Unit 1: What Is Technology?

Technology The study and management of the human made world. *Based on human needs and wants. People have to need it people have to want it in order for technology to happen.

Need - something we require to survive - essential to life. Examples of human needs: Basic shelter Basic clothing Water Food

Want - something we desire, but is NOT required for survival. It is not essential to life. Examples of human wants: Fancy car Xbox Cell Phones Designer clothing

Technology Study of the humanmade world Deals with what can be Science Study of the natural world Deals with what is

Information Technology allows us to access, create, store, and manipulate data. 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 is the giving or exchanging of information. Examples: Magazines, DVDs, photography, video games

Impacts of Communication Technology POSITIVE IMPACTS Access information and contact people faster and easier. NEGATIVE IMPACTS The digital world has made forgery and plagiarism easier.

Biotechnology transforms living things into products or new forms of life. *deals with living things. Examples: Genetic engineering Bionics DNA Replication image from the Human Genome Project

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.

Agricultural Technology - produces plants and animals for food, fiber, and fuel. Examples: Irrigation, food preservation, weed and insect control

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 *weeds and insects could mutate and become resistant!

Medical Technology creates tools to treat disease and injury. Examples: Lasers, prosthetics, ultrasound, medications

Impacts of Medical Technology POSITIVE IMPACTS X-RAYS Make it easier to diagnose injuries NEGATIVE IMPACTS Radiation Too much can damage the body.

Environmental Technology creates ways to minimize harmful effects technology has on Earth. Examples: Hybrid vehicles, conservation, waste management (recycling)

Impacts of Environmental Technology POSITIVE IMPACTS RECYCLING Improves water and air quality NEGATIVE IMPACTS RECYCLING Disposal of garbage is more complicated and time consuming

Manufacturing technology changes natural or synthetic materials into usable products. EXAMPLES: CLOTHING, VEHICLES, FOOD, LUMBER, STEEL

IMPACTS OF MANUFACTURING TECHNOLOGY POSITIVE IMPACTS Make new products quicker and faster! NEGATIVE IMPACTS Many industries use materials that can harm the environment

CONSTRUCTION TECHNOLOGY Construction Technology - builds structures that support loads and protect us from the environment. Examples: Houses, bridges, roads, dams

Impacts of Construction Technology POSITIVE IMPACTS NEGATIVE IMPACTS CONSTRUCTION CONSTRUCTION Provides shelter, improves roads, creates employment opportunities Noise and debris, traffic problems, accidents and injuries

Materials Technology - The development of materials with outstanding combinations 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 NEW MATERIALS able to reuse recycled materials to help the environment NEGATIVE IMPACTS NEW MATERIALS don t know how the materials will behave over long periods of time. The B-2 bomber uses high tech composites to achieve its stealth capabilities

Transportation Technology Provides a way for people and goods to move from one location to another. Examples: Flight airplane, rocket, space shuttle Land train, subway, automobile, bicycle Water boats, cruise ships Non vehicle conveyor belts, pipelines

Impacts of Transportation Technology POSITIVE IMPACTS Traveling long distances faster NEGATIVE IMPACTS Accidents, harms environment

Energy Technology Energy is the ability or capacity to do work. Examples: Chemical Energy Mechanical Energy Thermal Energy Electrical Energy Radiant Energy Gasoline Motion Steam, Solar Electricity Light, Heat

Power Technology Power is the rate at which energy is transformed from one form to another. (Potential to kinetic). 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 *Once we have potential energy, we put it to use by converting it into kinetic energy. *We have power when we can apply kinetic energy over a period of time to do work.

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 manipulating materials on an atomic or molecular level. Examples: Sensors, stain free clothing, wrinkle free pants, nanobots, molecular manufacturing

Impacts of Nanotechnology POSITIVE IMPACTS IMPLANTED SENSORS Smaller, faster electronics!! NEGATIVE IMPACTS IMPLANTED SENSORS A lot of unknown, hard to understand/explore.
