3 January 2011 • Have your notebook open when the timer reads “4:00” • Please copy the objective and answer the Do Now Question. • Objective: SWBAT review classroom expectations and writing and balancing chemical equations. • Do now: For each one: Ionic or covalent? a) AlCl3 b) CCl4 c) Cu(OH)2
Welcome Back! • Happy New Year!!
Agenda • Do now • Review of Expectations • Review of Writing and Balancing Equations • Writing and Balancing Equations Practice Problems. • Exit Ticket Homework: Finish Writing and Balancing Equations Worksheet: Tues.
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 Otardies 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.
On your worksheet • Find the mistake in the formula equation. Circle the mistake and explain WHY it is a mistake. • Rewrite the balanced equation correctly. • Then, complete the related problem below.
Homework • Complete the writing/balancing equations worksheet. • Due tomorrow
Exit Ticket (4 min.) • Complete this problem ON YOUR OWN so I can see how YOU are doing on this. • Full credit = you complete it on your own.
