Boyle's, Charles's, and Gay-Lussac's gas laws are practiced through a two-page worksheet that pairs a variable-labeling table with a pressure-versus-volume data set students plot and interpret on their own graph. Students identify which variable belongs on each axis, explain why the pressure-volume product stays constant, and state whether the relationship is directly or inversely proportional. A second page applies the same three laws to real-world scenarios — a helium balloon that shrinks in cold weather and expands indoors, and an over-inflated car tire driven on a hot day — asking students to identify the governing law and sketch the balloon's particle behavior. A complete answer key with a filled-in table, a labeled graph, and full written explanations follows on pages 3 and 4.
