Welcome to Chemistry! My name is Lezlie Haynes and I am the instructor.
Happy Thanksgiving! See you in two weeks.
11/16–see the email I sent for info. Follow agenda for hwk.
11/9–today was a full day again. Students turned in Wksts ABC and I handed out a notes sheet and then Wkst DEF. We then reviewed writing formulas and naming compounds. After several examples, we moved on to balancing chemical equations. I worked close to half of Wkst D and at least 1 or 2 on wkst F. Remember, on Wkst D you are to write the chemical formula names and then balance the equation. I will hand out the answer sheets next Tuesday to those at Tutorial. If you aren’t at Tutorial, you can either come by to get yours, have a friend pick yours up or get it on Thursday. We have honors students that can tutor any student that is having difficulty. Hwk is to follow the agenda. I think there is an honors lab next week. If I am right, honors students need to sign up in advance.
11/2–In class: students turned in the molar mass worksheet (effort grade) and I handed out 2 ion sheets and 2 sets of notes sheets for the lesson today. I also handed out wkst’s A, B, C for homework. I lectured over how to write molecular formulas and names (covalent) and ionic compound formulas and names. We went over what to do with transition metals, too. Hwk is to follow the agenda.
10/26–Today in class students took the final elements quiz, then we went over the molar mass worksheet. Students that were not finished were allowed to it home and complete it. It is due next week. After going over the worksheet, we reviewed how to do lewis structures then covered VSEPR theory. Students were given handouts to help with the info as well as used a previous handout to work example problems. Hwk is to follow the agenda.
We begin the next unit next week. This is a fundamental unit in chemistry. We are beginning to learn how to write chemical names and chemical formulas. This is always a struggle for a lot of students so please be aware of what your child is doing over the rest of this semester. Success in the next 6 weeks will mean success for the rest of the year. Unit 4 is foundational information. Students will not succeed second semester if they cannot write a chemical formula, chemical name, or write a balanced chemical equation.
Happy Mole Day!!!
Mole Day is an unofficial holiday celebrated among chemists, chemistry students and chemistry enthusiasts on October 23, between 6:02 a.m. and 6:02 p.m., making the date 6:02 10/23 in the American style of writing dates.
10/19–Today in class, students turned in their gum lab and took quiz unit 3B. I lectured over atomic mass, atomic weight, molar mass and avogadro’s number. We then went outside and performed a simple lab using sidewalk chalk to reinforce molar mass. Hwk is to follow the agenda. Work on the handout I gave today in class.
MOLE DAY is Monday, October 23 at 6:02 am at IHOP. Be there and in my picture in front of IHOP before 6:02 am for bonus credit. Stay for breakfast with the group–it is lots of fun. Parents are welcome to stay and eat, too. I am not buying…they buy their own breakfast!!!
10/5–Today was a really full day. Students first took quiz A, turned in wkst A and B, then I lectured on periodic properties, types of covalent bonds, ionic bonds, lewis structures, how to determine where a molecular formula is ionic, polar covalent or pure covalent, then worked on the bubble gum lab on lewis structures.
Students seemed to have some trouble on this so you might check on them and make sure that they don’t wait until 2 weeks from now to look at their chem again…Hwk is to follow the agenda and complete bubblegum lab (lab name on agenda might be different). We will take quiz B when we return. This will have the following types of questions:
2 electron configurations (yes, you can use noble gas configuration), 3 – 5 lewis structures (2 – 3 single atoms and 2 – 3 compounds with at least one ionic and 1 covalent).
9/28–We had a great day (or I did!) today. In class we reviewed the 4 quantum numbers, electron configurations and orbital notation. Then, we moved into learning about how the periodic table relates to quantum mechanics, valence electrons, octet rule and lewis structures. We did not quiz today but will quiz next week. The quiz next week will have one problem asking for the 4 quantum numbers, some electron configurations, a question or two about the quantum numbers (what they are, how many electrons are in sublevels, # of orientations per sublevel, etc). Due next week will be the two worksheets A and B. If you need help, come before Tutorial Tuesday. There will be at least one honors student there to help even if she isn’t scheduled….Olivia is always there early. 🙂
9/21–Today was a great day–we started quantum numbers, orbital notation and electron configurations. We spent the entire class working on those three things. Homework is to follow the agenda–I made a few modifications to the back side of the worksheet. Students should have taken notes and know what to do.
