Kaylee reads an article that states that the frequency of chirping by crickets is related to the temperature of their environment. She wants to conduct an experiment to see if this is true. Kaylee states this hypothesis: Crickets chirp more frequently when the temperature of their environment increases.
What is the test variable (independent variable) and outcome variable (dependent variable) in Kaylee's experiment?
A. test variable (independent variable): temperature of environment; outcome variable (dependent variable): frequency of chirping
B. test variable (independent variable): number of crickets; outcome variable (dependent variable): frequency of chirping
C. test variable (independent variable): number of crickets; outcome variable (dependent variable): temperature of environment
D. test variable (independent variable): frequency of chirping; outcome variable (dependent variable): temperature of environment

Astudent completed a lab report. which correctly describes the difference between the “question” and “hypothesis” sections of her report? “question” states what she is asking, and “hypothesis” states the result of her experiment. “question” states what she is asking, and “hypothesis” states what she thinks the answer to that question is in “if . . then . . because” format. “question” describes what she is trying to find out, and "hypothesis" states the procedures and methods of data collection. “question” describes what she is trying to find out, and “hypothesis” states any additional information or prior knowledge about the question.
