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.

Density Bottle Project September 4, 2007

A few students have asked, “What do you mean by the term liquid?”  The Chemistry I Density Bottle Project requires at least four different liquid layers.  I think this leads us to exploring the definition and discussing the properties of this state of matter.

According to dictionary.com and the American Hertiage Dictonary, a liquid is the state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility.  Therefore, in order to qualify as a liquid for this project, the substance must flow, not evaporate into vapor readily and be incompressible.  (this means you can’t smoosh it into a smaller space) 

 Some have asked, “Can I use water with things mixed in to change the density?”  You can try this yourself, but think this out.  If you mix salt with water and if you mix sugar with water, when you pour this into the same bottle, since they are both water, won’ they mix?  Think about substances that don’t mix with water.  Maybe you want to try these.  Maybe you want to check out some properties of water according to the US Geological Survey’s site on water.  This  might help you decide whether or not to even use water.

First Day of School - Welcome August 14, 2007

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

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
11. Valeria Bautista
12. Jacquelynn Richardson

Would you like a spot of tea? (hold the moo juice) January 9, 2007

I just read this article done on the effects of tea on the prevention of cardiovascular disease that was really interesting. They found that when you add milk to the tea, the effects are decreased because of an interaction of the proteins in milk with the flavenoids in the tea.  The chemical and biological research that is being done is amazing - and they are just studying tea!

Also, for any of you in Chemistry I getting ready to start on your Periodic Table Project, here is an article on fluoride that might be of interest if you are assigned the “Halogens” for your task.
