Build It Better Design Plan

Transcription

1 Build It Better Design Plan Name: Objective Work as an agricultural engineer to design a model corral and alley way for loading cattle onto trucks for transportation. The goal of your design is to keep the animals calm and safe. Your group will be graded on the effectiveness, efficiency, and durability of your design. Research Research and record at least five design characteristics that your group will include in your model. Write the reason each characteristic was included. Design Characteristic Example: Curved Path for Cattle Reason for Inclusion Cattle prefer to return to where they came from. Design Drawing Sketch a design that incorporates all the design characteristics listed above. Label each design characteristic. Use arrows to indicate the direction cattle will move.

2 Build It Better Design Plan (continued) Teacher Approval Each group s drawing must be approved by your teacher before starting construction. Present your design drawing to your teacher. Be sure to identify and describe the design characteristics. Once approved, have your teacher initial here: Construction Use your design drawing to construct a three-dimensional model. Label design characteristics and include measurements for all sides. Reflection 1. List the materials required to construct your design model. You may use any of the materials provided in class or bring materials from home. 2. Describe, in detail, the procedure your group used to construct the model. The procedure must include at least ten steps. a. b. c. d. e. f. g. h. i. j. 3. List any modifications required to create an effective, efficient, and durable design.

3 Build It Better Design Plan (continued) 4. How will you motivate the cattle to move through the chute? 5. What is your favorite feature of your design? Why? 6. What aspect of your design could be improved? How? 7. Is your design effective, efficient, and durable? Provide at least one example of how your model meets each of these specifications. Effective: Successful in producing a desired or intended result. Efficient: Achieving maximum productivity with minimum wasted effort or expense. Durable: Able to withstand wear, pressure, or damage.

5 Build It Better Design Grading Rubric Evaluator s Name: Designers: Circle the appropriate description for the project you are evaluating. 10 Points 8 Points 6 Points 4 Points Information Gathering taken from several sources in a systematic manner. taken from a couple of sources in a systematic manner. taken from a couple of sources, but not systematically. Information taken from only one source and/ or information not accurate. Design Drawing Plan is neat, detailed, and all design Plan is detailed and most design Plan lacks precision but most design Plan lacks precision and is inadequately Construction Great care taken in construction process so that the structure is neat, attractive, and follows plans accurately. Construction was careful and accurate, but some details could have been refined for a more attractive product. Construction differs from the original plan and some details could have been refined for a more attractive product. Construction appears careless and haphazard. Many details need refinement for a strong or attractive product. Design Plan Worksheet Provides a complete record of planning, construction, modifications, and reflections about the process. Provides a complete record of planning, Provides some detail about planning, Provides very little detail about several aspects of the planning, Total points: Comments:
