assignment this Friday
September 11th
Things Due Monday:
September 14th
– HW 1

Attention Getter
• Hand in the air
– My hand goes up I say Heads Up
– You stop talking and look at me so I know your are
ready.
Welcome!
Mr. Koontz
Title your Paper
• First the Last name PRINTED
• Date: 9/9/2015
• Period:
Chemical Systems Finals review
1. I am giving you one of the questions for the
final right now to practice with:
2. Watch the Demonstration and describe with
as much detail as possible using the best
variety of words, visuals, data(sample OK),
calculations on the provided paper.
Did you think about:
• Observations? Did you have detailed quantitative
(number) and qualitative (words, visuals)
observations?
• What forms of matter you saw/changed?
• What kinds of energy transformation/transfer
you saw/experienced
• Think about a systematic way of describing what
happened?
• Do your diagrams show the changes?
• Did you make any inferences?
To your shoulder partner:
• Compare notes discuss the what you saw
To your face partner:
• Switch papers write down one question or
suggestion and sign it with your three intials
of your name- Timothy Andrew Koontz - TAK
Get up and move
• Take your card and your stuff and get up and
move. . Until the music stops
• Find the nearest person that has your color card.
Find out what their favorite food is and be ready
to report out.
• Keep moving mix it up until the music stops
• Find the nearest person you don’t know with a
card with a different color. Find out what their
most memorable moment in a science class has
ever been and be ready to report out.

• Keep moving mix it up until the music stops
• Now notice your card has a number on the
upper left. You may find any seat with your
number and sit there (look at the tables the
numbers are written on there)
• This will be our initial seating chart, so come
back and sit there tomorrow.
On the back of your card. . .
(the side with the lines)
• List 5 things that are unique about you
• Make sure your name is NOT on this side of
the card!!!
What a typical day looks like…
• First few minutes – agenda and “Do
Now”(could be homework or lab quiz)
• Activity of the day: Labs, lectures, groupwork,
practice for assessments, assessments.
• Last few minutes – end class all together
Welcome to Chemistry! Thursday Sept 10, 2015
This is room 393 Mr. Koontz
DO NOW:
Agenda:
• Procedure of the day/Syllabus
Name an energy transformation you saw
topic of the day
yesterday. ( name the initial form of energy
• Introduction to significant figures
and final from of energy)
BE ready to share out. Discuss with your table
Assignments.
everybody be ready to talk about it.
• Scientific Calculator due as an
assignment this Friday September
12th
• Things Due Monday: September
14th
– HW 1
– Dedicated Spiral Notebook for
this class
Objectives:
– Quiz on Sig Fig and rounding
1.
Quantitative Tools for Chemistry:
complete calculations using factor analysis, S.I.
Units, Scientific Notation and demonstrate use of
Significant Figure Rules.
Syllabus topic of the day
• What to bring to class every day
• Get a spiral notebook (200pg is reccomended!)
– due on Monday September 14th.
• Bring a scientific calculator every day! Smart
phones will NOT BE ALLOWED.
– We will be using the calculator everyday starting
tomorrow
– Calculator check will be Due this Friday September
11th as a notebook grade.
• Pencils and pens (pencils are easier to erase)
Notebook
• The Notebook is its own grade category and is worth
15% of your grade
– Low notebook scores correlate with low assessments in
class so DO YOUR HOMEWORK!!!!!!
• The notebook grade will have:
– Classwork: practice in class could be finished at home.
– Homework: practice specifically completed at home.
• Your first homework is due Monday September 14th
Numbers
• At your table as a group discuss and pick the
most famous number you can think of.
• Use a small whiteboard and have person 1b
write down that number as completely as
possible with as much information as you
think needed
Most numbers in science come from
measurements from devices
• Measurements are made with tools and
devices that have limited amounts of precision
• I may weigh these weights in lb:
• A bathroom scale may read 170
• A doctor’s scale may read 171
• A Science lab scale may read 171.4
SIGNIFICANT FIGURES (what about those zeros?)
1. All non-zero digits are significant.
825 has three sig. fig.
2. Zeros located between non-zero digits are significant.
2007 has four sig. fig. (sandwich rule)
3. When a decimal or mixed decimal ends in zero, the zero
is significant.
43.270 has five sig. fig. (right book end rule)
4. When a whole number ends in zero (with no decimal
point), the zero is not significant.
400 has one sig. fig. (no decimal rule)
5. When a whole number ends in zero (with a decimal
point), the zero is significant
450. has three sig. fig. (decimal rule)
Significant Figures Handout
• Often I will give you a notes handout with the
idea that you will want to annotate that
handout with more information while we talk
about it.

Vocab is important in Science
• Significant Figure: each of the digits of a
number that are used to express it to the
required degree of accuracy, starting from the
first nonzero digit.
Sig Fig Rally coach
• Get a piece of paper out one per shoulder
partnership.
• Put both names on
• The period
• The Date 9/10/15
Rally coach work
With your shoulder partner. . . . . . .
Are you an “A” or “B” partner (at your desk)
RallyCoach
• Partners take turns, one solving a problem while
the other coaches.
• Partner A solves the first problem
• Partner B watches and listens, checks, coaches if
necessary, and praises.
• Partner B solves the next problem
• Partner A watches and listens, checks, coaches if
necessary, and praises.
• Partners repeat taking turns solving successive
problems.
