  1. 1-145-S-FastPitch

    23 Jan 2022 | | Contributor(s):: Erich McAlister

    Pitch velocity is one of the most fascinating statistics in baseball, as documented in the 2015 documentary Fastball. Modern measurements of pitch velocity are taken as the maximum velocity achieved at any point between the pitcher's hand and home plate. However, the velocity of the ball...

  2. 1-142-S-WaterBottles

    04 Aug 2021 | | Contributor(s):: Allison Leigh Lewis

    This modeling scenario guides a student familiar with single ordinary differential equation (ODE) models towards the development of a more complex system of two ODEs for describing the evolution of tumor growth over time. Students should have prior experience with solving ODEs using the separable...

  5. 1-150-S-CancerTherapy

    03 Aug 2021 | | Contributor(s):: Maila Hallare, Iordanka Panayotova

    This activity builds upon elementary models on population growth. In particular, we compare two different treatment models of cancer therapy where in one, surgery happens before therapy and in the other, surgery happens after therapy.Activities will help students appreciate the importance of...

  6. 1-119-S-DairyFarming

    20 Sep 2020 | | Contributor(s):: Rob Krueger

    A simple first order population growth model is presented.  The challenge is to produce a final differential equation which is the result of the difference or ratio of birth and death rates. This ratio is not immediately intuitive.

  7. 9-002-S-GroundWaterFlow

    31 Aug 2020 | | Contributor(s):: Jeremy Cristman, Kenneth Luther, Michael Karls

    The goals of this project are to compare a conceptual one-dimensional groundwater flow model to observations made in a laboratory setting, and to discuss the differences. We derive the initial groundwater flow equation, and guide students through a solution. We describe the laboratory set up and...

  8. 2020-Tiffany, Patrice Geary - Remote Teaching Module - Separation of Variables

    21 Jul 2020 | | Contributor(s):: Patrice Geary Tiffany

    This module uses the scenario:  Ebola Outbreak in West Africa to introduce and apply the technique of separation of variables.   The students first have a warm up to give them background on the scenario, they review topics they need to know for the module, they start the...

  9. 1-136-S-MarriageAge

    11 Jun 2020 | | Contributor(s):: Tracy Weyand

    Students will build and analyze a model of the fraction of people who are married (for the first time) by a certain age. This model comes from a paper by Hernes and, in this project, is compared to another model used by Coale.These models are first-order ordinary differential equations (which...

  12. 1-128-S-RocketFlight

    04 Jun 2020 | | Contributor(s):: Brian Winkel

    We offer an opportunity to build a mathematical model using Newton's Second Law of Motion and a Free Body Diagram to analyze the forces acting on the rocket of changing mass in its upward flight under power and then without power followed by its fall to earth.

  13. 1-111-S-SpreadOfInformation

    02 Sep 2019 | | 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...

  14. 1-001d-S-HotelPopulationDecay

    03 Jul 2019 | | Contributor(s):: Dina Yagodich

    We offer students an opportunity to create a simulation model a hotel population with clients checking in and checking out according to two different disciplines as well as a number of different starting populations in the hotel.

  15. 2018-Schneebeli,Hans R. - Modeling Falling Bodies

    01 Mar 2018 | | Contributor(s):: Hans Rudolf Schneebeli
