Definition stack


science a way of learning about the natural world through observations and logical reasoning
observing the process of using one or more of your senses to gather information
inferring the process of making an inference, an interpretation based on observations and prior knowledge
predicting the process of forecasting what will happen in the future based on past experience or evidence
chemistry the study of the properties of matter and how matter changes
physics the study of matter,energy,motion and forces and how they interact
scientific inquiry 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
hypothesis a possible explanation for a set of observations or answer to a scientific question must be testable
parameter a factor that can be measured in an experiment
manipulated variable the one factor that a scientist changes during an experiment; also called independent variable
responding variable the factor that changes as a result of changes to the manipulated,or independent, variable in an experiment; also called dependent variable
controlled experiment an experiment in which only one variable is manipulated at a time
data Facts,figures, and other evidence gathered through observations
communicating the process of sharing ideas with others through writing and speaking
model physical,mental,visual and other representations of an idea to help people understand a concept that they cannot observe directly
scientific theory a well-tested explanation for a wide range of observations or experimental results
scientific law a statement that describes what scientists expect to happen every time under a particular set of conditions
graph a picture of information from a data table shows the relationship between variables
horizontal axis a line that runs left to right along the bottom of a graph on which the manipulated variable (or independent variable) is labeled
vertical axis a line that runs up and down along the side of a graph, on which the responding variable ( or independent variable) is labeled
origin the (0,0) point on a line graph where the x-axis and y-axis cross on a graph
coordinate a pair of numbers used to determine a position of a point on a graph
data point a point on a graph showing the location of a piece of data
line of best fit a smooth line that reflects the general pattern in a graph
linear graph a line graph in which the data points yield a straight line
slope the steepness of a line on a graph, equal to its vertical change divided by its horizontal change
nonlinear graph a line graph in which the data points do not fall along a straight line
Qualitative data data that uses descriptions instead of numbers
Quantitative data data collected by measuring; uses numbers
