Week of 11/17

 Monday: Today we reviewed for test. Here’s the notes from today and other days. Here’s some notes from last year that are somewhat more organized. Test  tomorrow.

Tuesday: Test

Wednesday:  PhET simulation for collision theory. Maxwell Boltzmann Distribution lesson.  Here’s a link to my lecture! Class worksheet.  HW: Read hand out regarding effusion and diffusion and answer questions.

Thursday: Notes on collision theory and potential energy diagrams WS. HW: read about catalytic convertor. Video on catalytic converter.  A movie to explain today’s concepts.  Another movie that mixes Maxwell Boltzmann and the PE diagram.

Friday:  we started with CA 36 to learn how to calculate reaction rates and use stoichiometry to get reaction rate of one product or reactant when another is known.  Then we went over a graph of concentration vs. time and explained the shape. Next we used this animation thing to show what is meant by instantaneous rate.  Lastly I lectured on how to determine the rate law.  Here’s the notes (after collision theory) + these powerpoint notes.  A video for today’s lesson. We did a quick practice question with a reaction rate graph and then went over how to figure out units for rate constants. The rest of class we worked on CA 57.  Here’s the answer key.

 

Week of 11/10

Monday: Today we started with notes on real vs. ideal gases. The take-away is that real gases experience electrostatic attractions and their volume is not insignificant. Most gases are ideal under low pressure (normal atmospheric conditions), but become real under really high pressures.  The rest of class we worked on designing the ideal gas constant lab.  You worked in groups of 6 to plan, but will split in to 3’s when you do the experiment. I gave opportunities to do the experiment so you could work out some of the kinks.

Tuesday: Veteran’s day. no school!

Wednesday: you guys did the lab.

Thursday: we went over redox test for most of the class.  I reiterated that you need to be reading the textbook, that you need to be really learning from your labs/ understand what is going on/ be able to do the calculations on your own.

Friday: I will be late and will perhaps miss class altogether. You will have time to do calculations and type conclusion. Please turn in typed conclusion w/ picture of data notebook pages into google classroom by Wednesday next week. Data notebook should include everything that is on the data notebook section of the checklist.  Data may be printed from your google doc and pasted in (I want to be able to reference your data values easily when grading your calculations).  You only need to show one sample calculation for your calculation of #, but need to show all the results and the average.

AP Gas Law Problems Answers  also available in video  form: Part 1  Part 2

Week of 11/3

Monday: Test on redox reactions, Review gas laws on your own by reading textbook ch. 5 sections 1-3, pages 176-196 or review videos under unit 3. Do Textbook problems 5.39 to 5.49 odd only, 5.63 and 5.67 , 5.69, 5.71.  For using ideal gas law to calculate density or molar mass see examples on p 189-192.

Tuesday: Teacher work day

Wednesday: You guys went and got computer to get the simulation up and running. While waiting you worked on 5.27 and 5.28.  in the middle of that I defined pressure and went over KMT postulates.  The newest detail being determining speed of differently sized molecules. I gave 5 more min to do the book problems and then did the gas demos.  At 10:10 we started the  Gas laws simulation lab.  HW: See unit outline.

Thursday: worked on sim.  Please turn in ASAP.

Friday: Today we started with are view of scientific notation as a help in solving mental math problems.  I went over the idea that for stoichiometry problems involving gases reacting to form gases, you can treat the volumes like moles. Then you had awhile to work on the multiple choice problems in the packet.  Next I lectured on dalton’s law and the idea of collecting gas over water.  We did some more problems in the packet.  Then I introduced the mole fraction and partial pressure equations.  The rest of class you had to work on homework.  Here’s the notes.
