We’re being asked to classify each statement as an observation, a law, or a theory. But first, let’s see what is the difference between an observation, a law, and a theory.


Observation

▪ what you see or observe what is physically happening through measurements in terms of an experiment

Law

▪ based on observation
▪ states what’s occurring or predict what’s going to happen through observations

Theory
