• We will bring back equilibrium today and look into how collision frequency and equilibrium are related.  We will also look at how the position of equilibrium can be predicted and/or shifted using Le Chatelier's Principle.

• Homework is to read the lab instructions for the Le Chatelier's Equilibrium Lab (we'll do the lab on Monday/Tuesday) and complete the pre-lab questions. 

Tuesday, 2/7/12    Wednesday, 2/8/12

• Much of this semester is going to be spent looking into the way that chemical reactions happen.  We'll start this with a look at collisions and collision frequency.  By looking a a variety of demonstrations, we will see how we can change the frequency of collisions between particles and the effects that has on the reactions we are watching. 

• Homework is from the book.  Read Ch 18.1-4 do problems 1-7, 10-11

Monday, 2/6/12

• Today we will be working on developing our understanding of what it means when a reaction has reached "dynamic equilibrium."  If you did not finish during the regular class period, the questions from the M&M Equilibrium Lab are homework due next class.

Thursday, 1/26/12    Friday, 1/27/12

• Today we will do the Intermolecular Forces Lab in class that will help us see the effects of IMF first hand.  The lab questions will be due on Monday (which is an ALL day!)

Tuesday, 1/24/12    Wednesday, 1/25/12

• Today we will move on to our last topics of the unit.  This means that the unit quiz is coming up!  Make sure you are getting ready by going over the cover sheet for Unit Packet #5.  This unit packet cover sheet will be due on Tuesday/Wednesday next week.  Because it is the end of the semester and so many people will be switching classes and/or teachers, we won't be including quiz corrections as part of this unit. 

• The last topics to cover are Molecular Polarity and Intermolecular Attractive Forces.  These two concepts are closely related and we will practice recognizing them and predicting their consequences in class today. 

• Homework is from the book.  Read Ch 15.13-14 do problems 30-31.  We will be doing a lab next class.  Read through the instructions and complete the pre-lab questions for the Intermolecular Forces Lab.

Monday, 1/23/12

• Today will be the make up day for the classes missed on Friday of last week.  I hope everyone stayed safe and dry!

Thursday, 11/19/12    Friday, 11/20/12   

• Today we will work on the Molecular Models Lab.  This will help you visualize what some of the shapes we talked about last class really look like in three dimensions.  Homework is to finish the lab.  Any compounds that you were not able to make with the model kits can be drawn as Lewis Structures.

Tuesday, 11/17/12    Wednesday, 11/18/12

• Today we will do the Shapes of Molecules activity in class.  This should be finished in class but if any questions were not completed, finish them up as homework tonight.  We will also cover VSEPR Theory that helps us to determine the shape of a molecule with both electron geometry and molecular geometry.  Homework is to determine the electron and molecular geometries for all of the compounds on the More Practice with Lewis Dot Structures WS. 

• VSEPR Table

Friday, 1/13/12

• We will use today's class to revisit all of the content that has been covered this week.  By the end of this week, you should be able to draw Lewis Structures and recognize different types of bonds, be able to differentiate between ionic compounds and molecules and follow all appropriate naming conventions based on the type of compound.

• Homework will be practice drawing more Lewis Structures and practicing the skills of the week with the More Practice with Lewis Dot Structures WS.

Wednesday, 1/11/12    Thursday, 1/12/12

• Today we will clean up questions from last class.  We will discuss many of the details from the reading assigned last class. 

• Homework is reading Ch 15.10-11 do problems 23-27 and fix the Electron Dot Structures WS.

Monday, 1/9/12    Tuesday, 1/10/12

• Today we are talking about covalent bonding.  We will look at telling the difference between ionic and covalent bonding, nomenclature for covalent compounds, and start looking at how to draw structures of covalent compounds. 

• Homework is reading Ch 15.1-5.  Section 15.3 gives directions for drawing diagrams called Lewis Structures.  The Electron Dot Structures WS will give you an opportunity to practice drawing Lewis Structures.  Use information from 15.3 and try drawing each of the structures on the worksheet in questions 3 and 4.  You don't need to worry about questions 1 and 2.  Make sure to give each structure a try...I will provide another set of rules on Wednesday and Thursday and we'll clean up any questions.

• Unit Packet #4 with quiz corrections is due Wed/Thur.

Thursday, 1/5/12    Friday, 1/6/12

• Today we will review during the first half of the class period and then will take the atomic structure unit quiz during the second half.

