Physical Science

Control

The standard used for comparison of test results in an experiment. Control. In science, a control is something kept the same in an experiment to see how other variables change in comparison.

Data

Information gathered through observation. Data. In Science, data is the collected facts and measurements from experiments or observations used to understand the world.

Density

An objects mass per unit volume. Density. Density is how much stuff is packed into a certain amount of space.

Experiment

Testing a hypothesis by collecting data in controlled conditions. Experiment. An experiment is a test scientists do to learn more about how something works.

Hypothesis

A possible explanation or answer to a scientific question. Hypothesis. A hypothesis is a testable idea that explains an observation or answers a scientific question.

Law

A rule that always works under the same conditions. Law. In Science, a law is a statement describing a consistently observed natural phenomenon.

Model

A representation of an object or system. Model. In science, a model is a simplified way to understand and explain complex phenomena.

Scientific law

A rule that describes what happens in nature. Scientific law. A scientific law is a statement based on repeated experimental observations that describes an aspect of the world.

Technology

The use of scientific observations to solve practical problems. Technology. Technology is using science to create tools that make our lives easier.

Theory

Explanation of observations supported by evidence. Theory. In science, a theory is a well-tested idea that explains how or why something happens, based on evidence.

Variable

The factor that can change in an experiment. Variable. In science, a variable is anything that can be changed or controlled in an experiment to see its effects.

Volume

The amount of space an object takes up volume. Volume is the measure of how much space an object occupies.
