I will notify you in class about any changes or corrections. THE COURSE: Geology is a very broad science encompassing earth (and planetary) processes. This introductory course will open a whole new universe to you in which you will learn about the amazing geological features on the earth and the rich geologic history of this planet. We will touch on subjects such as rocks and minerals, mountain building, volcanoes, ocean basin formation, rivers, and Washington regional geology. OBJECTIVES These are the specific outcomes for Geology 101. PLO represents Program Learning Outcomes for the Science disciplines, which may be found in the TCC catalog at this location: http://www.tacomacc.edu/catalog/11-12catalog/. Each outcome may or may not relate to one or more of the Science PLOs. 1. Describe the characteristics and origin of the major classes of rocks and minerals. Classify rock and mineral samples. Identify rock samples in the field. PLO: 3, 4 2. Describe the diversity of volcanic activity on earth. Explain the variation in volcanic mountain shapes and eruptive styles. Describe volcanic hazards and assess the regional risks due to volcanic activity. PLO: 3 3. Describe seismic energy and its relationship to faults. Describe the geologic consequences of earthquakes and explain our ability to forecast and otherwise cope with these occurrences. PLO: 3 4. Use experimental models to better understand earthquake mechanics. PLO: 3 5. Describe the structure of the earth and explain how seismic evidence supports these ideas. PLO: 3 6. Explain how the interior structure of the earth relates to the process of plate tectonics. PLO: 3 7. Describe the three main types of plate boundaries and the main geologic activity occurring at each. PLO: 3 8. Explain how stresses in the earth deform crustal rocks. Use experimental models to visualize strain. PLO: 2, 3 9. Explain seismic hazards in the Pacific Northwest and consider how this risk can be mitigated. PLO: 3 10. Describe relative and absolute methods for measuring geologic time and demonstrate proficiency in using the geologic timescale. PLO: 3 1 11. Describe the fundamental concepts governing stream systems such as capacity, competence, and channel structures. Explain how fluvial systems alter the landscapes of the earth. Critique land use practices as they relate to flood plains. PLO: 3 12. Describe hydrogeologic concepts such as, infiltration, aquifers, aquicludes, and the potentiometric surface. Explain the importance of groundwater as a resource. Recognize typical misuses of groundwater systems. PLO: 3 13. Describe the concepts controlling glacial growth and flow. Explain the origin of glacial landscapes and the features in them. Use observations collected in the field to understand the glacial origins of our local landscapes. PLO: 3 GRADING: Grading will be based on the criteria below. The course grade will be determined by adding the percentages from each of the categories below. A simple, straight percentage scale will then be used to assign course grade: 100%-92.5% is an A, 92.5%-90.0% is an A-, 90.0%-87.5% is a B+, 87.5%-82.5% is a B, 82.5%-80.0% is a B-, 80.0%-77.5% is a C+, 77.5%-72.5% is a C, 72.5%-70.0% is a C-, 70.0-%-67.5% is a D+, 67.5%-60.0% is a D, less than 60% is an E). Rock Quiz Rock identification key Geotour presentation/ Public Safety brochure In-class exercises Exam I Exam II Exam III (comprehensive) Labs and Fieldtrips Symposium Bias exercise 5% 3% 6% 4% 15% 15% 18% 24% 9% 1% Rock Quiz This quiz is based on hand specimen identification and will be given during lab time. The specimens are rocks types that will be covered during the first three labs. Students are responsible for both identifying each rock or mineral by name and discussing the origin of the specimen. See the course materials booklet for a list of rocks and minerals that students are responsible for. In-class exercises These are short exercises that we will do in lecture from time to time, schedule to be determined, which are also due in lecture the day we complete them. The topics vary but the goal is for students to work with concepts that we cover in lecture in order to better understand the material. We will complete about 15 different in-class exercises. No credit is granted for each unless the student is present in class and turns in the exercise at that class meeting. Geotour presentation This is a presentation to the class based on a Google Earth tour of a landscape feature of your choice, plus additional photos and figures as needed in a PowerPoint. The assignment may be done independently or with a partner. Both partners will receive the same grade unless major complications arise, in which case I will assign grades on a case by case basis. At the beginning of the quarter I will schedule the presentations. You must schedule the presentation before 10/5. See the Geotours assignment description in the Course Materials book for more details about what I expect. The presentation grade will be based on: description of the site (20 points), geologic origin of the site (40 points), use of Google Earth and/or other visual aids (20 points), presentation delivery (20 points). ALTERNATIVELY, YOU CAN COMPLETE THE ASSIGNMENT BELOW Public safety brochure For this assignment you will design and print a public safety brochure about one of the following topics (or a topic of you own selection but please talk to me first): volcanic hazards in Pierce County, tsunami hazards in Puget Sound and the Washington coast, earthquake risk in western Washington, groundwater contamination issues, flooding risks in Pierce County, soil contamination in Ruston and Tacoma. The assignment may be done independently or with a partner. Both partners will receive the same grade unless major complications arise, in which case I will assign grades on a case by case basis. 