LAST WEEK OF THE TRIMESTER!

We're in the home stretch... aren't you all excited?!?

I want to thank all of you for your patience with me while I was sick last week. I'm feeling much better and appreciate all your well-wishes!

BIG ANNOUNCEMENT: Apparently I put faulty directions on your Periodic Table quiz! Were you all confused? On MONDAY I will GIVE YOU BACK YOUR QUIZZES with new directions: to just give me the abbreviation of each of the elements at the bottom of the quiz. I have not graded them because I want to give you all another chance to answer the bottom part of the quiz.

ANOTHER BIG ANNOUNCEMENT: This week, I will not take up any homework. The only paper you'll have to turn in is our lab. I'll assign it as a way to study for this week's test-- not as an item to be graded. HOORAY!

THIS WEEK'S SCHEDULE: ****LAB MOVED TO WEDNESDAY BECAUSE OF LAB SPACE CONFLICT***

MONDAY 15 more minutes of quiz time; discuss chapter 5 section 3. Key words: ATOMIC RADIUS, VALENCE ELECTRONS, IONIZATION ENERGY, ELECTRONEGATIVITY.
HOMEWORK: read the lab for tomorrow!
TUESDAY give back/go over tests, homework, etc...
WEDNESDAY LAB: halide salts
THURSDAY review chapter 5 HOMEWORK: turn in Halide Salts Lab.
FRIDAY test on chapter 5

Friday's test will ask a lot about the groups of the periodic table and the reactivity of different electron configurations.

See you Monday!

THIS WEEK'S SCHEDULE

Here's our Dude of the Week: DMITRI MENDELEEV.

He's the guy who, finally and at last, got together everything known about different elements and organized a table called the Periodic Table. We'll talk a lot about him.

MONDAY: begin chapter 5: Mendeleev and the Periodic Table
HOMEWORK: read ch 5 section 1 for READING QUIZ
TUESDAY: READING QUIZ on ch 5 sx 1: finish sx 1, move into sx 2
HOMEWORK: worksheet ch 5 sx 1; read section 2
WEDNESDAY: Ch 5 sx 2: periodic table vocab, names, trends.
HOMEWORK: choose 2 periodic GROUPS and write a paragraph about each group's properties. Choices: alkali metals, alkali earth metals, halogens, noble gases, transition elements, metalloids, hydrogen (in a group by itself!)
THURSDAY: Determining an element's group from its electron configuration.
HOMEWORK: get ready for a PERIODIC TABLE QUIZ!
FRIDAY: periodic table quiz**-- see below.
HOMEWORK: read section 3 for MONDAY.

**Guys, it is time to memorize some facts from the periodic table. On Friday, you'll have a QUIZ ON THE ELEMENTS up to number 86. I need for you to know the abbreviation for each element (IOW, what is P? What is Pb? What is W?), and, if applicable, the name of the group each element belongs to (halides, alkali metals, etc...). THE PERIODIC TABLE WILL STAY UP FOR THIS QUIZ, but you need to know all the names and vocab!

Next MONDAY AND TUESDAY, we'll do a lab on the reactivity of halides and alkali metals. Then move on to Section 3.
here's a Happy Halloween video for everyone!

THIS WEEK'S SCHEDULE

Wow, this chapter is hard! Between that and losing students for sporting events, we have to move the test to THURSDAY OCTOBER 27TH.

So here's our week:
MONDAY-- wavelength/frequency problems: Gizmo on electron shells and how they fill
HW: worksheet on ch 4 sx 2 (if not done already), wavelength/frequency problems
TUESDAY-- more of the electron shell Gizmo
HW: electron shell problems
WEDNESDAY: Review ch 4
THURSDAY: TEST CHAPTER 4
FRIDAY: start chapter 5-- the periodic table


The test will cover chapter 4 sections 1, 2, and 3. Particularly you'll need to know:
* the Bohr model of the Hydrogen Atom
* how and why atome emit photons of light
* the dual wave/particle theory of proton behavior, and what this has to do with photon emission and the various electron shells
* how to convert wavelength into frequency and vice-versa (we'll work problems on this Monday or Tuesday).
* the basic types and shapes of electron orbitals
* Quantum numbers of the atom-- including energy level, angular, spin, and magnetic numbers
* how electrons fill the electron shells-- in what order, how many per subshell, how many orbitals per shell, etc...
* proper electron shell notation, including Noble Gas Notation.

