Joe asked all of the students in his class if they liked pizza or not, and wrote down their answers. Was this a scientific exper
iment? (2 points) a No, because he did not create a graph using the numbers. b No, because he did not test anything, he asked people's opinions. c Yes, because he collected information. d Yes, because he had a hypothesis.
A scientific expiriment is one where a series of steps are developed to test a hypothesis. The scientist must develop many important steps to design a scientific experiment properly. Since he had surveyed his classmates, it would not be a scientific experiment. He didn't form a hypothesis, nor follow certain steps to get to a conclusion, hence as to why the answer is B.