This content is not easy and it is important that students work on this every day. I would recommend studying in pairs and coming to Tutorial early on Tuesday and Thursday to work together (no earlier than 8 am). No quiz next week.
Honors–Notebook check of content through today is next week. Make sure your notebook is organized following the handout.
Progress reports went out today. Please email me if you have questions.
9/7–today was a very full day. In class, students completed Chromatography lab and performed a second set of experiments. They took Unit 2 Quiz 2 and we also reviewed for Unit 2 Quiz 3 which is just a matching quiz over the periodic table info. Hwk is to follow the agenda. Could be an easy week b/c the hwk is to finish up anything in Unit 2 not finished yet ie reading, OYO’s, reviews or PP’s as well as the lab from class.
8/31–Yesterday was a very full day! In class, students completed about 3/4 of a chromatography lab, took quiz 2 for Unit 2, turned in Wkst 1D, took notes that went through the rest of the unit notes sheet and watched a 15 min video on the history of the periodic table and Mendeleev. I really love the history of science–especially chemistry. Hwk is to follow the agenda. There is no work to do for the chromatography lab b/c it isn’t finished. If needed, you can use Google to help you complete wkst 2A. You will turn in your student notebook next week for Ms Kim to grade the lab we did last week. Make sure you finish the conclusion–you get an extra week. Lastly, notice that Elements Quiz #2 is next week. This will be over: Elements #13 – 20 plus iron, manganese, cobalt, nickel, copper, zinc and a review of the first 12.
Honors Students: Those of you that signed up to do the honors component need to turn in your tutoring dates by next week. Read the honors handouts carefully. You are responsible for recording your tutoring dates in your phone or planner and then showing up. I will hand out the 1st six weeks notebook check sheet so that you know what to expect and how to organized your notebook. Also, you must preregister for honors labs so that I know how many to plan for. I am excited about the honors option. It is always fun to get to do more lab work.
All Students–after I get the tutoring dates from the honors group, I will make a master list and hand it out so that every student knows the day and time of the free tutoring.
8/24–we had a good day today. Days we can perform experiments are always better. In class we reviewed sig fig rules, took quiz 1C, turned in Wkst 1B and 1C and the Pi lab, began lecture over Unit 2 (Energy and matter, mass, laws of conservation), watched a short video segment on Lavoisier’s discovery of law of conservation of mass then performed Exp 2.1. Hwk is to follow the agenda–make sure to study for vocab quiz over the first part of the notes (everything up to but not including states of matter), complete Exp 2.1 in SN (student notebook)–make sure you write a solid conclusion. Read the info in the module after the lab–author normally explains the lab there. If you need a format to follow, click on the Science Fair Report Handout on the Science Fair 7-12 page on the website.
8/17–great day! Follow agenda for hwk.
Bonus Opportunity: Monday, 8/21 is the Solar Eclipse. If you take a pic of yourself outside during the eclipse and send it to me, you’ll get 5 bonus points. I’ll post them on the chem page. I’d like a pic of you with a sign with Eclipse 2017 or something similar. With solar eclipse glasses will get you 2 extra points. I plan to take my selfie during ‘Totality’!!! Videos work, too!
If you do not have glasses, you can make a pinpoint projector and watch the shadow on the ground instead of damaging your eyes looking at it.
8/10: Great first day! In class we went over class rules, metric system and dimensional analysis, how to use the calculator, review of sci notation and how to take measurements with different items. Students worked on a measurement lab–if the lab was not completed in class, students should plan to come early (8 am) on Tuesday or next Thursday to complete the lab. Wkst 1A was handed out; quiz 1A was taken. Hwk is to follow the agenda.
Prior to the start of class, Thursday, 8/10, please print and read the following. If a signature is required, do that as well. Bring all print outs to class the first day of class:
For those interested in the Science Fair or the Honors option which requires a research plan with experimentation:
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!
