Review of Expectations

Be on time
 You must be in your seat when the bell
rings.
 You must have your notebook open and
homework out when the timer reads
4:00
 3 tardies = IR
 Everyone starts at O tardies today. 
Do the Do Now
Copy the Date
 Copy the Objective
 Answer the Do Now question
 Be ready to explain your answer
 You should have PLENTY of time to
complete this!

Follow directions
Stay in your seat unless you have asked
my permission to do otherwise.
 Think carefully about when is a good time
to use the sharpener/get hand
sanitizer/get a tissue.
 Srsly, we need tissues in here. I’m
working on that!

Hand in your work on time
And be responsible about making up work
you miss when you are absent
 Show me your homework the day you
return.
 Have a friend in all your classes write
down your assignments for you, and
collect handouts.

The next three weeks are so important!!
Late work is due Wednesday, January 19
 Midterm Exam Review starts Jan. 21!
 Finish the quarter strong to build your
grade going into midterms!
 I will hand out progress reports this week
so you know what missing work you have.
 65% is so much better than a O.
 If you have a lot of missing work, see me
to help you prioritize.

Classwork Points
Do you always follow directions and think
you should be rewarded for it?
 Do you need some incentive to stay on
task?

Classwork Points
One classwork point will be awarded at a
random and unannounced time during
each class.
 If you are doing what you should be doing
(doing the Do Now, working silently,
doing a lab with your group, working in
your seat with your partner) you will earn
the point.

Reviewing writing and balancing equations
Why?
 On the Copper Cycle Lab, many people had a
seriously difficult time with this.
 Writing and balancing equations is central to
success in chemistry and will be important
for the rest of the year!

Example 1

Solid copper reacts with a solution of
silver nitrate to produce solid silver and a
solution of copper (II) nitrate.
Example 2

Solutions of sodium hydroxide and
calcium bromide react to produce a
solution of sodium bromide and solid
calcium hydroxide.
