Considering Systems and Controls
Our world is filled with systems.
Complex systems have control mechanisms. Without controls the systems are likely to breakdown or malfunction.
1. For each system shown in bold write its major function.
You may not know much about the system. You may need to learn more about a system to find the examples of controls.
Vehicle (identify 2 controls)
Cafeteria (identify 2 controls)
Vertebrate's Digestive system (identify 2 controls)
A communication device (identify 2 controls)
Extend your thinking:
Find a similarity in the functioning of controls for two of the systems.
Sometimes two systems interact and specialized controls are developed.
Could one of these systems be improved with a change in a control? Explain.
In something that consists of many parts, the parts usually influence one another.
Watch The Disappearing Delta: Losing Ground. Identify the system. Give an example of how one part of the system influences another part of the system.
How has man impacted this system?
What should happen now?
A picture is worth...
People seek to understand systems by mapping them. Give an example.

Save a tree use a digital answer format - Highlight the text. Copy it. Paste it in a word processing document. Save the document in your folder. Answer on the wp document in a contrasting color (not yellow) or font. Or perhaps you have the resources to record verbal answers. If you do, be sure to first read / record the question. Then record the answer immediately after it.
Proof your responses. It is funny how speling errors and typeos sneak in to the bets worck.
