1 Physics – Wed, August 28Find your assigned seat & begin quietly reading Syllabus & Introduction, Materials, Rules, etcPlease tell your teacher if you have a nickname you prefer.Asst a: Multiplying with Significant Figures: columns C&E 1-15 (must show calc answer & then correct sig fig answer only) AND B 1-15 (must be stacked as example shown in class) – due tomorrow, and quiz Fri!Asst b: Information Survey – instructions 1-5As they walk in, I remind them to find their seat, and to start quietly reading their Syllabus.5 minutes after the bell rings, I go over the following with them (in 5-10 min):copying HW :(I actually do mean EXACTLY what that materials list has on it (although I will give them their first red pen) AND it is SRONGLY STRONGLY advised for them to have their binder tomorrow, because I’ll be handing out 400 thingsThat’s the highest percentage of tests they are likely ever to have seen; copying HW won’t help them!Hand-out Sig Fig paper, do #C1 with them with calc on doc cam. Tell them to write calc answer & then correct sig-fig answer. Put in terms of which lab partner didn’t measure good enough, and that’s why we always “guestimate” in between smallest mark on measuring device!Let them work (you wander) until minutes left in class. MAKE THEM STOP, and go on to B1. Tell them its new & they haven’t seen it before! Stack the problem as you see in Kim’s key, lining up decimals. Get calc answer. Cross out insignificant columns from right to left, emphasizing lab partners again. Encourage them to work on this column until end of class.5 minutes ‘till end of class, hand out Information Survey + 1 blank paper per kid.Talk to kids who didn’t have Trig last year - I’ll give you your list. (ie: did they do their HW? How did it go, ask them to bring it tomorrow)
2 Physics – Thurs, August 29Organize Binders – copy today’s agenda!, dividers, handouts, materials (pencils, red pens, highlighters, calculator, protractor & ruler)Introduction to WebpageAnswers to last night’s HW (quickly) - do tomorrow insteadTogether do tonight's asst: #11, then #5aAsst a: worksheet due tom. (there’s a quiz!)FLM (top) = Bolded problems in 3,5,6,7,10;Best-fitting bottom #11-14 (see examples posted on website)Asst b: Information survey – instructions 6-10I have 400 handouts for them today; all things that go in their HANDOUT section; I’ll always make copies for both of us!However, as soon as the bell rings, the FIRST thing you ask them to do is to take out a lined piece of paper, and copy today’s agenda. When they do it, they are allowed to take short-cuts, such as… (it should take no more than 3 minutes)8/291. Organize Binders2. See Webpage3. Start tonight’s asst (or “do #11 and 5a”)5. Asst a: Best-fitting (3,5,6,7,10 bolded) & FLM 11-14Asst b: Information Survey 6-10hand out binder rubric - goes in front of first divider; hand out all other papers that go in “Reference Section”; have them label dividers (by 20 after, at the latest, you should be moving on!)QUICKLY show them the link to the Physics webpage, and how they’ll get hints to tonight’s HW if they need it! (You need to build a link to it in your own moodle page or on the DUSD SchoolWires page :)Do all of #11 with them step-by-step. Tell the non-calc kids to get out & USE best-fitting instructions we handed out earlier.Let them work until 10 minutes before then end of class, and then do #5a with them. Stress they may do Dimensional Analysis any way a previous science teacher has taught them, and it may look different from yours!If you don’t quite finish, remind them to visit the webpage!Collect non-Trig kids HW!
