Intro, NOS & Scientific Method

What is a scientific theory?

• A well-tested concept that explains a wide range of observations

• A statement that describes what scientists expect to happen every time

• A testable prediction, often implied by a theory

• A conclusion reached on the basis of evidence and reasoning

What does a scientific law describe?

• A well-tested concept that explains a wide range of observations

• A statement that describes what scientists expect to happen every time under a particular set of conditions

• A testable prediction, often implied by a theory

• A conclusion reached on the basis of evidence and reasoning

What is an inference?

• Information obtained through the senses

• A conclusion reached on the basis of evidence and reasoning

• A statement that describes what scientists expect to happen every time

• A well-tested concept that explains a wide range of observations

What is the scientific method?

• A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions

• A statement that describes what scientists expect to happen every time

• A testable prediction, often implied by a theory

• A conclusion reached on the basis of evidence and reasoning

What is a hypothesis?

• A testable prediction, often implied by a theory

• A well-tested concept that explains a wide range of observations

• A statement that describes what scientists expect to happen every time

• A conclusion reached on the basis of evidence and reasoning

What is an experiment?

• A conclusion reached on the basis of evidence and reasoning

• A testable prediction, often implied by a theory

• A statement that describes what scientists expect to happen every time

• A research method in which an investigator manipulates one or more factors to observe the effect on some behavior or mental process

What does it mean to analyze?

• To manipulate one or more factors to observe the effect

• To collect data for reference or analysis

• To arrange or order by classes or categories

• To break down in order to bring out the essential elements or structure

What does it mean to classify?

• To arrange or order by classes or categories

• To break down in order to bring out the essential elements or structure

• To manipulate one or more factors to observe the effect

• To collect data for reference or analysis

What is data?

• A testable prediction, often implied by a theory

• A statement that describes what scientists expect to happen every time

• Facts and statistics collected together for reference or analysis

• A conclusion reached on the basis of evidence and reasoning

What are variables?

• A conclusion reached on the basis of evidence and reasoning

• Any measurable conditions, events, characteristics, or behaviors that are controlled or observed in a study

• A statement that describes what scientists expect to happen every time

• A testable prediction, often implied by a theory
