This paper describes the creation of a theme-based first quarter, of a two quarter sequence, general chemistry laboratory course following an argument driven inquiry format and employing specifications grading. The course contains four, two-week projects investigating the chemistry of a popular sports drink. The sugar content, dye concentration, buffering capacity, and the kinetics of dye decomposition are investigated for various flavors of Gatorade. Specifications grading is used to foster teamwork and to provide an opportunity for revision and resubmission of student work. A modified LCAS survey measured student perception of course content.
