Term | Definition |
---|---|
Graphs | a diagram representing a system of connections or interrelations among two or more things by a number of distinctive dots, lines, bars, etc. |
Horizontal Axis | a reference axis, usually horizontal, of a graph or two- or three-dimensional Cartesian coordinate system along which the x-coordinate is measured. x-axis in Science |
Vertical Axis | Also called axis of ordinates. The axis, usually vertical, along which the ordinate is measured and from which the abscissa is measured |
Origin | The 0,0 point on a line graph, the point where the x-axis and y-axis cross on a graph. |
Coordinate | 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 peice 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 point yield a straight line |
Slope | The steepness of a line on a line graph, equal to its vertical chang divided by its horizontal change. |
Non-linear graph | A graph in which the data points do not fall in a straight line |
Science | The study of the natural world through observations and logical reasoning |
observing | the process of using one or more sense |
inferring | The process of making an inference an interpretation based on observations |
predicting | the process of forecasting what will happen in the future |
chemistry | the studies of properties of matterand how it changes |
physics | the study of matter, energy, motion, and forces and how they react. |
scientific inquiry | the ongoing process of discovery in science |
hypothesis | a possible explanation for a set of observations and an answer to a scientific question |
parameter | a factor that can be measured in an experiment |
manipulated variable | the one variable that a scientist changes |
responding variable | variables that change due to the manipulated variable |
