#1 --Please finish your lab worksheets from class.  The solutions are printed in the teacher portion of the lesson.  If you need more help understanding mole conversions, see your textbook, chapter 6.4, or a video-tutor like http://socratic.org/chemistry/the-mole-concept/what-is-a-mole -  see the bottom of the page (chapter 15).   See also below.

#2 --Learn the Song!  and think of some good ideas for taping it {I have this cool lamb puppet, which could sing "Baaaaaaaaaaa-rium is 56..." --I will bring my lamby, plus some hellium balloons, some glow in the dark face paint..}  Anyone got a Frankenstein mask?  leave comments with ideas.

#4 --Covalent Bonding - naming practice - When a metal binds to a non-metal, it's ionic, but if two non-metals bind together, it is a genuine molecule with  covalent bonds, and it has a different and simpler method of naming.  Print out pages 10-11, read the directions and fill out the worksheet.  http://academic.pgcc.edu/~bsuitte/chem%201010/Nomenclature_Worksheets%20covers%20all.pdf

Congratulations -- we have done a lot of groundwork for success in chemistry, and hopefully it will get more and more interesting as time goes on and our knowledge base grows.  Good work, all round!


EC for IQ- Can you figure this one out?  (using dimensional analysis, factor-label, 'nother name for one, whatever you want to call it...)

Cardiovascular diseases are the leading causes of death worldwide.  To address this problem, bio-medical engineers have designed various artificial hearts, which surgeons may someday routinely implant in patients whose own hearts are failing.  Before implanting such a decide in a patient, a surgeon needs to have an idea of how long the artificial heart might be expected to work before needing to be replaced. If an artificial heart is capable of pumping at least 17,000,000 pints of blood before failure, how long will it probably last in a patient whose average heart rate is 72 beats per minute, and average stroke volume (the amount of blood pumped each stroke) is 70 ml?   [hint: there are about 473 mL per pint, and strokes are the same as heartbeats.]

1.  Plug in the value that you start with.
2.  Determine what unit you want to end up with. (how many years?)
3.  Write down any ratios that you are given.
4.  Write down any conversion factors that you might need.
Then make an extended t-chart.  Write your answer in comments.
Prize will be CANDY!

Holy Moly, Batman...

Thinking about our class->>>I would like you to go over the worksheets on unit conversions that we did in class: the pencil in miles, the paper clip in tons, etc.   Finish what you didn't complete in class and NEATLY, very neatly, write out the equation as it is supposed to be done, with the units clearly expressed, and no shortcuts.  [If grams are in the numerator, then put grams in the denominator of the following conversion/fraction...
]. Then think about the answer, does it make sense?  If your pencil is 32,000 miles long, or your paper clip is more than a ton, my guess is you made a mistake.  If you would like to print a new copy, go to page 9 here: http://misterguch.brinkster.net/17.pdf  (Unit Conversion Lab)  Answers are provided.  Please turn this in on Monday, neatly, so I can grade it.

T'S AN IONIC CONTEST!   More naming ionic compounds, but here's the twist, time how long it takes you to complete page 1 only, just the naming part. [start by making a cheat sheet in the margins.]  Leave a comment with your score below.  Then finish up the worksheet; you also have to figure molar mass.  See textbook chapter 6.4 (page 165) for instructions, and you only need to figure the molar mass for the even numbered 1-20.  But to be clear, do the ionic naming both pages.  Are you getting good?  Tickets for participating in the contest; if you can beat my doubled-time, I'll give out a prize. :}  http://misterguch.brinkster.net/WKS001_023_749153.pdf  (answers provided.)

WEDNESDAY'S HOMEWORK...#happymoleday

6.02 x 10 ^ 23

[Professor Avagadro taught Defense Against the Dark Arts at Hogwarts, I think. ]

Happy Mole Day!              

and I cannot help myself...


If you did not do TUESDAY's homework, see post following this.

And watch/practice the Conversion Factors, by Tyler Dewitt: (what I should have taught before we did moles)
http://socratic.org/chemistry/measurement-in-chemistry/unit-conversions/converting-units-with-conversion-factors  Watch enough to do this worksheet:
http://woodridge.k12.oh.us/ourpages/users/dweaver/Chemistry/PracticeWorksheets/CalculationWorksheets/UnitConversionsWorksheet.pdf  yea! there are answers to check your own work. 

TUESDAY'S HOMEWORK : hints for remembering polyatomic atoms

Please NOTE: I will post WEDNESDAY's homework tomorrow.  

  Watch the first half for some review, but skip the rest    when it goes to acid-naming; that's for much later.

Take notes ALWAYS; in order to retain any of this you must take notes. Remembering starts with a pencil. 

 

Take notes here; in order to retain any of this you must take notes. Remembering starts with a pencil.

If you are wondering which polyatomic ions to memorize, this is the starter list:
 hydroxide, nitrate, nitrite, sulfate, sulfite, carbonate, phosphate, ammonium.  

and so now for a worksheet to practice and before you proceed, write down all the tricks you learned at the bottom of the page. with... http://misterguch.brinkster.net/WKS001_010_636149.pdf
You will be glad to know there is an answer sheet!
PLEASE RETURN TOMORROW FOR MORE HOMEWORK!

I (go) On, and ion and ion...

