In Fall of Javert, students use quadratic functions about how objects fall to determine how high Javert’s bridge must have been and explore this even further in two project tasks, Upholding the Law (of Gravity) and Actually, It is Rocket Science.
Current Version: April 22, 2014
At the end of the popular musical Les Misérables, a dejected Inspector Javert throws himself off a bridge and into the River Seine. As he falls, he sings...and sings...and sings. According to the song, he falls for a full eight seconds!
In the launch activity of Fall of Javert, students use quadratic functions and information about how objects fall (i.e. gravity) to determine how high Javert’s bridge must have been. Then, they use linear functions to figure out how fast he was traveling when he hit the water, and whether we can believe anything that Broadway says…er, sings.
Students explore this even further in the project tasks, and can choose between two topics. In one task, students where Javert’s fall would have made sense, but they have to think beyond the bounds of Earth to do it! In another, they construct and launch stomp rockets, use what they learned in the launch activity to figure out the altitude a stomp rocket can reach.
