Characteristics of Scientific Knowledge

What is one of the main characteristics of scientific knowledge?

• It is based on personal opinions.

• It is based on empirical evidence.

• It is unchangeable.

• It is always speculative.

Which of the following best describes a scientific theory?

• A guess about how something works.

• A well-substantiated explanation of some aspect of the natural world.

• A law that has been proven true.

• An untested idea.

How do scientific laws differ from scientific theories?

• Laws describe phenomena, while theories explain them.

• Laws are more important than theories.

• Theories are guesses, while laws are facts.

• Laws can never be changed, but theories can.

Which of the following is an example of a scientific model?

• A physical replica of the solar system.

• A scientist's personal belief.

• A random guess about a phenomenon.

• A fictional story about space.

Why do scientists use models?

• To simplify complex systems and make predictions.

• To replace experiments.

• To avoid using mathematics.

• To prove their theories.

Which of the following statements is true about scientific knowledge?

• It is static and never changes.

• It evolves with new evidence and discoveries.

• It is based solely on intuition.

• It is always completely certain.

What role do experiments play in science?

• They are used to test hypotheses and theories.

• They are used to prove laws.

• They are unnecessary in modern science.

• They are only used in physics.

Which of the following is a characteristic of a good scientific model?

• It is overly complex and difficult to understand.

• It accurately represents the system it is modeling.

• It is based on assumptions without evidence.

• It is static and unchangeable.

How do scientists use mathematical models in science?

• To create artistic representations.

• To make precise predictions and analyze data.

• To avoid conducting experiments.

• To replace physical models.

What is the importance of peer review in science?

• It ensures that scientific work is free from errors and biases.

• It allows scientists to publish without scrutiny.

• It is only necessary for controversial topics.

• It is a formality with no real impact.
