  • Q2
    How does a scientific theory differ from a scientific law?
    A theory is a fact and a law is a guess

  • Q4
    What is an essential characteristic of a scientific theory?
    It must remain unchanged forever
    It must be based on personal opinions
    It must be testable and falsifiable
    It can only be proven true

  • Q5
    Which statement best describes the role of evidence in forming a scientific theory?
    Theories are formed without using any evidence
    Evidence is crucial as it supports and validates the theory