Tuesday, 1/3/12    Wednesday, 1/4/12

• The lab for today is the Atomic Spectrum Activity.  We will revisit the Bohr Model of the atom and discuss the evidence used to support that model while doing this lab in class.  Any work on this lab that is not finished during class will be homework.

• Unit Packet #4 for this unit is still your chance to revisit old work to see what you are comfortable with and what needs more work.  You will find that the cover sheet for this unit packet looks a little different from past ones you have done. Please compile your unit packet and fill out the cover sheet.  Every student needs a cover sheet for this unit, you can't just make one at the last minute.

Friday, 12/16/11

• We will use today to wrap up electron configurations.  No homework over the break!

Wednesday, 12/14/11    Thursday, 12/15/11   

• Drawing models of the atom can help us to determine the structure it takes.  We will use two ways of visualizing the structure of electrons in the atom.  First we will use Bohr models to draw the locations of electrons around the nucleus and then will use electron configurations to be more specific about electron locations.

• Homework is to draw the Bohr Models for all elements in group 18 and period 3.  Write out the electron configurations for the first 36 elements on the periodic table.  In the book, read Ch 12.1-5 and 13.3  do problems 1, 2, 4, 5, 8 and 9 from chapter 12.

Monday, 12/12/11    Tuesday, 12/13/11

• We will take some time today to revisit the idea of effective nuclear charge and then will use that concept to help predict trends that are seen in chemical properties as we look across or up/down the periodic table. 

• Homework is from the book.  Read Ch 13.1,2,4-7 do problems 12-20

Friday, 12/9/11

• Today we will talk about effective nuclear charge and shielding effects.  A good understanding of how this phenomena works will help you to more easily explain the way that periodic trends work.  We will be covering trends next week.  Homework is to come up with your own analogy for shielding effects and effective nuclear charge.

Wednesday, 12/7/11    Thursday, 12/8/11

• Today we will work on using the periodic table to get information about atomic structure.  Much of what we cover may feel a little familiar as some of this information will be revisiting biology and even middle school sciences.  The homework is the Atomic Structure WS.  

Monday, 12/5/11    Tuesday, 12/6/11

• Today you will have time to prepare your presentation during the first 15 minutes of class with your group members.  By the end of class you should have a pretty complete set of notes on the development of the atomic theory.  Homework is from the book.  Read Ch 4.1-4 do problems 1-9.

Friday, 12/2/11

• We will go over the quiz today in class.  Quiz corrections are due next class as part of Unit Packet #3.

• The next unit will focus on the atom, its structure, and how that structure affects different properties of the atom.  To begin, we will take a look at the history of our understanding of the atom.  In class, you will be given a researcher who contributed to our understanding the structure of an atom.  Over the weekend, you will need to spend some time researching your atomic model and compiling a set of notes that you will use during the next class period, with a group of students who have researched the same model, to develop a presentation for the class.  Your notes will be stamped at the beginning of class.

Wednesday, 11/30/11    Thursday, 12/1/11

• Stoichiometry Unit Quiz

• When you are finished with the quiz, you will work on the Rutherford's Gold Foil Lab.

Monday, 11/28/11    Tuesday, 11/29/11

• Today we will be reviewing topics that we have covered over the past several weeks before the break for Thanksgiving.  We will be reviewing today because we have the unit quiz this coming Wednesday/Thursday.  Your homework is to prepare for the quiz.  Remember, preparation is best done by putting together your worksheets from the unit and looking at each assignment to determine your level of comfort with the content from the assignment.  If you need help, please come in and see me.  Use Unit Packet #3 to help with this.

Friday, 11/18/11

• We'll finish up the MicroMole Rockets Lab today.  Make sure you have had some of your trials measured by the end of the day today if you want a chance for extra credit for the longest launch.

• Homework over the break is the MicroMole Rocket Lab Write-up Questions (at the end of the instructions) which will be turned in along with all of the data that you collected.  The MicroMole Rocket Lab Follow-up Questions and Stoichiometry WS II.  The two assignments related to the lab are pretty short and sweet (you could probably have them done by the end of the day Friday if you plan ahead) but the second stoich worksheet is pretty lengthy.  Don't do it all in one sitting...so don't save it until the night before it is due.

Wednesday, 11/16/11    Thursday, 11/17/11

• Today we will continue working on the MicroMole Rockets Lab.

• Homework tonight is the Limiting Reagents Practice WS.

