Terms in this set (45)
Constant
Staying the same
Ex. The temperature was kept constant in the experiment.
Procedure
The method of doing some action, especially the sequence of steps to be followed.
Ex. Follow the procedure explained in the laboratory manual.
Significant
Having importance or meaning.
Ex. A significant number of people voted against the bill.
Science
The study of 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 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.
Hypothesis
A possible explanation for a set of observations or answer to a scientific question.
Parameter
A factor that can be measured in an experiment.
Manipulated Variable
The one variable parameter that a scientist changes during an experiment.
Responding Variable
The variable parameter that changes as a result of changes to the manipulated, or independent, variable in an experiment.
Controlled Experiment
An experiment in which only one parameter 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
A representation of an object or process.
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.
SI
International System of Units; a version of the metric system used by scientists all over the world.
Weight
A measure of the force of gravity on an object.
Mass
A measure of how much matter is in an object.
Volume
The amount of space that matter occupies.
Meniscus
The curved upper surface of a liquid in a column of liquid.
Density
The ratio of the mass of a substance to its volume.
Celsius Scale
The temperature scale on which water freezes at 0 degrees and boils at 100 degrees.
Kelvin Scale
The temperature scale on which zero is the temperature at which no more energy can be removed from matter. On this scale, water freezes at 273 degrees and boils at 373 degrees.
Absolute Zero
The temperature at which no more energy can be removed from matter.
Estimate
An approximation of a number based on reasonable assumptions.
Accuracy
How close a measurement is to the true or accepted value.
Reproducibility
How close a group of measurements are to each other.
Significant Figures
All the digits in a measurement that have been measured exactly, plus one digit whose value has been estimated.
Precision
A measure of the exactness of measurement.
Graph
A picture of information from a data table; shows the relationship between variables.
Horizontal Axis
The x-axis. A line that runs left to right along the bottom of a graph on which the manipulated variable (or independent variable) is located.
Vertical Axis
The y-axis. A line that runs up and down along the side of a graph, on which the responding variable (or dependent 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 the position of a point on a graph. Written as (x,y).
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 of a graph.
Linear Graph
A line graph in which that 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 (rise over run).
Nonlinear
A line graph in which the data points do not fall along a straight line.
Graph
A picture of information from a data table; shows the relationship between variables.
