Also, one of our TAs, Ian Leahy, has set up a weekly review/discussion section, Thursday 10-12 noon, in Duane D142.
END OF WEEK:
- We will work on grading the "long answer" exam question as soon as we can, stay tuned here for updates! (When we have the grades all put together, we'll put those up on D2L, and announce it here)
- If after carefully looking at the posted solutions you are convinced the Scantron misread your bubble sheet (this almost never happens, but...), please email Dr. Martins right away.
Week 6:
- Exam solutions are posted on D2L. (Under D2L: "Course Content -> Exam solutions")
Details about the histogram and class performanceare available under our usual "Course Info -> Exam Info" Tab.
Your individual grades are posted on D2L. (See the D2L: "Solutions and Grades" tab)
If you are unhappy with your score, please see this information/suggestion page.
See the "Course Info -> Grade Info" tab at the top of this page for details of how we compute grades.
Exams are only a portion of your grade (60% in the end, after we have had 3 midterms and a final, it's just 12% for each individual exam) What is much more important than your exam score is your "total course score" so far which includes lab, CAPA, and written HW. See the final row of your grade info on D2L to get an estimate of that. (I used your Exam 1 as a "proxy" for ALL future exams and the final to make this estimate right now. So at this point Exam1 is weighted as 60% of your grade, but by the end it will only be 12%)
- You will get your graded exam back in lab next week. At that time, if you feel that an error has been made by us in grading your written question, the procedure is: 1) Look carefully at the solutions! 2) If you still think there's an issue, please don't write anything on the exam itself after getting it back! Talk to your TA - they helped grade the exams and will know the "grading rubric" well. If at that point you still feel there is an issue, write up a brief note outlining the issue and give it to your TA, along with your exam. They will pass it along to Dr. Martins, who will look into it
- If after carefully looking at the posted solutions you are convinced the Scantron misread your bubble sheet (this almost never happens, but...), please email Dr. Martins right away.
- Take some time to understand anything you got wrong on this test - you may be retested on the same or related ideas later this term! Visit us in office hours, talk to your TA, ask on Piazza - get help early (and often!) That's what we're here for.

Prof. Martins wrote up a solution to the CAPA set 8 problem #1 .
After the exam: - Solutions to Exam #2 are posted, and your grades are now available on D2L.
See the Course Info -> Exam Info link for histograms of Exam 2 (nice high average, good work!) and "overall (estimated) course scores) (Also very high!)
Week 10:
- From class Friday: Falling magnet through a conducting loop. This comes from MITs E&M visualization resources, many other cool sims and visualizations available there. (Also see our Course Resources -> Useful/fun links page above)
- Due to a glitch on our part, CAPA #10's deadline did not got automatically extended (as we promise) from 11 PM Wed to Thursday@8 AM. I caught it in time on Thursday morning (thanks for the many email reminders!) and added an extra 48 hours. If you got shut out Wed night (or for that matter if you just didn't get to finish it and want another day or two!) you can still log in to CAPA and continue submitting on that set till Sat morning at 8 AM. Our apologies if this caused anyone stress Wed evening!
Meanwhile, Set #11 is available (due the Wed AFTER spring break) for those who want to get started on it, and is in the bins as per our usual schedule.
- Solutions to Exam #2 are posted, and your grades are now available on D2L.
See the Course Info -> Exam Info link for histograms of Exam 2 (nice high average, good work!) and "overall (estimated) course scores) (Also very high!)
Spring break:
- Enjoy your break!
Week 11:
- Welcome back! Hope you had a good break, and are re-energized for the next month of classes! There is a CAPA due (as usual) Wed evening, and written homework (also as usual) Friday after you return.
- From class Friday before break: Falling magnet through a conducting loop. This comes from MITs E&M visualization resources, many other cool sims and visualizations available there. (Also see our Course Resources -> Useful/fun links page above)
Week 12:
- Usual schedule this week. Exam #3 is coming up on Apr 16, we'll have more info on the exam link pretty soon.
Week 13:
- Exam #3 solutions are now posted on our D2L page.
We will be working on grading the last questions, and hope to have your grade info up on the web over the weekend, or by early next week. Stay tuned here, we'll let you know when more info is ready. (Average score on the multiple choice portion alone was just over 75%, nicely done! We'll put all the information up on the exam info link when we're done grading the written portion) - Exam #3 was this Thursday, Apr 16. See the usual Exam information link (In the "Course Info" tab above) for details.
Take a look at the posted clicker questions from the clicker question "table" link above - for Wed Apr 15 (Lecture 37) I added a half dozen more "review" clicker questions that we did not get to in class, but you might look at before the test if you want. They are at the end..
Exam 3 can include everything we have covered in lab, lecture, and/or homeworks up through Chapter 22 (EM waves). (So, Chapter 23, geometrical optics, will be on the final, not on midterm #3) As usual, our exams are always and inevitably cumulative (expect a bit of E-fields, voltage, and circuits) , but the emphasis is on newer material: expect to see magnets and magnetic fields, Faraday's law and EM waves, i.e. what we have done in Chapters 20-22, emphasized.