3 Physics – Fri, August 30Don’t forget to copy today’s agenda! You may abbreviate slightly.Go over both HWs (collect! make sure the title & date assigned is on both!)Quiz: FLM & Best-fitting (always use sig figs!!)Asst: Algebra & Trig ReviewAlgebra Review – circled problems on front, except 7,9,27,33,37; 40&45 we’ll do together Tues.Trig Review – 5-23 (on back of Algebra; #15-20 use SOHCAHTOA; #21-23 use sin1, cos1, and tan1)Information survey – instructions (it is due, fully completed, Tuesday)MUST have ruler & protractor Tuesday!Get a graphing calculator too, if you don’t have one, or come talk to me!Remind them to copy the agenda each day for a bit; ultimately they’ll do it automatically, and you’ll NEVER have to deal with absent students! :)I'm going to hand out HW while they're writing the daily agenda/schedule, so they all have it. (that way they can make chicken scratches about the asst on it if they want.)They correct in red pen ...Read off answers to sig figs column C; ask for questions (answer verbally, with them telling you how many sig figs each data point has). Then read off answers to column E, same as C. Finally, read off answers to column B, ask for questions (work out any on the doc cam)Collect the sig fig asst as soon as we finish going over it. (Person in front row sorts into 2 stacks: worksheet & assts - which should each have a title and date assigned on it!)Hand-out keys to FLM & best-fitting (note there’s a mistake on the back of the key!) I pick up the first 2 stacks after I've handed out the keys to FLM & best-fitting, and have them working.By 35 minutes past (at the latest) you should be collecting the last 3 stacks (there's the keys to collect; have them pass them up by row in numerical order.Get them ready for the quiz. I'm going to let them use their own calculator for the quiz (each class has its own version, so its harder to cheat.) They also get to use their best-fit instructions if they need them. ("That damn band camp last year!")**I sort through the keys while they're taking their quiz to make sure I have them all back in numerical order.When they bring you their completed quiz, hand them the HW, which they quietly wok on ‘till the end of the period (or everyone finishes quiz)
4 Tues, Sept 3 Don’t forget to copy today’s agenda! Grade own quiz in red penBrief lecture notes on solving “system of equations”Collect HW & Information Survey (titled & dated)Asst: Start Vectors PacketOn your HOMEWORK paper (not in your binder!), take good notes on pages 1 and 2On that same paper, do example problem that is on page 3On the bottom of page 4, do addition problems P1-P3 and P5-P8 using the vectors (“set 1”) listed to the left.Note answers are listed on the last page!I ALWAYS let them grade their own quizzes, since they’re so few points, and that’s how they learn. I have keys for these already.Recollect so you can record their scores.Lecture notes: I do it as I was taught in college, which is that you skip a line directly after the day’s agenda and write the lecture notes there.Mary used to do them as SHE did in college, which was to have all lecture notes on a separate sheet on paper, in the back of this binder section. We can talk about pros & cons.Whichever system you decide on, I grab a kid’s binder, plop it on the doc cam, and show them what I mean….Do # 40 with them using matrices. Have them write the problem in their notes, then put up your calc and go with them step-by-step through it. Encourage them to write down steps in their notes if they’ve forgotten how to do it.Then have them do #45 with a matrix.Do # 40 with them using the graphing method (intersecting lines) . Have them solve each equation for y in their notes, then put up your calc and go with them step-by-step through it. Encourage them to write down steps in their notes if they’ve forgotten how to do it.Then have them do #45 with intersecting lines.**Remind them we will use BOTH METHODS this year a lot on HW and tests; they won’t be able to get an A if they can’t do it both ways!Give them answer key to rest of alg/trig. Have them pass up all keys10 minutes before end of class, in numerical order. Also collect HW (title & date)5 minutes to end of class: Handout Vectors packet & explain HWYou need a ruler & protractor for these!
5 Systems of equations #40 & 45 matrices & graphing intersecting lines When graphing intersecting lines, solve both equations for y (use parentheses when dividing).Plug into y1 = & y2 = in graphing calculator. Then ...See AP thing I ed you for helpful hints on how to do this stuff :)Now do #45 both ways in your lecture notes!
6 Wed, Sept 4Don’t forget to copy today’s & every day's agenda! Sr’s copy tomorrow’s as well….Work on vectors (day 1 if you didn’t get them all; move on to day 2 if you did)Both assts will be collected tomorrow, stapled togetherVectors Quiz – last 25 minutes of classAsst:vector set 2 w/ graphical method P3-P5, P7-P9(do NOT convert the angles to 0-360, do them in the NWES system!)I give them a big speech about “Are you lost & confused? Well, here’s what you SHOULD have done this weekend, and what you HAVE to learn to do in college…FIND HELP FROM ANOTHER STUDENT”Then I let them hop to it.I’ve got quizzes (and answer keys) somewhere in my file cabinet at school; need to find them …Thursday, Sept 5th, 2013 (Sr Kick Off 2nd-5th)Do problems P1-P9, skip P6 using set 3 & the graphical method.
