  • AP Mock Exam Saturday March 23rd

    Please plan to arrive by 8:00 am.  I am currently planning to administer the mock exam here in my room, C104.  Extra credit will be offered to all students who participate in this event!  As previously offered, I will treat my AP students to snacks/food at Room 251 in the event that we obtain at least one '3' and one '2'.  Please bring your favored calculator for the Free Response Questions.

  • Cycle 7 Shoptime AP Chemistry

    Our next unit is "Bonding and Periodic Trends".  Shoptime is Flinnprep units 4 and 15.  Unit 4 is just review of Lewis and VSEPR, should be easy.  Unit 15 is an AP-level unit about analysis of chemicals by spectroscopy - we may be able to tie this into some of the Honors projects going on this year.

    Textbook reading is the "Tools of the Laboratory: Mass Spectrometry" in Chapter 2 section 5, Chapter 8 sections 2 and 3, Chapter 9 sections 2, 3, and 6, Chapter 10 section 1 on 'Formal Charge'. 

    One more cycle to go!  Congratulations on all your hard work so far.

  • Cycle 6 Shoptime AP Chemistry

    Our next unit is a double, 'Gases and Intermolecular Forces'.  Shoptime assignment is FlinnPrep unit 7, "gases", and FlinnPrep unit 5, "structure and properties".  These are both honors-level units so should not be a major challenge, but you need to know them very well.  As usual, please don't wait until 2:00 am on Monday morning.

    Textbook reading for this unit should be 5.2, 5.3, 5.4, 5.5 on gases, as well as 12.3 on types of intermolecular forces.

    Lab Writeup:  Please write a report about your titration of unknown.  You may use the plot we prepared together.  Please submit this online using Google Docs share.  Please answer the following questions.  Provide justifications, explanations, and calculations as necessary.

    • Is your unknown an acid or is it a base?
    • Is your unknown weak/strong?
    • What is the concentration of your unknown?
    • What is the chemical formula/identity of your unknown, and how do you know this?

  • Cycle 5 Shoptime AP Chemistry

    Our next unit is on acids and bases.  The Flinnprep unit for this is Unit 9, "Acids and Bases".  The good news is, this FlinnPrep is basically Honors stuff, we can save the real AP stuff for actual class time.  What you have already learned about equilibrium and equilibrium constant K will come in very handy for this upcoming unit.  The bad news is that logarithms are back again.  While we have mostly used natural logarithms (base e) for our thermodynamics and kinetics units, the next unit mostly uses 10-based logarithms or 'common logarithms', symbolized as log10() or simply log().

    You've probably heard about pH.  The 'H' is just the molar concentration of hydrogen ion, [H+] or sometimes [H3O+].  Authors often write H3O+ to represent that the H+ ion is generally stuck to a water molecule in solution.  But what does 'p' mean?  'p' means the negative of the 10-based logarithm.  'p' is short for -log10().  So pH is just -log10([H+]).  You may need to use logarithms combined with reaction quotients and equilibrium constants in this unit.  Study logarithms!

    You might also recall the list of 'strong acids' from the net ionic equations lesson in cycle 1:  these are 'strong electrolytes' that completely disassociate in solution.  They are HCl, HBr, HI, HNO3, H2SO4, HClO4, and maybe the unstable and rare HClO3.  Names are hydrochloric acid, hydrobromic acid, hydroiodic acid, nitric acid, sulfuric acid, perchloric acid, and the rare unstable chloric acid.  Memorize them, seriously, AP expects you to.

    Reading for the cycle is Chapter 18 Sections 18.1, 18.2, 18.3, 18.4, 18.6, 18.7.

  • Cycle 4 Shoptime AP Chemistry

    The Flinnprep unit for this is Unit 13, "Kinetics". I warn you that logarithms (particularly the natural logarithm function "ln") will be involved.  If you need to, please review logarithms on Khan Academy or another source of your choice, or come see me over your shop cycle for logarithm help, or talk to your math teacher.  As before, I'd like people to have 100% or close before they return on unit 13, so do your first attempt at the halfway point of the shop cycle.  That way, I can actually email you feedback - and I will!  The program itself will also provide feedback.  I will not give full credit for a last-minute attempt, unless of course it's 100%.