2 See sample brochures in class for ideas for layouts. The brochure must include the appropriate technical detail about the geology as well as advice on how to avoid the hazard or prepare for it, or preserve the resource. I want to see a thorough understanding of the geology on the part of the student. You can use the approximate ratio of 2/3 geology to 1/3 safety information, as a guide. Do use figures where appropriate. Grading will be based on: the accuracy and depth of the technical content (50 points), the organization and relevance of the advice (25 points), and the general layout and accessibility of the brochure (25 points). Brochure due 11/23. Exams The exams will cover both lecture and reading material. Materials in the labs may appear on the exams but only if it is information that is redundant with the lectures and reading. No makeup exams will be given unless you discuss it with me beforehand. They will be multiple choice exams and will include a variety of question formats such as diagrams, matching, true/false, and the standard multiple choice questions. Labs/Fieldtrips The lab grade will be based on completed lab work. Lab exercises are completed during lab time and turned in at the end of the lab period. Graded exercises will be returned within one week. The exercises are designed to reinforce the content and concepts covered in the lectures and reading. Symposium The symposium, taking place during lab on 11/10 and 11/12, will consist of student groups of about four giving a presentation to the rest of the lab section on the topic of new techniques in oil and natural gas extraction. Each lab section will be divided into about five groups and each group will be assigned to address one aspect of natural gas. The group will be responsible for researching the topic and then during the presentation part, summarizing the topic for the other student groups in the lab section. The presentation needs to include: 1) a PowerPoint slide show to help illustrate the discussion; 2) a well organized oral discussion of the topic presentation Grading will be based on the quality of the presentation and PowerPoint as determined by the instructor. I will solicit feedback from each audience group about the quality of each presentation and from each research group member about the degree of participation of the other group members. Each student will also be required to answer questions about each topic they listen to. I will assign specific aspects of the topic to individual research groups to address. More details are in the Course Materials book. Bias exercise This is a library research exercise that you will do individually in association with the symposium described above. See the Symposium library guide for instructions. CLASS POLICIES: Assignments Late work will have 25% of the score deducted per class day until there is nothing left. No late work will be accepted if I have already graded and returned the assignment to the rest of the class. Please understand that I must act on behalf of the students in the class who complete their assignments on time. Attendance There is a high correlation between lecture attendance and course performance. If you do not regularly attend lecture it is very unlikely that you will do well in the course. The opportunity for personal interaction with the instructor is invaluable. In addition, at the end of the quarter if your course grade is borderline (<0.5% close to the next category), a strong attendance record will encourage me to give you the higher grade. Other reasons for strong attendance include: announcements made in lecture will not necessarily be repeated elsewhere, as this is not a web-enhanced class; in-class exercises may only be completed in lecture; Geotours will have test questions associated with them, so if you don’t hear the Geotour you’ll have a hard time answering the questions from them on the exams. Lab attendance is mandatory. In order for you to receive credit for a lab you must attend. There are no make-up labs. Because the labs are an integral part of the class, more than three unexcused, missed labs will result in a failing grade for the entire course. Further, punctuality is required. I want you to come to the lab but you have to be on time. The doors to the lab room will be locked about 3-5 minutes after the lab meeting begins. If you come after this time, I will let you in but I will deduct 50% of your lab points from that day’s assignment. 