The answer is the last one (a hypothesis): "If plants are added to an indoor environment, the air quality will improve."

Explanation for each option:

  • A theory: A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has been repeatedly tested and confirmed through observation and experimentation. The student's statement is not a theory because it has not yet been tested or confirmed.
  • A procedure: A procedure is a series of actions conducted in a certain order or manner. The student's statement does not describe a series of actions or steps to be followed.
  • An observation: An observation is the act of noting and recording something with instruments or the senses. The student's statement is not an observation because it is not describing something that has been directly observed.
  • A hypothesis: A hypothesis is a tentative explanation or prediction that can be tested through experimentation and observation. The student's statement is a hypothesis because it is a testable prediction about the effect of plants on indoor air quality.

Summary: The student's statement, "If plants are added to an indoor environment, the air quality will improve," is an example of a hypothesis.
