TEACHING MODULE REPORT Vickie S. Durrah NSF RET Fellowship at UIC 2006 1. Abstract During the summer RET Program at UIC, I had opportunity to work under the auspices Dr. Tom Theis, Director of Institute for Environmental Science and Policy to conduct a life cycle assessment (LCA) of volatile organic carbon (VOCs) for a CD or compact disc. This project involved an extensive amount of scientific research via the Internet, scientific libraries, as well as numerous manufacturing industries. I collected a multitude of data and knowledge which I was able to process for use with the several mathematical models to calculate and quantify VOCs as well as human and environmental impact. The module will be taught in two units. The first unit, LCA provides an overview the life cycle assessment, specifically focusing on its use by manufacturers in product development, design, improvement and comparison with the objective of minimizing environmental and human impact. It will also provide a framework for conducting a life cycle assessment as well as examples of the ways in which life- cycle assessments have been applied. The second unit provides an opportunity for students to actually inventory a compact disc through the manufacturing process to quantify VOC emissions with the purpose of assessing and discussing human and environmental impact. During this unit, students will participate in an open forum of discussion with their peers and make informed environmental choices and decisions about the products we consume. This experience will model the research process that I performed throughout my fellowship. It is my contention that most fifth grade students have very little background in terms of environmental concerns. However, this area of environmental science should be introduced early on in their academic careers to invite students to become critical thinkers and analyzers for a more sustainable tomorrow. 2. Objectives Students will accomplish the following objectives: • Use Internet as a research tool. • Organize data into tables using Microsoft Excel. • Generate graphs of the data using Microsoft Excel. • Quantify emissions (VOCs) from manufacturing compact discs. • Identify the key steps in manufacturing a compact disc. • Identify the parts of a life cycle assessment. • Perform a LCA of a compact disc. • Participate in open discussion about alternatives and options in product design, production and development. Students will understand the following concepts as a result of this activity: • How to use a life cycle inventory as a tool in minimizing pollution and waste caused by human activities. • How to infer relationships and draw conclusions from research and scientific data. • How to compare materials and choose alternatives to maximize recycling and reuse of materials and waste. • How to evaluate human and environmental impact of emissions over time. • How to effectively debate and discuss controversial issues in a professional manner. Illinois State Science Standards Addressed: • 11.A.3c Collect and record data accurately using consistent measuring and recording techniques and media. • 11.A.3g Report and display the process and results of a scientific investigation. • 12.E.3c Evaluate the biodegradability of renewable and nonrenewable natural resources. • 13.B.3a Identify and explain ways that scientific knowledge and economics drive technological development. • 13.B.3d Analyze the interaction of resource acquisition, technological development and ecosystem impact (e.g. diamond, coal or gold mining; deforestation). • 13.B.3e Identify advantages and disadvantages of natural resource conservation and management programs. • 13.B.3f Apply classroom-developed criteria to determine the effects of policies on local science and technology issues (e.g. energy consumption, landfills, water quality). • 13.B.3f Using available technology, report, display and defend to an audience conclusions drawn from investigations. RET Experience Correlation: During my research experience this past summer I performed an environmental research project in which I completed a life cycle assessment (LCA) of volatile organic carbon (VOCs) for a CD or compact disc. This project involved an extensive amount of scientific research via the Internet, scientific libraries, as well as numerous manufacturing industries. Much of the information needed to conduct such an assessment was not always readily available. However, I was able to process the data collected with the guidance of Dr. Theis and utilize numerous mathematical models to quantify emissions released during the manufacturing of CD’s and how much our environment and humans are physically affected from these emissions over 25 years. 3. Methodology or Experimental setup This portion of my teaching module will be implemented during consecutive 40-minute class periods for approximately two months. The project will require the use of the computer lab or it could be done in my own classroom using the school’s class sets of laptops with wireless internet access. The students will be utilizing the world wide web as a research tool to collect information about LCAs as well as compact discs. Students will use the data they have collected to produce a portfolio to creatively illustrate and showcase their findings. Students will also utilize Microsoft Excel to organize this data into tables and graphs. It may also be necessary to have students visit a scientific library for the purpose of more in depth data collection, with the teacher as a facilitator. As a result, we will plan to 4. Expected Learning Outcome Students will be assessed on the following criterion. • Completion of a LCA portfolio and report. • Quantification of VOCs and human/environmental impact. • Charts labeling compact disc manufacturing process. • Organization of data into appropriately labeled tables and graphs. • Written analysis and conclusions with respect to their data. • Formal assessment (quiz) on knowledge of LCAs, human/environmental impact. Implementation: The first unit, LCA Research Lab will be implemented in April and the second unit, LCA Analysis will be conducted in May. 5. Budget section 6.
