Worked practice questions

What is an experiment designed to do with a hypothesis?

  1. Replace it with a law
  2. Define it in words
  3. Publish it in a journal
  4. Support or refute it
Show answer and solution

Correct answer: D. Support or refute it

1. An experiment is a procedure carried out to test a hypothesis. 2. Its results either support the hypothesis or refute it. 3. Defining, publishing or replacing a hypothesis are not what an experiment itself does. _Source: Wikipedia, Experiment, lead section_

Experiments show cause and effect by doing what to one factor?

  1. Leaving it unchanged
  2. Only watching it
  3. Deliberately changing it
  4. Hiding it from view
Show answer and solution

Correct answer: C. Deliberately changing it

1. To see cause and effect, the experimenter changes one factor. 2. The outcome that follows is then compared with the unchanged situation. 3. Merely watching or leaving the factor alone gives observation, not an experiment. _Source: Wikipedia, Experiment, lead section_

Experiments always rely on a repeatable procedure and what else?

  1. Costly equipment
  2. Teacher opinions
  3. Majority agreement
  4. Logical analysis
Show answer and solution

Correct answer: D. Logical analysis

1. Experiments vary greatly in goal and scale. 2. What they share is a repeatable procedure and logical analysis of the results. 3. Expensive equipment, opinions and majority agreement are not required for an experiment. _Source: Wikipedia, Experiment, lead section_
