Week 36 - 6/1 to 6/5
For our last week of class, I'm reposting last week's materials and adding one final major assignment - a virtual titration lab which is due Wed 6/3. It is posted below under the new weekly goals. Remember that all assignments you wish to have graded need to be posted to the Quarter 4 tracker by 11:59 pm on Fri 6/5. Our last socrative quiz will take place on Thurs 6/4 or Fri 6/5 during the regularly scheduled orange/blue class period. The make-up for this last quiz will be at 1:00 on Mon 6/8. Please email me if you have an issue. Continue using all of the resources available to master chapter 15 & 16 and I hope see you at tutoring on Tues and Wed this week at 1:00. Remember, the final exam is optional. It's a really hard time for so many people right now. If you need help, I'm here. Please don't be afraid to reach out.
INFO ON CPS GRADING UPDATE -
Now that we are certain we are not going to return to school this semester, CPS has changed the way in which final report card grades will be determined. The basic intent of the original policy remains the same, but there is a provision to address students that do not participate meaningfully in remote learning during 4th quarter.

The basic intent of the original policy remains the same, but there is a provision to address students that do not participate meaningfully in remote learning during 4th quarter.
- If you fail 4th quarter, your GPA will not be impacted, but you will receive an "INC" (for incomplete) on your report card and need to retake 2nd semester chemistry in order to graduate.
- If you pass 4th quarter, but with a grade lower than that you received in 3rd quarter, it will not impact your GPA and you will receive a "P" (for passing) on your report card.
- If you pass 4th quarter with a grade equal to or higher than your 3rd quarter grade, you will see a regular letter grade on your report card and it will count in your GPA.
- I realize it is going to be harder for some students to adjust than others. I am truly mostly concerned with your physical and emotional health, so whenever you are unable to complete something - just email me. If you let me know what's going on, I can help you, for real. I am going to be very understanding about deadlines, IF you reach out and communicate with me. However, if you don't do your work and do not communicate, we will have a problem. I sincerely want to avoid giving a single student an INC this semester, so PLEASE stay in touch! I love you, miss you and wish like crazy that we could just be back in school, but this is the best we can manage right now & we'll get through it together..
Calendar of Due Dates - Plan ahead & remember to email me with any questions about anything :) Focus on the major assignment each week & the Thurs/Friday Socrative quiz. Last day to post assignments is Fri 6/5.
Chapter 15 & 16 "I CANs"...
...define and identify the solute and solvent in a given solution.
...calculate molarities of various solutions and quantitatively determine how they were prepared. M=mol/L
...determine how to prepare dilute solutions from standard solutions using the dilution equation. M1V1 = M2V2
... define and identify Arrhenius and Bornsted-Lowry acids and bases.
...calculate Kw, pH, pOH, [H3O+] & [OH-] of various solutions and use them to describe the relative acidity or basicity of the solution. Kw =[H3O+] x [OH-], pH = -log[H3O+] , pOH = -log[OH-]
... analyze titration data to determine the unknown concentration of an acidic or basic solution. (next week)

