1. Notes Notebook: Name of a Method of Modeling, Short Description, Example Modeling

2. Learning Objectives • You will be able to recognize different ways of modeling. • You will create several graphical models of a given challenge.

3. Modeling • The act of representing designs or ideas in various forms in order to present or evaluate a design. • Concept Modeling • Graphical Modeling • Mathematical Modeling • Computer Modeling • Physical Modeling

4. Concept Modeling Listing or mapping the concepts involved in a design or process under investigation. • Example: Designing a Theme Park • Perhaps the first step to designing a theme park would be to create a list of the rides, attractions, and facilities that would be included in the design. • Easy access to major transportation system • Circular pattern of attractions • A theme (fairy tale, nations, sports) • Access to Emergency Medical facilities • Etc.

5. Concept Modeling • Example: Solve Global Warming

6. Graphical Modeling Representing information in the form of charts, graphs, maps, or geometric figures. • Example: Mapping the Ocean Floor

7. Graphical Modeling • Example: Sketches and Drawings

8. Graphical Modeling • Example: Graphs and Charts

9. Mathematical Modeling Using mathematical equations or geometric representations to predict or model a phenomenon or behavior. • Example: Designing a Beverage Container • Design a cylindrical beverage container to hold a given volume of liquid. V = π r2h

10. Mathematical Modeling • Example: Garbage Production in York County

11. Computer Modeling Using a computer and software to create a representation of an object or concept. • Can include • 3D modeling of parts • Modeling of structures for structural analysis • Modeling of circuits for circuit analysis • Modeling of chemical processes to check reactions and byproducts, etc.

12. Computer Modeling • Example: Soap Dish Design (in Inventor)

13. Computer Modeling • Example: Structural Frame Model

14. Computer Modeling • Example: Circuit Model

15. Physical Modeling Using physical materials to create a representation of an object or concept. • Mock-up: An appearance model used to present the general concept of a design • Scale Model: A representation of a design that is either larger or smaller than the actual model • Prototype: A working model of the actual design

16. Physical Model • Example: Scale Model

17. Physical Model • Example: Mock-up Key Chain Automatic Dog Feeder

18. Physical Model • Example: Prototype Cross Country Training Ski Portable Wind Turbine Visible Toaster

19. Modeling Activity: Physical and Graphical • Procedure • In this activity you will be given six wooden cubes. • You will brainstorm as many part combinations as possible using only three of those cubes. You will sketch your part combinations on the isometric grid paper provided. Make sure that you date and sign each combination that you document. • You will perform the same process using just four cubes, then with five cubes, and finally with six cubes. • It is important that you identify as many combinations as possible for each set of cubes. The goal is to come up with more combinations than your classmates. • Your sketches will be used to help you determine what parts you would want for your cube and how they would fit together. • You will present your findings to the teacher for review.
