What is a scientific theory?

  1. A well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method.

  2. A guess or an idea that is not supported by evidence.

  3. A set of beliefs or principles that is not based on scientific evidence.

  4. A collection of facts that have been gathered through observation and experimentation.


Correct Option: A
Explanation:

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method. It is based on evidence and observation and is subject to revision and refinement as new evidence emerges.

What is a hypothesis?

  1. A well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method.

  2. A guess or an idea that is not supported by evidence.

  3. A set of beliefs or principles that is not based on scientific evidence.

  4. A collection of facts that have been gathered through observation and experimentation.


Correct Option: B
Explanation:

A hypothesis is a guess or an idea that is not supported by evidence. It is a starting point for scientific investigation and is subject to testing and verification through experimentation and observation.

What is the difference between a theory and a hypothesis?

  1. A theory is a well-substantiated explanation that is supported by evidence, while a hypothesis is a guess or an idea that is not supported by evidence.

  2. A theory is a set of beliefs or principles that is not based on scientific evidence, while a hypothesis is a guess or an idea that is not supported by evidence.

  3. A theory is a collection of facts that have been gathered through observation and experimentation, while a hypothesis is a guess or an idea that is not supported by evidence.

  4. There is no difference between a theory and a hypothesis.


Correct Option: A
Explanation:

A theory is a well-substantiated explanation that is supported by evidence, while a hypothesis is a guess or an idea that is not supported by evidence. Theories are based on extensive research and experimentation, while hypotheses are starting points for scientific investigation.

What are the steps involved in the scientific method?

  1. Observation, hypothesis, experimentation, analysis, and conclusion.

  2. Hypothesis, experimentation, observation, analysis, and conclusion.

  3. Observation, experimentation, hypothesis, analysis, and conclusion.

  4. Experimentation, observation, hypothesis, analysis, and conclusion.


Correct Option: A
Explanation:

The scientific method involves a series of steps: observation, hypothesis, experimentation, analysis, and conclusion. It is a systematic approach to investigating and understanding the natural world.

What is the role of evidence in scientific inquiry?

  1. Evidence is used to support or refute hypotheses.

  2. Evidence is used to generate new theories.

  3. Evidence is used to confirm existing theories.

  4. Evidence is used to make predictions about the natural world.


Correct Option: A
Explanation:

Evidence is used to support or refute hypotheses. It is the foundation of scientific inquiry and is used to test and verify the validity of scientific claims.

What is the difference between a law and a theory in science?

  1. A law is a statement that describes a natural phenomenon, while a theory is an explanation of why the phenomenon occurs.

  2. A law is a statement that is based on evidence, while a theory is a statement that is not based on evidence.

  3. A law is a statement that is universal, while a theory is a statement that is specific.

  4. A law is a statement that is falsifiable, while a theory is a statement that is not falsifiable.


Correct Option: A
Explanation:

A law is a statement that describes a natural phenomenon, while a theory is an explanation of why the phenomenon occurs. Laws are based on observation and experimentation, while theories are based on evidence and reasoning.

What is the role of falsification in scientific inquiry?

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

  2. Falsification is the process of testing a hypothesis by trying to prove it true.

  3. Falsification is the process of generating new hypotheses.

  4. Falsification is the process of confirming existing theories.


Correct Option: A
Explanation:

Falsification is the process of testing a hypothesis by trying to prove it false. It is a fundamental principle of scientific inquiry and is used to determine the validity of scientific claims.

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

  1. A deductive argument is a logical argument that proceeds from general premises to a specific conclusion, while an inductive argument is a logical argument that proceeds from specific premises to a general conclusion.

  2. A deductive argument is a logical argument that is based on evidence, while an inductive argument is a logical argument that is not based on evidence.

  3. A deductive argument is a logical argument that is universal, while an inductive argument is a logical argument that is specific.

  4. A deductive argument is a logical argument that is falsifiable, while an inductive argument is a logical argument that is not falsifiable.


Correct Option: A
Explanation:

A deductive argument is a logical argument that proceeds from general premises to a specific conclusion, while an inductive argument is a logical argument that proceeds from specific premises to a general conclusion. Deductive arguments are based on the principle of syllogism, while inductive arguments are based on the principle of generalization.

What is the role of models in scientific inquiry?

  1. Models are used to represent and simplify complex phenomena.

  2. Models are used to generate new hypotheses.

  3. Models are used to confirm existing theories.

  4. Models are used to make predictions about the natural world.


Correct Option: A
Explanation:

Models are used to represent and simplify complex phenomena. They are used to visualize and understand the relationships between different variables and to make predictions about the behavior of a system.

What is the difference between a theory and a law in science?

  1. A theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method, while a law is a statement that describes a natural phenomenon.

  2. A theory is a guess or an idea that is not supported by evidence, while a law is a statement that is based on evidence.

  3. A theory is a set of beliefs or principles that is not based on scientific evidence, while a law is a statement that is based on scientific evidence.
