Understanding the Nature of Science

Mr. Andersen discusses the nature of science, emphasizing it as a way of knowing the natural world through evidence and skepticism. Science is a human endeavor, subject to change and improvement over time. It involves forming hypotheses, testing them, and building theories. The video highlights the role of technology and collaboration in scientific discovery, and distinguishes between facts, laws, and hypotheses. It also addresses the limitations of science in answering supernatural or ethical questions.

What sets science apart from other ways of knowing?

• It focuses on supernatural phenomena.

• It uses a specific method to understand the natural world.

• It is based on assumptions without evidence.

• It relies on faith and belief.

Which of the following questions cannot be answered by science?

• Does God exist?

• How do plants photosynthesize?

• What causes gravity?

• What is the speed of light?

How do scientists typically share their discoveries with others?

• By publishing in research journals

• By writing novels

• Through social media

• By keeping them secret

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

• A theory is always correct, while a law can change.

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

• A law is a description of observed phenomena, while a theory explains why they occur.

• A law explains why phenomena occur, while a theory describes them.

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

• The theory of relativity

• The hypothesis of evolution

• The law of gravity

• An apple falling from a tree

What is required for a hypothesis to be considered scientific?

• It must be popular.

• It should be testable and falsifiable.

• It should be complex.

• It must be proven true.

How did John Snow contribute to the understanding of disease spread?

• By developing the theory of evolution

• By discovering the miasma theory

• By identifying the source of a cholera outbreak

• By inventing the microscope

What does the example of gravitational waves illustrate about scientific discovery?

• Scientific discoveries are always accidental.

• Scientific discoveries often require technological advancements.

• Science is based on assumptions.

• Scientific theories are never revised.

What does the process of critiquing in science help achieve?

• It helps improve and refine scientific understanding.

• It focuses only on disproving existing theories.

• It ensures that scientific knowledge remains unchanged.

• It discourages new scientific ideas.

What is the significance of the germ theory in the history of science?

• It was developed by Isaac Newton.

• It replaced the miasma theory with evidence-based understanding.

• It was the first scientific theory.

• It proved the miasma theory correct.
