| Question | Answer |
|---|---|
| bias | statistical sampling or testing error caused by systematically favoring some outcomes over others |
| conclusion | a summation of what is learned from an experiment |
| constant | a quantity that, under stated conditions, does not vary with changes in the environment |
| control | the group treated normal to which the experimental group is compared |
| data | recorded observations from experiments |
| data table | a framework for organizing data measured or recorded from an experiment |
| dependent variable | the factor measured or observed to obtain results (sometimes referred to as the responding variable), usually graphed on the y-axis |
| direct relationship | when two or more variables are related and change together |
| evidence | facts or signs that help one to form an opinion based on observations |
| experimental group | exposed to all conditions of the experiment except the experimental variable |
| procedure | detailed, step-by-step directions for conducting a science experiment which allow duplication |
| hypothesis | a testable explanation for an observation or scientific problem |
| independent variable | the one factor in an experiment that is determined and changed by the experimenter (sometimes referred to as the manipulated variable), usually graphed on the x-axis |
| inverse relationship | relationship of variables: when one increases, the other decreases |
| mass | a measure of the amount of matter in an object |
| qualitative | involving quality or kind, recorded with a characteristic that cannot be expressed in numbers |
| quantitative | the measured amount, recorded with a number |
| result | outcome, usually of an experiment |
| scientific evidence | data found using a scientific process |
| temperature | average kinetic energy (movement) of molecules in an object |
| theory | a well-tested explanation of some aspect of the natural world |
| thermometer | instrument used to measure temperature (average kinetic movement of molecules in an object) |
| variable | factor that can change in an experiment |
| validity | the extent to which a test measures what it claims to measure |
| interpret | to determine the patterns and trends from data/information |
| Sample Size | number of individuals in the experimental and control groups |
| Property | special quality or feature of a substance or an organism that may be used for identification |
| Mean | one of the measures of a central tendency; the sum of numbers in a set divided by the number of pieces of data |
| Balance | an instrument for weighing or equality between the totals of both sides |
| Spring Scale | tool used to measure weight or force |
| Toxic | having the affect of poison |
| Corrosive | any substance that oxidizes metal or flesh |
| Radioactive | substance with an untestable nucleus that loses energy by emitting particles or electromagnetic waves |
