Good luck on the exams boys

If you go through my site, you'll find sample exams that are pretty good. there's multiple choice and answers. if you have a question, i can help you. if you want tutoring...no. i don't want to do that... AHAHAHAHAHAHAH kay for 1000 baht an hour and 1500 for two hours... aHAHAHAH now you don't want to do that. if you have a group of kids, 2 people 600 baht each for an hour, 800 for two hours :D 3 -- 400 baht an hour/ 700 for two. basically, more people makes it a bit harder and easier for me so more than 3, say 4 is max-- 4 people 300 an hour/ 600 for two hours. i'll bring worksheets, powerpoints, problems etc. AHAHAH you feel the love

how's it going out there

So how's it going out there? do you need anything? i can post some old questions

Mr. Gary has been recruited to a new job

I was contacted about a new job and interviewed for it and got it. The job offers more money, less work time, and a lot of incredible opportunities for my family--my wife and daughter. Therefore it is with great sadness that I have submitted my resignation to Assumption College and will be leaving there July 28, 2011.

I truly enjoyed teaching the Men of AC and look forward to seeing your further growth and development in the future. Fight on!

YOUR GRADE

it will be a composite score of your participation, test/quizzes, and hw/notebook.

everyone is getting 7 out of 10 minimum on participation--i don't see any lower scores.
take that score multiply by .30

test/quiz--add your scores and divide by the total--if we had 3 quizzes that is 75 points. so say you got 85 out 145 plus 60/75 take that score 145/220 multiply by .40

hw/notebook everyone is doing well so that score will be at this point ep 4 has about 5 homeworks 25 points each, 2 labs 50 pts each, and notes 100 points checked bi-weekly so that's about 400 pts. your total would be 575--multiply that by .3

add those scores up and that's what you're doing going into the midterm--i plan on posting grades after this weekend--sorry for the delay but i've been sick and my daughter also.

midterms grades are a separate grade from your grades in class--they are 20% of your total grade. your final is 20% also so your total grade overall is 60 % class grade, 20% midterm, and 20% final

History and Videos of Debate Club

Historically, the Assumption College Debate Club has done well and continues to be a force in the Debate community of Thailand. Several of our Alumni debate for Chula, Thammasat, Mahidiol, and Assumption University. There is a proud tradition of brotherhood, honor, and respect for our program. Originally started by Mr. Alfred Sole in 2006, his team got to the semifinals at the First Thailand High School National Debate Championships. Mr. Gary was given the lion's share of the club in 2007. In 2008, our number one team of Pongsakorn (EP 6/1), Nuttanan (EP 6/1), and Gear (EP 6/2)--all attending Chula, got to the Semifinals. Nuttanan took 10th Best Speaker of the Tournament. Gear took 3rd Best Speaker. All three were placed in the National Pool for the National Team for the World Championships held in Athens, Greece. Gear competed at that tournament--Thailand took Best Newcomer Country. In 2009, our number one team of Vichitpol (EP 6/2), Thanakorn (EP 6/2), and Suthipat (EP 6/3) lost in the Quarterfinals. Vichitpol is at Thammasat. Thanakorn is very active in debate in Mahidiol. In 2010, our number one team of Teechayut (EP 6/1), Kasidej (EP 4/2), and Tanachai (EP 6/2) lost in the Quaterfinals in a closely contested match. The highlight of that year though was the entry of our team into the International Debate Tournament held in Manila, Phillipines. Chaya (EP 6/1), Kaside (EP 4/2), and Tanachai (EP 6/2) battled through 7 preliminary rounds and finished 3-4 facing international competition. This year, the team has just finished the Sarass Ektra World School Championships where our number one team of Teechayut (EP 6/1), Tanachai (EP 6/2), Sappay (EP 6/1), Thanakorn (EP 6/1), and Chanwit (EP 6/1) lost in the Quarterfinals to the eventual champions. Last month happily, our members won the National Team Debate Camp Tournament held by Patumwan Demonstration School. Our number one team comprised of Napat (EP 5/1) dominated the tournament going 6-0. Prakasit (EP 5/2) team lost in the Semifinals while Kasidej (EP 5/2) lost in the prelims. Our big events this year is the World School Debating Championships held in Edinburgh, Scotland on August 16-26, 2011 where Mr. Gary will travel as the National Team Adjudicator and compete. EU-Thailand will be August 27-30, 2011 at Mahidiol.


