Tuesday, 10/24    Wednesday, 10/25 (2hr Late Start Days)

• Proficiency Opportunity: Balancing Chemical Equations 1

• Ionic Nomenclature Guided Learning Activity-- This is due on Tue/Wed next week.  As you work through the questions, use the booklet we made in class (directions below if you still need to make one) to start writing down your rules for naming the different types of ionic compounds(Representative Ions--Grps 1-2, 13-18; Polyatomic Ions; and Transition Metal Ions). Polyatomic ions are not covered in the worksheet, but once you get the other two...you can probably figure out what you need for polyatomic nomenclature. 

Monday, 10/23

• Weekly Practice 2.2

• Come to class prepared for the weekly review and quiz.  

• After the quiz, you'll have the lab instructions and checklist for the lab we'll run later this week.  Come to class on Thu/Fri ready to do the lab with all of the pre-lab portion of the checklist completed.  

• You'll notice that we have a few repeated items this week from last week as we had to make a few changes of plans.  We'll pick up any of the things we missed or didn't complete last week.

Thursday, 10/19    Friday, 10/20

• Proficiency Opportunity: Balancing Chemical Equations 1

• Today we'll spend some time wrapping up and practicing the material covered over the last couple of class meetings.

• The new material for the day is balancing the overall chemical equation (in addition to the charge balancing we have already covered) and we will also look at ionic nomenclature--chemistry's way of saying "naming ionic compounds."

• Ionic Nomenclature Guided Learning Activity-- This is due on Tue/Wed next week.  As you work through the questions, use the booklet we made in class (directions below if you still need to make one) to start writing down your rules for naming the different types of ionic compounds(Representative Ions--Grps 1-2, 13-18; Polyatomic Ions; and Transition Metal Ions). Polyatomic ions are not covered in the worksheet, but once you get the other two...you can probably figure out what you need for polyatomic nomenclature. Booklet and GL WS are due on Tue/Wed next week.

  • Bonus (but not optional) HW Assignment: For those three rxns from the lab, balance the overall equation AND name the products that were produced.  (These three complete reactions and the rest of lab work you did initially should be turned in with your weekly practice on Monday.)

• Notes on Balancing Chemical Equations and Ionic Nomenclature

Tuesday, 10/17     Wednesday, 10/18

• Proficiency Opportunity: Scientific Notation 2

• We will spend these next few classes working toward writing complete and correct balanced chemical equations. We will start today with what you have to do when you predict products. Many of the reactions we are working with involve ionic compounds and those compounds must be charge balanced. With some reaction types, you can also predict whether the reaction will occur or not. Today we will look at how that can be done with double replacement reactions.

• Charge Balance and Solubility Rules Notes

  • Bonus (but not optional) HW Assignment: For those three rxns from the lab, look at the products you produced and see if they are correctly charge balanced.  Correct any errors.  Add in notations of "aqueous" or "solid" for the products produced.

Monday, 10/16

• Weekly Practice 2.1

• Today in class we'll go over the ideas that you came up with during the lab on Monday and Tuesday. Chemists have Five Reaction Types that describe the chemistry that happens in a wide range of reactions. We'll take a look at these five reaction types today and will practice using those reaction types to predict what the products of a chemical reaction will be. Over the next week or so, we will develop skills necessary to write out accurate and complete balanced chemical equations.

• Chemical Reactions and Reaction Types Notes

  • Bonus (but not optional) HW Assignment: Pick three rxns from the lab and predict products using the appropriate rxn type pattern.

Thursday, 10/12    Friday, 10/13

• Today we will be starting to look at chemical reactions. We will start with the Chemical Reactions Lab. This is a lab that encourages you to put yourself in the shoes of the first scientists to approach a new problem. We'll use this lab to practice coming up with possible options and then will spend some time on Wednesday and Thursday deciding which of our possibilities is the most reasonable and why.

  • LAB QUESTIONS ARE DUE THIS COMING MON--That is unusual but we will be doing some stuff with them in class.

Tuesday, 10/10     Wednesday, 10/11

• No Weekly Practice this week...the lab will take it's place this week since we only meet twice.

