Enduring Understandings

 * Many forms of technology rely on a complex web of inputs, processes, outputs, and feedback.
 * Complex information can be simplified into streams of binary digits.

Prior Learning (from S8 Anchors)
S8.A.3.1 Explain the parts of a simple system, their roles, and their relationships to the system as a whole. S8.C.2.1 Describe energy sources, transfer of energy, or conversion of energy.
 * S8.A.3.1.1 Describe a system (e.g., watershed, circulatory system, heating system, agricultural system) as a group of related parts with specific roles that work together to achieve an observed result.
 * S8.A.3.1.2 Explain the concept of order in a system [e.g., (first to last: manufacturing steps, trophic levels); (simple to complex: cell, tissue, organ, organ system)].
 * S8.A.3.1.3 Distinguish between system inputs, system processes, system outputs, and feedback (e.g., physical, ecological, biological, informational).
 * S8.A.3.1.4 Distinguish between open loop (e.g., energy flow, food web) and closed loop (e.g., materials in the nitrogen and carbon cycles, closed-switch) systems.
 * S8.A.3.1.5 Explain how components of natural and human-made systems play different roles in a working system.
 * S8.C.2.1.1 Distinguish among forms of energy (e.g., electrical, mechanical, chemical, light, sound, nuclear) and sources of energy (i.e., renewable and nonrenewable energy)
 * S8.C.2.1.2 Explain how energy is transferred from one place to another through convection, conduction, or radiation.
 * S8.C.2.1.3 Describe how one form of energy (e.g., electrical, mechanical, chemical, light, sound, nuclear) can be converted into a different form of energy.