    Reading for the cycle is Chapter 16 Sections 16.1, 16.2, 16.3, 16.4, 16.6, and 16.7.  This will help you with the FlinnPrep as well as with the material in Cycle 5.

    Have a joyous holiday season, and study hard!

  • Cycle 3 Shoptime AP Chemistry

    The Flinnprep unit for this is Unit 11, "Thermochemistry".  This is a difficult unit and you should know it well before returning, as this is the last really huge cycle ahead of us.  I basically want everybody to have 100% on this one before they return.  So do your first attempt at the assessment by the halfway point of the shop cycle.  For A week, this is Monday the 19th (Veterans Day).  This way, I can actually email you feedback - and I will!  You will also get feedback from the FlinnPrep program itself.  There is no reason not to shoot for 100% and you really should go for 100%.  As this is the only unit for this shoptime, I will probably count it as double.  Do well.  I will not give full credit for a last-minute attempt, unless it's 100% that is.  100% is always a good grade.  

    Unit 11 does not cover the entire contents of Cycle 4, but it gives us a good head start and we will need it.

    Reading for the cycle is Chapter 6 sections 1-6 (some of those sections are pretty short) and Chapter 20 Sections 1-3.  It's a lot, I'm not going to say it isn't.  But if you do a little bit every day of the shop cycle, and use the book as a resource to help you through the FlinnPrep, we'll be ready to tackle difficult material.

  • Cycle 2 Shoptime AP Chemistry

    Your assignment is to complete Flinnprep units #8 and #12. This is a graded activity.  You should be aiming for a score of 80% or higher to receive full credit, and may redo the unit as many times as necessary.  Please contact me if you have any difficulties.  These units are estimated by Flinn to take approximately 60 minutes and 80 minutes each, but this is assuming a full 2 semesters of Honors Chemistry taken prior to AP Chemistry, which we have not taken.  Therefore, they may take longer.  Please note that the online units have links to helpful resources at the bottom.  You may also use the textbook as a reference.  Please budget adequate time to work on these.  Do not wait until Sunday before we return to class, as you will have no time to contact me for assistance or to consult your textbook or other resources.  

    You should also begin reading for the next cycle.  The textbook sections for the next cycle are Chapter 17, sections 17.1, 17.2, 17.4, 17.5, 17.6, and Chapter 19 section 19.3

    There may be a 'pop quiz' based on the textbook reading and/or the FlinnPrep material upon your return.

    Please contact me by email with any questions or difficulties.  Feel free to visit as well, as your schedule permits.

  • Cycle 1 Shoptime AP Chemistry

    Your assignment is to complete Flinnprep units #3 and #14. This is a graded activity.  You should be aiming for a score of 80% or higher, and may redo the unit as many times as necessary.  Please contact me if you have any difficulties.  These units are estimated by Flinn to take approximately 55 minutes and 85 minutes each, but this is assuming a full 2 semesters of Honors Chemistry taken prior to AP Chemistry, which we have not taken.  Therefore, they may take longer.  Please budget adequate time to work on these.  Please note that the online units have links to helpful resources at the bottom.  You may also use the textbook reading for Cycle 2 as a reference:  Chapter 4 section 5 and Chapter 21 sections 1-3.

    You should also make sure you have read the appropriate textbook sections (Silberberg and Amateis) from this past unit:  Chapter 3 sections 1-4 and Chapter 4 sections 1-3.  This will allow you to consolidate what you have learned.

    You should also begin reading for the next cycle.  As mentioned before, this will be Silberberg Chapter 4 section 5, along with Chapter 21 sections 1-3.

    There may be a 'pop quiz' based on the textbook reading and/or the FlinnPrep material upon your return.

    Please contact me by email with any questions or difficulties.  Feel free to visit as well, as your schedule permits.
