May 20: last five day week of school without testing. We will continue the pattern of last week: bell-ringers, discussion, review activities (including powerpoints, online interactions, some writing, summarizing and presentations, etc.) and assessments, both paper and online. Don't forget to submit any review packets and online efforts, as directed when assigned.
Exam blitz is next Tuesday, Wednesday, and Thursday after school, 250-345pm...if you desire some small group time, asking questions, this is the deal! I just need for you to let me know which days, and any particular questions, so that I can ensure having good materials for your support!

May 15: we continue our efforts for review. 11 days left, including today. Here is a resource, thanks to Mrs. Gartner, which may help on some topics, for better understanding: https://interactives.ck12.org/simulations/chemistry.html
May 13: we are near the end of the semester. We will finish discussing oxidation/reduction and electrochemistry today, review nuclear chemistry, which we covered last week, and continue our test preparations, which were done in my absence Thursday and Friday. Henceforth we will work on our test-taking strategies as well as our content review every day. I am planning on using Quizlet Live, Socrative, and possibly other interactive resources. We will also integrate released test efforts in our preparation. Powerpoints from this week will be below. Other useful files will also be posted.

Week of May 06-10: my expectations for this week are to finish our discussions of solutions, including acid/base, buffers, then moving through nuclear chemistry (including a short half-life lab), and starting our general review of the semester. Thursday and Friday classes will entail small group work in test-taking strategies while I am away attending my youngest daughter's college graduation events. We will continue next week in our general review preparations for successfully assaying the North Carolina final exam!
May 02: excellent, but long, reading on the second law of thermodynamics, from a retired professor of Physics, below. Also, far right, is site for today's lecture on acids and bases: http://www.utdallas.edu/~son051000/chem1312/Chapter16a.pdfwww.utdallas.edu/~son051000/chem1312/Chapter16a.pdf

Week of April 29-May 03: I expect we will finish reaction equilibria, rates, and have a better understanding of collision theory and Le Chatelier's principle; we may also start on acids/bases, including buffers, and, again, we will be tying this to much prior knowledge that all of you possess. Chapter assignments were given last week, already on this site, and there will be handouts in class as we continue on our course through chemistry. Almost to review time.
April 29: hope everyone had a good spring break...as usual, it went by quickly. Here are several sites to visit, read, and be ready to discuss later this week...Friday, our short day, will be great for this discussion.

April 17: last day of fifth six-weeks of the school year. Time to line up balance of school year, as only 1.5 days yet this week, then spring break, come back and many of you (8) will be affected by AP tests. Here is our line-up:
- Chapter 17: read/notes, vocabulary (you should know most of these already), 3, 4, 12, 14, 18, 22, 32, 45, 51, 60, std. test prep (1-10)
- Chapter 18: read/notes, vocabulary, 2, 4, 6, 7, 12, 13, 21, 22, std test prep (1, 2, 3, 5, 6-10)
- Both due May 3rd, 8am
- Chapter 19: read/notes, vocabulary, 4, 5, 6, 7, 9, 10, 11, 13, 17, 27, 29, 30, 34, 35, 41, std. test prep (1-13)
- Chapter 20: read/notes, vocabulary, 1, 6, 10, 11, 18, 23, 24, std. test prep (1-11)
- Chapter 21: read/notes, vocabulary, 3, 18, 20, 26, std. test prep (1-7)
- Chapter 25: read/notes, vocabulary, 4, 7, 8, 12, 14, 28, 43, std. test prep (1-8, 13)
- All four due May 14th, 8am
- Chapters 22-24: flip through, read captions and look at pictures, I will briefly discuss so that you have some exposure to organic chemistry.
April 16: tomorrow's test: almost all of the material is actually relevant to chapter 13, even though a few of those with calculations are from 17, but are right out of the lab you are working on, and are simple Q=mC deltaT problems. BE aware of phase diagrams, triple points, phase changes, the movement of energy from one thing to another (energy transfer...nothing more) and realize what temperature is a measure of, on the molecular level, and I will be certain that all will do surprisingly well. The reality of energy in chemistry vis a vis phases and measurement, is that it is much simpler than many of the topics you have already managed to get handles on; I am confident you will agree after you finish tomorrow. (And, yes, I just looked over the test to find these items for you to look at. Review chapter 13, look over key concepts in 17...all of you will be fine. Just reword what they are looking for in each question...then answer.)
April 15: Sorry I am late posting this week. I focused on getting grades tabulated, into PowerSchool, and setting up today's lab.
|
April 15: 811am: I have put in that work which I have received, and can find. If you feel that I have missed something, let me know ASAP. (I still have to add extra credit from grocery efforts)
|
April 12: it is 117 pm. I have this week's bell-work (in 232pm), yesterday's lab (in 232pm), calculation practice sheets (in232pm), and submitted grocery expeditions to grade; otherwise, all grades that I think I have are in powerschool. If you see either a blank, a "1", or something lower than you think it should be, you need to see me Monday.
April 11: don't forget that the questions and calculations from today's lab are due tomorrow. Short class due to prom....
April 10: chapter 16, read/notes, do vocabulary, problem 63, std. test prep: 1-7, 15. Due Monday, April 15. Lab tomorrow, short School Net effort, lecture on thermochemistry Friday during shortened class.
Updated April 09, April 07: another busy week...seems I should change this...how about we continue to move as close to light speed as is possible for mere humans, as we move from solutions into thermochemistry. Watch due dates. I will add assignments later (written 1131am Sunday)
- Monday
- study guide time: solutions, for short test TOMORROW: focus will be on concentrations, dilutions;
- optional activity: forensics analysis (unless more time allotted for review)
- Tuesday (I will be leaving to drive Lacrosse team to First Flight, and will try to get some grading done in the afternoon/evening, but may not finish)
- solutions test
- visit: https://www.slideshare.net/sqjafery/unsaturated-saturated-and-supersaturated-sowww.slideshare.net/sqjafery/unsaturated-saturated-and-supersaturated-solutionslutions take notes after test. Will hit this Wednesday...test went very well Tuesday, little to explain
- Wednesday
- continue on saturation, solubility: measurements and graphs, as opposed to our earlier understanding of yes/no
- Thursday
- go over test, as I may not have everything ready for Wednesday's class
- short School Net Assessment on solutions
- Thermochemistry: time to heat up our understanding of chemical reactions/interactions: introductory ppt, discussion
- Friday
- Thermochemistry: turning the heat up: more lecture
- Thermochemistry: discuss upcoming lab: two-three day lab next week
April 07: just a reminder: test Tuesday. It will only be on solutions, so we will go over everything Monday. Bring your questions!!
April 04: this file, to the right, will explain more on bonding and domains. Long but very much worth the time to completely watch.

