| independent variable | The one factor that a scientist changes during an experiment |
| dependent variable | The factor that changes as a result of of changes to the manipulated variable in an experiment |

| personal bias | An outlook influenced by a person's likes and dislikes |
| cultural bias | An outlook influenced by the beliefs, social forms and traits of a group |
| experimental bias | A mistake in the design of an experiment that makes a particular result more likely |
| objective | Act of decision making or drawing conclusions based on available evidence |
| subjective | The influence of personal feelings on a decision or conclusion |
| deductive reasoning | A way to explain things by starting with a general idea and then applying the idea to a specific observation |
| inductive reasoning | Using specific observations to make generalizations |
| SI international system of units | A system of measurements of mass, length and time (used world-wide) |
| metric system | A system of measurement based on the number 10 |
| mass | a measure of the amount of material in an object |
| weight | A measure of the effect of gravity on an object |
| volume | The amount of space that matter occupies |
| meniscus | The curved upper surface of a liquid in a column of liquid |
| density | The mesurement of how much mass of a substance is contained in a given amount of volume |
| accuracy | How close a measurment is to the true or accepted value. |
| precision | How close a group of measurement are to eachother. |
| significant figures | All the digits in a measurement that have been measured exactly. (plus one digit whose value is estimated) |
| percent error | A caculation used to show how accurate or close to the true value, an experimental value really is. |
| mean | The numerical average of a set of data. |
| median | The middle number in a set of data. |
| mode | The number that appears most often in a list of numbers. |
| range | The difference between the greatest value and the least value in a set of data. |
| anamolous data | Data that do not fit with the rest of the of data set . |

| linear graph | Data points yeild a straight line. |
| non-linear graph | Data point that do not fall on a straight line. |
| scientific inquiry | The ongoing process of discovery in science. |
| hypothesis | A possible explantion for a set of observations or answer to a scientific question. Must be testable. |
| controlled experiment | An experiment in which only one variable is manipulated at a time. |
| data | Facts. figures and other evidence gathered through observations. |
| repeated trials | A repetition of an expirement to gather additional data and determine wether the experimant`s results support the hypothesis. |
| replication | An attempt to repeat a scientist,s experiment by a different scientist a group of scientists. |
| quantitative observation | an observation that deals with a number or amount |
| qualitative observation | An observation that deals with characteristics that cannot be expressed with numbers |
| inferring | an interpretation based on observations and prior knowledge |
| estimate | An approximation of a number based on reasonable assumptions |
| outlier | An abnormal or irregular data point that is clearly not part of the trend |
| scientific explanation | A generalization that makes sense of observations by using logical reasoning. |
