Scientific Inquiry and Research Principles

The video explores scientific inquiry, focusing on the assumptions of natural causes, evidence, and consistency. It discusses the importance of peer review and publication in the scientific process. The video also defines key scientific terms like facts, laws, and theories, and examines bias in science, including unintentional and intentional bias.

What is one of the basic assumptions of science regarding natural phenomena?

• They have supernatural causes.

• They have natural causes.

• They are random and unpredictable.

• They cannot be explained.

Why is evidence crucial in scientific inquiry?

• It is not necessary for scientific conclusions.

• It helps in forming unchangeable dogmas.

• It allows for supernatural explanations.

• It enables learning about natural causes.

What does the assumption that nature is ordered and consistent imply?

• Nature is chaotic and unpredictable.

• Similar conditions yield similar results.

• Experiments cannot be replicated.

• Scientific results can vary widely.

What is the purpose of the peer review process in science?

• To ensure supernatural explanations are included.

• To verify the quality and reliability of research.

• To publish findings without scrutiny.

• To prevent any changes to scientific theories.

Why is replicability important in scientific experiments?

• It allows for unique, one-time results.

• It ensures that findings are consistent and reliable.

• It prevents other scientists from verifying results.

• It is not a significant aspect of scientific research.

How does science define a 'fact'?

• A theory that has become a law.

• A hypothesis waiting to be proven.

• An observable and verifiable truth.

• A belief held without evidence.

What distinguishes a scientific theory from a hypothesis?

• A theory is a guess, while a hypothesis is proven.

• A theory is a well-supported explanation, not a guess.

• A hypothesis is more reliable than a theory.

• A theory is waiting to become a law.

What is the role of bias in scientific research?

• Bias is always intentional and harmful.

• Bias can be both unintentional and intentional.

• Bias is irrelevant in scientific studies.

• Bias is necessary for scientific progress.

How do blind trials help in scientific research?

• They are only used in non-scientific studies.

• They ensure all participants know the experiment details.

• They prevent bias by keeping information from some participants.

• They allow researchers to manipulate results.

What is a placebo in the context of a blind trial?

• A method to ensure bias in research.

• A variable that changes the experiment outcome.

• A fake treatment used as a control.

• A real medicine used in experiments.