Monday, 11/14/11    Tuesday, 11/15/11

• We'll be working on a lab all week long this week.  The MicroMole Rockets Lab will be conducted over the three class periods this week.  It is important to remember to collect the data and observations that are necessary to earn credit for the lab.  DO NOT just launch your rockets without recording data on the launch.  Each launch should first be collecting data for the optimum fuel ratio and then collecting data for further improving the rocket launch distance.

• Over the course of the week, the homework will provide practice on the content covered so far this unit.  Remember that all of the content for the unit has been covered already so now it is just practice.  Please make sure to start getting yourself ready for the unit quiz now so that you don't have to squish it all into the week of the quiz which will be the week after Thanksgiving break.  Everyone should be checking work with the keys and/or solutions books and/or coming in for help.

• Tonight's homework is the CVD WS.  It uses a real life example of stoichiometry in the semiconductor industry as a source of practice for stoichiometry problems.

Wednesday, 11/9/11    Thursday, 11/10/11

• Today we will run the Reaction Stoichiometry and Percent Yield Lab. The lab calculations and post-lab questions are due on Monday/Tuesday.

Monday, 11/7/11    Tuesday, 11/8/11

• Today we are going to spend some time talking more about stoichiometry and what it allows us to do in chemistry.  We will also discuss limiting reagents and yields.  We will put all of these together in the lab we will be working on next class.  The Reaction Stoichiometry and Percent Yield lab will be done next class.  Your homework for the evening is to read over the instructions for the lab and complete the pre-lab questions (page 4).

Friday, 11/4/11

• Today we'll introduce STOICHIOMETRY!  It can be an intimidating looking word but its bark is much worse than its bite.  By the end of the year many people would probably list stoich as one of their favorites!

• Homework is to use the new found information from class today to complete the Stoichiometry WS.

Wednesday, 11/2/11    Thursday, 11/3/11

• Today we'll have a guest speaker in for the first part of the class period.  He will talk about opportunities at the OSU Department of Forestry.

• After his talk, we will take the Mini Mole Quiz.

• Homework for today is in the book.  Read Ch 8.1-4  do problems 1-7, 10-11. 

Monday, 10/31/11    Tuesday, 11/1/11

• Remember from the beginning of the unit that, by this week, we should be able to do the mole conversions from the worksheets, etc. without the assistance of the mole roadmap.  If you are still using it, you need to really start practicing the problems without its assistance because you will not be able to use it on tests and quizzes...and we are going to have a Mini Mole Quiz on Wednesday/Thursday.

• To practice even more we will be working on the Holiday Mole Exchange WS in class today.  Make sure you are using the key on the worksheet, the solutions books and your chemistry text to help you!

Wednesday, 10/26/11    Thursday, 10/27/11  

• Today we will conduct the laboratory investigation to determine the formula of the hydrated salt.  All lab data must be collected in class today or arrangements must be made to make up lab work.  Lab Write-ups will be due on Monday/Tuesday of next week.

Monday, 10/24/11    Tuesday, 10/25/11

• We'll actually get started on the Hydrated Salt Lab today.  The first day of the lab is planning what you are gong to do.  We will spend the first part the class today going over the problem that we are trying to solve in the lab and we'll cover some of the safety topics for the lab...both for you and for the equipment.  You will spend the rest of the period planning individually, and then with your partner, a procedure for the lab.  Come to class next time with your plan all ready to go.  Make sure you have a complete data table.  A good data table for this lab will have three data points collected from the lab (i.e. Mass of Crucible + hydrated salt) and two more data points about the two questions, discussed at the beginning of class, whose answers you will need to be able to determine the formula.

Friday, 10/21/11

• Today we will start working on a lab called the Hydrated Salt Lab.

Wednesday, 10/19/11    Thursday, 10/20/11

• It is very important to be comfortable with the prior content covered as it will help you be successful with this next unit.  We will spend time today reviewing work done on the first worksheet and answering any questions that may have come up as you worked.  We will practice more with the Mole Conversions WS which is due Friday.

Monday, 10/17/11    Tuesday, 10/18/11

• Today we will start by going over the quiz that was taken last class.  Your last assignment for the unit is to do your quiz corrections.  With this set of quiz corrections, I would also like you to write a sentence or two about how you plan to either keep your quiz grades up in this class or improve them over the next unit.  Please be sure to do your quiz corrections in a different colored ink so that I can see them easily.  If corrections are done but are done in the same color as the quiz, full credit will not be awarded.

• Unit Packet #2 is due next class.