Print out this periodic table of ions:
http://www.sciencegeek.net/tables/PT_ions.pdf


I know I gave you homework pages copied from the textbook, but if you would rather finish out this set of worksheets [purple link below], that would be better, and would be easier to correct, and would take less time. You should already have done the first 4 pages (2 worksheets) last week; now you should complete worksheets 3,4 and 5. It is 12 pages total, you've done the first 4 pages, so print out pages 5-12, and it includes instructional help. Unclear? call me.
http://academic.pgcc.edu/~bsuitte/chem%201010/Nomenclature_Worksheets%20covers%20all.pdf   ***There is a really good shortcut rule on the last page-- called the "cross-over rule"  Read this first!
You can skip the textbook and the worksheets I handed out in class; the information is covered in the worksheets. If you need extra help, see the following videos by Tyler Dewitt.

I think this subject we can mainly cover in homework, but if you have trouble spots, please let me know, or if you need more practice. I need feedback!!! I will quiz on Monday on ionic/polyatomic  formula writing.

Here's a cool interactive Periodic Table:  http://www.ptable.com/#Compound
It's fun to play around with!  [really!]

No extra homework, unless you need to catch up from last week.  Exploratorium on Wednesday; bring camera-device if you can (phone, etc.) to take pics of exhibits to remember along with the written description, and I'll give tickets for good pictures!  Maybe we'll have a treasure hunt!

O, and keep learning that song!  Danny, can you do the chorus on the  accordion?  That would be so amazing!

Periodic Recap and onto Ions!

CRASH COURSE CHEM: The Periodic Table

Next:
Video #7: The Periodic Table
Scroll down the page.
and watch The Periodic Table (press VoD button)  28 minutes, but you can quit after about 18 minutes, if you wish.

Read ahead: Textbook 3.10 -3.11 + end of chapter  questions for those sections. (page 83)

worksheet: http://academic.pgcc.edu/~bsuitte/chem%201010/Nomenclature_Worksheets%20covers%20all.pdf  Print pages 1-4, and  do  worksheets  #1 & #2!!!

Keep memorizing Periodic table song; making a video soon.
And if you can , read further into Uncle Tungsten.
Thanks, and have a great day

So depending on whether you have studied particle physics before, this stuff is a review or else it is getting your feet wet. There is so much more we could cover, and we will, but for now we are getting used to thinking about the basics of atomic structure and the basic periodic table, and all the vocabulary that goes along.

Very Short but Interesting Videos:
Basic Atomic Structure

Amazing Atoms - What Atoms Are Not Like.

Have you ever seen an atom?

And this will help you with the textbook reading:  Print out the table below before watching the 7 min. video textbook.
  The Periodic Table
Print out this periodic table:
http://www.evanschemistrycorner.com/chempt-2011.pdf
Color in your periodic table in groups as you watch/read:
metals
metalloids
non-metals
Now for Mr. Anderson: A Tour of the Periodic Table (10 min)
Also color in:
alkali metals
alkaline earth metals
halogens
noble gases
transition metals

Reading Textbook: 3.8-3.9, plus section questions on page 82-83  .[If you have trouble with getting to the worksheets, try finding the site and going from there.]

Print this >>>Worksheet:
http://www.evanschemistrycorner.com/Labs/Atomic_Structure/L2-5A_Drawing_Atomic_Diagrams.pdf  The diagrams might look like this (electrons are in energy levels) except you can just write how many electrons in each energy level.  We'll go over it in class if it is too confusing.



Last but not least read another 30+ pages of Uncle Tungsten.   AND...keep memorizing the Song:

Why do chemists make such bad puns? ...

Because all the good ones Argon.

The following homework is due MONDAY, October 7th:

I'm going with this song, even though Daniel Radcliffe's is cooler, and even though y'all voted for that one.  This one's in order and has the symbols and a picture clue as to where you might find the elements in nature or technology.  So start memorizing; I am taking up the challenge of a video response (on your behalf) Seriously... video taping in 2 weeks.

Ten Tough Guys -Learn this list of elements and their names.

Element Symbols
Sb Cu Au Fe Pb Hg K Ag Sn W	Antimony  Copper  Gold  Iron  Lead  Mercury Potassium  Silver  Tin  Tungsten	Sb- From the Greek words 'anti' and 'monos' meaning "opposed to solitude". Cu - From the Latin word 'cyprium', after the island of Cyprus. Au - From the Latin word 'aurum' meaning gold. Fe - From the Latin word 'ferrum'  meaning iron. Pb - From the Latin word 'plumbum' meaning lead .Hg  - From the Greek word 'hydrargyros' meaning 'water' and 'silver'. K - From the Medieval Latin word 'kalium'  meaning potash (pot ashes). Ag - From the Latin word 'argentum' meaning silver. Sn - From the Latin word 'stannum' meaning tin W - From the German word 'Wolfram'. Ancient alchemists called the metal "spuma lupi," the Latin words for  'wolf foam' which was translated to the word "wolframite" in allusion to the objectionable scum or substance formed during the smelting of tin ores containing tungsten.

Reading the Textbook: Chapter 3.4-3.7 + section questions.

As well as the textbook:

Documentary: The Story of Science (55 minutes)

Q: What did the bartender say when oxygen, hydrogen, sulfur, sodium, and phosphorous walked into his bar? 
A: OH SNaP!

Lastly, try to fit in some reading, Uncle Tungsten; sorry that I have not been assigning pages.  My family has had a pretty full month, some of you the same, and I have not wanted to overburden you in these first weeks of school.  It is a bit off the mainstream to assign a reading book for science, but I think there is great value in an integrated approach.  I hope you read at least one "science" book each year for the rest of your life.  A science book that is not a textbook! Just for the pleasure of it.
