## TL;DR
The Scientific Method: From Hypothesis to Theory: The scientific method is a disciplined process for asking questions, forming hypotheses, testing ideas, analyzing evidence, and revising explanations.

## Core Explanation
Real science is iterative rather than a rigid checklist. Observations lead to questions and hypotheses, experiments or observations test predictions, and evidence is evaluated through replication, peer criticism, and fit with existing knowledge.
