How do scientific theories evolve over time?

• They remain unchanged regardless of new evidence.

• They evolve as new evidence is discovered, leading to refinements or changes in understanding.

• They are only accepted if they are proven true beyond any doubt.

• They are based solely on the opinions of scientists.

What is a theory in science?

• A theory is a guess about how things work.

• A theory is a well-substantiated explanation of some aspect of the natural world that incorporates facts, laws, inferences, and tested hypotheses.

• A theory is an untested idea that may or may not be true.

• A theory is a collection of random observations.

What is the importance of data in forming scientific theories?

• Data is irrelevant to scientific theories.

• Data provides the evidence needed to support or refute a theory, making it more reliable and accepted in the scientific community.

• Data is only useful for statistical analysis, not for theory formation.

• Data can be manipulated to fit any theory regardless of its validity.

What is a scientific law?

• A statement that describes a consistent and universal relationship observed in nature, often expressed mathematically, but does not explain why it occurs.

• A hypothesis that has been tested and proven to be true in all cases.

• An observation that can be made in a laboratory setting only.

• A theory that explains the underlying reasons for natural phenomena.

Can a scientific law be demoted to a theory?

• True, a scientific law can be demoted to a theory.

• False. A scientific law cannot be demoted to a theory; they serve different purposes in science.

• Yes, scientific laws and theories are interchangeable.

• A scientific law can be upgraded to a theory.

What are scientific theories based on?

• A large number of personal opinions and beliefs.

• Large amounts of data collected over time.

• Random guesses and assumptions.

• A few isolated experiments and observations.

What is the difference between a scientific law and a scientific theory?

• A scientific law explains why something happens, while a scientific theory describes what happens.

• A scientific law describes what happens under certain conditions, while a scientific theory explains why it happens.

• A scientific law is a hypothesis that has not been tested, while a scientific theory is a proven fact.

• A scientific law and a scientific theory are the same thing and can be used interchangeably.

What is the role of experimentation in science?

• Experimentation is crucial for testing hypotheses and theories, allowing scientists to gather data and draw conclusions.

• Experimentation is primarily used to prove existing theories without any data collection.

• Experimentation is a method to avoid the use of scientific methods altogether.

• Experimentation is only necessary in the field of chemistry.

What is an example of a scientific theory?

• The Theory of Evolution, which explains the diversity of life through natural selection.

• The Law of Gravity, which describes the attraction between masses.

• The Big Bang Theory, which explains the origin of the universe.

• The Germ Theory of Disease, which states that microorganisms cause disease.

What role do hypotheses play in scientific theories?

• Hypotheses are untestable statements that cannot be proven or disproven.

• Hypotheses are testable predictions that can be supported or refuted through experimentation and observation, contributing to the development of theories.

• Hypotheses are merely guesses that do not require any evidence.

• Hypotheses are conclusions drawn from existing theories without further testing.
