Review...

Homework this week is to spend  three  45-minute periods  reviewing your chemistry textbook, chapters 1-17. (To be sure you understand me, that is, three periods of 45 minutes each.)  Vocabulary and summary pages, notes and worksheets, comic book guide, blog and maybe a few videos (but not too much time with videos.)  MAINLY TEXTBOOK.

Monday I will give out  a review exam.  I will also ask for a self-evaluation, reflection on your study habits, learning strengths and weaknesses, etc. How would you grade yourself?

I think I will skip homework on Redox reactions; so...just the review.

Main Idea for Oxidation-Reduction reactions: Follow the electrons--it makes all the difference.

Starting the Review:


If you think you might like to take the placement test, sooner would be better than later; results are good for 3 years, although it may be different for chemistry, because to do 1A you must also petition.  You need to be a  JC student.


  • Read Chapters 1 & 2 in the Cartoon Guide to Chemistry. It is not necessary to color, but you can if you want to.



  • Le Chatelier Experiment:  Fill in as much of the Question section as possible, since you won't have much/any homework time this weekend.



  • Collect and organize all worksheets and notes from chapter 17, Equilibrium.




  • I have forgotten to collect the corrected tests from chapters 13-15.  Could you complete those and bring by Monday.  thanks.

Don't worry; be happy!

This video is actually homework for the midsci class, but you might enjoy it too...
Overview of the next chapter: Equilibrium

Videos: IsaacsTEACH unit 11- Equilibrium  This is the playlist, includes 8 videos for the chapter, but 1-5 to start.  Take great notes, and keep them.
Reading: pages 527-537 ( Chapter 17 sections 1-5)  (in the car, at the beach???) UNDERLINE important bits to remember,



Also read through our experiment pages before Thursday, at least experiment A & B.

Don't you dare wait till Sunday!

ew.

Take a few moments to consider our "experiment" with the cabbage juice indicator and the household products;  we mostly played around, somewhat haphazardly, to find relative pH for each substance and then placed them on a pH scale.  Very pretty.  But we should ask ourselves a few questions, such as, How did concentration affect the pH? How could we have made this a better experiment? What did we really learn? Leave a comment or pose a question below. (yes, everyone.)

Review your notes so far from this chapter's videos (which should now be in a new section of your chemistry binder, right?)  and page through  textbook sections 16.1-4, making sure you know the vocabulary and summary.  Then practice calculating concentrations/pH conversions with the blue-letter Problems 30-36 at the end of the chapter on page 533. Remember the blue-letter problems have answers in the back of the book.

New reading: 16.5 through  16.8.  Worksheet  to accompany 16.7 Acid-Base Titration  answers to follow , but watch Isaac TEACH first:

Experience the Power of the [H+]!


STUDY HINT: When you study chemistry section by section in multiple homework assignments, spend a few minutes to review the chapter from the beginning before you go on to the next section:  the vocabulary, the summarizing points, and the math bits, in particular.  You will find that as you do so, what you once thought difficult will become more and more familiar, maybe even easy; you will understand the following sections more thoroughly, and you will automatically be prepared for the test.

Two worksheets that review yesterday's lesson:
http://www.csun.edu/~JTE35633/worksheets/Chemistry/19-1EquationsAcidBases.pdf
16.1 answers
http://www.csun.edu/~JTE35633/worksheets/Chemistry/19-2ConjugatePairs.pdf
16.2 answers
You don't need to do all the problems, just enough so you know you've "got it."  Also, print out this one:
http://www.csun.edu/~JTE35633/worksheets/Chemistry/19-3pH.pdf 
and the pH worksheet answers here.

To review or substitute for section 16.3, watch and take notes:https://www.youtube.com/watch?v=k6gpQy6H490 13 minutes MUST TAKE NOTES!  After this it will be easier to do the math problems from 16.3.  Do some of those.

Also watch: Take NOTES!



On to pH; more from Amy---> 18 minutes Helps with math and calculators.
https://www.youtube.com/watch?v=BM0SnHf97mg  
ABSOLUTELY you MUST follow along with your pencil and calculator!!!
This will cover the material from 16.4, now you should be able to do the worksheet printed out above. (19.3 pH) You may need to reference your textbook as well.


