FRQ Scientific Reasoning
Core Sentence / 核心句
A complete scientific response states a claim, invokes the relevant principle, shows the causal or mathematical link, and returns to the requested conclusion.
Answer Frame / 作答骨架
Claim -> physical principle -> equation/evidence -> reasoning -> conclusion with units or comparison.
Watch Out / 易错点
只写结论、只抄公式或用结果解释结果，都没有展示 causal chain。
