The study of matter and energy and how they interact

The different ways scientists study the natural world

A possible answer to a scientific question or explanation for a set of observations

Factors that can change in an experiment

Manipulated Variable or INDEPENDENT

The variable that is changed in an experiment

Responding Variable or DEPENDENT

The variable that is expected to change because of the manipulated variable

Controlled Experiment

An investigation in which all variables except one remain the same

The facts, figures, and other evidence gathered through observations

Sharing ideas and conclusions with others through writing and speaking (sharing the process you used in your inquiry)

A statement that describes what scientists expect to happen every time under a particular set of conditions

A well-tested explanation for a wide range of observations or experimental results

An approximation of a number based on reasonable assumptions

How close a measurement is to the true or accepted value

How close a group of measurements are to each other

The number that appears the most often in a list of numbers

To the digits in a measurement (it is much more than just that, so please go look up how to find significant figures)

Anything that has mass and takes up space

A single kind of matter that is pure, meaning it always has a specific makeup (composition) and a specific set of properties

A characteristic of a pure substance that can be observed without changing it into another substance

A characteristic of a pure substance that describes its ability to change into different substances

A pure substance that cannot be broken down into any other substances by chemical or physical means (simplest substances)

The basic particle from which all elements are made

A force of attraction between two atoms

A neutral particle made of two or more atoms joined by covalent bonds

A pure substance made of two or more elements chemically combined in a set ratio

Shows the elements in the compound and the ratio of atoms

Made of two or more substances (elements, compounds, or both) that are together in the same place but are not chemically combined (can be separated by physical means)

Heterogeneous Mixture

You can see the different parts

The substances are so evenly mixed, that you can't see the different parts

A well-mixed mixture containing a solvent and at least one solute that has the same properties throughout

A measure of the force of gravity on an object

The measurement of the amount of matter in the object

International System of Units (SI Units)

A system that scientists use to measure the properties of matter

The amount of space that matter occupies

The ratio of the mass of a substance to its volume

Any change that alters the form or appearance of matter but does not make any substance in the matter into a different substance

A change in matter that produces one or more new substances (produces new substances with properties different from those of the original substance)

Law of Conservation of Mass

The fact that matter is not created or destroyed in any chemical or physical change

The ability to do work or cause change

A measure of the average energy of random motion of particles of matter

The total potential and kinetic energy in all of the particles of an object

A change in which energy is taken in (absorbed)
