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).
Energy and Power Technologies-Electrical Systems
Broad Concept: Electrical systems generate, transfer, and distribute electricity.
|5.1 ||Describe the different instruments that can be used to measure voltage, e.g., voltmeter, multimeter.|
|5.2 ||Identify and explain the components of a circuit including a source, conductor, load, and controllers (controllers are switches, relays, diodes, transistors, integrated circuits).|
|5.3 ||Explain the relationship between resistance, voltage, and current (Ohm's Law).|
|5.4 ||Determine the voltages and currents in a series circuit and a parallel circuit.|
|5.5 ||Explain how to measure voltage, resistance, and current in electrical systems.|
|5.6 ||Describe the differences between Alternating Current (AC) and Direct Current (DC).|
Suggested Learning Activities
- Design and create an electrical system containing a source, a switch, and multiple loads. Be able to measure the voltage and current at each load. (5.2)
- Design and create an electrical system with either motors or lights. All of the motors in the system will operate at different speeds, or the lamps will operate at different intensities. (5.2, 5.3)
- Create schematics for series, parallel, and combination (series-parallel) circuits, and construct them from the schematics. (5.4)