• Come to class prepared for the Atomic Structure Unit Test.  We'll be getting going on it right away! :)

• After the test, we'll spend the rest of the period learning about ionic compounds and chemical reactions.  Next class you'll get to see a whole bunch of them!

Thursday, 10/5    Friday, 10/6

• Weekly Practice 1.4--DUE TODAY

• Today we will spend some time reviewing during the first half of class. Come to class with your self evaluation sheet and any questions you have come up with. That will help make our review time more helpful for you!

• We'll be taking the test for the unit during the second half of class.

Tuesday, 10/3     Wednesday, 10/4

• Today we will cover the question: How do we know about atomic structure?

• Neils Bohr modeled the atom (we have used his model a bunch!) and ran some calculations about what you would see the electrons do when they were excited by high voltage electricity. We will look at the emission spectra of hydrogen and a few other elements and take a look at the light produced to provide evidence that our model of the atom is a pretty good one!

• Atomic Spectra Animation Slide from class--you'll have to open this in PowerPoint and run the slide show to see the animation.

• Atomic Spectra Activity--Lab Sheet (Due Wed/Thu of Next Week)

Monday, 10/2

• Weekly Practice 1.4--you will want to get a jump on this weekly practice as it is due on Wed/Thu when you come for the test.

  • There are a few questions on the Weekly Practice this week that are listed as "Challenge" problems. That does not indicate that they are optional but just is to let you know that they won't be an immediate piece of cake. Everyone needs to give them a try and have an idea down for all questions in order to get full credit. :)

• Come to class ready for the weekly review and quiz!

• This is the last week of the Atomic Structure Unit. That means this coming Thu/Fri is the Unit Test. Remember that while you can use notes, homework, and other resources on the weekly quizzes...it is just you, the yellow PT, and your calculator on the end of unit tests. We need to take a few minutes and reflect on where we stand. Preparing for chemistry tests starts with thinking about what you have down pat and what you need work on. Use the Chemistry Test Review--Self Evaluation to help guide this process. Your Self Evaluation is DUE with your test on Thu/Fri

Thursday, 9/28    Friday, 9/29

• Two weeks ago we talked about some of the lies you are told about atoms when you are in middle school. We'll spend a bit of time today learning about Electron Configurations. This is a way we have of accounting for how many electrons are in an atom and where they are in the electron shells. We'll use a tool called an Aufbau Diagram to help us determine the electron configuration for an element.

• Quantum Model and Electron Configuration Notes

• We will also talk a bit about the Quantum Model of the atom which is our most accurate model as far as we understand the atom today. It is a very odd model and I'll help you to know which parts you are responsible for knowing and which parts are just cool to think about in class!

• We'll spend a bit of time today also revisiting the periodic trends we covered last week.

• This video is a great look at some of the funkiness of the Quantum Model!

Tuesday, 9/26    Wednesday, 9/27

• Today we will take a quick look at how we currently understand atoms (and especially electrons around atoms) to look.  This will lead us to "electron configurations" which give a more accurate way of looking at how electrons fill the shells that we are putting into our Bohr models.  

• Electron Configuration Guided Learning

Monday, 9/25

• Weekly Practice 1.3

• Come to class ready for the weekly review and quiz!

Thursday, 9/21    Friday, 9/22

• Proficiency Opportunity: Sci Not 1 (again!)--Scientific Notation Notes just in case you want them! :)

• Today the focus of class will be using effective nuclear charge to predict relative properties of elements. We will look at a few properties in particular:

  • Atomic Radius (Size), Electronegativity, and Ionization Energy

We call these "Periodic Trends" because they tend to change in predictable fashion as you move across the PT. Many people try to memorize the direction of the trends and use those memorized facts to answer questions. This is a good opportunity though to practice logically reasoning through how effective nuclear charge changes properties of an atom. Less memorization is nice (and you'll be able to put these ideas back together later without having to resort to looking up facts that you may have forgotten).

