    UNIT SUMMARY

    Unit 1………………Design Process
                   
                       Unit 1 is to introduce students to the broad field of engineering
                                                    and a design process that engineers use to develop innovative
                                                    solutions to real problems. Students become familiar with
                                                    the traditional big four disciplines of engineering and the extensive
                                                    array of career opportunities and engineering problems addressed
                                                    within each discipline. A design process is presented as a structured
                                                    method for approaching and developing solutions to a problem.
                                                    The art and skill of brainstorming is emphasized as students begin
                                                     to develop skill in graphically representing ideas through concept sketching.

    Unit 2………………Technical Sketching and Drawing              
                                    
     Unit 2 is for students to develop an understanding of the purpose and practice
                                                     of visual representations and communication within engineering
                                                     in the form of technical sketching and drawing. Students build skill and
                                                     gain experience in representing three-dimensional objects in two dimensions.
                                                     Students will create various technical representations used in visualization,
                                                     exploring, communicating, and documenting design ideas throughout
                                                     the design process, and they will understand the appropriate use of
                                                     specific drawing views (including isometric, oblique, perspective,
                                                     and orthographic projections). They progress from creating free hand
                                                     technical sketches using a pencil and paper to developing engineering
                                                     drawings according to accepted standards and practices that allow
                                                     for universal interpretation of their design.
            

    Unit 3………………Measurement and Statistics
                               
          Unit 3 is for students to become familiar with appropriate practices and the applications
                                                    of measurement (using both U. S. Customary and SI units) and statistics within
                                                    the discipline of engineering. Students will learn appropriate methods of making
                                                    and recording measurements, including the use of dial calipers, as they come
                                                    to understand the ideas of precision and accuracy of measurement and their
                                                    implications on engineering design. The concepts of descriptive and inferential
                                                    statistics are introduced as methods to mathematically represent information
                                                    and data and are applied in the design process to improve product design,
                                                    assess design solutions, and justify design decisions. Students are also provided
                                                    with practice in unit conversion and the use of measurement units as an aid in
                                                    solving practical problems involving quantities. A spreadsheet program is used
                                                    to store, manipulate, represent, and analyze data, thereby enhancing and extending
                                                    student application of these statistical concepts.

    Unit 4………………Modeling Skills
                             
            Unit 4 introduces students to a variety of modeling methods and formats used to represent
                                                    systems, components, processes, and other designs. Students are provided experience
                                                    in interpreting and creating multiple forms of models common to engineering as they
                                                    apply the design process to create a design solution. Students create graphical models
                                                    of design ideas using sketches and engineering drawings and create graphs and charts
                                                    to represent quantitative data. In this unit students are introduced to three-dimensional
                                                    computer modeling. They learn to represent simple objects in a virtual 3D environment
                                                    that allows for realistic interactions and animation. The modeling software is also used
                                                    to provide an efficient method of creating technical documentation of objects.
                                                   Students are provided the opportunity to create a physical model of a design
                                                   solution to be used for testing purposes. Mathematical modeling is introduced,
                                                   and students learn to find mathematical representations (in the form of linear functions)
                                                   to represent relationships discovered during the testing phase of the design process.


    Unit 5………………Geometry of Design
                     
               Unit 5 provides students the opportunities to apply two- and three- dimensional
                                           geometric concepts and knowledge to problem solving and engineering design.
                                           Fluency in these geometric concepts is essential in every phase of the design
                                           process as problems are defined, potential solutions are generated to meet
                                           physical constraints, alternate design solutions are compared and selected,
                                           final designs are documented, and specifications are developed. Geometric
                                           concepts are also important in the appropriate application of geometric
                                           and dimensional relationships and constraints for effective use of three-dimensional
                                           computer modeling environments that employ parametric design functionality.
                                           In this unit students use geometric concepts and physical properties to solve a
                                           wide variety of problems, progressing from computations of surface area, weight,
                                           or volume in order to provide cost estimates to the identification of materials
                                           based on physical property observations. Students will also use 3D computer
                                           models to compute physical properties that can be used in problem solving
                                           and creation of design solutions.

    Unit 6………………Reverse Engineering
                         
                Unit 6 exposes students to the application of engineering principles and practices to
                                                     reverse engineer a consumer product. Reverse engineering involves disassembling
                                                     and analyzing a product or system in order to understand and document the visual,
                                                     functional, and/or structural aspects of its design. In this unit students will have the
                                                     opportunity to assess all three aspects of a product’s design. Students will learn the
                                                     visual design elements and principles and their application in design. They will perform
                                                      a functional analysis to hypothesize the overall function and sequential operations
                                                     of the product’s component parts and assess the inputs and outputs of the process(es)
                                                     involved in the operation of the product. Students will physically disassemble the product
                                                     to document the constituent parts, their properties, and their interaction and operation.
                                                     After carefully documenting these aspects of the visual, functional, and structural aspects
                                                     of the product, students will assess the strengths and weaknesses of the product
                                                     and the manufacturing process by which it was produced.

    Unit 7………………Documentation
                     
                    Unit 7 enhances student basic knowledge of technical drawing representations learned earlier
                                                    in the course to include the creation of alternate (section and auxiliary) views and
                                                    appropriate dimensioning and annotation of technical drawings. Students will also
                                                    be introduced to the reality of variation in dimensional properties of manufactured products.
                                                   They will learn the appropriate use of dimensional tolerances and alternate dimensioning
                                                   methods to specify acceptable ranges of the physical properties in order to meet design
                                                   criteria. Students will apply this knowledge to create engineering working drawings that
                                                   document measurements collected during a reverse engineering process.
                                                   These skills will also allow students to effectively document a proposed new design.
                                                   Students will use 3D computer  modeling software to model the assembly of the
                                                   consumer product, as such a model
     can be used to replicate functional operation
                                                   and provide virtual testing of product design.


    Unit 8………………Advanced Computer Modeling

                             Unit 8 students learn advanced 3D computer modeling skills. These advanced skills
                                           include creating exploded and animated assembly views of multi-part products.
                                           Students will learn to use mathematical functions to represent relationships
                                           in dimensional properties of a modeled object within the 3D environment.
                                           Students will also develop and apply mathematical relationships to enforce
                                           appropriate dimensional and motion constraints. Students will reverse engineer
                                           and model a consumer product, providing appropriate parametric constraints
                                           to create a 3D model and realistic operation of the product.

    Unit 9………………Design Team
                                   
    Unit 9 allows for student collaboration within a team. Through the design process, the team will
                                                   experience shared decision-making as they work to solve a new design challenge.
                                                   They will reflect on the ethical responsibilities of engineers as they investigate different
                                                   materials manufacturing processes, and the short and long term impacts that
                                                   their decision-making may potentially have on society and on the world.


    Unit 10……………..Design Challenges   
                                   
    Unit 10 allows work within small collaborative teams, implement the design process, and use skill
                                                      and knowledge gained during the course to solve a culminating design challenge and
                                                      document and communicate their proposed solution.
