Peer grading Certification: I certify I have fairly and carefully evaluated this work to the best of my ability. I have cross checked this grading with a peer. In addition, I have discussed the grading of the packet with the author. Finally, I understand if my grade is 10% off of Mr S or Mr N’s final score, the difference will be deducted from all students involved.

Waste Systems Analysis Guidelines for Figures 1-3
Mission:  To compare and contrast our three different waste handling systems.
Resources:      a. Your Where does my Waste Go graded assignment.     b. www.goscienceseven.com

1. Use Figures Format. Written answers can be attached, if properly headed
2. Draw the inputs, outputs, flows and boundaries for these three waste systems.
   1. Mixed Solid Waste (including Roosevelt Landfill, Roosevelt WA)
   2. Recyclables (include Cascade Recycling Center, Woodinville, WA & BEYOND)
   3. Yard waste (Cedar Grove Composting, Smith Island, WA & BEYOND)
3. Use your Where does My Waste Go? assignment to help track/show each step the matter and energy in the waste system makes in the system.
4. Each Figure should completely answer Level One Steps 1&2 and Level Two Steps 3 &6. Use complete sentences/ink for written answers.
5. Use this Key for flow arrows

   Matter Inputs = Green	Matter Outputs = Blue	Matter Cycling = Purple
   Energy Inputs Red	Energy Outputs Orange
   Boundary = Yellow

                   

Level One: System Analysis steps:

1. Is this a system? If yes, tell what kind of system (Open or Closed) and explain why using Matter and Energy descriptions.
2. Draw the system showing the:

a. Boundaries           b. Inputs                c. Outputs             d. Flows

Level Two: Interacting Systems Analysis steps

3.  Does the output of this system become an input of another system?  If so, describe the other system.
4. Tell if the input of matter or energy into this system the Same, Less or More then the output?
5. Are there any subsystems contained within this system?  If so tell what these are.
6. Is this system a subsystem of another, even larger system?  If so, describe the larger system.
