Unit 01 Mastery Quiz
Demonstrate essential understanding of investigable questions, variables, operational definitions, fair testing, measurement, data integrity, graphing, uncertainty, causal reasoning, CER, sources, and safety.
Independent attempt: answer from your own understanding. Do not use Mentor, PROSE, answer keys, external search, or another person to generate answers during an attempt. After submission, explanations become part of the correction cycle.
Attempt Result
Correction protocol: for each missed concept, write your original reasoning, why it failed, the corrected principle, and one new example. A retake is a new attempt after learning—not simply a chance to memorize answer positions.
