Exploring Scientific Concepts and Methods

Which of the following best explains why scientific knowledge is considered durable?

• It is based on opinions that do not change.

• It is open to change as new evidence or interpretations are encountered.

• It is never questioned once established.

• It is based on historical beliefs.

What is the main difference between replication and repetition in scientific experiments?

• Replication involves repeating the same experiment multiple times.

• Repetition involves different scientists conducting the same experiment.

• Replication involves different scientists conducting the same experiment.

• Repetition involves changing the variables of the experiment.

Which method is commonly used in biology to explain scientific phenomena?

• Geological surveys

• Chemical reactions

• Systematic observations

• Mathematical modeling

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

• Newton's Law of Universal Gravitation

• The Theory of Evolution

• The Law of Conservation of Mass

• Ohm's Law

When defining a scientific problem, which of the following is essential?

• Using personal opinions

• Using appropriate reference materials

• Ignoring previous research

• Relying solely on intuition

Why is it important for scientific knowledge to be open to change?

• To ensure it remains static and unchallenged

• To allow for the incorporation of new evidence

• To prevent any form of criticism

• To maintain traditional beliefs

In a scientific experiment, what does repetition help to ensure?

• The experiment is conducted by different scientists

• The results are consistent and reliable

• The variables are changed each time

• The experiment is only conducted once

Which scientific field primarily uses experiments to explain phenomena?

• Astronomy

• Geology

• Physics

• Sociology

What distinguishes a scientific theory from a scientific law?

• Theories are proven facts, while laws are hypotheses.

• Theories explain phenomena, while laws describe them.

• Laws are more flexible than theories.

• Theories are less supported by evidence than laws.

Which step is crucial when planning a scientific investigation?

• Ignoring data collection

• Identifying variables

• Avoiding systematic observations

• Disregarding previous studies
