  1. 1.3 Science and Technology are interrelated

  2. 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

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

  4. 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

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

  6. 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

  7. 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

  8. 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

  9. New Technologies have both risks and benefits • Risk – undesired effect, sometimes preventable but other times not noticeable for a long time • Hollywood built a new bus transportation for everyone to use