The try-outs for the debate teams going to the European Union Thailand National Championships in September start this week and will run until end of July. Practices are held on Mondays--Activity period 7 in EP 5/2, Tuesdays afterschool from 4-6, and Wednesday afterschool from 4-6. We welcome all the newcomers to the Debate Society. Currently we have 29 members. President of our club is Kasidej of EP 5/2, Vice-Presidentis Napat (Pan) of EP 5/1, and Secretary-Public Relations is Patipol of EP 5/2. This week's practice resolution on Tuesday was This House would legalize euthanasia. Wednesday the motion was This House believes that nuclear energy is better than alternative energy. There will be a National Team practice on Friday from 2-8 p.m. at Patumwan Demonstration School see Mr. Gary about accompanying him. The club is very excited about the implementation of their new ranking system with four levels; alpha, beta, gamma, and omega. Currently, the number one rated debater is Kasidej with Pan a close second in the Omega category. Prakasit of EP 5/2, Pathraphong of EP 6/2, Tayakorn of EP 5/2, Man of EP 5/2, Cristayos of EP 5/1, Schwitt of EP 5/2, and Patipol of EP 5/2 rank in the Gamma category. In the Beta grouping, we have Gunthorn of EP 3/4, Withawin of EP 5/2, and Tong of EP 5/2. The rest of the club has been placed in the Alpha Category with Got of EP 4/1 in the lead. Points are given for attending practice (1), being on the winning team (3), being on the losing team (1), Best Speaker (1), judging and chosing the winning team (2), judging and choosing the losing team (1), and exceptional performance (1). Mr. Gary determines when the skill set mandates a move to the next level. The starting teams for EU-Thailand will be chosen from the highest ranking debaters.

ESSAY

30. ANS:
John Dalton used experimental methods to hypothesize that atoms of the same element are identical, and that they differ from atoms of other elements. Dalton also noted that atoms of different elements can form compounds in which the elements combine in whole-number ratios. He noted that individual atoms are not transformed into different atoms as a result of a chemical reaction. What Dalton did not contribute was the fact that individual atoms are divisible into subatomic particles, which came from the discovery of the electron and the atomic nucleus by Thomson and Rutherford, respectively.

DIF: L3 REF: p. 101, p. 102 OBJ: 4.1.1, 4.1.2

31. ANS:
Rutherford’s gold-foil experiment led to this hypothesis. Alpha particles were observed to mostly pass through a gold foil, which suggests that the volume of individual gold atoms consists mainly of empty space. The observation that some alpha particles were scattered at large angles led to the suggestion that the gold atom has a central core, or nucleus, composed of a concentrated mass capable of deflecting the alpha particles.

Welcome to the World of Chemistry
The Language of Chemistry
CHEMICAL _____________ -
pure substances that cannot be decomposed by ordinary means to other substances.
The Language of Chemistry
The elements, their names, and symbols are given on the PERIODIC TABLE
How many elements are there?
The Periodic Table
Dmitri Mendeleev (1834 - 1907)
Glenn Seaborg (1912-1999)
Discovered 8 new elements.
Only living person for whom an element was named.
Branches of Chemistry
Many major areas of study for specialization
Several career opportunities
Also used in many other jobs

1. Organic Chemistry
Organic is the study of matter that contains carbon
Organic chemists study the structure, function, synthesis, and identity of carbon compounds
Useful in petroleum industry, pharmaceuticals, polymers
2. Inorganic Chemistry
Inorganic is the study of matter that does NOT contain carbon
Inorganic chemists study the structure, function, synthesis, and identity of non-carbon compounds
Polymers, Metallurgy
3. Biochemistry
Biochemistry is the study of chemistry in living things
Cross between biology and chemistry
Pharmaceuticals and genetics
4. Physical Chemistry
Physical chemistry is the physics of chemistry… the forces of matter
Much of p-chem is computational
Develop theoretical ideas for new compounds
5. Analytical Chemistry
Analytical chemistry is the study of high precision measurement
Find composition and identity of chemicals
Forensics, quality control, medical tests
Types of Observations and Measurements
We make QUALITATIVE observations of reactions — changes in color and physical state.
We also make QUANTITATIVE MEASUREMENTS, which involve numbers.
Use SI units — based on the metric system
SI measurement
Le Système international d'unités
The only countries that have not officially adopted SI are Liberia (in western Africa) and Myanmar (a.k.a. Burma, in SE Asia), but now these are reportedly using metric regularly
Metrication is a process that does not happen all at once, but is rather a process that happens over time.
Among countries with non-metric usage, the U.S. is the only country significantly holding out. The U.S. officially adopted SI in 1866.

