End of the year info May 14, 2008

Seniors, if you would like to to know your exemption status, the names of those exempt according to grades earned in my class has been submitted to the office for an attendance check.  If you just can’t wait to find out from them, send email to bergerj@delphi.k12.in.us with the subject line “AM I EXEMPT?” and I will let you know.  That way, if you have any questions about your status, we can deal with them in a timely manner.  I realize some of you have some work you are doing with Mr. Thompson, and this will be included in your final grade, but is not eligible for exemption status as of now because those names had to be turned in today.  You will get credit for the work you have done.  If you are not exempt, material from second semester is fair game for your finals and review sheets will be posted here soon for each class.

 

Significant Digits Reminder January 10, 2008

Filed under: Chemistry, Physics — Mrs. Berger @ 10:20 am

Remember that significant digits are important because they help to reflect the precision of the instruments used to make the measurements involved in a calculation.  I have posted about this before with some websites you can use to help you practice.  The second website is actually quite good and has a lot of practice for you to try.  The third website, I think, has been removed but the other two are fine.  If you have any questions after doing these tutorials, please feel free to comment, even if you are not one of my students!

First Day of School - Welcome August 14, 2007

Filed under: AP Chemistry, Applied Chemistry, Chemistry, Chemistry I, Physics — Mrs. Berger @ 7:51 pm

I know you all are adjusting to being back at school, but so are the teachers.  We have many new things to work toward this year, and I am very excited to get started.  Hopefully your time in my class will be a rewarding and educational experience, and we will try to have a little fun while we’re at it.

 

Seniors that are Exempt from Finals May 16, 2007

Filed under: Applied Chemistry, Chemistry I, Physics — Mrs. Berger @ 2:49 pm

Here is a list of all seniors exempt from my finals.  If your name appears, congratulations, you do not have to take finals.  If your name does not appear, your current grades or absences have removed you from the list and you are required to be at the review session on Monday and be here to take my finals Tuesday and Wednesday.  If you have any questions about this, please see me.  A few people are very close to being exempt, so these people may have their names added to this list, but if your name is already here, you are locked in as safe, as far as I am concerned.

  1. Joanna Zink
  2. Daniel Butler
  3. Nick Force
  4. Shannon Kremer
  5. Britney LaFollette
  6. Keltie Lake
  7. Caitie Pritchett
  8. Brianne Stauffer
  9. Tom Walton
  10. Kris Anderson

Square waves for Daniel March 15, 2007

Filed under: Physics — Mrs. Berger @ 9:27 pm

Daniel asked today about square waves, and I thought that was kind of a “square” question.  It bothered me all day, so I went looking for some more info on the subject.  I found some good stuff at Wikipedia, of course.  I will add more if I feel like it. :)
