VIDEO: THE MOLE

Students:  here is Paul Anderson's video, as shown in Wednesday's class, explaining the concept of the mole with helpful illustrations:



Student should use this video to complete a worksheet given in class, which is also available online HERE.

NOTES: ELECTRON CONFIGURATION

Students, here is the Power Point for the Unit 2 notes on electron configuration, orbitals, models of the atom, and rules for electrons:



Students should use this along with the previous section of Notes to complete the Study Guide for next Thursday's test (10/18), and along the way make sure that everything in the Study Guide does, in fact, appear in their notes.

HONORS: THE PERIODIC TABLE

HONORS STUDENTS:  Here are the Power Point Notes on the Periodic Table given in 1st period.  

Inside you will find information about the structure of the periodic table, how to read it, how to calculate molar masses, isotopes and ions, ionic and covalent bonds.   This needs to be completed in your Composition Book this week, as we are moving on to other material.



VIDEO: FLAME TEST

If students were absent on Monday, Oct. 21st, they did not get to see the actual lab where we performed a 'flame test' on various ionic compounds.   

Here is a video that shows much the same sort of observations students made on Monday.   Unfortunately, it is not practical to 'make up' this particular lab. Watch the video, students, and compare it with observations that students who attended were able to make in order to understand the material:

"MOLE DAY IS COMING!"

You don't want to miss Wednesday's class.

There will be fire!  explosions!

REGULARS: SATURDAY SCHOOL

Is it an opportunity or a punishment?

That's up to you, students.

Some of the students in my Regular Chemistry classes have received a YELLOW CARD which assigns them to Saturday School, where they will work on a package of remedial work.

Saturday School for Regulars will occur on Sat., Oct. 26th.

It is the responsibility of students to have parents contact the instructor to make an alternative arrangement in the event of a conflict.

VIDEO: COVALENT AND IONIC COMPOUNDS

Both Honors and Regulars are doing activities in October that require them to distinguish between covalent and ionic bonding.  This video from Paul Anderson is a master teacher's original way of teaching how to use a periodic trend (electronegativity) and the octet rule to determine whether a compound is ionic, polar covalent or non-polar covalent.



VIDEO: THE BUNSEN BURNER

VERY IMPORTANT:  On Monday, Oct. 21st, all of Mr. Hatfield's classes (Honors AND Regulars) will be doing an activity that involves gas.  Students are expected to know how to do this safely!

Mr. Hatfield has made a video to demonstrate the correct way to use the Bunsen burner.  Make sure you review this before you come to class on Monday, as we will be using the Bunsen burners in class to perform the 'Flame Test Lab'.


HONORS: STOICHIOMETRY

Honors Students, I am making this Paul Andersen video available through the class blog.   Please watch as many times as you need:


The worksheet based on this video is available online HERE:

VIDEO: "FIREWORKS!"

Students who were in Mr. Hatfield's classes on Thursday, Oct. 16th, watched a PBS video entitled 'Fireworks!'  Students who need to watch it again, or who were not present on Thursday, will find the video embedded below in this post.

The worksheet for this video can be obtained HERE.

Students should pay careful attention to items from Chapter 5 (electron configuration) and Chapter 7 (ionic compounds):

HONORS: THE CONVERSION EXPERIENCE, PART 2



Honors Students:

This is the SECOND part of 'The Conversion Experience', which are the Notes that form the basis of the Study Guide of the same name.


The first part covered the concept of the mole and molar conversion problems, which used fractional setups with cancellations.

This second part adds the concept of the balanced equations used to describe chemical reactions, and combines those equations with molar conversion setups to make real-world measurements of predictions of actual reactions.


Just click 'HERE' or on the graphic above to download the notes!

VIDEO: "THE LIVES OF THE STARS"

;

The following episode of Carl Sagan's Cosmos, 'The Lives of the Stars', forms the basis of a student homework assignment given in class on Friday, September 1st.  

It can be viewed on-line currently HERE.

EXTRA CREDIT, UNIT 2 (REGULARS)

Students:   This message is for students in Mr. Hatfield's Regular Chemistry sections (periods 2-5):

RA 4

RA 5

RA 6

The above assignments are the section assessment questions from Chapters 4, 5 and 6 from your text.  


These assignments are found on 'turnitin.com'.  

Please submit your ORIGINAL responses, which must be in COMPLETE sentences that REFER TO THE ORIGINAL QUESTION.  Each of these assignments can earn you up to 15 points of extra credit---very helpful in this course!

REGULARS: THE PERIODIC TABLE

Students:  Here are the Power Point Notes on the Periodic Table given to my 2nd, 3rd, 4th and 5th-period classes.  Inside you will find information about the structure of the periodic table, how to read it, how to calculate molar masses, isotopes and ions, ionic and covalent bonds.  This is all material that will be on your next Unit Test, on Tuesday, October 8th.


HONORS: THE CONVERSION EXPERIENCE, Part 1

Students:  These are the Power Point Notes for the first part of  'The Conversion Experience', which introduces the mole, conversions to mass (grams), volume (Liters) and particles of substance (atoms or molecules).



The second part of these notes will contain material on chemical reactions and stoichiometry problems,which apply the conversion techniques currently being practiced by students.
