Bio-related and Agricultural

Technology

Biotechnologytransforms living thingsinto products or new forms of life.

Examples:

Genetic engineering, bionics

Agricultural Technologyproduces plants andanimals for food, fiber, and fuel.

Examples:

Irrigation, food preservation,

weed and insect control

Both deal with living things:

Plants, animals, and people

HEALTH

Improves qualityof life, vitamins,

vaccines,

medications

HEALTH Sideeffects of some

medications

nausea, shortness

of breath, etc.

Impacts of Agricultural

TechnologyPOSITIVE IMPACTS NEGATIVE IMPACTS

FERTILIZERS canmake plants produce

more food per acre

FERTILIZERS havefound their way into

ground water, polluting

good drinking water


12/28

Medical Technology

Medical Technologycreates tools

to treat disease and injury.

Examples:Lasers, prostheses, ultrasound, medications

NEGATIVEIMPACTS

X-RAYS Make it

easier to diagnoseinjuries

X-RAYS Too

many x-rays cancause cancer.


14/28

Environmental Technology

Environmental Technologycreates toolsto minimize the effect of technology on the

development of living things.

Examples: Hybrid vehicles, conservation, waste

management (recycling)


15/28

Impacts of Environmental

Technology


RECYCLING

Improves water andair quality

RECYCLING

Disposal of garbageis more complicated

and time consuming


16/28

Production TechnologyProduction Technologyis the

manufacturingof physical goods on anassembly line and the constructionofstructures on a job site.


17/28

Manufacturing

changes natural orsynthetic materials

into usable

products.Examples: Clothing,

vehicles, food

Construction

Technologybuildsstructures that support

loads and protect us

from the environment.Examples: House, bridge,

roads

Production Technology


18/28

Impacts of Production TechnologyPOSITIVE IMPACTS NEGATIVE IMPACTS

MANUFACTURING MANUFACTURING

CONSTRUCTION CONSTRUCTION

New products help to

make our life easier

and increase leisuretime

Many industries use

materials that can

harm theenvironment

Provides shelter,

improves roads,creates employment

opportunities

Noise and debris,

traffic problems,accidents and

injuries


19/28

The development of materialswith outstanding combinations

of mechanical, chemical, and

electrical properties that makeother advances possible.

Examples: Mosquito repellent

clothing, artificial skin grafts for burnvictims, advanced building materials

such as composite decking

Materials Technology


20/28

Impacts of Materials Technology


NEW MATERIALS

able to reuse recycledmaterials to help the

environment

NEW MATERIALSdont know how the

materials will behave

over long periods of

time.


21/28

Transportation Technology

Transportation TechnologyProvides a way for people, animals,products, and materials to be movedfrom one place to the next.

Examples:

Flight Airplane, rocket, space shuttle

Land Train, subway, automobile, bicycle

Water

Commercial, cruise shipsNon-vehicle Conveyor belts, pipelines

distances faster Accidents


23/28

Energy and Power TechnologyEnergyis the ability or capacity to do work.

Examples:Chemical Energy Gasoline

Mechanical Energy Motion

Thermal Energy Steam

Electrical Energy ElectricityRadiant Energy Light


24/28

Energy and Power TechnologyPoweris 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

airplanesFluid power uses fluids to produce motion

Hydraulic uses a liquid

Pneumatic uses a gas


25/28

Impacts of Energy and Power

Technology

POSITIVE IMPACTS NEGATIVEIMPACTS

Without energy

and power, mosttechnologies would

not exist or work

Overuse of

nonrenewableresources


26/28

Nanotechnology

Nanotechnology is manipulating materials onan atomic or molecular level.

Examples:

Sensors, Nanobot, molecular manufacturing


27/28