• After going over the quiz, we will start in on content for the next unit.  We will basically be mashing the last two units together for the next unit.  Stoichiometry takes the math (dimensional analysis and significant figures) from the first unit and applies them to the balanced chemical equations we have been using for the past several weeks.  Today we will learn about an important concept called the "Mole" and then we will practice some conversions using the mole with the Working with Molar Masses WS which is due next class.

Wednesday, 10/12/11    Thursday, 10/13/11

• Unit Quiz! 

Monday, 10/10/11    Tuesday, 10/11/11

• The last of the new content for this unit will be covered today.  We will discuss how you can determine if a single replacement reaction will occur using another piece of information from the back of the periodic table.  You constructed the Activity Series of the Metals from your observations in the lab.  We will make sure we have correct data as it is easy to miss an observation with our lab setup but once you have constructed the series, you can use it to predict if another reaction will run to completion or will not react at all. 

• The unit quiz is next class.  Your homework is to prepare yourself so you are ready to take it on Wednesday/Thursday.  Put together your Unit Packet #2 and take a look through each of the assignments to determine what you have well understood and what needs a little more practice.  Come in and use the solutions book or grab an AO pass/come in before or after school or during lunch or during 1O or 3E if you need some extra help.  The quiz will cover reaction types, balancing chemical equations, ionic nomenclature, and charge balancing formulas for ionic compounds.

Friday, 10/7/11

• We'll use today for a bit of reflection on single and double replacement.  We will be working with small groups to critique our work so far and see if there are any corrections that need to be made.

• Homework over the weekend is practice with naming and formulas.  The Balancing Equations Using Compound Names WS is due Mon/Tue.

Wednesday, 10/5/11    Thursday, 10/6/11   

• Now that we are awesome with double replacement, let's work on the Single Replacement Reactions Lab.  Write-up is due at the beginning of class on Friday.

Monday, 10/3/11    Tuesday, 10/4/11

• Today we will start with a review of naming compounds and determining formulas.  We will also revisit balancing chemical equations and talk about what you all found to be handy tricks when it came to balancing equations.

• Lecture today focused on the five reaction types: Synthesis, Decomposition, Single Replacement, Double Replacement, and Combustion.  Your homework tonight is to apply what you have learned about double replacement reactions and go back through the Double Replacement Lab and re-do questions 2-4, putting correct answers in this time.

Friday, 9/30/11

• Today we will cover balancing chemical equations.  The balanced chemical equation is often the first piece of necessary information for solving problems in chemistry.

• HW is the Balancing Chemical Equations Race.  I know it says it is a race...but it is really just a great set of problems to practice balancing equations!  If you want to race a friend or one of your folks though...go for it!

Wednesday, 9/28/11    Thursday, 9/29/11

• First thing today will be going over the conversions quiz and discussing unit packets.  Unit Packet #1 is due Friday.  The last assignment of a unit packet is quiz corrections.  If you got 10/10 on your quiz, just attach that to the unit packet and you are good to go.  If you missed anything, you need to make the necessary corrections on your quiz paper.  Use a different color marker or pen so that I can see your corrections easily.

• We will discuss ionic compounds today.  There are rules that are followed when ionic compounds are created.  We will learn these rules so that you will be able to move back and forth between compound formulas and their names. 

• Homework for tonight is the Ionic Nomenclature WS.

• The CV Science Department also has a bit of homework for you tonight.  Please print off and who this Donation Request Letter to your parents/guardians.  All you need to do with it is have them write their signature on the letter anywhere and then turn it in on Friday.  Thanks!

• The periodic table from the classroom is posted at the top of the screen.  The front and the back have different information.  You will need both of them.  Print them off and bring them to class each day as you will often want to add your own notes to them.

Monday, 9/26/11    Tuesday, 9/27/11

• We will begin class with a conversions quiz!

• When we study chemistry, we will often have to think about the possible answers and then narrow down to the one that seems to be the best.  This is one of the ways that much of the chemistry we will learn was constructed in the first place.  This process requires a creativity that we do not often get to practice in classes.  Today we will start the Double Replacement Reactions Lab.  We will work on this content in stages.  Today your job is observation and to try to answer the questions as best you can.  Because you do not know how to predict products accurately yet, you will be writing balanced chemical equations by predicting products in ways that MIGHT work!  I want you do come up with a variety of ways that you think the reactants might break apart and come back together to form products.  When you come back later in the week we will look at the way we understand this to work in the real world.  Having through of possibilities before we have the "right" answer will help you start thinking about what works in chemistry and why.  This skill will help you later on in the class when you are faced with questions that you do not know the answer to.

