Slide 1 - What is Technology?
Slide 2 - What is Technology? Technology is comprised of the products and processes created by engineers to meet our needs and wants.
Slide 3 - 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”
Slide 4 - How Does Technology Address Human Needs and Wants? Transportation Technology Medical Manufacturing & Construction Bio-Related and Agriculture Nanotechnology Information Communication Energy and Power Environmental
Slide 5 - Information Technology Information Technology allows us to send signals around the world. Examples: Television, Internet, satellite, GPS, cell phones
Slide 6 - Impacts of Information Technology INTERNET –Information is stored for easy access INTERNET – Harder to distinguish between reliable and unreliable sources
Slide 7 - Communication Technology Communication Technology is giving or exchanging information. Examples: Magazines, DVDs, photography, video games
Slide 8 - Impacts of Communication Technology DIGITAL CAMERAS Allow you to edit and print only the pictures you like COMPUTERS, PRINTERS, & DIGITAL CAMERAS Make forgery and plagiarism easier
Slide 9 - Bio-related and Agricultural Technology Biotechnology transforms living things into products or new forms of life. Examples: Genetic engineering, bionics Agricultural Technology produces plants and animals for food, fiber, and fuel. Examples: Irrigation, food preservation, weed and insect control Both deal with living things: Plants, animals, and people DNA Replication image from the Human Genome Project
Slide 10 - Impacts of Bio-Related Technology HEALTH – Improves quality of life, vitamins, vaccines, medications HEALTH – Side effects of some medications – nausea, shortness of breath, etc.
Slide 11 - Impacts of Agricultural Technology FERTILIZERS– can make plants produce more food per acre FERTILIZERS– have found their way into ground water, polluting good drinking water
Slide 12 - Medical Technology Medical Technology creates tools to treat disease and injury. Examples: Lasers, prostheses, ultrasound, medications
Slide 13 - Impacts of Medical Technology X-RAYS – Make it easier to diagnose injuries X-RAYS – Too many x-rays can cause cancer.
Slide 14 - Environmental Technology Environmental Technology creates tools to minimize the effect of technology on the development of living things. Examples: Hybrid vehicles, conservation, waste management (recycling)
Slide 15 - Impacts of Environmental Technology RECYCLING – Improves water and air quality RECYCLING – Disposal of garbage is more complicated and time consuming
Slide 16 - Production Technology Production Technology is the manufacturing of physical goods on an assembly line and the construction of structures on a job site.
Slide 17 - Manufacturing changes natural or synthetic materials into usable products. Examples: Clothing, vehicles, food Construction Technology builds structures that support loads and protect us from the environment. Examples: House, bridge, roads Production Technology
Slide 18 - Impacts of Production Technology New products help to make our life easier and increase leisure time Many industries use materials that can harm the environment Provides shelter, improves roads, creates employment opportunities Noise and debris, traffic problems, accidents and injuries
Slide 19 - The development of materials with outstanding combinations of mechanical, chemical, and electrical properties that make other advances possible. Examples: Mosquito repellent clothing, artificial skin grafts for burn victims, advanced building materials such as composite decking Materials Technology
Slide 20 - Impacts of Materials Technology NEW MATERIALS – able to reuse recycled materials to help the environment NEW MATERIALS – don’t know how the materials will behave over long periods of time.
Slide 21 - Transportation Technology Transportation Technology Provides a way for people, animals, products, and materials to be moved from one place to the next. Examples: Flight – Airplane, rocket, space shuttle Land – Train, subway, automobile, bicycle Water – Commercial, cruise ships Non-vehicle – Conveyor belts, pipelines
Slide 22 - Impacts of Transportation Technology Traveling long distances faster Accidents
Slide 23 - Energy and Power Technology Energy is the ability or capacity to do work. Examples: Chemical Energy  Gasoline Mechanical Energy  Motion Thermal Energy  Steam Electrical Energy  Electricity Radiant Energy  Light
Slide 24 - Energy and Power Technology Power is the rate at which energy is transformed from one form to another. Examples: Electrical power – provides light and operates motors Mechanical power – moves automobiles, trains, and airplanes Fluid power – uses fluids to produce motion Hydraulic – uses a liquid Pneumatic – uses a gas
Slide 25 - Impacts of Energy and Power Technology Without energy and power, most technologies would not exist or work Overuse of nonrenewable resources
Slide 26 - Nanotechnology Nanotechnology is manipulating materials on an atomic or molecular level. Examples: Sensors, Nanobot, molecular manufacturing
Slide 27 - Impacts of Nanotechnology Continuously sense and adjust medical treatment Impede privacy
