HON CHEMISTRY – Good luck studying for your test! Here’s the overview of the test on chapter 2 from today. Remember, don’t just read your notes – practice your notes, practice the problems, practice the memorization!! If you haven’t had a chance to print them out, here are links to the study suggestion sheet and the chapter 2 formula sheet. Click on the names below to open – but change the prefixes you need to memorize to Tera through nano.

Also, don’t forget sciencegeek.net and the online review quizzes that you’ll find under Chemistry Tutorials below. Good luck studying! Help session tomorrow morning (Friday) at 7:15 A.M. I’ll be praying for you!!

I can’t find where to go to find the Graphing Exercice 2. I’ve looked on edline and this site, and apart from me not seeing “Making Science Graphs and Interpreting Data”, then only “Graphing Problems” link leads to the Graphine 1 questions. If you would provide a link, or some information on how to get to Graphing Exercise 2, that would be great.

Thanks in advance.

Evan – Check out where you were last night. Go to the Graphing Helps link under “Chemistry Tutorials” over on the right. Follow the instructions from Exercise 1 to get to the bottom of the

“Making Science Graphs and Interpreting Data” page and at the bottom, under “Graphing Problems,” you should see the link to Oxygen Production graph.

Oh.

Thanks!

I looked on edline to find the lab manuscript form but everytime i would click on the link it would say that my account has been unactive for a while and automatically logged out. I tried it about 5 times and finally just went to this website and I luckily found it. So thank you for putting the link on your website as well as edline!

Rebecca – I’m so glad you were able to find it! Thanks for not giving up!! 🙂

My computer will not let me view this video. It says, “Sorry, this episode is temporarily unavailable. Please try again later”. Is there something I can do to fix this or is a server problem?

Luke – I’m not sure what the problem is. I’ll try to check it out.

Luke – I just tried it and it played for me. Did you try closing the website and opening it again?

I don’t think I completely know the rule for uncertainty. I know that last digit of a measurement is the uncertain number, but what is the rule for how high or low you could guess? Did it have to do with how many places the intrument you were using went to?

Hope – It varies, but in general (and this is what you need to know), it’s half of the last mark on your instrument. So if the last mark is tenths, then the uncertainty will be 0.05

Ms. Skinner, on the table of data for oxygen production, is the volume of oxygen measured by total volume of the gas at that set time or by how much was produced that minute?

Adam – It’s the total amount produced by that time. Graph??? Are you studying for your test??????

Yes mam, I have been studying and reviewing over material. I decided to do this as a review.

Adam – Good job!

I want to know if the conversions between Celsius and Fahrenheit will be on our test tomorrow, AND I’m not sure I completely know the rules for what types of digits are NOT sigfigs. I know the digit rules like leading zeros etc., but I couldn’t find in my notes thew exact rules for those digits.

Will – Anything we covered in class, including temperature, may possibly be on the test. However, since you asked, if you have to do a conversion, it will most likely be Celsius to Kelvin. On the sig figs, did you watch the vodcast? NOT sig figs are all leading zeros and trailing zeros without a decimal in the number.

Mrs. Skinner thank you for putting out a good sites to help us study for this test. i hope to get to the help session tomorrow. Thanks again.

If we had to redo our graphing homework, do we copy everything (including non graphing problems)on graphing paper or leave problems on regular paper and copy the graph onto a sheet of graph paper?

Anyone want to answer this before I do?

Luke – You just redo the graphs on graph paper. You can leave the problems on notebook paper.
