14. 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

15. Bio-related and Agricultural Technology
Biotechnology is the application of the principles of biology to create commercial products or processes.
Agricultural Technology is the application of processes that make it possible for food to be available year-round and to conserve resources.
Both deal with living things
Plants
Animals
People

16. Examples of Bio-Related and Agricultural Technology

20. Impacts of Medical Technology
POSITIVE IMPACTS
NEGATIVE IMPACTS
HEALTH – improves quality of life
HEALTH – use of technology may hinder life span
DISEASE – research on controlling diseases and their spread is shortened
DISEASE – not all cultures embrace use of vaccines and thus disease spreads

21. Environmental Technology
Environmental Technology is study of the processes to control waste, soil erosion, reducing sediment in waterways, conserving water, and improving water quality, artificial ecosystems, and the effects of technology on the development of flora and fauna.

22. Examples of Environmental Technology
Conservation

EARTH – use of technology may hinder life span of the planet
DISEASE – reduces chance of disease from bad air and chemicals
DISEASE – economical forces the need to make choices that are not easily made

24. Production Technology
Production Technology is the manufacturing of physical goods on an assembly line and the construction of structures on a job site.

25. Manufacturing
Manufacturing is the process of changing materials into usable products
Natural (found in nature) or
Synthetic (human-made)
Most takes place in factories on assembly lines
Results in items that are either consumer products (used up) or industrial products (used to make other products)

26. Examples of Manufacturing Technology
Clothing
Entertainment devices
Automobiles
Chemical products
Lumber
Steel
Food

27. Construction Technology
Construction Technology is the study of the processes to
Build a structure – made by joining parts to meet a certain need.
Involves building a foundation, erecting the super structure, and finishing work.
Support the load – external force on an object.
Control the quality of construction using control systems.

28. Examples of Construction Technology
