Answer
The correct answer is: Experiments 1 and 2 represent scientific repetition.
Explanation
In scientific terminology, "repetition" refers to performing the same experiment multiple times by the same set of investigators to verify the results. "Replication," on the other hand, refers to different investigators conducting the same experiment independently to verify the findings of the original experiment.- If both experiments are performed by the same students (Mr. Goff's class), then "repetition" is a more suitable term.- If one experiment is repeated by the same students and another is conducted independently by a different group, this mix exemplifies both terms.
