A systematic process used to gather knowledge and test ideas about the natural world. It involves making observations, asking questions, formulating hypotheses, conducting experiments, analyzing results, drawing conclusions, and communicating findings.

Information that can be measured numerically, typically expressed in numbers.

Information that describes qualities or characteristics, often using words or descriptions.

The variable that is intentionally changed or manipulated by the experimenter.

The variable that is measured or observed in an experiment to see how it changes in response to the independent variable.

The horizontal axis on a graph.

The vertical axis on a graph.

A summary of the results of an experiment, comparing the findings with the hypothesis and drawing conclusions about whether the hypothesis was supported or refuted.

The process of sharing research findings with others through various mediums, such as written reports, presentations, or publications.

A substance with a constant composition and properties, meaning it's made up of only one type of atom or molecule.

A pure substance that cannot be broken down into simpler substances by ordinary chemical means.

Matter composed of two or more different substances that are physically mixed together but not chemically combined.

The smallest unit of an element that retains the chemical properties of that element. It is made up of protons, neutrons, and electrons.

A group of two or more atoms held together by chemical bonds.

A substance formed when two or more elements are chemically combined in a fixed ratio by mass.

The process of using an electric current to break down a compound into its elements.

A substance that dissolves in a solvent to form a solution.

A substance that dissolves a solute to form a solution.

A mixture that has a uniform composition throughout. The components are evenly distributed.

A mixture that has a non-uniform composition. The components are not evenly distributed.

A characteristic of matter that can be observed or measured without changing the sample's composition.

A characteristic of matter that describes how a substance reacts with other substances or changes its composition.

A property that depends on the amount of matter present.

A property that is independent of the amount of matter present.

A change in the form or appearance of matter, but not its chemical composition.

A change in the chemical composition of matter, resulting in the formation of new substances.

A chemical reaction that releases energy into the surroundings, usually in the form of heat.

A chemical reaction that absorbs energy from the surroundings, usually in the form of heat.
