus • Electrons move in different energy shells around the nucleus • EX: each of the types of atoms listed on Periodic Table • NONEX: compounds, mixtures elevation Definition • Height above sea level Memory Pictograph Facts/Examples/NonExample • Can be above or below sea level • Topographic maps show elevation • EX: Detroit area is about 600 feet above sea level, so its elevation is 600 feet • NONEX: latitude or longitude show location on the globe, but not elevation above sea level embryo Definition • Very early stage in the development of an organism Memory Pictograph Facts/Examples/NonExample • An embryo will develop form a fertilized egg • Stages of the embryo are related to stages of evolution (looks different at different stages) • Will develop into a baby organism • EX: human embryo, chicken embryo • NONEX: does not occur in asexual reproduction, requires egg and sperm cells erosion Definition • Process in which soil and rock particles are carried away by wind, moving water or gravity Memory Pictograph Facts/Examples/NonExample • Natural force that causes rocks to lose particles • Changes the appearance of rocks • EX: Sphinx and tombstones affected by wind and acid rain • NONEX: deposition is the opposite action and sediments build up in areas where wind or water oor ice slow down evaporation Definition • Physical change of state (phase change) from a liquid to a gas state Memory Pictograph Facts/Examples/NonExample • 1st step in the water cycle • Sun’s energy is what causes molecules of water to move faster and evaporate • Other liquids also evaporate when energy is added (heat) • EX: water, alcohol, gasoline all evaporate into the air • EX: boiling water is rapid evaporation • NONEX: condensation is the opposite of evaporation evidence Definition • Any tested observation or experimental data that supports a hypothesis Memory Pictograph Facts/Examples/NonExample • Data must support the hypothesis in order to be evidence that the hypothesis is correct • Allows scientists to know whether they are on the right track or need to “go back to the drawing board” • EX: gas and bubbles in an experiment show a chemical change • NONEX: guessing with no facts supporting the guess evolution Definition Facts/Examples/NonExample • Scientific Theory that explains changes in organisms over long periods of time • Successful adaptations increase the chances of surviving and reproducing • Poor adaptations make it more difficult for an organisms to survive and reproduce • EX: fast running animals escape predators and survive • NONEX: giraffes didn’t grow longer necks in one generation…but the taller giraffes survived better and reproduced offspring like themselves Memory Pictograph 8th Grade Science Vocabulary Terms (140 terms for Frayer Model) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. absorb acquired