3 Field trips Some of the labs will involve local field trips. Dress appropriately and wear sturdy shoes. Also bring note-taking materials. See the Course Materials booklet for more information about the fieldtrips. Withdrawals and Incompletes November 13h is the last day to withdraw from the course with a grade of “W.” Under appropriate circumstances students may obtain an incomplete for the course. This option requires that the student fulfill the remaining requirements within a designated amount of time. Cheating Cheating on an assignment or exam will result in zero credit for that item and appropriate action as outlined in the TCC catalog. Plagiarism is likewise unacceptable. See the TCC Students Bill of Rights and Responsibilities for more information about cheating and plagiarism. Late material/missed quizzes or exams To reiterate policies stated above, late materials are subject to 25% reduction in points per day it is late, and there are no make-up quizzes or exams unless you contact me (phone, in person, or by email) before the original scheduled time of the quiz or exam. If you contact me after the quiz or exam has already taken place you are ineligible for a make-up. The only exception to this is a medical or family emergency that prevented you from attending class. In this case I may grant an exception but I will require written documentation of the emergency. Students with Special Needs All students are responsible for all requirements of the class, but the way they meet these requirements may vary. If you need specific auxiliary aids or services due to a disability, please contact the Access Services office in Building 7 (253-566-5328). They will require you to present formal, written documentation of your disability from an appropriate professional. When this step has been completed, arrangements will be made for you to receive reasonable auxiliary aids or services. The disability accommodation documentation prepared by Access Services must be given to me before the accommodation is needed so that appropriate arrangements can be made. Accommodations for disabilities Accommodations for physical disabilities will be made insofar as they are possible. The lecture and laboratory work will take place in a classroom setting and should present no difficulties. Fieldtrips are mostly roadside and requires minimal walking. However, if you have a physical disability, please speak with the instructor before the course begins. Classroom disputes If you have questions or concerns about this class or me, please come to talk with me about your concerns. If we are unable to resolve the issue the next step is to talk to the Science and Engineering Department Chair, Katie Gulliford. CLASSROOM BEHAVIOR General I expect basic courtesy: no conversations with neighbors during lectures, no leaving in the middle of lecture, and punctual arrival to class, labs, and fieldtrips. Electronic devices Cell phones will turned off or silenced in class and in the field while class is in session (unless arranged with me beforehand). No texting. Computers may be used for note taking or topic research during class. If a student uses a computer for other functions I will ban them from using it in class for the duration of the course. If a student persists in rude behavior, counter to what I outlined in the two sections above, I will take appropriate measures, contacting administrative officials if necessary. CALENDAR: The reading should be completed before we cover the topics. This way you are exposed to the information and ideas twice and have the opportunity to iron out any difficulties. Although I expect the lectures to follow the calendar fairly closely there will undoubtedly be times when we stray. It is up to you to make sure that you are keeping up on the appropriate reading assignments. The labs will meet almost every week. Consult the calendar for lecture and lab topics. 4 Week Topic Marshak 1 9/21-9/25 introduction to earth structure and plate tectonics minerals igneous rocks LAB 1: Minerals pp. 1-33 pp. 70-87 pp. 88-117 2 9/28-10/2 igneous rocks (cont.) volcanoes LAB 2: Igneous Rocks pp. 88-117 pp. 118-147 3 10/5-10/9 weathering and soils sedimentary rocks metamorphic rocks LAB 3: Weathering, Sedimentary and Metamorphic Rocks CHOOSE GEOTOUR TOPIC BY 10/5 pp. 148-161 pp. 122-187 pp. 188-215 4 10/12-10/16 review for Exam 1 lecture topic TBA LAB: Movie, in lab room 10/12: Exam 1 in Class 5 10/19-10/23 earthquakes EDUCATIONAL PLANNING DAY TUES 10/20-NO DAY CLASSES NO LAB MEETINGS THIS WEEK pp. 216-251 6 10/26-10/30 the earth’s interior plate tectonics 10/27 and 10/29: Rock Quiz in Lab pp. 252-263 pp. 34-69 7 11/2-11/6 plate tectonics (cont.) folding, faulting, and mountain building LAB 4: Earthquakes pp. 34-69 pp. 264-291 8 11/9-11/13 folding, faulting, and mountain building (cont.) review for Exam 2 11/12: Exam II in Class HOLIDAY WED 10/11-NO LECTURE LAB: Symposium, 11/10 and 11/12 pp. 264-291 9 11/16-11/20 Pacific Northwest earthquake hazards fluvial systems LAB 5: Puget Sound glaciations No assigned reading pp. 416-443 10 11/23-11/24 Groundwater Public Safety brochures due 11/23 NO LAB MEETINGS pp. 473—487 11 11/30-12/4 glaciology and ice ages pp. 514-534, 534-567 (second set of pages optional) Fieldtrip #1- Steilacoom gravel quarry, during lab Review and Exam III, Monday, 12/7, 8:30a-10:30a, in 10-1 5
