1. Sketch the diagram

2. Copy the question

3. Choose your answer

4. Explain your answer

conclusionDefinition

• 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

condensationDefinition

• 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

conductorDefinition

• 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

consumerDefinition

• 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

controlDefinition

• 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

cytoplasmDefinition

• 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

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

decomposerDefinition

• 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
