A way of learning about the natural world through observations and logical reasoning; leads to a body of knowledge.
The process of using one or more of your senses to gather information.
An observation that deals with a number or amount.
An observation that deals with characteristics that cannot be expressed in numbers.
The process of making an inference, an interpretation based on observations and prior knowledge.
The process of forecasting what will happen in the future based on past experience or evidence.
The process of grouping together items that are alike in some way.
Comparing observations and data to reach a conclusion about them.
The process of creating representations of complex objects or processes.
The study of principles about what is right and wrong, fair and unfair.
A mistake in the design of an experiment
The ongoing process of discovery in science, the diverse ways in which scientists study the natural world and propose explanations based on evidence they gather.
A possible explanations for a set of observations or answer to a scientific questions; must be testable.
A factor that can change in an experiment.
The one factor that a scientist changes during an experiment; also called manipulated variable.
The factor that changes as a result of changes to the manipulated or independent variable in an experiment; also called responding variable.
An experiment in which only one variable is manipulated at a time.
Facts, figures, and other evidence gathered through observations.
A well-tested explanation for a wide range of observations or experimental results.
A statement that describes what scientists expect to happen every time under a particular set of conditions.
when a sample cannot be counted exactly; an approximation of a number based on reasonable assumptions
how close the measurement is to the true or accepted value
how close a group of measurements are to each other
used to communicated how precise measurements are. Include all digits measured exactly, plus one estimated digit
the numerical average of a set of data
the middle number in an ordered set of data
the number that appears the most in a set of numbers
the difference between the highest value and the lowest value in a set of numbers
human or equipment error producing data that does not fit with the rest of the data set
the percent difference between the known value of a substance and its measured value during an experiment
a "picture" of data
a line graph in which the data yields a straight line
a graph in which the data points do not fall along a straight line
when one point on a graph is clearly not part of the trend, and is considered anomalous data
a repetition on an experiment
an attempt by a different group of scientists to conduct the same experiment
a generalization that makes sense of observations using logical reasoning (when a controlled experiment cannot be set up)
