1. What is Technology? The process by which humans modify nature to meet their needs and wants.

2. How does Technology differ from Science? Technology Technology  Study of our human-made world  Deals with “what can be” Science  Study of our natural world  Deals with “what is”

3. How does Technology differ from Science? Technology Technology  Made up of subtopics, such as  Transportation  Communicatio n  Production  Energy  Construction Science Science  Made up of subtopics, such as  Biology  Chemistry  Physics  Earth Science  Space Science

4. Technology develops products to satisfy our needs and wants. What are our needs? What are our wants? PHYSICAL NEEDS: BIOLOGICAL NEEDS: PSYCHOLOGICAL NEEDS: SHELTERCLOTHINGFOODWATERFAMILYFRIENDS

5. How does technology meet our needs? There are sub- categories of Technology. Information and Communication Bio-Related and Agricultural Manufacturing Construction Transportation Technology Production Energy and Power Medical Environmental

6. Communication Technology A process of giving or exchanging information. It has: A process of giving or exchanging information. It has:  Streamlined publishing techniques and allows us to produce more accurate drawings.  Expanded entertainment choices.  Enabled us to contact people thousands of miles away.

7. Communication Technology Examples Cell Phones Cell Phones Computer Aided Drafting Computer Aided Drafting Video Cassette Recordings Video Cassette Recordings Internet Internet Radio Radio Television Television Graphic Arts Graphic Arts

8. Impacts of Communication Technology POSITIVE IMPACTS NEGATIVE IMPACTS CAD – using a computer to generate drawings INTERNET – a means of communicating quickly and inexpensively over long distances PAPER USAGE – people tend to create and print more documents INTERNET – people tend to misuse the internet for personal gain

9. Bio-related and Agricultural Technology Biotechnology applies the principles of biology to create commercial products or processes. Biotechnology applies the principles of biology to create commercial products or processes. Agricultural technology makes it possible for food to be available year-round and to conserve resources. Agricultural technology makes it possible for food to be available year-round and to conserve resources. Deals with living things Deals with living things  Plants  Animals  People

10. Bio-Related and Agricultural Technology examples Medical Medical  Vaccine  Pharmaceuticals  Artificial limbs  Ergonomics – the study of designing equipment to fit the human body, its movement & thinking patterns Artificial Ecosystems Artificial Ecosystems  Sanitation  Artificial intelligence  Robotics Agriculture  Food, Fiber, and Fuel  Plant growth  Genetic engineering  Hydroponics – growing plants in a soil-less environment Environmental  Conservation  Synthetic energy  Waste management

11. Impacts of Bio-Related and Agricultural Technology POSITIVE IMPACTS NEGATIVE IMPACTS HEALTH – improves quality of life. HEALTH – Drugs may cause birth defects. ENVIRONMENTAL – can produce more food per acre than before. ENVIRONMENTAL – Chemicals have found their way into ground water, polluting good drinking water.

12. Production Technology Manufacturing Manufacturing  Changes materials into usable products  Natural (found in nature) or  Synthetic (human-made)  Most takes place in factories  Results in items that are either consumer products (used up) or industrial products (used to make other products)

13. Manufacturing examples Clothing Clothing TV TV Automobiles Automobiles Chemical products Chemical products Lumber Lumber Steel Steel Food Food

14. Production Technology Construction Construction  Building a structure – made by joining parts to meet a certain need.  Involves building a foundation, erecting the super structure, and finishing work.  Supporting the load – external force on an object.  Controlling the quality of construction using control systems.

15. Examples of Construction Technology Human-made structure:  Houses  High-rise buildings  Bridges  Roads  Dams  Schools

16. Impacts of Production Technology POSITIVE IMPACTS NEGATIVE IMPACTS MANUFACTURING – new products help to make our life easier and increase leisure time. MANUFACTURING – many industries use materials that can harm the environment. CONSTRUCTION – provides shelter, improves roads, creates employment opportunities. CONSTRUCTION – noise and debris, traffic problems, accidents & injuries

17. Transportation Technology The process by which people, animals, products, and materials are moved from one place to the next. The process by which people, animals, products, and materials are moved from one place to the next.  Flight  Land Transportation  Water Transportation  Goods Transportation

18. Examples of Transportation Technology Air Air  Airplane  Rocket  Space Shuttle  Helicopter Water Water  Commercial ships  Cruise Ships  Utility vessels Land  Train  Subway  Automobile  Bicycle Goods  Conveyor Belts  Robots  Trucks

19. Impacts of Transportation Technology POSITIVE IMPACTS NEGATIVE IMPACTS Commuting is easier; Traveling long distances faster PollutionAccidents Use of energy

20. Energy and Power Technology Energy is the ability to do work. Energy is the ability to do work. Power is the rate at which energy is transformed from one form to another or as the rate at which work can be done. Power is the rate at which energy is transformed from one form to another or as the rate at which work can be done. Technological products and systems need energy to function. Technological products and systems need energy to function. The availability of energy often determines the development of technology. The availability of energy often determines the development of technology.

21. Examples of Energy and Power Technology Chemical Energy Chemical Energy  Gasoline Mechanical Energy Mechanical Energy  Motion Thermal Energy Thermal Energy  Steam Power Measurement Examples: Horsepower Horsepower Kilowatt Kilowatt Electrical Energy  Electricity Radiant Energy  Light Power System Examples: Turbines Portable generators

22. Impacts of Energy and Power Technology POSITIVE IMPACTS NEGATIVE IMPACTS Without energy and power, most technologies would not exist or work. The overuse of natural resources is a concern of many people.
