  1. 1-025-S-MixingItUp

    04 Jun 2015 | Modeling Scenarios | Contributor(s): Brian Winkel

    Students build three different models for levels of salt in a tank of water and at each stage the level of complexity increases with attention to nuances necessary for success.

    01 Jun 2015 | Modeling Scenarios | Contributor(s): Brian Winkel

    SPANISH LANGUAGE VERSION  We have placed in Supporting Docs both Student and Teacher Version (LaTeX and PDF Versions) with a Spanish LaTeX Class file, SIMIODE-SPANISH.cls. Names will be x-y-S-Title-StudentVersion-Spanish and x-y--T-Title-TeacherVersion-Spanish

  7. 1-030-Text-S-RandomPerturbation

    05 Mar 2020 | Technique Narratives | Contributor(s): Reza Ahangar

    After a brief historical view of this problem, we will demonstrate the derivation of first order linear differential equations with random perturbations. Students in their semester research project under a course “special topics” or “independent study” will learn a past...

  8. 1-030-Text-T-RandomPerturbation

    05 Mar 2020 | Technique Narratives | Contributor(s): Reza Ahangar

    After a brief historical view of this problem, we will demonstrate the derivation of first order linear differential equations with random perturbations. Students in their semester research project under a course “special topics” or “independent study” will learn a past...

  9. 1-031-S-CoolIt

    02 Jun 2015 | Modeling Scenarios | Contributor(s): Brian Winkel

    We offer data on the temperature of water in a beaker which resides in a room of constant temperature and also in an environment of nonconstant temperature. Students are encouraged to consider both empirical and analytic modeling approaches. We offer additional data sets in Excel spreadsheets...

  10. 1-032-S-DigoxinElimination

    17 Aug 2018 | Modeling Scenarios | Contributor(s): Therese Shelton

    We model the concentration of digoxin eliminated from the human body at a rate proportional to the concentration. This is a ``first-order reaction'' in the language of pharmacokinetics -- the study of how drugs move in the body. This activity can be used to introduce compartmentalized...

  11. 1-032-S-WordPropagation

    07 Apr 2016 | Modeling Scenarios | Contributor(s): Rachelle DeCoste, Rachel Bayless

    This activity is a gentle introduction to modeling via differential equations. The students will model the rate at which the word jumbo has propagated through English language texts over time.

    22 Jun 2016 | Modeling Scenarios | Contributor(s): Troy Henderson

  13. 1-034-S-FishMixing

    24 Dec 2015 | Modeling Scenarios | Contributor(s): Eric Sullivan, Elizabeth Anne Carlson

    This activity gives students a chance to build the underlying differential equation and/or difference equation for a mixing problem using tangible objects (fish) and a student-designed restocking and fishing plan in a lake. The mixture is of two species of fish, one being the current sole...

    03 Jun 2016 | Modeling Scenarios | Contributor(s): John Thomas Sieben

  15. 1-037-S-CommonColdSpread

    30 Nov 2016 | Modeling Scenarios | Contributor(s): Richard Corban Harwood

    This modeling scenario guides students to simulate and investigate the spread of the common cold in a residence hall. An example floor plan is given, but the reader is encouraged to use a more relevant example. In groups, students run repeated simulations, collect data, derive a differential...

  20. 1-042-S-Kool-Aid

    26 Apr 2017 | Modeling Scenarios | Contributor(s): Kristin Burney, Lydia Kennedy, Audrey Malagon

    We model the amount of drink powder in a second tank of a two tank flow system.