7 Fri, Sept 6 (rally) Correct quiz 2 (if time) Turn in HW Stapled together in this order: notes, example problem, set 1, set 2, set 3 (Make sure there’s a line separating sets, if you did them on the same page)Lecture notes: component methodAsst: Redo set 1 w/ component method (tonight you may skip #6, #8)#9 started together:Usually takes less than 15 minutes to go over & recollect quizzes. Emphasize any scores below 70% need to get help, as it will be on the unit test!Then about 20 minutes lecture notes. I actually usually use the problem I gave them on the quiz for the lecture notes on the component method.Note that I added the instructions I give the AP kids to the left of the next 2 slides, so its easier to follow along.Then I have them get out their HW paper and we do #9 together. Sometimes they have to finish it at home, sometimes we do finish it in class. Depends on level of class.
8 Component Method (last school year’s notes) From last year, for your reference
9 Component Method continued (last school year’s notes)
10 start #9 together! (2011)From last year for your reference
12 Mon Sept 9 Do self-binder-check in 1st column You can keep your binders in class if you like10-15 minutes for help on component methodQuiz: Component methodAsst: Vectors set 2 with componentsTonight you may skip #6 also, AND #7Donation Letter out (Thurs Back To School night)I actually give them 20 minutes of class time to work on HW, study ask questions, etc.During this time: remind them I grade on completion, and mostly right. I don’t grade on correctness though.BUT, it will show up on their test/quiz results if they are copying the HW and/or not understanding and get the answers correct.The quiz is actually BOTH methods combined! (see next slides)Start at latest by half past.Again, I have keys for them.As soon as they hand you their quiz, I let them quietly start their HW.
13 Tues Sept 10Turn in HW, stapled together: Sets 1 and 2 with componentsGrade quiz in red pen (12+16 = 28 points total … / 10)Vectors Minilab: READ TOP CAREFULLY & follow directions to collect data as precisely and accurately as possibleWork in groups of 3 or 4Change in directions: Only make ONE protractor (set of data) for your whole group to sharePut all names on that protractor, and turn in at end of periodSee “Lecture Notes” on overhead/webpage about equilibriantAsst A: Finish all Analysis questions on minilab (hints will be posted on webpage)Asst B: Get donation letter signed by a parent/guardian; $0 is OK to fill in if times are tough…Asst C 1st & 3rd period: Remind parents Mrs. Lewis will not be at Back To School Night & to me if they have any questions or concernsAll the labs can be found on the webpage.Since Friday is a rally day, we have to rush things!(Notes on equilibrium are on the next slide!)
14 I put these up 20 minutes before end of class, or when first group gets to it. Also posted on webpage.
15 Wed Sept 11 (collab) Go over minilab See next 2 slidesLecture Notes – Speed and Velocity IMPORTANT!!!!!Asst a: Speed/Velocity packet 1-18 (#1 only do to mi/hr, #7 only do Mercury & Earth; start 7 & 11 together) – hints on website!DONATION letters?No skirts/dresses tomorrow; wear good shoes!Again, I have keys for the quizzes.See next 4 slides for last year’s discussion of minilab & the lecture notes.Also #7 and #11 are started on the 5th next slide.I need to figure out the HW this week to abide by HW policy.UNIT TEST Friday the 20th!!!!!
16 Vectors Lab3) so, according to above, your answer should be pretty close to the opposite of vector C (in other words -C)5) the equilibriant (purple ray) is equal and opposite to the resultant (blue ray); so equil(A+B)=CIf the equilibriant is asked for, find the resultant and flip the direction!6) only use the MAGNITUDES to do the % error8) equil (B + C) = A; 9) B + C = -A11) C + A = -B; equil(C + A) = B
17 There are 3 or 4 questions on the minilab that they need to understand There are 3 or 4 questions on the minilab that they need to understand. Those are the one at the top of this slide (not highlighted.)The highlighted problem is a little self-quiz I have them do on the bottom of the lab - a “check for understanding”
18 Get a red pen, we’ll go over the quiz…. After we correct it, how would you find the equilibriant of the problem?Note: If you did not do well, you MUST come in for help! We are mostly done working on vectors in class, but they are 40% of the first unit test!
