A practice final exam to give you an idea of what to expect Tuesday. While I may make small changes to questions from previous exams, and will include 3-4 new questions covering cosmology, the practice exam should closely reflect the topics and difficulty of the final. Good luck! And see you Monday evening for the review.
While it's worthwhile looking up and figuring out answers for yourself to prepare, here's the answer key to the practice final exam: 1. b, 2. a, 3. e, 4. d, 5. b, 6. e, 7. e, 8. b, 9. d, 10. d, 11. d, 12. e, 13. d, 14. b, 15. c, 16. a, 17. c, 18. e, 19. e, 20. e, 21. e, 22. e, 23. c, 24. b, 25. d, 26. a, 27. b, 28. c, 29. c, 30. a, 31. d, 32. d, 33. c, 34. e, 35. d, 36. b (and the question should be "setting at" withing that confusing word "rising!"), 37. a, 38. d, 39. e, 40. c
Not everyone saved their first exam, so here is that file for you. Here is the answer key.
There will be a review session for the final exam on Monday evening, 6:30pm, in PS 234 (same room as last time). Final exam questions will be drawn from tests/practice tests 1-3, plus a few questions about cosmology. A practice final will be posted here, but probably not until Saturday.
Grades going into the final will be distributed Thursday in class. They are out of 100% (in the final calculation they will be 85% of the total grade and the final exam will be 15%, so your final grade will be the preliminary grade x 0.85 + final exam grade x 0.15). If your final exam grade is higher, your score will go up. If your final exam grade is lower, it will go down.
Exam 3 is graded. Average was 67%, so we'll have a 3% curve to move that up to 70%. Add three points to your raw score.
Practice exam 3 is ready for you now here. I will be happy to discuss answers in class and in the review (Wed. evening at 6pm in Physical Sciences (PS) 234, AKA the "Prowse Room."). Answer Key: 1.b 2.e 3.e 4.b 5.e 6.d 7.a 8.b 9.e 10.b (repeat, sorry) 11.a or d (sorry -- bad question) 12.d 13.e 14.d 15.d 16.c 17.c 18.a 19.e 20.b 21.d 22.e 23.e 24.e 25.d 26.d 27.d 28.d (got to watch those d answers!) 29.b 30.d 31.b 32.c 33.c 34.a 35.e 36.c 37.c 38.d 39.e 40.b Topics to be covered: Light (electromagnetic spectrum, black bodies including Wien's Law and Steffan-Boltzmann Law), Stars (H-R Diagram, OBAFGKM, composition, distances, colors, temperatures, luminosities), Stellar evolution (protostars, evolution onto main sequence, off main sequence, planetary nebulas), Stellar End States (white dwarf, neutron star, black hole), Milky Way (size and structure, Cepheid variables, spiral arms, mass and dark matter), other Galaxies (types, clustering, Hubble's Law), active Galaxies (quasars, supermassive black holes, gravitational lensing).
Exam 2 is graded and being returned. It was harder than I expected, with a 65% average, so I will add a 5% curve. Add 5% to your raw percentage score.
Here is practice exam 2 and the answer key. I am traveling, but may be able to answer questions via email. You can also go to your lab instructors for help in advance of the exam.
I have submitted mid-term grades based on your first exam scores plus an average estimate of typical lab and attendance scores. This is probably slightly optimistic. If you scored in in the low 20s (out of 39) on exam 1, score very low on labs, and do not attend class regularly, I may not have indicated an appropriately low mid-term grade and I ask you to be aware if you fall into this category.
Exam 2 on Tuesday 10/23/2012 will only cover solar system and exoplanets material since the last exam. Light will be included on a future exam, where it fits better and merges into stellar properties.
A new exoplanet was found by planethunters.org, a project that lets web surfers examine Kepler data. Cool! Try it yourself!
Here is the (answer key to the first exam if you want to check and see which answers you got wrong.)
The section that meets at 2:45pm in CR 214 will MOVE on Thursday, 9/27, to AG 1032. This room should work better for us in several respects. See you there!
We have an exam next week, Tuesday 9/25, in class. BRING: a blue, 5-answer bubblesheet, a pencil, a calculator. Here is a practice exam to help you study (answer key). (Note: The answer key is wrong for question 26: the correct answer is "b" not "a." Also, yes, questions 34 and 37 are the same, by mistake, with a weird answer d. I'll be more careful with the actual exam!)
