Scientists differ greatly in what phenomena they study and how they
go about their work. Although there is no fixed set of steps that all scientists
follow, scientific investigations usually involve the collection of relevant
evidence, the use of logical reasoning, and the application of imagination
in devising hypotheses and explanations to make sense of the collected
evidence.
NSES Content Standard A
Science as Inquiry: Abilities necessary to do scientific inquiry Grades 5-8, page 145 Develop descriptions, explanations, predictions, and models using evidence. Students should base their explanation on what they observed, and as they develop cognitive skills, they should be able to differentiate explanation from description--providing causes for effects and establishing relationships based on evidence and logical argument. This standard requires a subject matter knowledge base so the students can effectively conduct investigations, because developing explanations establishes connections between the content of science and the contexts within which students develop new knowledge.