STUDY HINT: When you study chemistry section by section in multiple homework assignments, spend a few minutes to review the chapter from the beginning before you go on to the next section:  the vocabulary, the summarizing points, and the math bits, in particular.  You will find that as you do so, what you once thought difficult will become more and more familiar, maybe even easy; you will understand the next chapter more thoroughly, and you will automatically be prepared for the test.

Thursday is Instrument Day!

And we will be sharing our instruments with both our class and the youngers! so rehearse your demonstration--I'm sure your mom would love to be a practice audience. :)  Just 2 minutes maximum; demonstrate your instrument and explain how it works. 

Textbook Reading, Chapter 12 (Sound) sections 2 and 3: Properties of Sound/ Music.  Worksheets which correspond are pages 18,26,27,30,and 31.  Review your previously done worksheets.

That should be plenty!  Hopefully you will do section 2 on Tuesday and section 3 on Wednesday, in order to retain more of what you've learned.

If you are still looking for ideas for a musical instrument, check the previous blog.

Try Thinking in Pictures!

New Chapter! and we must dive in, SO DO THIS FRIDAY!  Acids and Bases, Chapter 16, sections 1-3 --you will have to do the end of chapter questions, section by section, and do them all so that you are PROFICIENT before you go to the next section.  HOWEVER, watch the 3 videos first (about 20 minutes total.)

I haven't watched them yet but for video explanations, let's try IsaacTEACH:  TAKE NOTES

Here is the full chapter playlist: watch the first 3 videos.
http://www.youtube.com/playlist?list=PL9FEB76376FCD1A06

I am now going to do the homework myself, so I will check back in if I need to alter anything.

I did most of it -- very time-consuming. answers here - 7 pages! 

This last video, after you have watched the "auto-ionization of water" video or textbook section, demonstrates how much easier it is to understand chemistry visually, rather than in words.

Tuesday, April 29, 2014

When I make the test for Thursday, I will focus on vocabulary and content that I think are most important, and so when you study, you should try to think like me.  The comic book guide is a good start, as well as the worksheets and the videos and the graphs  and of course the experiments and even the blogs. I like giving short-answer essay questions, because that tells me most clearly what you did and did not understand, and perhaps what misconceptions remain.  So study hard, give it your best shot, and enjoy the struggle...


You'all had a blank look yesterday when I mentioned colligative properties, so here in a nutshell...
Read and do just enough of the worksheet problems to "get it".

The best way to learn is to TEACH!

Homework:
  1. Put your notebook in order/review for the test.  Gather notes/worksheets/experiments from chapters 13, 14, and 15 ( gas laws, intermolecular forces, liquids and solids, solutions); it should have its own section and should be put in a sensible order. Review vocabulary and main concepts and math work. Also review chapters 6-7 from the comic book guide; this should all be coming together now, hopefully.  Be able to read/interpret the graphs. Test on Thursday.
  2. Worksheet from class:  Types of Solids, look in your textbooks chapter 14.6 and 14.7. Also Mr. Anderson...                                                                                                                                    23 - Ionic Solids
    24 - Metallic Solids
    25 - Covalent Network Solids
    26 - Molecular Solids
  3. Math worksheets from class: Molarity and Dilutions (answer sheet to follow...)
  4. And prepare your demos! to be done on Monday!  Let me know what you need TODAY, because I might not have it!  I'm really looking forward to these; the last time we did this, it was amazingly productive -- The best way to learn is to TEACH!

A preview of this chapter, Solutions:

This week's topic, Solutions, is well covered by these three teaching videos.  Follow along with the handout I gave you in class. (Jacquiline, you can print out from the site).  Lots of pages, but most of them go pretty fast.  Each video is about 25 minutes, so break it up.

Videos are found here:
http://www.gpb.org/chemistry-physics/chemistry/1001#
http://www.gpb.org/chemistry-physics/chemistry/1002
http://www.gpb.org/chemistry-physics/chemistry/1003

These lessons covers sections 15.1-15.3 and 15.10 in our textbooks. (The rest of the chapter is the maths.)
Also chapter 7 in the comic book guide, pages 129-140.

