What is the primary role of a scientific theory?

  1. To provide a comprehensive explanation of all natural phenomena.

  2. To make accurate predictions about future events.

  3. To organize and classify known facts.

  4. To generate new hypotheses for further investigation.


Correct Option: A
Explanation:

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

What is the difference between a theory and a hypothesis?

  1. A theory is more general than a hypothesis.

  2. A theory is more specific than a hypothesis.

  3. A theory is based on more evidence than a hypothesis.

  4. A theory has been tested more rigorously than a hypothesis.


Correct Option: A
Explanation:

A theory is a broad explanation of a natural phenomenon that is supported by evidence, while a hypothesis is a more specific, testable prediction that is derived from a theory.

What are the two main types of scientific explanations?

  1. Deductive and inductive.

  2. Causal and teleological.

  3. Mechanistic and functional.

  4. Structural and dynamic.


Correct Option: A
Explanation:

Deductive explanations start with general principles and use logic to derive specific conclusions, while inductive explanations start with specific observations and use reasoning to arrive at general conclusions.

What is the difference between a causal explanation and a teleological explanation?

  1. A causal explanation focuses on the causes of an event, while a teleological explanation focuses on the purpose or goal of an event.

  2. A causal explanation is based on evidence, while a teleological explanation is based on faith.

  3. A causal explanation is more scientific than a teleological explanation.

  4. A teleological explanation is more scientific than a causal explanation.


Correct Option: A
Explanation:

Causal explanations focus on the events or conditions that bring about a particular outcome, while teleological explanations focus on the purpose or goal that an event or process is intended to achieve.

What is the role of evidence in scientific explanation?

  1. Evidence is used to support or refute a theory.

  2. Evidence is used to generate new hypotheses.

  3. Evidence is used to test the validity of a theory.

  4. All of the above.


Correct Option: D
Explanation:

Evidence plays a crucial role in scientific explanation by providing support for or refuting theories, generating new hypotheses, and testing the validity of theories.

What is the relationship between theory and explanation in science?

  1. Theories provide explanations for phenomena.

  2. Explanations provide evidence for theories.

  3. Theories and explanations are independent of each other.

  4. None of the above.


Correct Option: A
Explanation:

Theories provide explanations for phenomena by offering a framework for understanding how and why things happen.

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

  1. A theory is a general explanation of a natural phenomenon, while a law is a specific statement of how a natural phenomenon behaves.

  2. A theory is based on evidence, while a law is based on observation.

  3. A theory is more likely to change than a law.

  4. All of the above.


Correct Option: D
Explanation:

A scientific theory is a general explanation of a natural phenomenon that is supported by evidence, while a scientific law is a specific statement of how a natural phenomenon behaves that is based on observation. Theories are more likely to change than laws because they are based on more evidence and are subject to revision as new evidence is discovered.

What is the role of models in scientific explanation?

  1. Models provide a simplified representation of a complex system.

  2. Models can be used to make predictions about the behavior of a system.

  3. Models can be used to test hypotheses.

  4. All of the above.


Correct Option: D
Explanation:

Models play a crucial role in scientific explanation by providing a simplified representation of a complex system, allowing scientists to make predictions about the behavior of the system, and testing hypotheses.

What is the difference between a conceptual model and a mathematical model?

  1. A conceptual model is a qualitative representation of a system, while a mathematical model is a quantitative representation of a system.

  2. A conceptual model is more abstract than a mathematical model.

  3. A conceptual model is easier to understand than a mathematical model.

  4. All of the above.


Correct Option: D
Explanation:

A conceptual model is a qualitative representation of a system that is easier to understand than a mathematical model, while a mathematical model is a quantitative representation of a system that is more abstract.

What is the role of analogy in scientific explanation?

  1. Analogies can help to make complex concepts more understandable.

  2. Analogies can be used to generate new hypotheses.

  3. Analogies can be used to test theories.

  4. All of the above.


Correct Option: D
Explanation:

Analogies play a valuable role in scientific explanation by helping to make complex concepts more understandable, generating new hypotheses, and testing theories.

What is the difference between a deductive argument and an inductive argument?

  1. A deductive argument starts with general premises and uses logic to derive a specific conclusion, while an inductive argument starts with specific observations and uses reasoning to arrive at a general conclusion.

  2. A deductive argument is always valid, while an inductive argument is not always valid.

  3. A deductive argument is more reliable than an inductive argument.

  4. None of the above.


Correct Option: A
Explanation:

A deductive argument starts with general premises and uses logic to derive a specific conclusion, while an inductive argument starts with specific observations and uses reasoning to arrive at a general conclusion. Deductive arguments are always valid, but inductive arguments are not always valid.

What is the role of falsification in scientific explanation?

  1. Falsification is the process of testing a hypothesis by trying to prove it false.

  2. Falsification is the process of confirming a hypothesis by gathering evidence in its favor.

  3. Falsification is the process of generating new hypotheses.

  4. None of the above.


Correct Option: A
Explanation:

Falsification is the process of testing a hypothesis by trying to prove it false. If a hypothesis can be falsified, then it is not a valid explanation for the phenomenon in question.

What is the difference between a strong theory and a weak theory?

  1. A strong theory is supported by more evidence than a weak theory.

  2. A strong theory has been tested more rigorously than a weak theory.

  3. A strong theory is more likely to be true than a weak theory.

  4. All of the above.


Correct Option: D
Explanation:

A strong theory is supported by more evidence, has been tested more rigorously, and is more likely to be true than a weak theory.

What is the role of explanation in science?

  1. Explanation is the process of providing a rational account of why something happens.

  2. Explanation is the process of generating new hypotheses.

  3. Explanation is the process of testing theories.

  4. None of the above.


Correct Option: A
Explanation:

Explanation is the process of providing a rational account of why something happens. It is an essential part of science because it allows scientists to understand the world around them and to make predictions about future events.

What are the different types of scientific explanations?

  1. Causal explanations.

  2. Teleological explanations.

  3. Mechanistic explanations.

  4. All of the above.


Correct Option: D
Explanation:

There are three main types of scientific explanations: causal explanations, teleological explanations, and mechanistic explanations. Causal explanations focus on the causes of an event, teleological explanations focus on the purpose or goal of an event, and mechanistic explanations focus on the underlying mechanisms that produce an event.
