Empirical evidence in science is information gathered through direct or indirect observation or experimentation that is used to confirm or deny a scientific theory.

a well-tested, broad explanation for a natural phenomenon that is supported by a large body of evidence.

A scientific law is a concise, descriptive statement based on repeated experiments or observations that predicts or summarizes how a natural phenomenon behaves under specific conditions

experiment is a structured scientific test used to study how a process or phenomenon works, typically by changing one factor to see its effect on another.

A hypothesis is a proposed, testable explanation for a phenomenon or observation based on prior research and scientific knowledge.

the factor that a scientist measures in an experiment to see how it responds to a change.

An observation in science is the active acquisition of information, data, or facts about the natural world using the human senses or scientific instruments.

the specific factor that a scientist changes or manipulates in an experiment to test its effects.

data refers to the factual information, measurements, numbers, or observations gathered through research, experiments, and systematic study.

a physical, mathematical, or conceptual representation of a real-world system, object, or phenomenon that helps scientists explain, visualize, and predict how things work.

the practical application of science, mathematics, and technology to design, build, and create solutions for real-world problems.

Technology in science means the practical application of scientific knowledge, principles, and tools to solve human problems, meet practical needs, and modify the environment.

A prototype is an early, experimental model of a device or product built to test how a design performs in the real world.

a situation where improving one trait, function, or quality forces a reduction or loss in another.

a science-based method used to measure the total environmental impact of a product, material, or service across its entire life span—from raw material extraction to final disposal or recycling.

A Pugh chart—also called a Pugh matrix or decision matrix—is a decision-making tool used to compare multiple ideas or design alternatives against a baseline reference point.

risk-benefit analysis

the process of comparing the expected negative outcomes (risks) of an action, substance, or technology against its anticipated positive outcomes (benefits) to decide if it should be used.
