Standard 5 Students will: apply technological knowledge and skills to design, construct, use, and evaluate products and systems to satisfy human and environmental needs. |
Technology Systems
Key Idea: Technological systems are designed to achieve specific results and produce outputs, such as products, structures, services, energy, or other systems.

Commencement |
| • identify familiar
examples of technological systems that are used to satisfy human needs and wants, and
select them on the basis of safety, cost, and function • assemble and operate simple technological systems, including those with interconnecting mechanisms to achieve different kinds of movement • understand that larger systems are made up of smaller component subsystems |
• select appropriate technological systems on the basis of
safety, function, cost, ease of operation, and quality of post-purchase support • assemble, operate, and explain the operation of simple open- and closed-loop electrical, electronic, mechanical, and pneumatic systems • describe how subsystems and system elements (inputs, processes, outputs) interact within systems • describe how system control requires sensing information, processing it, and making changes |
• explain why making tradeoffs among
characteristics, such as safety, function, cost, ease of operation, quality of
post-purchase support, and environmental impact, is necessary when selecting systems for
specific purposes • model, explain, and analyze the performance of a feedback control system • explain how complex technological systems involve the confluence of numerous other systems |
