Unit 3: Scientific Reasoning & Problem Solving Quiz

What is the definition of bias?

• Looking at and judging a problem without bias

• Favoritism toward one idea or group

• Logic based on the scientific method

• Facts observed by the human eye or gathered as a result of experimentation

What is the scientific method?

• A systematic procedure scientists use to solve problems

• Finding solutions to questions based on empirical evidence

• Math/scientific equations used as a representation of a concept in the natural world

• A representation helping explain the natural world

What is empirical evidence?

• Logic based on the scientific method

• Facts gathered through observation or experimentation which support or do not support an idea

• A tangible (touchable) representation of something in the natural world

• A potential answer to a question

What does peer-reviewed mean?

• A systematic procedure scientists use to solve problems

• Facts observed by the human eye or gathered as a result of experimentation

• Subjected to review by other members of the professional community

• A representation used to illustrate an abstract idea or concept which may not be physical

What is a hypothesis?

• A systematic procedure scientists use to solve problems

• A potential answer to a question

• A variable which is manipulated by the scientist and does not change

• A well-established and highly reliable scientific statement based on natural and physical phenomena

What is an independent variable?

• A variable which is manipulated by the scientist and does not change

• A variable which is observed or measured and can change as the independent variable is altered

• A constant and unchanged variable throughout the course of the experiment

• An ineffective medicine or treatment prescribed more for psychological benefit to the patient than for any physiological effect

What is a constant variable?

• A variable which is manipulated by the scientist and does not change

• A variable which is observed or measured and can change as the independent variable is altered

• A constant and unchanged variable throughout the course of the experiment

• An ineffective medicine or treatment prescribed more for psychological benefit to the patient than for any physiological effect

What is a double-blind experiment?

• A systematic procedure scientists use to solve problems

• A test in which neither the scientists nor the subjects know which test group is which

• A well-established and highly reliable scientific statement based on natural and physical phenomena

• A field appearing scientific, but not considered to be science

What is a theory?

• A systematic procedure scientists use to solve problems

• A potential answer to a question

• A well-established and highly reliable scientific statement based on natural and physical phenomena

• A representation used to illustrate an abstract idea or concept which may not be physical

What is a physical model?

• A tangible (touchable) representation of something in the natural world

• A representation helping explain the natural world

• Math/scientific equations used as a representation of a concept in the natural world

• A field appearing scientific, but not considered to be science
