2. conclusion Definition Explains whether the hypothesis of an experiment was supported by the results of the experiment 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 experiment Memory Pictograph

3. condensation Definition Physical change in matter from a gas to a liquid state Facts/Examples/NonExample Caused by cooling of the temperature of the gas Second step 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 Memory Pictographs

4. conductor Definition Material that allows heat and electricity to pass through 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 Memory Pictograph

5. consumer Definition Organism that cannont make its own food and must get food by consuming other organisms 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 Memory Pictograph

6. control Definition Part of an experiment that is kept the same so it can be used as a comparison to the other data 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) Memory Pictograph

7. cytoplasm Definition Thick fluid contained in the cell membrane of all cells 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 Memory Pictograph

8. data (datum) Definition Information gathered and organized during an experiment 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 Memory Pictograph

9. decomposer Definition Organism that obtains food by breaking down dead organisms 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 Memory Pictograph
