Chemistry 101

 

 

 
bulletWelcome to Chemistry 101.  If you do not already have one, you will need to go to Computer Services (help desk, Admin 133) and get a University Computer Account set up immediately.  This account is necessary in order for you to have access to our web site from campus computer labs.  They can be reached at 885-APAL or by email, helpdesk@uidaho.edu  I can be reached at fletcher@uidaho.edu.

 

bulletTuesday, May 13.  The Final Grades are now posted on the university website.  If you see a grade that doesn't seem right, contact me by email and we can try and get it straight.  It's surprising the number of people the extra credit put over the pass line, but I hope you realize you dodged a bullet.  I know you can do better!  About 12 of you received an A grade and congratulations to that group.  Approximately the same number received a D grade.  About double that number received a grade of B and the majority of the class received C grades.  To those who failed, it mostly came down to missing an assignment or two and generally low grades on the exams so I couldn't add in the lab.  Remember, if you completed and passed the lab portion of the course but failed the lecture part, you can take the course again without redoing the lab.  If you go that route, you need to enroll in Chem 101 under Section 40.  I hope you all have a great summer!

 

bulletFriday, May 9.  Hello?  Hello?  Anybody out there?  I now have the grades up for all the homework, the hour exams and the final.  You  can check them at the "Get your Grades" page.  If you don't see a score it is because I didn't receive it.  Send me an email if you see things differently.  You can contact me at fletcher@uidaho.edu.  I still not have the lab grades and I might not get them until Monday.  Do not worry.  Your grade will be recorded when I get all the data.  We are not even late until Tuesday at midnight.  For those of you on the borderline for passing, you have enough information here to find out if you passed the lecture part of the course.  Remember, you need 324/600 = 54%.

 

bulletThursday, May 8.  I graded the exams this morning.  The average was 58% or 116/200 points, which is dangerously close to that 54% cutoff for passing the lecture.  I hope few of you will be surprised by an unexpected grade but I've already added points to everyone's score, plus the extra credit.  Nobody scored perfectly but there was one score of 96% or 192/200.  I was surprised at the low average since over a third of the questions came off the old exams or homework.  I will now go to work getting all the grades together but it will be slow.  I will try my best to be finished by Friday afternoon.

 

bulletWednesday, May 7.  The Answer Keys for the Final Exam are available for downloading.  You can find them on the Exam page.  I will correct the exams tomorrow, Thursday, and post the average.  I will then begin to work on assembling all the grades and put them up on the Check Your Grades page.  I will place an announcement on THIS PAGE when the grades begin to become available.  If you don't see an announcement here, don't panic.  There are no changes!

 

bulletFriday, May 2.  I've got a computer set up and running for now and I've recovered everyone's grades.  The answer key for HW 4 is posted and you can find it on the Homework page. 

 

bulletWednesday, April 30.  Mea Culpa.  Problem 25 on HW 4 doesn't seem to have a correct answer.  I got my inequalities turned around on answer D.

 

bulletWednesday, April 30.  The "Get Your Grades" feature seems to be working.  Make sure you follow instructions to create your password and that you do not use a hyphen in your ID number.  I have not yet entered the scores for HW 2 and 3 but you should see the correct numbers for Exam 1,2 and 3, HW 1 and Extra Credit.  Send me an email if you see problems.  You can find the Get Your Grades on the Grades page.

 

bulletTuesday, April 29.  Ok, figured it out.  I can't get the scores up tonight but I will do it in the morning.  Sorry for the delay.

 

bulletTuesday, April 29.  Looks like I failed getting your scores up today.  I have all the scores loaded but I cannot get your ID numbers to save correctly so the software can recognize them.  This means that the Get Grades page is still not working so don't even try.  I will get some advice on this on Wednesday and hopefully get this working.  If you want your scores before then, you can ask after class or come by my office.

 

bulletMonday, April 28.  The Homework assignment 4 is now available to be downloaded.  You can find it on the Homework page.  Also, there will be a help session Wednesday night in Ren 127 at 6:30 pm

 

bulletWednesday, April 23.  No class on Friday, April 25 to make up for the exam Monday night!  See you Monday to finish Chapter 12.  Review starts on Wednesday.  Also, we will have a help session tonight (Wednesday.)  Room 127, 6 pm.

