Unformatted text preview: EAS 111 General Announcements 12/6/10 • • • • Today: Exam 3 results and discussion Grade calculation and the final exam Review for Lab Exam 3, again Final thoughts about the earth sciences and EAS 111 relative to your world • Lab Exam 3 this week – end of the lab course • Final Exam open review Weds.,12/8/10 2:30-3:20 • Last round of office hours Tues., 12/9/10 3-4:40 • Final Exam 12/13/09, 10:20 AM-12:20 Right Here Exam 3 Results N = 150 Mean = 76.9 (!) Median = 78 (!) Max = 100 28 people ≥ 90 (!) Lecture Results –Scaled Results N = 159 Mean = 76.7% Median = 78.8% Max = 100.6% Actual Max Points = 343 Scaled Max Points = 330 Lab Course Results without Lab Ex.3 N = 161 Mean = 248(!) Median = 259(!) Max = 292(!) Current Max Points = 300 Actual Max Points = 340 Likely Scaled Max = ~320 EAS 111: Figuring out my grade So how do I figure my running course grade? Should I take the Final Exam? 1. Lab score/Lab max = X/300 (*currently*, will be x/340 after Lab Exam 3 is done) = ? 2. ? x 0.4 (40% of your course grade) = ?? 3. Scaled Lecture score = Y/330 = ??? (on BB) 4. ??? x 0.6 (60% of your course grade) = ???? 5. ?? + ???? = your running course grade percentage Example: I have 264 lab points and 292 lecture points 1. 264/300 = 0.88 2. 0.88 x 0.4 = 0.35 3. 292/330 = 0.885 4. 0.885 x 0.6 = 0.53 5. 0.35 (lab) + 0.53 (lecture) = 0.88 = 88% = B+ 6. maybe an A- with a good final and good lab exam? EAS 111: Final or no final? •The final is cumulative – broad but not deep •It is a one hour exam, but you have two hours to take it •You’ve seen all the material in this exam before •If you have failed or otherwise done less well than you’d like on any lecture exams, then take the final •Your improvement over any previous lecture exam score will be credited to your raw lecture total •If there is no improvement, your score stays the same as it is now – you have nothing to lose •Office hours for one-on-one help – this week Tuesday (tomorrow) - 3:00 PM - 4:30 CIVL 2285a •Open review Wednesday, right here, normal class time. •FINAL: right here, Monday 12/13, 10:20 AM-12:20 PM Lab Exam 3 Review (again) M Lab Exam 3 Review Tips You should be able to: • Read a topographic map and construct a topographic profile • Reason from topographic features and profiles to make conclusions of their likely origins – i.e. which physical processes were likely most responsible for generating the features you identify? • Basic ID of earth material – is this rock sedimentary, igneous or metamorphic? What does it mean that this assemblage of rocks is here in this condition (rounded? sorted? etc.?). Think about what you did at Stop 1 during the field trip. • From any set of evidence, be able to construct a set of possible origins, and then reason toward likely origins – just like you’ve been doing in the labs and on the field trip. • Be able to synthesize all of your observations and conclusions to provide a coherent and reasonable narrative of the sequence of geologic events that led to the current landscape. • Read a topographic map and construct a topographic profile • Reason from topographic features and profiles to make conclusions of their likely origins – i.e. which physical processes were likely most responsible for generating the features you identify? • Understand how these physical processes will progress and likely potential hazards for human structures Earth and Atmospheric Sciences 111 Fall 2010 Humans and Planet Earth -Where do we go from here? -The major challenges ahead. The consensus from all people involved in earth system science -AGI transition document -Lecture 22 The Road Ahead Critical Needs for the Twenty First Century: The Role of the Geosciences A consensus document of the 47 member societies of the American Geological Institute http://www.agiweb.org/gap/geotrans08.pdf #1 Energy and Climate Change • How do we secure stable energy supplies in an increasingly carbonconstrained world? • Fossil fuels vs. renewables • Domestic production vs. foreign imports • Infrastructure, development, impacts Our Energy Mix U.S. Energy Information Agency #2 Water • Will there be enough fresh water and where will it come from? #3 Waste Treatment and Disposal • Capacity • Preventing long-term build-up of toxicity • Recover valuable materials, sequester dangerous ones #4 Natural Hazards • How will we mitigate risks and provide a safer environment? #5 Infrastructure Modernization • Bridges, roads, dams, levees, drains, etc. Sounds trivial, but imagine life without all this… #6 Raw Materials • How will we ensure reliable supplies when they are needed and where will they come from? #7 Geoscience Workforce and Education • Who will do the work to understand Earth processes and meet demands for resources and resiliency? • Who will educate the public and train the workforce? Parting Thoughts • I hope you understand much more that before how the earth sciences are relevant to your world • I hope you understand how your discipline/major are involved with the Earth Sciences • I hope you all have learned from this material and prosper from it • I hope you’ve had as much fun here as I have!
