Study Guide Objectives WK 1- The Nature of Science

Compare and contrast science with other ways of learning

Science uses evidence, testing, and reasoning (question, hypothesis, theories), while other ways of learning rely on belief, experience, or having an authority.

What is the difference between scientific questions, theories, and hypotheses?

• Scientific Questions= should be focused, usually based on hypotheses

• Theories= a well supported explanation of how an observed phenomenon works

• Hypotheses= prediction based on what you already know about the subject

Describe the important aspects of a properly phrased scientific question. What does it mean for a question to be testable?

Properly phrased scientific question example:

• Does influenza spread from chickens to pigs by the air?

Important aspects of a properly phrased scientific question:

• Clear, specific, and testable with evidence

What does it mean for a question to be testable?

• For a question to be testable, it means it can be answered with measurable data and evidence

How do you interpret a data graph? What are dependent and independent variables?

What is the difference between experimental studies and observational studies? When would you do each one?

What is the purpose of negative controls and positive controls?

Given a set of experimental results, be able to draw conclusions that will confirm or reject the original hypothesis.

What are the three domains of life?

How are structure and function related?

What is the one idea that forms the basis for all current biology?
