Science and Technology/Engineering
Technology/Engineering, Grade 9 or 10
Additional Ideas for Developing Investigations and Learning Experiences and Suggested Extensions to Learning in Technology/Engineering are in Appendix III.
Please note: For grades 6-high school, there are suggested learning activities after each set of learning standards. The numbers in parentheses after each activity refer to the related technology/engineering learning standard(s).
Broad Concept: The application of technical processes to exchange information includes symbols, measurements, icons, and graphic images.
|6.1 ||Identify and explain the applications of light in communications, e.g., reflection, refraction, additive, and subtractive color theory.|
|6.2 ||Explain how information travels through different media, e.g., electrical wire, optical fiber, air, space.|
|6.3 ||Compare the difference between digital and analog communication devices.|
|6.4 ||Explain the components of a communication system, i.e., source, encoder, transmitter, receiver, decoder, storage, retrieval, and destination.|
|6.5 ||Identify and explain the applications of laser and fiber optic technologies, e.g., telephone systems, cable television, medical technology, and photography.|
Suggested Learning Activities
- Give an example of the following types of communication: human to human (talking), human to machine (telephone), machine to human (facsimile machine), and machine to machine (computer network). (6.4)
- Create specific types of communication: human to human (e.g., talking, telephone), human to machine (e.g., keyboard, cameras), machine to human (e.g., CRT screen, television, printed material), machine to machine (e.g., CNC, internetworking). (6.2, 6.3, 6.4)
- Explain what is meant by the size and focal length of a lens and its application for light theory. (6.5)
- Research a communication technology and the impact lasers or fiber optics have had on that technology. (6.4, 6.5)