Begin to collect your notes for chapters 13-15, we will have an exam, emphasizing vocabulary, major concepts and a little math (gas laws, molarity)
This Thursday we will pick out demonstrations to do for Monday's class on topics covered recently- gases, phase changes, pressure, solutions.  Next Thursday will be the test. (material covered by blogs since March 20th).

TGIGF!

Thank God! It's Good Friday!

and no homework, unless you are catching up.   

You are all invited to Open Door's Good Friday service at Pioneer Park at noon.  David Harmon is speaking, and Jesse and Jadon are leading worship at the Gazebo.

TAKE NOTES!

 
For all these videos, TAKE NOTES!
But the next video is just interesting, so notes is optional. [vocabulary to remember: hydrophobic "water-fearing", hydrophilic "water-loving"]
 

Having watched these videos, reinforce your learning by reading the rest of chapter 14, sections 4-7, as well as re-reading chapter 6 of the comic book guide to chemistry.  Highlight major points as you go.

Spend some time thinking about Monday's experiment, and reform your answers to the questions to reflect your increased understanding of evaporation and vapor pressure.  I would like you to turn in both experiment pages (cooling wax/boiling water + evaporation)  

If you missed class on Monday, here are the experiment pages: 

Friday, April 11, 2014



Homework for today is to finish what is left from Monday's homework, and to read  sections 14.4 and 14.5;  take notes on the learning objectives and vocabulary of each section (written under the title), and answer focus questions.

Also read from your comic book guide to chemistry - chapter 6, States of Matter.
Looking ahead: I want each of you to prepare individual solid/liquid/gas/phase change demonstration/experiments, similar to what we did earlier in the year with chemical reactions, to share with the class.  I will have some to choose from on Monday, or you can find your own online or at the library or whatever. Short and "simple", with clear explanations.

chemistry sucks...

we're talking straws here, and air pressure->>> and how our studies of the properties of gases, liquids and solids relates to the real world.



Actual paper homework: Finish the experiment worksheets from class, as well as the handout worksheets. --It's probably not as much as you think, even though it is a lot of pages.
Here is Avery's data, and my own from home, on the Heating Water experiment: https://drive.google.com/file/d/0B07s3-bcUr7tZFlNYnNyajRMa0U/edit?usp=sharing which you will need to graph, one or the other, or both. [This page is a table of the HEATING WATER experiment, but it is labeled as the cooling wax--please adjust.]

Textbook reading: Chapter 14, sections 1-3 with Focus Questions {Notice the OBJECTIVES at the beginning of each section, and be sure to take notes on those concepts, and draw pictures to illustrate!} This saves lots of time!
Also, End of Chapter Problems 21-23.

Videos to accompany 14.1 -->>>

Videos to accompany 14.2 -->>>

Video to accompany 14.3 -->>>  -->>>
Remember to do the Focus questions  (pg 449) and the End-of-Chapter Problems 21-23!

ABC's of Gas

Avogadro, Boyle, and Charles, combined into an Ideal equation.


Homework is to complete the two worksheets handed out in class. Answers
Missing worksheet?
http://www.csun.edu/~jte35633/worksheets/Chemistry/14-3CombinedGasLaw.pdf
http://www.csun.edu/~jte35633/worksheets/Chemistry/14-4IdealGasLaw.pdf

And here is some reading on gases: http://www.chemistryland.com/CHM130S/12-Gases/Gases.htm

STUDYING FOR THURSDAY'S TEST:  I've decided to limit the test to the material in chapters 11 -12, so review the Key Terms and Summary at the end of each chapter,  and especially the worksheets. Any questions?   If you would rather delay the previous homework till spring break in order to study for the test, that's OK with me. I will not be assigning additional homework for spring break.

Lasleys, here is a simulation that can substitute for the lab: http://phet.colorado.edu/en/simulation/molecule-shapes Notice how you can rotate the images.    Notice the function of the lone pair of electrons, how their presence contributes to the shape of the molecules.


Brina, Anthony & Abel - You can watch the you-tube versions of what we did in class; take notes/diagram the experiments and try to explain the phenomena.

And now some simulations...http://phet.colorado.edu/en/simulation/gas-properties


The rest is all math, I'm afraid.  Reading textbook 13.1-13.4, and do these worksheets as you go along. You may not need to follow the book too deeply, and you can substitute any video tutor on the subject.


