Introduction to Technology

Definition of Science • -knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method. – Webster’s New Collegiate Dictionary

Definition of Technology • -Using knowledge to develop products and systems that satisfy needs, solve problems, and increase our capabilities.

The four major areas of technology Transportation: The process by which people, animals, products, and materials are moved from one place to another. Production: The act or process of producing. Communication: A process of giving or exchanging information Biotechnology: The use of living organisms to make commercial products.

Activities of Technology (5) 1. Manufacturing- processes used in factories and shops to create productsinvolve the processes of forming, separating, combining, and conditioning materials. 2. Communication-process used to exchange information

Activities of Technology (5) 3. Transportation- processes used to move people or goods. ie outside the factorytrucks, railroads, ships. Within factoriescranes and conveyors. 4. Construction - processes used to build the structures in which manufacturing takes place

Activities of Technology (5) 5. Biotechnology- processes used to make or change products using living organisms. • The result of combining biology with technology – technologies that control industrial robots in factories have been adapted to human needs. For example myoelectric limbs use small motors and electronic circuits to control humanlike movement of the artificial limb.

System • Input – something that is put into a system • Process – the part of a system during which something is done or the “action” • Output – results of the system • Feedback – information about the output • Monitor – displays what is currently happening in the process

Systems An orderly way of achieving a goal Keep house at 67 degrees Adjust Input process Output Process 7 resources Monitor Identify each part as it applies to a Home Heating System

Subsystems Complex systems are made up of smaller systems called subsystems. • I. e. - Stereo system Subsystem – – CD Player Tape player Radio Speakers

Impacts “The power of an event or idea” What are some examples of both positive and negative impacts of a specific technology (Do the positive impacts outweigh the negative? If not do we continue this technology? ) • Automobile • Computers +, +, - • Genetic Engineering +, -

What’s in the Future • • • Space travel/ colonization of other planets? Time Travel Health School Jobs Food

Technology through time • All people have needs and wants- food, water, shelter, communication, protection, recreation, transportation, and health care.

Prehistoric / Stone Age • - used simple technology for basic needs • -made stone axes for various needs – hunting animals for food – protection – construction of shelter

Agricultural Age • After settling in villages, peoples activities centered around farming and raising livestock. • Agriculture changed how people lived and worked. • New technologies developed to satisfy new wants and needs • Hoe, plow and sickle were developed

Time Passes • People learn more about their world and undertake more complex tasks. • Development of the loom to weave fabric. • Trade develops so the need for transportation increases. • Systems are developed and improved upon. • Bridges and better roads make it easier to move between villages.

Industrial Age • In 1700’s new technology exploded on to the scene • Steam engine enabled factories to produce new products • Transportation systems improved to move goods and people faster

Information Age • Began in the 1950’s brought on by the need to gather, organize, store, and share information. • The Information Age was built upon the development of the transistor and the computer

Information Age • The technologies of the Information Age touch all aspects of life. – Fuel the research that has advanced medicine – doctors can diagnose and treat illnesses that previously couldn’t be cured – Need for recreation- video games, portable stereos, CD players, video recorders, in line skates
