Examine the situation.
Lloyd is studying the effect of breakfast cereal on the health of rats. He suspects that the cereal may be unhealthy. He feeds rats various amounts of breakfast cereal over a six-week period. He weighs the rats using a digital lab balance at the beginning of the experiment and then again at the end of the experiment. Then, he calculates the change in weight.
When writing the conclusion of his report, Lloyd states that the breakfast cereal is not a healthy choice for school children since it causes them to gain weight unnecessarily.
What component of scientific argumentation is missing from Lloyds work?
appropriate equipment for use in the experiment
graphs and tables in the written report
empirical data that supports his claim
accurate measurements made during the experiment
B?
In scientific argumentation, however, explanations are generated, verified, communicated, debated, and modified. Ideally, the goal of all participants in scientific argumentation is to refine and build consensus for scientific ideas, based on evidence, to come as close as possible to understanding the reality of the natural world.
I would go with C over B
