A wild guess without any evidence.

An untestable theory.

A proven fact in science.

A scientific guess without any evidence or testing.

A testable explanation for an observable phenomenon.

A scientific hypothesis is a testable explanation that serves as the basis for further investigation and experimentation to determine its validity.

Explanation

A scientific hypothesis is a testable explanation that serves as the basis for further investigation and experimentation to determine its validity.

6. What is applied research?

Conducting experiments to discover new scientific principles.

Studying theoretical concepts without any practical applications.

Applications of knowledge gained through basic research.

Analyzing existing data to draw new conclusions.

Applied research involves taking the knowledge and findings acquired through basic research and utilizing them in practical applications or real-world scenarios.

Explanation

8. What is a scientific law?

A scientific hypothesis supported by experimental data.

A theory that has not been tested in experiments.

An unproven scientific idea based on speculation.

A scientific hypothesis supported by experimental data.

A scientific law is a statement that describes an observable phenomenon based on repeated experimental observations. It is a descriptive generalization about how some aspect of the natural world behaves under certain circumstances.

Explanation

A scientific law is a statement that describes an observable phenomenon based on repeated experimental observations. It is a descriptive generalization about how some aspect of the natural world behaves under certain circumstances.

9. What is a scientific theory?

A hypothesis that has not been tested.

Unifies a broad range of observations within the natural world.

An educated guess based on limited information.

A proven fact that cannot be disputed.

An explanation that has been universally accepted by all scientists.

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. It unifies a broad range of observations and is supported by evidence.

Explanation
