Description:

Is it possible for a human to ride a bicycle at the speed of 80 miles per hour? This riddle asks students how such a feat could be accomplished. On a clue page, students read about and view a brief video clip of two boys experimenting to see if a certain combination of gears can help them bike faster. When students select the correct answer from the riddle's three answer choices, a video clip plays about a unique kind of aerodynamic bicycle. A cyclist talks about the special design features--the bike is covered and the rider sits in a reclining position--that reduce wind resistance and enable cyclists to reach speeds greater than 80 miles per hour.
