    17 Apr 2017 | Modeling Scenarios | Contributor(s):: Brian Winkel

    We offer an experiment in which data is collected to ascertain a parameter in the differential equation formulation of Torricelli's Law for water flow from a container.

  10. 1-073-S-WaterExitBottle

    17 Apr 2017 | Modeling Scenarios | Contributor(s):: Brian Winkel

    We offer an experiment in which data is collected to ascertain a parameter in the differential equation formulation of Torricelli's Law for water flow out of a cylindrical container.

  11. 6-023-S-DroneHeadingHome

    13 Apr 2017 | Modeling Scenarios | Contributor(s):: Richard Spindler

    You just received a new long-range helicopter drone for your birthday! After a little practice, you try a long-range test of it by having it carry a small package to your home. A friend volunteers to take it 5 miles east of your home with the goal of flying directly back to your home. So you...
