  10. 1-111-S-SpreadOfInformation

    02 Sep 2019 | Modeling Scenarios | Contributor(s): Jeff Pettit

    Students perform experiments to model spread of information within a population. Students collect data, determine essential components and parameters and build a mathematical model which can be compared to predicted data, measured data, and modeled data. Part 3 can require students to move from...

  11. 1-092-T-DashItAll

    01 Sep 2019 | Modeling Scenarios | Contributor(s): Kurt Bryan

    This project uses very basic physics, Newton's Second Law of Motion, to model the motion of a sprinter running down a track. The model is driven by data from the world record race of Usain Bolt in the 2008 Beijing Olympic games. In particular, we derive the classic Hill-Keller model for a...
