Quarky & Quaysoo's Turbo Science was an educational computer game developed by Jeff Tunnell Productions and published by Sierra On-Line for MS-DOS in early 1993. It was designed to teach scientific concepts to children.
The game centered around Quarky and Quaysoo O'Gandi, two space "elfs" that were green and yellow respectively. With the help of the player they raced through a town in vehicles ranging from cars to jet packs. To purchase vehicles, the player answered questions relating to science at stops along the way.
Each stop had a theme: the construction site was simple machines, Clown College was chemistry, etc.
There were three opposing teams: two tough street fighters, a pair of alien siblings, and a know-it-all named Odessa King. The game also featured an information book that ran over one-hundred pages long and taught science topics such as optics (via a run-in with the light police) and energy (with the help of Sheik Oil Slick).
