The Engineering Design Process
The application of science for practical purposes
What is technology?
What is a trade-off?
A group of interacting parts that work together to do a job
What is a system?
Examples of how living organisms are used as technology
By this process, people identify a need and then look for ways to meet that need.
What is the engineering design process?
What is a risk-benefit analysis?
A system where energy can flow into and out of the system, but matter cannot enter or leave
What is a closed system?
made up of two or more types of materials combined together
What are composites?
The process of emphasizing traits that occur naturally
What is selective breeding?
The application of science and math to solve real-life problems
What is engineering?
A table used to compare the features of multiple items
The scientific study of systems, including the parts of systems and the ways the parts interact
What is a systems theory?
The characteristics that indicate which materials are chosen
What are chemical and physical properties?
Technology that allows traits to be changed by modifying the DNA inside a living cell
Skills needed for engineering design
What is thinking creatively, thinking methodically, using math and models, using technology, and using science?
An evaluation of the materials and energy used for the manufacture, transportation, sale, use, and disposal of a product
What is a life cycle analysis?
A mechanism for regulating a system so that the system works efficiently
What is a control?
The limits of certain materials
What is availability, cost, and degree of hazard?
The imitation of living organisms to create technological products
What is biomimicry?
The description of different effects for a new technology
What is expected & favorable, expected & unfavorable, unexpected & favorable, and unexpected & unfavorable?
What is a positive feedback loop?
These do not fit in any of the usual categories, things like aerogels and nanomolecules
What are exotic materials?
The design world
What includes all the parts of the environment that were made by people? within the natural world
