Lezlie Haynes

Welcome to Chemistry!  My name is Lezlie Haynes and I am the instructor.

4/23–hwk posted in GC.  Went over beginning of Mod 12 and worked some heat problems.  Went over the lab.

4/16–we are going to spend another week on redox reactions.  I have posted a wkst on GC with the key for you to work thru this week.  We will take the second quiz over all of Redox next week.  Complete the first redox quiz this week/Thursday and have parents grade.  You can use your book and notes to help you on the quiz.  Omit #11 on this first quiz.

4/2–Chem hwk is posted on Google Classroom.  Parents will grade the work assigned.  I will send keys for wkst and lab later in the week.  If you did not pick up materials at Tutorial during spring break, go to our chem page on the Tutorial website and print off Notes for Mod 16–it contains notes sheet and the worksheets for the module. Notes are at bottom of page.

3/26–I have updated the class in Google Classroom. I have posted a link to a Zoom meeting Tuesday at 1 as well.  Check email and GClassroom for the code.

2/27–In class–students took their quiz and turned in their work.  They performed a lab on creating a solubility curve using potassium nitrate.  I think they did well–most had a low percent error.  After the lab, we went over the concepts of molality, freezing point depression and boiling point elevation. I worked 2 problems from the Practice Problems (8 & 10 I think).  Hwk is to follow the agenda and  study for quiz next week over solubility, molality and temperature problems (If you missed class, you need to read thru the notes and work the practice problems to prepare for the quiz), complete the solubility handout.  You can use a notecard on the quiz for the molality and temperature problems.  The card can have the formulas and notes but NO example problems to follow.  You will turn in the card with the quiz.  Check your emails–I will link some videos for further practice on molality and temperature problems.

2/20–In class– students turned in their quiz from Mod 9, lab from last week and (were supposed to turn in) EPP.  Many said they had no idea what EPP’s were or where to find them.  EPP are Extra Practice Problems are they are in the back of the textbook.  For those that did not complete them this week, turn them in next week.  Next, I handed out quiz B for Mod 9 and some notes handouts for Mod 10.  I used a PPT to go over info from Mod 10 and we practiced reading and interpreting a solubility curve using the handouts.

Hwk–follow the agenda.  Complete the quiz and work on Solubility Wkst.  We will have lab next week and, hopefully, work on more content from the module

2/13     In class–we talked about stepping back a little and reviewing prior concepts more in the upcoming weeks.  Then, we performed titration labs and sent the Mod 9 quiz home to be taken and returned next week.  Hwk is to follow the agenda and complete the Mod 9 quiz.  We have a quiz next week on Molarity and Dilutions.  I will email some sample questions for you to practice.

 

2/6    In class–after the quiz, we talked about Molarity and Dilution problems, I worked several examples, handed out a notes sheet then we performed Exp 9.2 in class.  Remember, read the two pages after the lab in the textbook to better understand what we did in class.

Hwk is to follow the agenda.
Bonus–using 0.8M Vinegar as the concentration of our acid today, determine the concentration of ammonia used in lab.  Results will vary by group as different groups stopped their titration at different end points (colors).
1/30     Today was a good day!  We started a new module on acids and bases.  Students watched an 8 minute video explaining what pH means and how it relates to acids and bases.  I handed out Neutralization reaction worksheet and we worked 2 I think.  We went over most of the first page of the notes sheet and started talking about how to name and write acids.  We ended class with exp 9.1.  Students should finish the lab at home (the conclusion).
Hwk–follow the agenda.  Quiz next week on Limiting reactant, percent composition, empirical and molecular formulas.

1/23     In class–students took the quiz over Wkst A (stoichiometry), then I taught on percent composition, empirical and molecular formulas.  We worked the problems on the Stoichiometry notes sheet and I handed out two wksts for homework.  After we went over the lecture material, students performed a % sugar in bubblegum lab.

Hwk is to follow the agenda.

 

1/16     In class–we reviewed stoichiometry as we worked on limiting reactant problems.  We worked 2 off of the worksheet handed out in class then students performed Exp 8.1.  Hwk is to follow the agenda.

We decided not to take up Wkst A today so that students could have more time to practice the concept.  We will take up wkst B next week.  Quiz next week:  there are six multiple choice questions.  4 of the questions have balanced chem eq, 1 is unbalanced but given, and 1 is not given so students have to write and balance the eq.  Of the 6 questions, 2 are mole-mole style problems, 1 is Liter-liter and 1 is grams to grams.  Students may make a notecard with the gramsA-molA-molB-gramsB stuff I wrote on the overhead today.  On the back, you can include a gram to gram sample problem.

In class–worked stoichiometry problems

Hwk–follow the agenda.  Review writing formulas, naming compounds, writing and balancing chemical equations, print the Stoichiometry notes.  PRACTICE, PRACTICE, PRACTICE!

Welcome to Chemistry!

“This course is designed to be a first-year high school chemistry course and gives the student a rigorous foundation in chemistry, in order to prepare him or her for a college-level course.” Apologia website

Organization is very important and students are required to keep a binder with sections for notes, quizzes/tests, and worksheets. Students should bring their textbook, student notebook, binder, calculator and pencils to every class.

This course has been formatted a little differently from previous Tutorial science classes. I have organized the content into units. Each unit will begin with lecture and a handout that covers the important concepts. For units with math content, multiple examples will be provided. Students will complete the On Your Owns in the textbook as well as Review Questions and Practice Problems. Additional worksheets will be assigned to reinforce difficult concepts or provide additional in-depth practice. Students will be quizzed multiple times per unit and quiz dates will be listed on the agenda. Multiple experiments will be performed that will enhance student understanding of chemistry concepts.  Comprehensive final exams will be administered at the end of the fall and spring semesters.

This course has additional content added to enhance the content in the textbook.  Serious thought and planning has gone into deciding what content to add and why. All added content will better prepare the student for college level chemistry.

I look forward to seeing each student in the Fall!
