Ch.1 definitions

TermDefinition
Science the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
observing notice or perceive (something) and register it as being significant.
Inferring deduce or conclude (information) from evidence and reasoning rather than from explicit statements.
Predicting say or estimate that (a specified thing) will happen in the future or will be a consequence of something.
Chemistry the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
Physics activities through which students develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world."
Hypothesis a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Parameter a numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation.
Manipulated handle or control (a tool, mechanism, etc.), typically in a skillful manner.
Controlled Experiment is a test where the person conducting the test only changes one variable at a time in order to isolate the results. An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation is an example of a contr
Data facts and statistics collected together for reference or analysis.
Model a three-dimensional representation of a person or thing or of a proposed structure, typically on a smaller scale than the original
Scientific theory a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.
Responding Variable The independent (or manipulated) variable is something that the experimenter purposely changes or varies over the course of the investigation. The dependent (or responding) variable is the one that is observed and likely changes in response to the indepen
SI a system of physical units ( SI Units ) based on the meter, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten.
Weight a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
Mass a coherent, typically large body of matter with no definite shape. "a mass of curly hair"
Volume volume the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
Meniscus the curved upper surface of a liquid in a tube.
Scientific Inquiry refers to the activities through which students develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world."
Estimate roughly calculate or judge the value, number, quantity, or extent of.
Accuracy the quality or state of being correct or precise.
Reproducibility he ability of an entire experiment or study to be duplicated, either by the same researcher or by someone else working independently. Reproducing an experiment is called replicating it.
Significant Figures ach of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit.
Precision The quality, condition, or fact of being exact and accurate.
Graph a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.
Horizontal Axis The horizontal (H), or nearest horizontal, plane on a two- or three-dimensional grid, chart, or graph in a Cartesian coordinate system. See also Cartesian coordinates, y-axis, and z-axis.
Vertical Axis (in a plane Cartesian coordinate system) the axis, usually vertical, along which the ordinate is measured and from which the abscissa is measured. (in a three-dimensional Cartesian coordinate system) the axis along which values of y are measured and at wh
Origin the point or place where something begins, arises, or is derived
Coordinate bring the different elements of (a complex activity or organization) into a relationship that will ensure efficiency or harmony.
Data Point an identifiable element in a data set.
Line of Best Fit A straight line drawn through the center of a group of data points plotted on a scatter plot. Scatter plots depict the results
Linear Graph a series of points, discrete or continuous, as in forming a curve or surface, each of which represents a value of a given function. Also called linear graph. a network of lines connecting points.
Slope (of a liquid) spill or flow over the edge of a container, typically as a result of careless handling.
Nonlinear Graph Meaning there is no exponent showing with the variable. That also means they are linear functions. Check the non-linear functions given on the previous page and see that they are not a straight line when graphed, have no constant difference, and have expo