• Periodic Trends Notes

Tuesday, 9/19    Wednesday, 9/20

• We'll be looking at the Periodic Table during class today. If you haven't already, you should definitely come today with a printout of the Periodic Table from the links on top of the website!

• Today we'll be taking a look at Effective Nuclear Charge. Zeff is an important characteristic of atoms that we will use many times throughout this unit and the rest of the year to predict a variety of properties about atoms. We can use Zeff as a tool to predict properties like the relative size of atoms (we'll do that this week!) all the way to things like the relative strengths of acids (we'll do that waaayy later in the year!). It is a powerful tool that you'll want to make sure you can use!

• We'll model effective nuclear charge in class today and spend the second half of class making a drawing of your own analogy--similar (but different) to the one we used in class. Your drawing will be due next class if you don't finish it during class time.

  1. Your analogy should have something that represents protons, electrons (shielding and valence!), and distance. I should be able to take a look at your analogy and see how the attraction to the nucleus changes because of shielding and distance.

• Effective Nuclear Charge Notes

Monday, 9/18

• Weekly Practice 1.2

• Come to class ready for the weekly review and quiz!

Thursday, 9/14    Friday, 9/15

• Proficiency Opportunity: Sci Not 1--Scientific Notation Notes just in case you want them! :)

• Today we'll spend a bit of time with your group wrapping up the Guided Learning assignment that you started last class.  Then we'll go over the process of calculating average atomic mass all together and practice a few problems.

• Average Atomic Mass Example Problems

Tuesday, 9/12     Wednesday, 9/13

•  Proficiency Opportunity: Bohr 1

• Today we'll continue looking at the structure that makes up atoms. We talked about isotopes and how we can use information about isotopes to determine how many neutrons are in the nucleus. We will also use isotope data to help us calculate the average atomic mass that we find on the periodic table.

• We will learn that calculation by doing our first Guided Learning Activity of the year today. Occasionally we will start a topic with a set of data or a model that we can look at and start to work on developing our understanding of how something works before we hit the same topic in the notes. Today we will do that once we are solid on Isotopes with the GL Activity on Average Atomic Mass. We'll take a look at how the average atomic mass on the Periodic Table is calculated.

Monday, 9/11

• Weekly Practice 1.1 --You don't need to start this before class today...we haven't covered this information until today's class. :)

• We'll take a look at what most Mondays will be like...we have a pretty solid routine that we'll follow.

• We'll start in on the real chemistry! First we'll look at atomic structure and how we can find out what and how many particles make up an atom. We'll also start looking at how we can use the periodic table as a helpful tool in Chemistry. Atomic Structure Notes

Thursday, 9/7    Friday, 9/8

• We definitely didn't get through all of the things we started on the first day...we'll wrap that up today: 

  1. Orient everyone to the classroom with the Mr. Kanter's Room Science Scavenger Hunt.  We will use what we find to make sure that everyone is safe in the lab.

  2. Go over the way the class will work this year and how things like homework, quizzes/tests and labs will be run. 

  3. Finish with a "really tough" quiz.

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

  1. If you haven't already, please fill out my Google Form to show that you found the website and to give me some information about yourselves. 

  2. If you'd like, check out the course syllabus on the Class Resources page in Canvas.

• We don't really use a textbook but we do have one available as a resource that may be helpful at home.  If that sounds like something that you might want to use at home, you can grab one from the library bookroom.  

Tuesday, 9/5     Wednesday, 9/6

• Welcome to General Chemistry!  We have a lot of exciting things to try this year in class. 

• Today we will start with an introduction to what you might expect to see during the year in Chemistry. 

• After the course intro, we will jump right in with a LAB on the first day.

• With the rest of the period we will aim to accomplish a few things:

  1. Discuss observations from the lab and any interpretations that we could make from them. 

  2. Orient everyone to the classroom with the Mr. Kanter's Room Science Scavenger Hunt.  We will use what we find to make sure that everyone is safe in the lab.

  3. Go over the way the class will work this year and how things like homework, quizzes/tests and labs will be run. 

• Your homework tonight is to fill out a Google Form to show that you found the website and to give me some information about yourselves.
