Directions: Please take out a sheet of paper and answer the following questions. How would I find directions to San Angelo, Texas without using GPS or the internet? Im moving to Tyler, Texas, how can I find a list of the elementary schools near my new home? (without using the internet) What would be the results in your city if sanitation workers went on strike for 1 week? Bell Work Activity 2 Copyright © Texas Education Agency, All rights reserved
A. There are several important terms and definitions students need to know. B. Students will now complete the definitions handout on the History & Development of Technology Innovative Applications of Technology in Engineering - Part 1; Students may work in groups.

The growth of our global population has made the expansion of technology a necessity, to sustain life as we know it. Prior to the Industrial Revolution (1750), most of the global population operated independently in an agrarian (farming) society. Our Dependence on Technology Innovations 4 Copyright © Texas Education Agency, All rights reserved
The Industrial Revolution brought about the movement of large segments of people from the rural areas to the cities in search of employment. This brought about dramatic changes to the structure of society and also drove (and continues to drive) major technological innovations.

We will discuss how modern innovative engineering ideas and techniques have impacted the major technology disciplines. A. Communication Technology: Printing and graphic processes: Gravure printing, Photographic printing and Digital printing Telecommunication processes: Bandwidth improvement with Fiber optic cables, Wireless telecommunications, Satellite telecommunications Audio/Video technologies: Satellite radio, High definition television, Web page design, Video game design Modern innovations in the major technology disciplines 6 Copyright © Texas Education Agency, All rights reserved
Modern innovations in the major technology disciplines (continued) B. Energy and Power Technology: *Renewable Resources: Wind, Hydro (water), Solar, Biofuels (produced from plants), Geothermal (internal earth heat) Non-Renewable Resources: Fossil Fuels (Natural gas, Coal, Petroleum), Nuclear Power (Uranium) Unlimited Resources: (*All renewable resources can be considered unlimited resources ) 7 Copyright © Texas Education Agency, All rights reserved
Modern innovations in the major technology disciplines (continued) C. Biotechnology: Agricultural processes: Genetically modified plants and animals, Biosynthesis (Biologically created chemicals) Medical processes: Electronic implants, Laser surgery, Genetic engineering Waste management: Disposal methods, Biological reprocessing, Waste minimization concepts 8 Copyright © Texas Education Agency, All rights reserved
D. Construction Technology: Construction planning: Residential Construction (apartments, condos, houses), Commercial/Industrial Construction (stores, churches, skyscrapers), Civil Construction (roads, schools, hospitals) Design and management processes: Construction Materials, Safety Factors (fire, earthquakes, hurricanes, etc.) Modern innovations in the major technology disciplines (continued) 9 Copyright © Texas Education Agency, All rights reserved
E. Transportation Technology: Engines, Motors and Transportation Systems: Engine fuel Efficiency and Emissions; Fuel Cells, Hybrid Vehicles, Electric Locomotives; Intermodal Transportation (two or more methods); Efficiency of Container Ships Modern innovations in the major technology disciplines (continued) 10 Copyright © Texas Education Agency, All rights reserved
Modern innovations in the major technology disciplines (continued) F. Manufacturing Technology: *Manufacturing process improvement concepts: Just-in-Time Manufacturing Time and Motion Studies Scientific Management Research and Development processes Computer Aided Design (CAD) 11 Copyright © Texas Education Agency, All rights reserved
How have technological solutions impacted the manufacturing process? A.Positive impact of automation on manufacturing efficiency and cost reduction Having the capacity to produce large volumes of product at lower cost than handcraft workers Programmable robotic processes allow for greater standardization and higher product quality B. Negative impact of automation on human labor Automation allows non-stop production with fewer people; Production not impacted by human limitations (illness, injury, fatigue) Automated processes have made many manual tasks obsolete and does not carry the additional cost of human labor (medical benefits, labor negotiations, training, etc.) C. Increased requirements for a more skilled and educated workforce 12 Copyright © Texas Education Agency, All rights reserved
Risks and Benefits of engineering activities A.Benefit 1: Efficient manufacturing processes (see notes) B. Benefit 2: Safe, efficient transportation and construction systems (see notes) 13 Copyright © Texas Education Agency, All rights reserved
Risks and Benefits of engineering activities (continued) C. Benefit 3: Safe, efficient food production, water distribution and waste management 14 Copyright © Texas Education Agency, All rights reserved
D. Risks: Increased energy consumption and waste creation Energy consumption and pollution since the Industrial Revolution has increased exponentially each decade. The growth of industrialization in third world countries has compounded the problem. We are in danger of consuming and or contaminating major portions of our non-renewable resources. Risks and Benefits of engineering activities (continued) 15 Copyright © Texas Education Agency, All rights reserved
A.Managing environment accidents, pollution and natural resource consumption (mining, petroleum and natural gas production, etc. ) B. *The impact of a mobile population C. Positive management of growth within the key technology disciplines to reduce the impact on our environment The Environmental Impact of the engineering process 16 Copyright © Texas Education Agency, All rights reserved
The Environmental Impact of the engineering process (continued) D. The impact of a mobile population The relocation of the auto industry. (see notes) The impact on the communities left behind. (see notes) E. Positive management of growth within the key technology disciplines to reduce the impact on our environment Long term, environmental planning will be necessary if future generations are to prevent this cycle from re-occurring. 17 Copyright © Texas Education Agency, All rights reserved