 

bulletFriday, April 18.  In class today, I offered a way to generate some extra credit points.  On Monday, anyone who turns in a Haiku poem meeting certain requirements will get 10 points.  The Haiku must follow the standard 5 syllables, 7 syllables, 5 syllables format and each line must contain an elemental symbol from the periodic table in a word.  You cannot simply use the symbol as an abbreviation for the element.  The symbol must be in a word.  You must type out your entry (no emails) and turn it in Monday in class.  I will choose the top 10-20, present them in class and then the class will vote.  The top two selected will receive an additional 10 points.  An example of what I want is shown here (with the exception that roar might not have two syllables!  Hey, I wrote it 10 seconds before class and I don't need the extra credit!)  Yours must follow 5, 7, 5 format and cannot be dirty.  I have to put it on the board! 

 

bulletMonday, April 14.  The Answer Keys for hour exam 3 are available.  You can find them on the Exam page.  The average is low again at 55%.

 

bulletFriday, April 11.  The answer key is now available for Homework 3.  You can find it on the Homework page.

 

bulletTuesday, April 8.  Mea Culpa!  It seems the Homework 3 did not get posted on Monday by 5 as I promised.  I made a rookie mistake.  I posted the Homework and it looked fine on my computer but I guess I neglected to "save" the page once I put it up.  I am pretty sure I "pushed the save button" but I guess I didn't.  I should have checked on the live web page but I didn't.  I apologize if this caused any inconvenience and I appreciate the notes I received from those who let me know.  Thanks and I hope this HW helps you prepare for the exam.  You can find HW 3 on the Homework page.  Remember, we will have a help session in Ren 127 at 6 pm on Wednesday evening.  See you there.

 

bulletMonday, March 17.  Exclusive to Section 4.  My bad!  Somehow, the midterm grades got posted for all sections but 4.  I don't know if I didn't push the right button or if the data base failed or what, but I apologize and I hope it didn't cause any problems for you.

 

bulletMonday, March 3.  The Answer Keys for Hour Exam 2 are now up so you can score your exams.  The average is low on this exam, at 57.  You can find the Answer Keys on the Exams page.

 

bulletSunday, March 2.  Oops!  I made a mistake on the HW 2 Answer Key that several of you caught and sent email about.  Thanks for that.  On problem 18, the correct answer is that Group I are the alkali metals, NOT the noble metals.  In fact, Group I is very reactive!  Also, remember that Hour Exam 2 is Monday evening.

 

bulletSaturday, March 1.  The Answer Key for HW 2 is posted.  You can find it on the Homework page.

 

bulletSaturday, March 1.  We have finally been given a date and time for the Final Exam.  The time and date can be found on the Exam Schedule page.

 

bulletMonday, February 25.  Just a reminder that we will be meeting for a Help Session tonight at 6 pm in Room 127.  Also, Homework 2 is now available for downloading.  Oh... the "Check Your Grades" is still not working so don't bother trying!  One more thing - remember, Exam 2 is scheduled for Monday, March 3.

 

bulletMonday, February 11.  I'm still working on pinning down a date for the second exam.  I should have a date on Tuesday.  For now, this might help.  Or not.

 

bulletMonday, February 4.  The Answer Keys for Exam 1 are now available from the Exam Page.  Download the appropriate version (Version A, B or C) and grade your performance.

 

bulletFriday, February 1.  Hey, didn't we just miss class?  Yes we did!  Again, UI classes were cancelled so HW 1 was not due today.  The way we will handle this is that I will gift every one with a score of 25 on this HW.  I'll assume you worked your brains to mush and you would have scored perfectly.  Actually, I do this so I can put up the key.  The Answer Key is up. You will find it on the Homework page.  Please use the weekend to study Chapters 1- 3 and the prologue because Exam 1 is still going to be run as scheduled.  Monday night, 7 pm.  We will be in class on Monday (I hope!)

 

bulletMonday, January 28.  Reminder that there is a help session tonight, Monday, in Renfrew 127 (or close by) that starts at 7 pm.  Stay as long as you like, leave when you like.

 

bulletSunday, January 27.  The first Homework assignment is available to be downloaded.  You can find it on the Homework page.

 

bulletMonday, January 14.  This week we'll be working through Chapter 1.  The rough schedule will be Monday: Measurement (Sections 1 and 4), Wednesday: Scientific Notation (Section 3) and Significant Figures and Uncertainty in Measurement (Section 2), Friday continues this and goes on to include Temperature (Section 6) and start Unit Conversions (Section 5.)  We'll try and finish up the section on Unit Conversions by next Monday and begin Chapter 2.

 

bulletMonday, January 7.  Please get in the habit of checking these announcements regularly.  I will put any additions to the lectures here and news important to the course.  For example, if an exam date must be changed, I will make an announcement here.