  1. Pressure Conversions  problems 1-5 write out the definitions of units [mmHg, torr, atmosphere, Pa] 
  2. Manometers problems 1-4
  3. Gas Laws Intro  All
  4. Boyle's Law problems 1-4
  5. Charles' Law problems 1-5
  6.  If you've received the Cartoon Guide to Chemistry, there are several pages about gases, pages 110-114
ANSWERS

Finally, if your cup is running over with homework, and your brain starts to get useless anyway, it would be OK to put off finishing, especially since there is a test on Thursday and you will want to go over Chapter 10-12.   That will mean more homework over break, however.  Definitely do some of it, or there will be no point to Monday's class.


Tuesday, March 18, 2014

[Lasleys, sorry you're sick, you can do the lab from class at home - it is in the textbook on page 393]

 Take notes!


Wrapping Up Chapter 12: Understanding Molecular Bonds:
- review Key Words by writing definitions or "pictographs" for each word on the list (page 394)
-read Summary to make sure you "get" the major concepts for this chapter
-answer the Critical Thinking questions 53-60 at the chapter's end.
-do this worksheet: http://www.csun.edu/~jte35633/worksheets/Chemistry/6-3AtomicRadius.pdf
I would like you to turn in a packet of your work from this chapter on Thursday - please organize all your notes, worksheets and Q/A to turn in on Thursday.  Check past homework blogs to see if you missed any homework. Put everything in a cheapy folder.  Copies are acceptable.

Did you ORDER a copy of the Cartoon Guide to Chemistry???????

PART ONE of the homework:  World of Chemistry 8. Chemical Bonds   28 minutes 

PART TWO: watch this short video and finish up the worksheet from class, and then start reading chapter 12, sections 1-3 answering all the end-of-chapter questions and problems for those sections (page 394-395). Take notes as you read, including Key Terms and copy the illustrations.  I will probably add another video or two tomorrow.  thanks.


Take notes as you watch...Always take notes!

Also, order a copy of The Cartoon Guide to Chemistry from Amazon, or elsewhere. http://www.amazon.com/Cartoon-Guide-Chemistry-Larry-Gonick/dp/0060936770/ref=sr_1_1?ie=UTF8&qid=1394556301&sr=8-1&keywords=cartoon+guide+to+chemistryReturn to product information

Electron Gofigurations

              

1. Textbook sections 11.9-11.11; also review the Key Terms and Summary on page 354. Videos are another option for sections 9-10; see below. (But do read section 11).


2. Worksheets handed out in class (3) The best way to understand is to practice the paradigm!  Also, here is site to check the difficult ones; and yes, there are exceptions! http://en.wikipedia.org/wiki/Periodic_table_(electron_configurations) Some of you will really hate this stuff, and others will find it oddly pleasant...I am one of the latter. Go figure.

3. "Questions for Analysis" from lab.

If the book is confusing and you would rather watch a video, here is a sequence that should be OK:
(If you find something better, let us know!)

So this teacher makes mistakes too!

A periodic table of orbitals

video:  The World of Chemistry: The Atom  click the VOD button by #6-The Atom.  28 minutes.  A review of the atom that summarizes this week's lesson aims, particularly in the last 10 minutes. If you are very comfortable with the whole atomic theory stuff, just watch the last 10 minutes and go on to the more advanced material from  The Mechanical Universe: Particles and Waves click the VOD button for #50.  This is extra understanding for those of you who wish to go deeper.  28 minutes. and fascinating (to me). If you are intimidated by the  math, just pretend that the equations are doing complicated dance moves.  If this year has been your first introduction to atomic theory, just watch the first video in its entirety and skip the second.

Textbook reading: 11.7-11.8 which may make our whirlwind tissue paper art project have a little more meaning to us.  Answer end of chapter questions for each section.

And here is a worksheet that will help you see the patterns: Where are the electrons?

Lastly, a site to peruse: The Orbitron  Don't read it, just click on the various sub-levels to see the increasing complexity of the higher energy levels.

Thank you for your very excellent work on the lab reports, and for the fantastic level of cooperative learning demonstrated in class.  You make me feel like a real teacher.
