Understanding Scientific Theories and Laws

What is the main function of a scientific law?

• To provide a detailed explanation for observed phenomena.

• To predict the outcomes of specific conditions or events.

• To establish a universally accepted truth about nature.

• To guide the development of new scientific theories.

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

• A scientific law is a proven theory, while a theory is an unproven hypothesis.

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

• A scientific law is based on observation, while a scientific theory is based on speculation.

• A scientific law is universally accepted, while a scientific theory is often debated.

Johannes Kepler developed laws of planetary motion, but his theory about cosmic musical harmonies was later replaced. What does this illustrate about scientific progress?

• Scientific laws are more difficult to establish than theories.

• A theory can be incorrect even if it leads to valid laws.

• Theories are always less reliable than laws.

• Scientific understanding evolves as better explanations emerge.

Which statement best describes the nature of scientific theories?

• They are tentative ideas that will eventually become laws.

• They are explanations that can be disproven or revised with new evidence.

• They are absolute truths that cannot be challenged once established.

• They are less important than scientific laws in understanding the natural world.

What factor primarily influences scientists' acceptance of a new theory?

• Its popularity among the general public.

• Its ability to explain the majority of available data.

• Its alignment with existing religious or philosophical beliefs.

• Its simplicity and ease of understanding.

Even theories that are eventually discarded, like alchemy, can be valuable because they:

• Provide historical context for scientific thought.

• Often lead to the development of new scientific fields or methods.

• Demonstrate the fallibility of early scientific endeavors.

• Serve as warnings against pursuing unproven ideas.

How does the scientific community generally view challenges to established scientific theories?

• As a threat to existing knowledge that should be resisted.

• As an opportunity to refine or replace current explanations.

• As a sign of weakness in the scientific method.

• As irrelevant unless they come from within the scientific community.

Why are both scientific laws and theories considered essential for a complete understanding of science?

• Laws provide the facts, and theories provide the opinions.

• Laws describe phenomena, while theories explain the underlying mechanisms.

• Laws are for prediction, and theories are for observation.

• Laws are static, while theories are constantly changing.
