Lesson 2 Technology Design and Innovation Vocabulary Technology literate, system, models, modeling, resource, requirement, trade-off, optimization, process, control, feedback Technology Literate Understand Technology Identify a technology you understand Technology is created to meet human needs If you are technology literate you understand how processes work and how products work , and understand that the laws of nature limit what technology can do. Systems Key ideas set fields of study apart • Geometry is different than Algebra Key ideas for technology involve systems • Systems are interrelated parts that work together to produce a desired result. Example: • Schools (teachers, students, text books) Tractor (engine, wheels, and plow) Describe a system, what are the parts? Models • Represent a system, process, product, structure or environment • Can be graphic (drawing) • Physical (scale model) Ex: toy car • Virtual (computer game) • Mathematical (graph, chart) Models etc… • Represent, analyze, predict, and explain the performance of a device or system • Often built before final product is produced Model of building for architect Identify a model in the real world Resources • Any type of supply, service, or support Seven types: 1) People 2) Capital (money) 3) Time 4) Information 5) Energy 6) Tools 7) machines Part 2 of Lesson 2 IF…. If you created a new technology that used the sun to make and receive texts what would your resources be for the project? Requirements • Define the performance of a system – New car design • • • • How quickly should it accelerate? How fuel efficient must it be? How should information be displayed to the driver? How much room is required for the driver? Trade-Offs • Technologists who develop products often cannot include everything they want in their design due to costs of materials • They have give up one option in order to gain a more realistic option – A tire that offers better traction might be better performing for a car design but the manufacture has to make a trade-off when choosing the brand, costs, and warranty option for the tire when considering the total costs for the customer.
