What is Technology?

What is Technology?:

What is Technology? Technology is comprised of the products and processes created by engineers to meet our needs and wants.

Science vs. Technology:

Science vs. Technology What’s the difference?


Science Knowledge about the natural world through observations and experimentation. The leaves are changing colors. The ball goes up in the air and then falls down.


Technology The application of knowledge to solve problems and make new inventions. Telephones are used for long distance communication. Knives are used to cut food into smaller pieces.

Can you tell the difference between science and technology?:

Can you tell the difference between science and technology? Shampoo keeps your hair clean. TECHNOLOGY

Can you tell the difference between science and technology?:

Can you tell the difference between science and technology? Grapes grow on vines. SCIENCE

How many can you name? :

How many can you name? Science Technology 1. 1. 2. 2. 3. 3. 4. 4. 5. 5.

Technology vs. Science:

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”


Science The goal of science is often to describe, explain, and predict relationships that occur naturally. In other words, science tries to explain objects and events. E.G., How do changes in the kind of soil affect how abundantly mushrooms grow?


Technology The goal of technology is to try and change the relationship that exists to achieve desirable results. In other words, technology tries to change objects and events. E.g., how can we stop mushrooms from growing ?

How Does Technology Address Human Needs and Wants?:

How Does Technology Address Human Needs and Wants? Transportation Technology Medical Manufacturing & Construction Bio-Related and Agriculture Nanotechnology Information Communication Energy and Power Environmental

Information Technology:

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

Impacts of Information Technology:

Impacts of Information Technology POSITIVE IMPACTS NEGATIVE IMPACTS INTERNET –Information is stored for easy access INTERNET – Harder to distinguish between reliable and unreliable sources

Communication Technology:

Communication Technology Communication Technology is giving or exchanging information. Examples: Magazines, DVDs, photography, video games

Impacts of Communication Technology:

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:

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

Impacts of Bio-Related Technology:

Impacts of Bio-Related Technology POSITIVE IMPACTS NEGATIVE IMPACTS HEALTH – Improves quality of life, vitamins, vaccines, medications HEALTH – Side effects of some medications – nausea, shortness of breath, etc.

Impacts of Agricultural Technology:

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

Medical Technology:

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

Impacts of Medical Technology:

Impacts of Medical Technology POSITIVE IMPACTS NEGATIVE IMPACTS X-RAYS – Make it easier to diagnose injuries X-RAYS – Too many x-rays can cause cancer.

Environmental Technology:

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:

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 Production Technology is the manufacturing of physical goods on an assembly line and the construction of structures on a job site.


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

Impacts of Production Technology:

Impacts of Production Technology POSITIVE IMPACTS NEGATIVE IMPACTS MANUFACTURING – MANUFACTURING – CONSTRUCTION – CONSTRUCTION – 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


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

Impacts of Materials Technology:

Impacts of Materials Technology POSITIVE IMPACTS NEGATIVE IMPACTS 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.

Transportation Technology:

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 :

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

Energy and Power Technology:

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:

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:

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


Nanotechnology Nanotechnology is manipulating materials on an atomic or molecular level. Examples: Sensors, Nanobot, molecular manufacturing

Impacts of Nanotechnology:

Impacts of Nanotechnology POSITIVE IMPACTS NEGATIVE IMPACTS IMPLANTED SENSORS IMPLANTED SENSORS Continuously sense and adjust medical treatment Impede privacy