Friday, 9/23/11

• Today we will spend some time reviewing the very important content that is covered during the week.  Being able to run conversions effectively is one of the most valuable tools you will have at your disposal. 

• Homework for the weekend is to prepare for the quiz on Monday by revisiting the two worksheets and sample problems to make sure that you have a solid understanding of how to go about solving these problems according to the method shown on Wednesday/Thursday.  Practicing these problems will take you a long way. 

Wednesday, 9/21/11    Thursday, 9/22/11

• The homework had you run some problems that we call "dimensional analysis" or "conversions."  It is very likely that they felt like problems you have done before many in your math classes.  We are going to spend today's class refining a method for solving those problems in an easy fashion.  As soon as a student develops strong skills in conversions, chemistry becomes a much simpler subject.  I do require that the specific method being shown in class is the method used and shown on all of your work. 

• Homework is practice.  The Using Dimensional Analysis WS is due on Friday.

Monday, 9/19/11    Tuesday, 9/20/11

• We worked on significant figures and measurement last week on Friday.  We will start this week with a further discussion of how significant figures impacts the way we deal with numbers in chemistry.  We will work through another set of models to come up with a set of rules and then will refine those rules into something that is a simple and easy to follow!

• Homework is practice of sig figs and some priming for next class.  The Dimensional Analysis and Sig Figs WS is due next class.

Friday, 9/16/11   

• In chemistry, we use numbers to describe a great deal of our observations.  The number you write down from your measurement tells a great deal about how you made that measurement.  We call this information you get from the number "significant figures" or "sig figs."  We will discuss the rules that you will use to make sure that numbers that you report in chemistry are saying what they should according to your sig figs. 

• The lesson today will be a group activity working through some scenarios and trying to analyze how measurements were obtained and what we can tell from the numbers reported.  If you are gone from class today, you will need to talk to Mr. Kanter about a good way to make up this material.

• Homework over the weekend is in the book.  Read Ch 2.1-3, 6, 13 do problems 1-6, 11, 12, 31, 32. 

Wednesday, 9/14/11    Thursday, 9/15/11

• This class will be time for you to work in the lab on the Boyle's Law lab.  Microsoft Excel is a significant portion of this lab.  If you do not have Excel on your computer at home you can get free programs that are similar to Excel using either Google Documents or Open Office.  Both programs have spreadsheets that you can set up to analyze data.  You can also use the computers here at the school which all have Excel loaded on them.  Whatever you choose to do, please make sure to use your time wisely...this lab is due when you come into class on Friday.

Monday 9/12/11    Tuesday, 9/13/11

• We have some safety topics to finish going over from last week.  We'll start off this week by discussing those last few things. 

• Chemistry is, in many ways, very different from most of the classes you have taken up to this point in school.  We will discuss some of the things you can do to make sure you are setting yourself up for success in this class. 

• Once we are finished with all of that, we may as well get down to the science!  We will use a short topic of "Gases" to get you all introduced to the laboratory technology you will be using during the course of the year.  We'll take a look at the lab equipment and go over the beginning of the lab.  When you come to class next time (Wed/Thu), make sure you have read over the Boyle's Law lab instructions so that you can get as much done as possible in the class period. 

Thursday, 9/8/11    Friday, 9/9/11

• Today we will discuss safety in the chemistry laboratory and introduce everyone to many features of the classroom. 

Wednesday. 9/7/11

• Students attended a general orientation to CVHS science department policies at the stadium bleachers.

• As homework for this first day, students are to do the following things for the next scheduled class period:

1. Read the Class Syllabus posted here (a hard copy will not be provided, nor will it be needed -- SAVE A TREE, JUST PRINT THE PAGE TO SIGN).  Bring your questions for the next class period.
2. Print, read, and then sign the Safety Contract and the Science Department Drop Policy.  Have your parents sign these contracts as well.  Signed contracts are to be returned to class prior to participating in lab activities.
3. Send Mr. Kanter an email (be sure to indicate who you are and which class period you are in) so that he can enter it into the grade book.  Mr. Kanter's email is Ryan.Kanter@corvallis.k12.or.us.
4. Have your parents send Mr. Kanter an email so that he can place it in the grade book as well.  You can include your parent's email in your email as long as it is a working email address.
