GEOLOGY 3505 - Earth Systems History III
North Terrace Campus - Semester 2 - 2020
General Course Information
Course Code GEOLOGY 3505 Course Earth Systems History III Coordinating Unit School of Physical Sciences Term Semester 2 Level Undergraduate Location/s North Terrace Campus Units 3 Contact Up to 6 hours per week Available for Study Abroad and Exchange Y Prerequisites GEOLOGY 2500 Incompatible GEOLOGY 3014 Course Description This course studies the fundamental geological and biological processes comprising the Earth System. It focuses on the interactions between the biosphere and the geosphere as the Earth System evolved, and on how those processes can be deciphered through the analysis and interpretation of sedimentary archives. The course will highlight the approaches used to interpret those archives, particularly the geochemical and physical techniques used to quantitatively constrain past climate and biogeochemical cycles, and those used to determine the age and rate of sedimentary deposits. The application of these techniques will be illustrated alongside a narrative of some of the key transitions in Earth's history, including the origins of the atmosphere, ocean and life, carbon cycle fluctuations through time, the expansion and demise of global ice ages and the role of humans in the modern Earth system. With a strong focus upon critical analysis and debate, the course will provide a scientific grounding relevant to a variety of contemporary issues, including resources, climate change and sustainability.

Specific Course RequirementsThis course has a one-day field trip held in class time.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment Task Task Type Percentage of total assessment for grading purposes Hurdle

Assessment Related RequirementsAttendance at workshops is compulsory. Students are able to apply for an allowed absence from a class by submitting the application form with appropriate documentation to the Course Co-ordinator. Application forms can be downloaded from http://www.sciences.adelaide.edu.au/current-students/forms/savs-allowed-leaveofabsence-tute-prac.pdf.
Practical assignments: (10% of total course grade; 1% per practical)
During each practical class, an assignment will be set to be handed up at the end of that class. The practicals will be designed to provide training in key skills in sedimentary geology and geochronology as well as manipulation/analysis of geochemical and Earth system data. The practicals will reinforce the theoretical learning from the lectures as well as providing hands on context. One practical will involve field observation and interpretive skills. Another practical (week 7) will entail group presentations by students followed by debate on their chosen topic for Assignment 1, the objective being to stimulate thought and gain feedback from lecturers/peers prior to essay writing.
In-class theory tests: (45% of total course grade; 2 tests, 20% and 25% respectively)
Two tests will be given to address understanding of the lecture and practical material. The first test will be given mid-term to provide the students a benchmark for their progress in the course. The final test will be given at the end of the semester to ensure summative knowledge of course material. The tests will consist of multiple choice and short answer questions and be held during the lecture session in week 5 and the practical session in week 12. Feedback on the first in–class test will be provided by end of week 6.
Theory assignments: (45% of total course grade; x2, 25% and 20% respectively)
Assignments will be used to stimulate independent research, information synthesis and critical review of key topics within the discipline. They will provide experience and feedback in scientific writing and encourage a deeper conceptual understanding of the nuances of a specific scientific field. Assignment 1 will be preceded by a small group debate around the focus subject, thus encouraging verbal communication and group interaction skills. Assignment 2 is a take home exam consisting of four short summative essays on subjects covered in the course.
If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.
