Final answer:
Joe is conducting a replication of Jill's experiment to verify the original results. Replication involves performing the same experiment with the same procedures to confirm the findings. The experiment must be carefully documented to ensure accurate replication and contribution to scientific understanding.
Step-by-step explanation:
Joe is performing a replication of Jill’s experiment. In scientific research, replication is a crucial step that involves conducting the same experiment again to verify the results obtained by the original experiment. By carefully following Jill’s procedure, Joe can ensure that any variations in results are due to the experimental conditions and not due to the way the experiment was conducted.
An experiment is a type of scientific investigation that is performed under controlled conditions to test a hypothesis. It involves manipulating an independent variable to observe its effect on a dependent variable. In Jill and Joe’s case, the independent variable might be the size of the fish tank, and the dependent variable would be the growth of the fish.
The scientific method emphasizes the importance of detailed record-keeping so that others can replicate the work. Therefore, Joe should document all aspects of the experimental procedure, including the materials used, detailed steps taken, and any observations and data collected. This approach ensures that the experiment can contribute meaningful evidence to the scientific community and help in understanding the phenomenon being studied.