Prof. Martins will hold extra evening office hours Wednesday 04/15 from 5 to 6 pm in room G125. Bring problems you have struggled with and/or questions you may have about electricity! Let's have fun with Physics!!
Also, one of our TAs, Ian Leahy, has set up a weekly review/discussion section, Thursday 10-12 noon, in Duane D142.
All are welcome.
Week 14:
- Extra credit survey! Please fill out this survey. It counts as a small bit of extra credit (adds in to your clicker points) for you, is informative for this course - and I think you will find it useful to think about these questions!
- Exam #3 solutions are now posted on our D2L page. Individual exam scores are also posted on our D2L page. See the exams link for the class histogram and more information.
Final exam info is now posted at that link as well. See also the course goals link.
- Here is the PHET sim on converging lenses I showed in class. I find it quite instructive, play with it while doing this week's CAPA! And, here is the other sim with diverging lenses (in class Monday Apr 20)
If your browser won't run the PhET sim, try downloading it, and then "control click" the downloaded .jar file, to force it to run. It's safe, but browsers these days are super cautious about running java!...) And, here is the "wave superposition" sim I showed in class. More math-y, but nice to play with it, to get beats, standing waves, constructive and destructive waves, etc... I recommend "Example 3" in the left hand window. (Here again, you may have to modify your browser settings to allow it to run)
Week 15:
- Final exam seating! Please see this map for the seating arrangment in Coors for our final.
This, and more Final exam info is now posted on the exams link. See also the course goals link.

(Here again, you may have to modify your browser settings to allow it to run) And one more, the "slit interference pattern" sim I showed in class Monday Apr 27. I especially like this last one, it's simple and very helpful in helping visualize the 2-slit formula...
- A student in our class sent me an email that I thought might interest some of you:
" GlobeMed is a student-run nonprofit that aims to educate students about global health inequities and provides students with a platform to make a sustainable impact. If you're interested, check out our website: http://globemedcu.org/ .
Currently, we are selling discounted Kaplan MCAT prep courses to benefit our partner organization in Nepal"
End of term:
- Final exam is graded. Please see D2L for your score, as well as your total course score and letter grade. (The final exam histogram is on our usual exam link)
We have submitted grades to the CU registrar system.
Some people are asking about extra credit points from clickers. Please read the "Grades" link here or above carefully. Before emailing - look at the formula we use - this has been posted all semester. In particular, the clicker bonus points is a little subtle - see the formula and figure it out! (Clicker points are NOT just added directly to your course score)
Important: If you think a *clerical error* has been made in your grade, contact Dr. Pollock or Dr. Martins immediately. This means e.g. if some assignment did not get properly recorded, something like that. If you simply want to request a change of grade for any other reason - we are sorry, but please see the "Grades" link here or above. Our spreadsheet is well-checked, we are following our stated, objective grade calculation rules. And one more comment- there is of course no mechanism for special favors (or extra credit at this point), please don't ask, thank you!
Thank you for a great semester!
