Nature of Science

What is a scientific model?

• A representation of an object, system, or concept that helps to explain and predict phenomena in the natural world.

• A detailed description of a scientific experiment.

• A collection of data points used to analyze trends.

• A theoretical framework that cannot be tested.

What represents ethical behavior in scientific investigation?

• Accurate reporting of results and allowing others to review your work.

• Conducting experiments without any oversight.

• Publishing results without peer review.

• Exposing test subjects to unnecessary risks.

What is the scientific method?

• A systematic process that uses observation and experimentation to gain knowledge about events in nature.

• A random approach to understanding natural phenomena.

• A method that relies solely on theoretical assumptions without experimentation.

• A way to conduct research without any structured process.

What is the significance of reproducibility in science?

• It allows researchers to publish findings without verification.

• It enables other researchers to verify results and confirm findings through repeated experiments.

• It reduces the need for peer review in scientific publications.

• It ensures that all experiments yield the same results every time.

What is an independent variable?

• A variable that is measured in an experiment.

• A variable that is kept constant throughout the experiment.

• A factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

• A variable that does not affect the outcome of the experiment.

What is the dependent variable?

• The factor that is manipulated in an experiment.

• The factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

• The constant factor that remains unchanged throughout the experiment.

• The hypothesis that is tested during the experiment.

What is an experiment?

• A method to collect data without a hypothesis.

• A procedure carried out to support, refute, or validate a hypothesis.

• A way to analyze past data without conducting new tests.

• A technique used only in scientific research.

What is the importance of peer review in science?

• It helps validate research findings, ensures accuracy, and maintains quality in scientific literature.

• It allows researchers to publish their work without scrutiny.

• It is a method to increase the number of publications.

• It serves as a marketing tool for scientific journals.

What is the goal of a scientific investigation?

• To entertain the audience

• To help the scientist solve a problem or answer a question.

• To create new technology

• To prove a hypothesis without evidence.

What is a theory in science?

• A theory is a guess about how things work.

• A theory is a well-substantiated explanation of some aspect of the natural world, based on a body of evidence and repeatedly tested through observation and experimentation.

• A theory is an untested hypothesis.

• A theory is a simple statement that describes a phenomenon.
