What is Technology? - Westerville City School District

What is Technology? Introduction 2011 Project Lead The Way, Inc. What is Technology? What is Technology? Technology is comprised of the products and processes created by engineers to meet our 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 How Does Technology Address Human Needs and Wants? Information Communication Bio-Related and Agriculture

Medical Environmental Technology Manufacturing & Construction Transportation Energy and

Power Nanotechnology Information Technology Information Technology allows us to send signals around the world. Examples: Television, Internet, satellite, GPS, cell phones Impacts of Information Technology POSITIVE

IMPACTS INTERNET Information is stored for easy access NEGATIVE IMPACTS INTERNET Harder to distinguish between reliable and

unreliable sources Communication Technology Communication Technology is giving or exchanging information. Examples: Magazines, DVDs, photography, video games Impacts of Communication Technology POSITIVE IMPACTS NEGATIVE IMPACTS DIGITAL CAMERAS Allow

you to edit and print only the pictures you like COMPUTERS, PRINTERS, & DIGITAL CAMERAS Make forgery and plagiarism easier Bio-related and Agricultural Technology

DNA Replication image from the Human Genome Project 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 Impacts of Bio-Related Technology POSITIVE IMPACTS HEALTH Improves quality of life, vitamins, vaccines,

medications NEGATIVE IMPACTS HEALTH Side effects of some medications nausea, shortness of breath, etc. Impacts of Agricultural Technology

POSITIVE IMPACTS FERTILIZERS can make plants produce more food per acre NEGATIVE IMPACTS FERTILIZERS have found their way into ground water, polluting good drinking water Medical Technology

Medical Technology creates tools to treat disease and injury. Examples: Lasers, prostheses, ultrasound, medications Impacts of Medical Technology POSITIVE IMPACTS X-RAYS Make it easier to diagnose injuries

NEGATIVE IMPACTS X-RAYS Too many x-rays can cause cancer. 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)

Impacts of Environmental Technology POSITIVE IMPACTS NEGATIVE IMPACTS RECYCLING Improves water and air quality RECYCLING

Disposal of garbage is more complicated and time consuming Production Technology Production Technology is the manufacturing of physical goods on an assembly line and the construction of structures on a job site. Production Technology Construction

Manufacturing changes natural or Technology builds synthetic materials structures that support loads and protect us into usable from the environment. products. Examples: House, Examples: Clothing, vehicles, bridge, roads food

Impacts of Production Technology POSITIVE IMPACTS MANUFACTURING New products help to make our life easier and increase leisure time CONSTRUCTION Provides shelter, improves roads, creates employment opportunities

NEGATIVE IMPACTS MANUFACTURING Many industries use materials that can harm the environment CONSTRUCTION Noise and debris, traffic problems, accidents and injuries

Materials Technology 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

Impacts of Materials Technology POSITIVE IMPACTS NEGATIVE IMPACTS NEW MATERIALS able to reuse recycled materials to help the environment NEW MATERIALS

dont know how the materials will behave over long periods of time. 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 Impacts of Transportation Technology POSITIVE IMPACTS Traveling long distances faster

NEGATIVE IMPACTS Accidents 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

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

Impacts of Energy and Power Technology POSITIVE IMPACTS Without energy and power, most technologies would not exist or work NEGATIVE IMPACTS Overuse of nonrenewable

resources Nanotechnology Nanotechnology is manipulating materials on an atomic or molecular level. Examples: Sensors, Nanobot, molecular manufacturing Impacts of Nanotechnology POSITIVE IMPACTS IMPLANTED SENSORS Continuously sense and

adjust medical treatment NEGATIVE IMPACTS IMPLANTED SENSORS Impede privacy Image Resources Microsoft, Inc. (2008). Clip Art.
