Students will experience an unfair investigation challenge, identify why a test is not fair, and generate an initial investigable question connected to school or everyday life for refinement in the next phase.

Students will refine a question they care about into a testable investigation, write a hypothesis grounded in a simple scientific idea, and build a fair-test plan with variables, controls, criteria, and constraints. They will use structured peer critique and teacher feedback to revise both their question and method before moving into data collection.

Students will organize and verify their investigation evidence, create clear data displays, interpret patterns and anomalies, write evidence-based conclusions with limitations and next steps, and prepare a concise presentation that explains how their fair test addressed the original question.

Students will present their fair-test investigations to an authentic audience, defend how their method addressed variables and confounding effects, and complete a brief evidence-based reflection on what made their test fair and how they would improve it next.
