Final Exams

Hi folks,

I forgot to mention that I'll be happy to send you the final exams if you wish.  Just let me know and send me have your mailing address and I'll send them out next week.  (I'm on vacation until this coming Sunday.)

I hope you're all having a wonderfilled summer!

End of Year Chemistry Syllabus

Hi folks,

I've enclosed a full overview of everything we covered in this year's chemistry class.

No homework for Science Jim's Classes this week!

Hi folks,

No homework for biology and chemistry this week.  Just study study study.  Best way to do it is to look over ALL those old quizzes.  The test will be based on the old quizzes and anything that's on those quizzes is fair game for the final.  I'm trying to make the final about 1.5 hours long so you may want to have a ride on call in case you finish early.

If you have any questions you want help with don't hesitate to let me know.

Here is the biology blog if you want to look over old recordings or assignments.

Here is the chemistry blog if you want to look over old recordings or assignments.

Good luck everyone!

Bit of help with this week's homework

Another thing to look at for this week's homework is electroplating. This may help explain what's happening to the paperclip...or...it may not... :) It's up to you to come up with logical explanations to explain what observations you made during the experiment. Good luck!

Review

Hi folks,

This would be a good week to spend some time looking over old quizzes.  Are there any problems or concepts that you are struggling with?  If so, bring them to class.  We can spend some time working through the problems.  Stoichiometry, heat calculations, balancing, naming etc.  It'll all be on the final so now's a good time to take a look to see if you need some help.

5/10 Chemistry Update and Homework Due 5/17

Hi folks,

Today was a busy day with two labs and a discussion of reaction rates and endothermic vs. exothermic reactions.  We took a look at just how much water, salt and sugar is in a mole and we also did electrolysis, one of my favorite labs.

Homework for next week is to:

Read pgs. 279 - 300 Don't worry about the #'s and the math.

Investigate electrolysis and create a report telling me:

1. The chemical reactions taking place within the experiment.

2. Why do you think the water changed color?

3. What do you think happened to the paper clip?

4. What do you think happened to the water in the test tube?

5. Why did we need the battery?

6. Why did we need to use salt water?

4/3 Chemistry update and homework due 4/10

Hi folks,

Today we did a rather wacky lab to try to get a better feel for chemical equations and the concept of stoichiometry. No recording this week since we just did the lab for the entire class.

Homework for next week:
Most of you finished some of this in class but I'd like you to hand in...

1. How many moles of borax did you use?

2. How many moles of glue did you use?

3. How many moles of water did you use?

4. If you wanted to create 1000g of silly putty, (and we all do) how many moles of Borax would you need?

5. How many moles of water would you need?

6. How many moles of glue would you need?

7. If you wanted to create 1000g of silly putty, how many grams of Borax would you need?

8. How many grams of water?

9. How many grams of glue?

(You read about these laws way back in January. They are in chapter 3 if you need review.)
10. This experiment is also a great example of the Law of Conservation of Mass. Tell my why it's such a great example.

11. Not only is it a good example of the Law of Conservation of Mass but it's also a great example of the Law of Definite Proportions. How does this experiment illustrate the law of Definite Proportions?

Extra Credit for Chemistry

Hi folks,

A small extra credit opportunity here for you.  5 points if you can figure out what the common "I can get this at the store" items are for the chemical formulas in this grocery list.  I must admit, I'm not sure what #5 is either so you can skip that if you want.  Good Luck!

Change of classroom space

Hi folks,

I'm sorry for the confusion before.  ALL classes will be held at this location from now on.  Sorry that that wasn't clear.

New Location for Biology!!!

Hi folks,

Remember that location that fell through for us earlier in the year?  Well it's available now and I'd like to start using it for classes this week.

The location is at 6901 Turkey Farm Road Chapel Hill,  NC 27514.  It's on the way to my house but you take a left on Turkey Farm road (assuming you're coming from 86) and it's about 500 ft on the left hand side.

I hope this doesn't cause any inconvenience.  See you all soon!

4/26 chemistry update and homework due 5/3

Hi folks,

Last week we spent time getting deeper into moles and talking a look at stoichiometry. It's quite intimidating at first but hopefully it will be easier with practice.

Homework this week:

Do questions 5-8 on the enclosed .pdf. Check your answers carefully and really try to get comfortable with this.

Re: 4/19 Chemistry update and homework due 4/26

Hi folks, 

Karan caught a typo.  In the second question #5 on the "Complete and Balance" sheet BaCl should be BaCl2.  Sorry folks and good job Karan!

Is number 5(second number 5) balanced?  The answer  shows 1 'Cl'  on the left side and 2 'Cl' s on the right side.

Hi folks,

Today we covered three topics.  The 5 different types of chemical reactions, how to predict reactants from products and we began working with moles.

Homework for this week is to do the enclosed two question sheets.  Both have answers so that you can check your stuff and really get the hang of this.  Really try to get comfortable with the mole concept.   We are going to be doing quite a bit with that in the next class or two and the more comfortable you are with it now, the easier it will be.

4/12 Chemistry update and Homework due 4/19

Hi folks,

Today we reviewed naming a bit more and started working with balancing chemical equations.

Homework for this week is to do the following .pdf. Answers are included (good ones this time :) ) so that you can check your answers.

Home work sheet

Hi folks,

I missed the fact that the sheet has a bunch of polyatomic ions that I didn't ask you guys to memorize.  When you come to the problems with those, either (a) google them or (b) skip them.

Sorry about the frustration on that.
