Theories vs Laws

What is the scientific method?

• A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

• A random approach to solving problems without any structured methodology.

• A method used exclusively in laboratory settings for conducting experiments.

• A philosophical approach to understanding the universe without empirical evidence.

What is a hypothesis?

• A hypothesis is a testable prediction about the relationship between variables in an experiment.

• A hypothesis is a proven fact that does not require testing.

• A hypothesis is an observation made during an experiment.

• A hypothesis is a conclusion drawn after analyzing data.

Can scientific theories change?

• No, scientific theories are always fixed.

• Yes, scientific theories can change when new evidence is discovered.

• Only if they are proven wrong.

• Scientific theories never change.

What is an example of a scientific law?

• Newton's Law of Universal Gravitation, which describes the gravitational attraction between masses.

• Einstein's Theory of Relativity, which explains the relationship between space and time.

• The Law of Conservation of Energy, which states that energy cannot be created or destroyed.

• Darwin's Theory of Evolution, which describes the process of natural selection.

What role does evidence play in scientific theories?

• Evidence is crucial for developing, supporting, and revising scientific theories.

• Evidence is only needed for developing theories, not for supporting them.

• Evidence is irrelevant to scientific theories and their development.

• Evidence is used to disprove scientific theories rather than support them.

What is a scientific law?

• A statement that describes a consistent and universal relationship observed in nature, often expressed mathematically.

• A hypothesis that has been tested multiple times and is widely accepted.

• An observation that cannot be replicated under any circumstances.

• A theory that explains a broad range of phenomena but is not universally applicable.

What is the significance of a variable in an experiment?

• A variable is a fixed factor that does not change during an experiment.

• A variable is any factor that can change in an experiment, and it is essential for testing hypotheses.

• A variable is only important in observational studies, not experiments.

• A variable is a measurement that is always constant throughout the experiment.

What is peer review?

• A process where scientific work is evaluated by other experts in the field before publication.

• A method of collecting data from participants in a study.

• A technique for analyzing statistical data in research.

• A way to publish research without any evaluation.

What is an example of a scientific theory?

• Theory of Evolution, which explains how species change over time through natural selection.

• Theory of Relativity, which describes the relationship between space and time.

• Big Bang Theory, which explains the origin of the universe.

• Plate Tectonics, which describes the movement of Earth's plates.

What does it mean when a theory is described as 'well-supported'?

• A well-supported theory is one that has been extensively tested and confirmed by multiple lines of evidence.

• A well-supported theory is one that is popular among scientists but lacks substantial evidence.

• A well-supported theory is one that has been proposed but not yet tested.

• A well-supported theory is one that is based on personal beliefs rather than scientific evidence.
