Core Technologies

Instruction on the Core Technologies will provide you with an understanding of:

a. common components,

b. basic systems design,

c. simple controls,

d. system performance evaluation,

e. science concepts applied,

f. mathematics applications to measure, analyze, describe and predict, and

g. safety practices for interacting with technology systems.

PresenterPresentation NotesKeep in mind that each core technology is a system. Visible movement is not a requirement to be a system. Only input, processes, output and sometimes feedback are required in a system.

Core Technologies Produce Technology Systems

PresenterPresentation NotesTechnology is a human activity. Technology is seen in every aspect of human ingenuity. The list of technological activities is listed here in four major areas of society.

CO

RE

TEC

HN

OLO

GY

DescriptionThe technology of putting mechanical parts together to produce, control and transmit motion.

ApplicationsGear systems in a car transmission, brakes on a bicycle, agitator on a washing machine, latch set on a door

Mechanical Technology

Bicycle

PresenterPresentation NotesMost of the energy developed by humans is to do physical work. It's the transfer power to do the work that is most associated with mechanical technology. Mechanical technology is also the easiest to see the work happening with the human eye.

CO

RE

TEC

HN

OLO

GY

Description

The technology of producing, storing, controlling, transmitting and getting work from electrical energy.

Applications

Power plant generator, flashlight battery, light switch, electric motor in a can opener, door bell, electric heater, hair dryer

Electrical Technology

Power Plant

PresenterPresentation NotesElectrical technology is where electricity is required to do work. Electricity is generated and sent to homes, schools, and hospitals usually be used to operate machinery or lighting. Most homes use 110 to 240 volts of electricity.

CO

RE

TEC

HN

OLO

GY

Description

The technology of using small amounts of electricity for controlling; detecting; and information collecting, storing, retrieving, processing and communicating.

ApplicationsThermostat for controlling temperature, a metal detector, video tape recorder, computer, pocket calculator, telephone, radio and television

Electronic Technology

Radio/CD Player

PresenterPresentation NotesUnlike electricity, which generates and uses higher voltages, electronic technology uses very low voltage. Many electronic devices use batteries to provide its power. When asked what is the difference between electricity and electronics, one could say about 100 volts.

CO

RE

TEC

HN

OLO

GY Description

The technology of putting parts and materials together to create supports, containers, shelters, connectors and functional shapes.

Applications

Legs of a chair, city water tower, swimming pool, buildings, storm sewer, airplane wing, satellite antenna dish

Structural Technology

Microwave Tower

PresenterPresentation NotesStructural technology does not typically show any motion or movement. Structural technology must accommodate the movement or stresses it is placed on an apparatus or architecture created by humans. The movement maybe created by winds acting on a high-rise building or a train crossing a bridge. Each of these movements create tension on the object that the the material and the design must support.

CO

RE

TEC

HN

OLO

GY Description

The technology of using fluid, either gaseous (pneumatics) or liquid (hydraulic) to apply force or

to transport.

Applications

Air brakes on a truck, tires on a car, airfoils on an airplane, warm air heating ducts and fan in a building, hydraulic jack, plumbing in a school, gasoline pump

Fluid Technology

Gas Pump

PresenterPresentation NotesFluid technology or hydraulics requires a liquid under pressure to do work. Pushing fluids through a tube at one end will move the fluids through the tubes to do work at the other end of the tube. Fluids can be used to lift or move heavy objects because fluids do not compress. Pneumatic systems work the same way but air does compress so it needs a different application to be efficient.

CO

RE

TEC

HN

OLO

GY Description

The technology of producing light; controlling light, using light for information collection, processing, storage, retrieval and communication, and using light to do work.

ApplicationsLight bulb, LED (Light Emitting Diode), lenses to magnify and reduce, laser speed detector, laser compact disk, fiber optic telephone communication, laser cutting tools, laser surgery instruments

Optical Technology

telescope

PresenterPresentation NotesOptical technology uses light to do the work. The scanner reading a barcode at a supermarket or an x-ray or an alarm used during bowling to tell the scoring machine if you've crossed the line are all optical technology applications.

CO

RE

TEC

HN

OLO

GY Description

The technology of producing, storing, controlling, transmitting, and getting work from heat energy.

ApplicationsFurnace, hot water heater, toaster, insulation, heat exchanger (radiator, condenser), refrigerator, jet engine

Thermal Technology

Jet Plane

PresenterPresentation NotesThe use of the term thermal relates to heat. A solar blanket on a swimming pool transfers energy from the sun to impact the water temperature. An oven used to cook a meal or a furnace to heat a home are thermal technology. Greenhouses are examples that get overlooked when thinking of thermal technology.

CO

RE

TEC

HN

OLO

GY Description

The technology of using, adapting and altering organisms and biological processes for a desired outcome.

Applications

Stain eating enzymes in detergent, bacteria leaching of metals from ore, altering plant genes to produce better crops

Biotechnology

Chemical Solutions

PresenterPresentation NotesBio means living. So biotechnology uses living things to solve human problems or extend human potential. This is the fastest-growing technology area in the past 20 years.

CO

RE

TEC

HN

OLO

GY

DescriptionThe technology of producing, altering, and combining materials.

ApplicationsProducing paper from wood, producing aluminum from ore, drilling holes in wood, annealing to soften metal, casting ceramic, welding metal, laminating wood

Size of Technology Systems

PresenterPresentation NotesTechnology systems come in many shapes and sizes and again are very simple in design to extremely complex. Science and mathematical theories can be used to determine a system's performance before it is actually developed.

SummaryThe Core Technologies are considered to be the "basic building blocks" from which all technology systems are created.

There are nine Core Technologies: (a) mechanical technology, (b) electrical technology, (c) electronic technology, (d) structural technology, (e) fluid technology, (f) optical technology, (g) thermal technology, (h) biotechnology, and (i) materials technology.

Technology systems can be small or large, simple or complex.

The Core Technologies are the bridge between science concepts and real-world technology. They provide numerous opportunities to describe, analyze, and predict physical phenomena using mathematics.

PresenterPresentation NotesIn summary there are nine core technologies covered extensively in the curriculum in Maryland. Core technologies are the systems that do all the work. From moving fluids through one's body during surgery, to dissolving cataracts, from lifting heavy objects, to detecting voltage drops in a system. The nine core technologies are the drones of the technological colony.
