Technology
Standards • SPI 0707.T/E.2 –Evaluate a protocol to determine if the engineering design process was successfully applied. SPI 0707.T/E.3 -Distinguish between the intended benefits and the unintended consequences of a new technology. SPI 0707.T/E.4 Differentiate between adaptive and assistive engineered products (e.g., food, biofuels, medicines, integrated pest management)
Technology and Society Technology provides solutions for many types of social, political, and economic needs. Intended Benefit An intended benefit is the positive purpose for which a technology is designed to be used. Unintended Consequences Unintended consequences are uses or results that engineers do not purposely include in the design of products. An unintended consequence can be beneficial.
Bioengineering The application of engineering to living things, such as humans and plants, is called bioengineering. Bioengineered technologies can be classified as either assistive or adaptive.
Assistive Technologies Assistive technologies are developed to… help organisms without changing them Assist = Help Temporary Examples: Eyeglasses Wheelchairs Hearing Aids Crutches Airplane Hairbrush Doorstop
Adaptive Technologies Adaptive bioengineered products… change the living organism Adapt = Change Permanent Artificial heart Knee replacement Lasik eye surgery Genetically Modified Organisms (GMOs) Ethanol (added to gasoline)
