NATS 101 Contemporary Environmental Problems and Sustainable Society Summer I 2004 University of Arizona Instructor: Dr. Paul Blowers Office Hours: To Be Determined 105E Harshbarger, 6265319 blowers@engr.arizona.edu Lecture: MTWRF 10 am  11:45 am, TA: To Be Determined Office Hours: To Be Determined Course Description: NATS 101 is designed to be an overview of the key concepts in physical and chemical processes, including Newton's laws governing force and motion, the laws of thermodynamics governing energy and entropy, the role of electromagnetism in nature, and the atomic structure of matter. The course will explore these concepts in an interdisciplinary context, drawing from areas such as environmental sciences, atmospheric sciences, engineering/technological sciences, and others. Interrelations between Humans, Engineering, and the Environment In this section, we will have an overview of how physical and chemical processes guide engineering solutions to problems, and how these solutions impact the environment. Examples of topics include air conditioning, solar power, medical technologies, electronics, refrigeration, and other engineering solutions to technological problems. Text: Environmental Science: Working with the Earth, G. Tyler Miller, Ninth Edition or Higher. Supplementary information will be provided for some course materials not available in this text. Course Objectives: Upon completion of this course, students should: 1) be able to understand the implications of Newton's laws regarding force and motion 2) be able to use energy balances to estimate actions using thermodynamics 3) be able to understand the fundamentals of entropy and how they translate to actions 4) be able to understand electromagnetism and its importance in the environment 5) be able to predict behavior of substances based on their atomic structure of matter 6) be able to use the above principles to evaluate engineering solutions to technical problems 7) be able to estimate the environmental consequences of an engineering solution to a technical problem 8) be able to explain to others their opinions regarding engineering solutions to technical problems using the above conscepts 9) perform appropriate mathematical calculations Other metaconcepts the students should be proficient at: 1) be able to comfortably organize and present group material 2) be able to identify and rectify group conflicts 3) be able to identify personal difficulties during learning and to take corrective action 4) be able to knowledgeably think of everyday examples where engineering solutions exist 5) be able to identify the relevance and quality of information used to support arguments, particularly that information regarding engineering and the environment in popular science and general readership magazines Course Policy: Homework quizzes, and group projects (15 % of grade) Homework is due at the beginning of the class on the day it is due. Late homework will not be accepted. Exams (two exams, 20 % each, 40 % of grade total). These inclass exams are comprehensive and are scheduled for 617 and 628. Unless otherwise announced, these exams will be closed book. Laboratory exercises (3 lab write ups, 7 % of grade each, 21% total) Makeup exams: A makeup exam may be arranged if you notify the instructor at least 2 days before the regularly scheduled exam. A makeup exam will be scheduled only if the student has a valid reason for missing the regularly scheduled exam. Verifiable illness with notification from the emergency dean, or family emergencies are valid reasons for missing an exam. Final exam: (24 % of grade). Comprehensive final on Friday 78. A comprehensive final will be given during the scheduled period during finals. Grading Policy: Grades will be posted on a weekly basis online at a website accessible only to students in the class. These grades will be listed according to a random number given to students during the first assignments so only they know their scores. These grades will show the student's score on all assignments and tests and how the student is doing relative to the other students in the course. However, letter grades on exams or assignments will not be determined; a final letter grade will be given at the end of the semester instead. This course will be graded on a straight scale as follows: Total percentage of points earned Final Grade 90  100 % A 80  90 % B 70  80 % C 60  70 % D < 60% E Important Dates to Keep in Mind: Last day to drop a course with a grade of "W" or to change to audit, XXX. Honors Students: Honors students can do honors contract work in this course with an in depth analysis of a technical engineering and environmental issue. This work will culminate in a maximum 10 page report on the topic where multiple competing sides of the issue are detailed. Students will be required to do some basic calculations and estimates to verify or dispute facts on at least one of the issues. Students will then formulate a "best" solution to the issue with appropriate citations to any other work not already introduced. Class Schedule:
All homework is due on the days listed above
unless otherwise designated on a specific problem handout. 1. Briefly restate the problem using a sketch or diagram where appropriate. Label the sketch or diagram with all quantities involved. 2. Indicate the basis you select, and indicate any change of basis within the problem. State assumptions. 3. Include both the numerical value and units for all quantities involved, including intermediate results. 4. Answers should be circled or otherwise marked, and reported to an appropriate number of significant digits. 5. Values obtained from a handbook or other reference should be accompanied by a citation. For example: CCl_{4} boiling pt. 76.5 ^{o}C (CRC, pg C373) 6. Show how you have checked your work if appropriate. 7. Be clear and concise when writing answers to questions. Standards for Style and Presentation of Problem Sets 1. All assignments are to be submitted on 8.5 x 11 inch paper. Multiple pages must be stapled together. Unlined paper may be used if the work is done neatly. Handwriting must be legible. 2. Each page must have the student's name, the course number and the page number in the upper right hand corner. Substandard work will result in a loss of credit. Writing Assignments All writing assignments should be typed, printed on 8.5 x 11 inch paper, and should follow standard grammatical and spelling rules (See Strunk and White). Students will be penalized 5 percent per each typographical or spelling error so be very careful on this issue. Students may resubmit work to earn half of the spelling/grammar points back within one week of them receiving the homework back. Citations should follow any of the standard formats covered in ENGL 101 and 102 courses. Samples of lab writeups will be furnished to guide students in how to write a technical report prior to them having to write their own.