April 04: really neat site for VSEPR: https://winter.group.shef.ac.uk/vsepr/high-cn.html
|
March 31: another busy week coming. Please take note of due dates.
- Monday
- study guide time: what else do we need to talk about for Tuesday's test?
- look over Friday's School Net Assessment, discuss results/questions
- Tuesday
- test: electron, VSEPR, gas laws
- HWK: chapter 15: read/notes, vocabulary; 3, 6, 7, 12, 14, Pg. 464: graphic organizer, 22, 33, 34, 43, 56, 61, 70, 74, std. test prep; Due Friday, April 05.
- Wednesday
- go over Tuesday's test
- Chapter 15 lecture: Water and Aqueous Solutions;
- Thursday
- Several demonstrations, continue lecture on ch. 15 topics: electrolytes, colloids
- Friday
- Finish lecture
- Work on study guide for test on Tuesday, April 09
March 25: busy week coming: States of Matter Monday, hopefully going through most, if not all, of chapter 13; problems: 1, 13, 17, 19, 24, 26, 36, 49, 55, std. test prep, all due Thursday, same as lab report. Either Tuesday or Wednesday, we will move into chapter 14, which would be better entitled, "Gas Laws, or how we can find ways to calculate all sorts of stuff about gas phase matter." While I think I normally mention how important vocabulary is, these two chapters are loaded with important terms. Let me see flash cards or some other vocabulary effort by next Monday, April 1st (no fooling!). I expect that you all will feel the pressure on gas laws, and these will complete our week. Chapter 14 problems: 5, 8, 9, 11, 13, 20, 23, 29, 31, 38 (by Friday, if not sooner); these are to be able to follow along, so do as we hit the material; I will have other problems for greater challenge later in the week to hand out. Don't be a fool and forget lab paperwork...due Monday, April 1st! Earlier garners some XC so don't miss out! VSEPR review packet due no later than April 1st.
March 22: see below for file of data from today's lab...it is all that I received. Updated March 25...two more groups!

March 19: I missed listing my expectations for the week yesterday...too excited for VSEPR, I guess. More on VSEPR today, inter-molecular attractions, some practice work, and some real world problem solving...a forensic effort. We also have a stoichiometry lab...try not to pop extra balloons. These will lead us into behaviors based on the state of matter of a given material, which then continues into gas laws, a study of kinetic energy and how it relates to the properties of volume, temperature, and pressure, and, ta da, how we calculate these any a given set of conditions. This will likely finish out the first half of T5 for us.
March 18: Review 5.2, 7.1, 8.2 (most important)
Exceptions to Octet Rule: referring to central atom, high end, only:
Exceptions to Octet Rule: referring to central atom, high end, only:
- Phosphorus: 5 electron domains, trigonal bipyramid
- Sulfur: 6 electron domains, octahedral
- Likely also selenium, tellurium
- Chlorine, bromine, Iodine: 7 electron domains, pentagonal bipyramid possible
- Xenon: up to as many as you can…never heard of 8 electron domains, usually 6 or less; XeF2, XeF4, possibly others
- Krypton: typically 4 electron domains, typically as KrO2,
- Li, Be, H, He: only room for two electrons (referred to as “Duet” rule)
- Boron: happy with 3 electron domains, 6 electrons…think small atom
- Nitrogen: only 4 electron domains…too small to entertain 5, like P, possibly Arsenic (lower elements, such as antimony, may act more like metals)
.March 14: aiming for lab tomorrow, report due March 22...proper format...Lab-write! Stoichiometry will be visited/revisited frequently, but we need to move on...VSEPR will commence today...think 3-D and all will be as it needs to be. This should finish the week, and continue into next week. VSEPR will segue into hybrid orbitals (review chapter 8, as needed) and allow you to get a clearer picture of inter-molecular attractions
March 13: some more material to view; not all shown in class (yet?)

March 12: Onward...more stoichiometry, yield calculations, even a simple lab this week. I expect us to enter into the VSEPR zone, and will be obtaining materials for a lab of sorts on this topic. Think of three dimensions and you will find this an in-depth discussion (yes, I had to do that!) I have a number of handouts, some just reading/resource, some with activities. I will be adding Quizlet to our assortment of tools for better learning.
March 08: I will be adding resources to this page, again. I am not happy with the google site interface, but will continue it for students to submit work...I think there will be an announcement for this later today...I have to consult someone so that I provide the correct information for this. Resources, meaning files of documents, powerpoints, websites, will be provided on this page, so all should be checking at least once daily for updates. I will be adding these on top of this document, so that they will be readily apparent.
Your cooperation is expected and appreciated.