This Week's Goals -
Complete the new virtual titration lab for our last major assignment and prepare for our ch 15 & 16 socrative quiz on Thurs 6/4 or Fri 6/5 during regularly scheduled orange/blue class periods. The only makeup for this quiz will be on Mon 6/8 at 1pm. Email me immediately if you have a conflict.
You may also use this week to post any old work you would like me to grade to the quarter 4 assignment tracker. If it is an assignment which I have already finished grading and entered into Aspen, please drop me an email to let me know it's been posted (not necessary if I haven't entered the grades for that assignment in Aspen already).
- NEW (and last) MAJOR ASSIGNMENT - Virtual Titration Lab (link). This lab is the best one I could find, but it is British, so there will be a few minor vocabulary differences and they present the algebraic calculations in a slightly different manner than we're used to seeing in our class. Therefore, it will be graded as a completion assignment. I won't enter your score on the lab, but you must complete the simulation to earn full credit. Important info and tips are as follows...
- When you click on the link, you will need to register. The site will assign you a number that you can use to log back in if you need to stop before completing the whole activity. Be sure not to lose that number in case you need to stop and take a break from the simulation for some reason. It took me about 25 minutes to finish the activity, but I already know how to titrate and you're just learning, so give yourself more time than that :)
- I am only requiring that you do Titration Level 1. The other more advanced titrations are fun too, but totally optional and will not earn any extra credit.
- As with last week's Labster simulations, you will need to post a selfie of yourself with the completion screen for the Level 1 titration visible on your computer to the quarter 4 Assignment tracker (link)
- If you run into any technical difficulties, just email me and we can work something out.
- Review videos & prepare for socrative Chapter 15/16 Solutions & Acid/Base Quiz at the end of this week during regularly scheduled class periods on 6/4 & 6/5. ORANGE = Thurs & BLUE = Fri.
- Review Ch 15 - Solutions Slides Presentation (link)
- Review Ch 16 - Acids/Bases Slides Presentation (link)
- Consider using the Chapter 15/16 - Greatest Hits of Student Questions (link) and Virtual Parking Lot (link) - Let me know what you'd like me to teach about in the live tutoring sessions!
- Decide if you're planning on taking the comprehensive semester 2 final exam (chapters 6,7,8,9,10,13,14,15,& 16). I'll be sending out a survey next weekend to see who plans on participating. Final exam scores will be entered into the "Exams" category, not the "Online Learning" category. The intent is to offer those who wish to elevate their grade an opportunity to do so by demonstrating a full understanding of this semester's learning. For this reason, the testing procedures will need to be more secure than the quizzes have turned out to be.
Last Week's Goals - reposting in case you didn't finish them
The two Labster virtual labs (Solution Preparation and Acids & Bases - Principles) were due on Fri 5/29 and the ungraded bookwork should be completed by Mon 6/1.
- MAJOR ASSIGNMENTS - We're using a new platform this week called Labster to do two different virtual labs. Post a link to the Quarter 4 Assignment Tracker When you click on the link, you will need to select "login with Google" and use your CPS email address to access the labs. You'll probably get the hang of how the program works with a few minutes of trial and error, but you need to click on the right things at the right times to complete the lab. There's a "lab pad" that has instructions AND information the lab topics on one of its other tabs. Be sure to check it out. Unfortunately, what our book calls M (molarity), Labster abbreviates with a C for concentration. Like us, it uses n to abbreviate mols, but in their lingo M stands for molar mass. If you run into trouble, use the Ch 15/16 Greatest Hits of Students Questions (link) to ask for help. We can all answer each other's questions there so you don't necessarily have to wait for me to see you email if you're stuck. Chances are someone else has gotten stuck there too, but then figured it out. I will check this help google doc several times a day and respond also.

Socrative Quiz Info...our last quiz will be this week on 6/4 & 6/5 during regularly scheduled orange-blue class periods. The make-up time for this Ch 15/16 quiz is Mon 6/8 at 1pm. Please email me immediately if you have a conflict.
Log into socrative.com and join the room for your class period. I've separated the class periods out into five rooms: TRINE1, TRINE2, TRINE4, TRINE5 & TRINE 7. If you did not take the chapter 7/8 exam &/or the chapter 9 exam &/or the chapter 13 Gas Quiz A, please consider doing so. You can always take them. They are waiting in their own socrative rooms called "CH78TRINE" & "CH9TRINE" & "CH13ATRINE". IF YOU MISSED CH 10 QUIZ, THE RETAKE IS ON MONDAY 5/18 at 1:00 pm.
- try your hardest
- use your study materials like you will when you take an optional final exam (keep them organized!)
- learn from it
- realize it's not as good or thorough as our normal tests
- EMAIL MRS. TRINE ASAP IF YOU CAN'T TAKE THE SOCRATIVE QUIZZES ON TIME!