Standards of Measurement
When we measure, we use a measuring tool to compare some dimension of an object to a standard.

What is Scientific Notation?
Scientific notation is a way of expressing really big numbers or really small numbers.
For very large and very small numbers, scientific notation is more concise.


Scientific notation consists of two parts:
A number between 1 and 10

A power of 10
N x 10x

To change standard form to scientific notation…
Place the decimal point so that there is one non-zero digit to the left of the decimal point.
Count the number of decimal places the decimal point has “moved” from the original number. This will be the exponent on the 10.
If the original number was less than 1, then the exponent is negative. If the original number was greater than 1, then the exponent is positive.

Examples
Given: 289,800,000
Use: 2.898 (moved 8 places)
Answer: 2.898 x 108

Given: 0.000567
Use: 5.67 (moved 4 places)
Answer: 5.67 x 10-4

To change scientific notation to standard form…
Simply move the decimal point to the right for positive exponent 10.
Move the decimal point to the left for negative exponent 10.

(Use zeros to fill in places.)
Example
Given: 5.093 x 106
Answer: 5,093,000 (moved 6 places to the right)

Given: 1.976 x 10-4
Answer: 0.0001976 (moved 4 places to the left)

Learning Check
Express these numbers in Scientific Notation:

Stating a Measurement
In every measurement there is a
Number followed by a
Unit from a measuring device
The number should also be as precise as the measurement!
UNITS OF MEASUREMENT
Use SI units — based on the metric system
Length
Mass
Volume
Time
Temperature
Mass vs. Weight
Mass: Amount of Matter (grams, measured with a BALANCE)
Weight: Force exerted by the mass, only present with gravity (pounds, measured with a SCALE)

Conversion Factors

Fractions in which the numerator and denominator are EQUAL quantities expressed in different units

Example: 1 in. = 2.54 cm

Factors: 1 in. and 2.54 cm
2.54 cm 1 in.




Learning Check
Write conversion factors that relate each of the following pairs of units:
1. Liters and mL

2. Hours and minutes

3. Meters and kilometers


How many minutes are in 2.5 hours?

Conversion factor

2.5 hr x 60 min = 150 min
1 hr

cancel





Steps to Problem Solving
Write down the given amount. Don’t forget the units!
Multiply by a fraction.
Use the fraction as a conversion factor. Determine if the top or the bottom should be the same unit as the given so that it will cancel.
Put a unit on the opposite side that will be the new unit. If you don’t know a conversion between those units directly, use one that you do know that is a step toward the one you want at the end.
Insert the numbers on the conversion so that the top and the bottom amounts are EQUAL, but in different units.
Multiply and divide the units (Cancel).
If the units are not the ones you want for your answer, make more conversions until you reach that point.
Multiply and divide the numbers. Don’t forget “Please Excuse My Dear Aunt Sally”! (order of operations)

Sample Problem
You have $7.25 in your pocket in quarters. How many quarters do you have?

Temperature Scales
Calculations Using Temperature
Generally require temp’s in kelvins
T (K) = t (˚C) + 273.15
Body temp = 37 ˚C + 273 = 310 K
Liquid nitrogen = -196 ˚C + 273 = 77 K
Fahrenheit Formula – Honors Only
180°F = 9°F = 1.8°F 100°C 5°C 1°C

Zero point: 0°C = 32°F

°F = 9/5 °C + 32
Celsius Formula – Honors Only
Rearrange to find T°C
°F = 9/5 °C + 32
°F - 32 = 9/5 °C ( +32 - 32)
°F - 32 = 9/5 °C
9/5 9/5
(°F - 32) * 5/9 = °C
Temperature Conversions – Honors Only
A person with hypothermia has a body temperature of 29.1°C. What is the body temperature in °F?
