What is Technology?
Technology Technology is the process by which humans modify nature to meet their needs and wants.
Technology vs. Science Technology –Study of our human- made world –Deals with “what can be” Science –Study of our natural world –Deals with “what is”
Technology vs. Science continued Technology –Made up of sub-categories: Information Communication Bio-related and Agriculture Medical Environmental Production –Manufacturing –Construction Transportation Energy and Power Science Made up of sub- categories: Earth Science Biology Chemistry Physics Astronomy Other specialty areas –Quantum Physics –Computer Science
Needs vs. Wants Technology addresses human needs and wants What are human needs? PHYSICAL NEEDS: Basic shelter Basic clothing Can you think of more? BIOLOGICAL NEEDS: Water Food Can you think of more? PSYCHOLOGICAL NEEDS: Family Friends Can you think of more?
Needs vs. Wants continued Technology addresses human needs and wants What are human wants? PHYSICAL WANTS: Nice house Nice car Nice clothes Can you think of more? BIOLOGICAL WANTS: Fresh water Fancy food Healthy living Can you think of more? PSYCHOLOGICAL WANTS: Talk with family See friends Entertainment Can you think of more?
How does Technology address human needs and wants? Information Communication Bio-Related and Agricultural - Manufacturing - Construction Transportation Technology Production Energy and Power Medical Environmental Through the use of these technologies, often the meeting of human needs and wants is accomplished.
Information Technology Information Technology is the process of gathering and storing data to be used in various forms: It has: –Streamlined access to vast sources of information –Allows us to produce more accurate forms of communication –Expanded resource choices –Enabled us to retrieve data in seconds
Examples of Information Technology Data collected on paper Data stored in computers Data stored in books Data stored in equipment or machines
Impacts of Information Technology POSITIVE IMPACTS NEGATIVE IMPACTS COMPUTERS – use of a computer to gather data easily and store INTERNET – using to store information for easy access OBSCELENCE – machines need to be maintained and upgraded INTERNET – information is not always accurate or reliable
Communication Technology Communication Technology is a process of giving or exchanging information. It has: –Streamlined publishing techniques and allows us to produce more accurate drawings –Expanded entertainment choices –Enabled us to contact people thousands of miles away
Examples of Communication Technology Cell Phones Computer Aided Drafting Video Cassette Recordings Internet Radio Television Graphic Arts
Impacts of Communication Technology POSITIVE IMPACTS NEGATIVE IMPACTS CAD – using a computer to generate drawings INTERNET – a means of communicating quickly and inexpensively over long distances PAPER USAGE – people tend to create and print more documents INTERNET – people tend to misuse the internet for personal gain
Bio-related and Agricultural Technology Biotechnology is the application of the principles of biology to create commercial products or processes. Agricultural Technology is the application of processes that make it possible for food to be available year-round and to conserve resources. Both deal with living things –Plants –Animals –People
Examples of Bio-Related and Agricultural Technology Bio-related Technology Pharmaceuticals Artificial limbs Genetic engineering Hydroponics Imaging devices Cardiovascular devices Ethics Agriculture Food, Fiber, and Fuel Plant growth Machines Production of ag products Transportation of ag products Storage of ag products
Impacts of Bio-Related and Agricultural Technology POSITIVE IMPACTSNEGATIVE IMPACTS HEALTH – improves quality of life HEALTH – Drugs may cause birth defects ENVIRONMENTAL – can produce more food per acre than before ENVIRONMENTAL – Chemicals have found their way into ground water, polluting good drinking water
Medical Technology Medical Technology is the study of medicine through the use of and advances of technology, such as medical instruments and apparatus, imaging systems in medicine, and mammography. Related terms: Bio-medical Engineering Medical Innovations.
Examples of Medical Technology Medical instruments and apparatus Vaccine Pharmaceuticals Artificial limbs Imagining equipment Ergonomics – the study of designing equipment to fit the human body, its movement & thinking patterns
Impacts of Medical Technology POSITIVE IMPACTSNEGATIVE IMPACTS HEALTH – improves quality of life HEALTH – use of technology may hinder life span DISEASE – research on controlling diseases and their spread is shortened DISEASE – not all cultures embrace use of vaccines and thus disease spreads
Environmental Technology Environmental Technology is study of the processes to control waste, soil erosion, reducing sediment in waterways, conserving water, and improving water quality, artificial ecosystems, and the effects of technology on the development of flora and fauna.
Examples of Environmental Technology Conservation Synthetic energy Waste management
Impacts of Environmental Technology POSITIVE IMPACTSNEGATIVE IMPACTS EARTH – improves quality of life EARTH – use of technology may hinder life span of the planet DISEASE – reduces chance of disease from bad air and chemicals DISEASE – economical forces the need to make choices that are not easily made
Production Technology Production Technology is the manufacturing of physical goods on an assembly line and the construction of structures on a job site.
Manufacturing Manufacturing is the process of changing materials into usable products Natural (found in nature) or Synthetic (human-made) –Most takes place in factories on assembly lines –Results in items that are either consumer products (used up) or industrial products (used to make other products)
Examples of Manufacturing Technology Clothing Entertainment devices Automobiles Chemical products Lumber Steel Food
Construction Technology Construction Technology is the study of the processes to –Build a structure – made by joining parts to meet a certain need. Involves building a foundation, erecting the super structure, and finishing work. –Support the load – external force on an object. –Control the quality of construction using control systems.
Examples of Construction Technology Human-made structure: –Houses –High-rise buildings –Bridges –Roads –Dams –Schools
Impacts of Production Technology POSITIVE IMPACTSNEGATIVE IMPACTS MANUFACTURING – new products help to make our life easier and increase leisure time. MANUFACTURING – many industries use materials that can harm the environment. CONSTRUCTION – provides shelter, improves roads, creates employment opportunities. CONSTRUCTION – noise and debris, traffic problems, accidents & injuries
Transportation Technology Transportation Technology is the process by which people, animals, products, and materials are moved from one place to the next. –Flight –Land Transportation –Water Transportation –Goods Transportation
Examples of Transportation Technology Air –Airplane –Rocket –Space Shuttle –Helicopter Water –Commercial ships –Cruise Ships –Utility vessels Land –Train –Subway –Automobile –Bicycle Goods –Conveyor Belts –Robots –Trucks
Impacts of Transportation Technology POSITIVE IMPACTSNEGATIVE IMPACTS Commuting is easier; Traveling long distances faster Pollution Accidents Use of energy
Energy and Power Technology Energy is the ability to do work. Power is the rate at which energy is transformed from one form to another or as the rate at which work can be done. Technological products and systems need energy to function. The availability of energy often determines the development of technology.
Examples of Energy and Power Technology Chemical Energy –Gasoline Mechanical Energy –Motion Thermal Energy –Steam Power Measurement Examples: Horsepower Kilowatt Electrical Energy –Electricity Radiant Energy –Light Power System Examples: Turbines Portable generators
Impacts of Energy and Power Technology POSITIVE IMPACTSNEGATIVE IMPACTS Without energy and power, most technologies would not exist or work. The overuse of natural resources is a concern of many people.
