The study of the natural world.
Using one or more senses to gather information.
The process of making an inference; an interpretation based on observation and prior knowledge.
Making a forecast of what will happen in the future based on past experience or evidence.
The study of matter, energy and the changes they undergo.
The study of the properties of matter and how matter changes.
The study of matter, energy, motion, forces, and how they interact.
The ongoing process of discovering science.
A possible answer to a science question or possible explanation for a set of observations.
A factor that can be measured in an experiment.
The variable parameter that a scientist changes during an experiment.
The variable parameter that changes as a result of changes to the manipulated or independent variable in an experiment.
An experiment in which only one parameter is manipulated at a time.
The facts, figures and other evidence gathered through observations.
The process of sharing ideas and conclusions with others through writing or speaking.
A well-tested explanation for a wide range of observations or experimental results (atomic theory states that all substances are composed of tiny particles called atoms).
A statement that describes what scientists expect to happen every time under a particular set of conditions (law of gravity).
An expanded metric system, International Systems of Units, which allows scientists to compare data using a standard system of measurement.
SI unit of length.
A measure of the force of gravity on an object.
A measure of how much matter is in an object.
SI unit of mass.
The amount of space matter occupies.
SI unit of volume.
The curved upper surface of a liquid in a column of liquid.
The ratio of the mass of a substance to its volume.
kilogram per cubic meter
SI unit of density.
SI unit of time.
SI unit of temperature.
The temperature at which no more energy can be removed from matter.
An approximation of a number based on reasonable assumptions.
How close a measurement is to the true or actual value.
How close of a group of measurements are to each other.
A ll the digits in a measurement that have measured exactly, plus one digit whose value has been estimated.
A measure of the exactness of a measurement.
A picture of information from a data table; shows the relationship between variables.
line of best fit
A smooth line that reflects the general pattern in a graph.
A line graph in which the data points yield a straight line.
The steepness of a line on a graph, equal to its vertical change divided by its horizontal change. Rise/Run
A line graph in which the data points do not fall along a straight line.