I will be at tutorial on TUESDAY AND WEDNESDAY MORNINGS starting at about 7:50. If you've missed class recently because of sports, you'll NEED to come to one with your QUESTIONS READY!

--And now, some links for you!

1. Guess what? YOU CAN PLAY WITH THESE GIZMOS AT HOME!
Just go to:

Then look to the upper right corner and click on "enroll in a class".
You'll have to sign up for a (free!) account with explorelearning.
When it asks you the class code, enter R8DRANFAXP

2. Here's a power point on how to work the wavelength and frequency problems:

THIS WEEK'S SCHEDULE

On wednesday or thursday, we'll be turning Physics into chemistry by learning about ELECTRON ORBITALS. They're crazy, so fasten your seat belts... but they're cool and they give us some hints as to why we saw what we did in our flame test lab last week.

A couple of videos I'll use:

For Chapter 4, section 2:


for Chapter 4, Section 3:


TUESDAY-- homework review for chapter 4, section 1\
-- check out the results of our egg lab!
-- READ SECTION 2
--- QUIZ ON SECTION 1 TOMORROW!
WEDNESDAY-- QUIZ SX 1.
-- QUICK LABS: wave interference, Heisenberg Uncertainty Principle.
-- video above on ch 4 sx 2; ppts?
--HW: ch 4, sx 2 worksheet
THURSDAY -- go over sx 2 homework
-- begin section 3: orbitals and their shapes VIDEO
-- hw: READ CH 4, SX 3
FRIDAY -- More on orbitals and their shapes
--orbitals and their shapes WORKBOOK SHEET
-- draw through periods 1, 2, 3

You'll have a TEST ON CHAPTER 4 NEXT TUESDAY, OCTOBER 25TH!!!

THIS WEEK'S SCHEDULE

this week we're continuing our history lesson with Neils Bohr and his theory of how electrons behave. He was the guy who discovered that it's the ELECTRONS that determine how an element will act and react.


Here's a LINK TO THE CHAPTER 4 POWER POINT.

HW: ch 4 sx 1 worksheet due TOMORROW

TUESDAY-- lab: flame tests and photon absorption/emission

THIS WEEK'S SCHEDULE

Sorry not to post this yesterday, y'all! Was busy writing your comments.
Today you all took your chapter 2 "big quiz." I'm betting everybody did well. So from here:

Tuesday: chap 3 section 1-- atomic theory. HW: ch 3 sx 1 worksheet: read ch 1 sx 2.
Wednesday-- What is an atom and how do we know?HW: ch 3 sx 2 wksht
Thursday-- More on What is an Atom? HW: read lab
Friday-- LAB: law of conservation of mass

the next week we'll learn how to talk about weights of atoms. Expect a test at the end of the week.

NOW: Check this out. Click Here! scroll all the way across to see how big (or tiny) an atom is.

THIS WEEK'S SCHEDULE

Get ready, because we will TAKE A TEST ON CHAPTER 2 ON FRIDAY! It's a short chapter.

Also... I'm really sorry guys, but we have to defer the "Taste Test" portion of the popcorn lab to Tuesday. Seems that my schedule won't allow me to have popped-up corn for you on Monday. So we'll pop-but-not-eat Monday and eat/discuss data on Tuesday.

See the calendar to the right. Highlights:

MON- Popcorn Lab-- the not-eating portion. Turn in Ch 2 sxn 1 HW if not already in.
TUE-- Popcorn Lab-- the taste test. Discuss data for popcorn lab; HW: read ch 2 sxn 3.
WED-- Scientific notation and sig figs. HW: ch 2 sx 3 worksheet
THUR-- finish up chapter 2
FRI-- chapter 2 test

Sunday, September 4, 2011

MORE ON CHEMICAL AND PHYSICAL CHANGES

Here's my hero, Paul Anderson, explaining chemical and physical changes. We'll watch him on Tuesday, then do some chemical and physical changes of our own in the lab.

Friday, September 2, 2011

NEXT WEEK'S PROJECT:

Be thinking about which element you'd like to do for next week's poster project, which will start Tuesday and be due Friday. Have at least three you'd like to do, because no two people can have the same one!

Have a great weekend!
