Variables & Fair Tests: Full Lesson Pack

A complete, ready-to-teach scientific-practices lesson pack built around a paper-airplane investigation. Students identify independent, dependent, and controlled variables; distinguish a fair test from a flawed test; and explain how changing one factor at a time makes evidence interpretable. The lesson teaches the structure of a fair test before students plan and evaluate an investigation.
