Concept explainers
Interpretation: The correct passage for an experiment needs to be determined.
Concept Introduction: The scientific method is a systematic way of collecting evidence to support theories/ concepts. This helps to explain the nature around us. In scientific disciplines, the term “model”, “experiment”, “observation”, “theory” and “law” holds different meanings of phenomena.

Answer to Problem 5STP
Correct answer: Option B.
Explanation of Solution
Reason for correct option:
An experiment is a way to test a hypothesis; where hypothesis is a testable, tentative explanation for observations. Controlled, field, and natural experiments are three main types of experiments.
According to this, dropping a raisin into water to see if it behaves the same way as when it is in ginger ale, is an experiment. This experiment is also known as “Dancing Raisins Experiment”.
