Unit 2:   Industrial Ecology as a System:  
A Conceptual Framework  
                    Answers to Activities
 
 
 
Activity 2.1:   Defining Industrial Ecology
 
This activity is primarily a way of initiating a class discussion; therefore, no specific answers are provided.
 
 
Activity 2.2:  Critiquing Success Stories
 

The research papers for this activity will vary based upon the case study chosen and the research conducted by each student.  Use the following list of criteria as a guide for evaluating their reports:

See Notes on Active Pedagogy for additional suggestions on evaluating students’ work.

 
Activity 2.3:  The Entropy of Your Home
 

Answers to this activity will vary depending upon students’ access to relevant data and the level of detail you ask students to include in their diary of the material and energy flow through their homes.  Students should be able to provide quantitative estimates or measurements of most of the inputs and some of the outputs of their home “system.”  For example, electricity, water, and gas inputs can be estimated from a recent utility bill or by monitoring existing meters.  Students who live in dormitories may have to contact the physical facilities of the university or devise another way of measuring these variables.  Inputs such as food products, packaging, and other purchases can be quantified in terms of weight or volume.  Outputs may be a bit more difficult for students to quantify.  For example, students will not be able to quantify the outflows from electric or gas inputs, but should be able to indicate the use of these materials and their final disposition.  Students can weigh or record the volume of solid wastes and recyclable materials.  Waste water will most likely have to be estimated based upon the amount recorded as inputs.

Students should prepare a clear and concise table that provides a comprehensive list of the types and quantities of all inputs and outputs (even those that are difficult to measure), reused and recycled materials, and waste materials.  Students should also provide a concise two to three page report that summarizes their one-week investigation and considers (1) the environmental implications of their outputs (2) the sustainability of their supply of inputs, and (3) ways to reduce their dependency on unsustainable inputs and wasteful outputs and barriers that may prevent them from doing so.  See Notes on Active Pedagogy for additional suggestions on evaluating students’ written work.
 
 
Activity 2.4:  Putting Local Industry in A Global Context
 

Student reports will vary based upon the industry chosen for analysis.  Use the following general criteria as a guide for evaluating the reports.

You can also include in the evaluation each group’s contribution to the class discussion and the creation of the collective flow chart of the industry.  See Notes on Active Pedagogy for additional suggestions on evaluating students work.
 
 
 
Activity 2.5:  Putting Local Industry in A Global Context
 

Student reports will vary depending upon the product chosen for investigation. Use the following criteria as a guide for evaluating the reports:

See Notes on Active Pedagogy for additional suggestions on evaluating students’ written work.
 
 
Activity 2.6:  It's Not Easy Being Green
 
Students’ essays will vary depending upon the product and the advertisements they choose.  Students should be given the freedom to be creative in their collages, which may consist of magazine and newspaper clippings, product labels or wrappers, photographs, and/or other materials.  Their essays should be written in a style that targets the audience of the environmental group’s newsletter.
