1. 3 Science and Technology are interrelated

Technology involves processes, devices, and people § Technology – use of knowledge to create processes or tools that change the way things are done § Systems for producing things § Devices or products § Involves the act of making or doing § Techniques and methods of use § Changes with time and new discoveries

Technology Design Process: § 1. identify the problem/need § 2. research problem and existing technology § 3. develop standards § 4. work within limits

Prototype § Prototype- working model used to see if the new technology will work and meet standards § Used to make sure no unexpected problems occur Why might a designer research a problem after making a prototype? The designer will troubleshoot, find any problems, fix them, and develop the full technology

Factors to consider when designing technology § CONSTRAINT § Limits on how technology can be designed § CRITERIA § Standards by which people judge a new technology

Categories of Technology § Medical – medicines, vaccine, devices § Agricultural – farming techniques, genetic engineering, § § § food distribution Energy and power – house wiring, power lines, electrical power plants Information and communications- computers, internet, telephone Transportation – road planning, cars, fuel-efficient engines Manufacturing – assembly lines Construction – architect design, construction machines, improvement on materials

Technology creates new opportunities to advance science § Technology allows scientists to make new, detailed, and accurate observations § Optical microscope – use light to form magnified image § SEM (scanning electron microscope) – uses electrons to for images, shows depth, able to see parts of an atom § AFM (atomic force microscope) – even greater magnification

Many advances in technology depends on advances in science § Animals as a technology inspiration: § 1. spiders walk on walls – make new, stronger glue § 2. sharkskin – new swimsuit fabrics that allow swimmer to move faster in water § 3. penguins way of swimming – replaced propellers of a motor boat

New Technologies have both risks and benefits § Risk – undesired effect, sometimes preventable but other times noticeable for a long time § Hollywood built a new bus transportation for everyone to use
