Term	Definition
Science	a way of learning about the natural world through observations and logical reasoning; leads to a body of knowledge.
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 properties of matter and how matter changes.
Physics	the study of matter, energy, motion, and forces, and how they interact.
scientific inquiry	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.
parameters	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 variable, or independent variable, variable in an expression; also called dependant 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	what scientists expect to happen every time under a particular set of conditions.
graph	a picture of information from a date table: shows the relationship between variables.
horizontal axis	(x-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	(y-axis). a lien that runs up and down along the side of a graph, on which the responding variable (or dependant variable) is labeled.
origin	the (0, 0) point on a line graph, where the x-axis and y-axis cross line on a graph.
coordinant	a pair of numbers used to determine the 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 yields a straight line.
slope	the steepness of a line on a graph, equal to its vertical change divided by its horizontal change.
non linear graph	a line in which the data points don't fall along a straight line.
qualitative data	data that cant be measured and doesn't involve numbers.
quantitative data	data that involves numbers and / or can be measured.