19 Lecture notes: Distance, Displacement, Speed & Velocity Copy the figure belowA = 3 km East, B = 4 km NorthElephant walked A+B in 2 hoursThe distance is the total path walked (a scalar)What is this?The displacement (a vector) is the straight difference between the start point and the end point “as the crow flies”
20 Lecture notes: Distance, Displacement, Speed & Velocity The elephant walked A+B in 2 hoursThe speed is defined to be distance / timeWhat is this?THIS IS A SCALARThe velocity is defined to be the displacement / timeTHIS IS A VECTOR, so don't forget direction!!!!These 4 questions about the elephant are question #2 on your first unit test, but with a more complicated vector problem than A+B in hor/vert directions!
21 Lecture notes: Distance, Displacement, Speed & Velocity If speed = distance / time, let’s review some simple algebra…What is distance = ?What is time = ?BE CAREFUL! CROSS-MULTIPLY!
22 Lecture notes: Distance, Displacement, Speed & Velocity Question #1 on your first unit test asks for the definitions of distance vs displacement; and the formulas for speed & velocityIt also asks which are scalars & which are vectorsAnd is asks the following to make sure you get it … (see next slide)
23 A bumblebee flew 56 meters along a long, twisting path only to land on a flower 1.0 meter due east of the point from which it started. If the entire trip took 30 minutes, what was its distance, displacement, average speed and average velocity?One of my favorite examples, similar to what they see in their HW, and one they may use on their unit test if they choose. (I even suggest that!)
24 Let’s start #7 and #11 together 7) Calculate the average speeds in km/yr of Mercury (and Earth, Saturn, and Pluto) in orbit around the sun. Use your astronomical data handout to obtain their "mean distance from the sun" (the radius of the assumed circular orbit) and their "period of revolution" (the time it takes them to go around once).THINK CIRCUMFERENCE!(a) At exactly 1:00PM a car traveling WEST at a constant speed of 24 km/hr is 11 km WEST of the school. Where will the car be at 3:30PM? (b) If instead the car was 11 km EAST of the school at 1:00PM, but still traveling WEST at a constant speed of 24 km/hr, where will the car be at 3:30PM?DRAW A GOOD ANNOTATED PICTURE!
26 Old lecture notesIf I have time I’ll change this into a more formal slide that has prompts.If I don’t get to that, you can just print this out & reproduce it yourself with the tablet pen.They need to know all this for question 1 of their unit test; I actually tell them that too!
27 More old lecture notesBelieve it or not, even these kids need a little algebraic reminder from time to time, especially the first few days of school!
28 Thurs September 12 (Back to School Night – I wont be here) Questions on HW?? (2 from this set are on the test)Talk about tonight's HW – “average speed” & “average velocity”“Human locomotion” minilabAsst: speed & velocity problems 19-34hints on website!DONATION letters?Get ready for a Binder Check! (If you didn’t last week, do a binder self-check quickly in the first column of the rubric! Do you have the agenda copied for every day so far?)Notes are on next slide.This is pretty much the same lab we do in CP; the kids like it!UNIT TEST Friday the 20th!!!!!
30 Human Locomotion Minilab: Method ofLocomotion(10 types total)Distance: (m)Time:(s)Average Speed:(m/s)Rank:I make them write a “results & Conclusion” for almost everything.Results & Conclusions: (has 4 parts: restate purpose, state results, error analysis, application of experiment)The purpose of this experiment was to prove that the fastest (non-mechanical) way to move a human body 10.0 meters is by crab-walking. The experiment proved that …. Possible sources of error were …. An application of this experiment is …
31 Fri Sept 13 Go over HW (3 from this set are on the test) “The Optimal Average Speed of Collapse of a Domino Column” – get DATAAsst: Speed/Velocity packet skip 39 (continue to look on website and/or me for help/hints)** All will be collected tomorrow (Monday)DONATION letters - LAST DAY for HW credit (even if with a zero donation)!This is a fun but crazy lab!UNIT TEST Friday the 20th!!!!!
32 The Optimal Average Speed of Collapse of a Domino Column Purpose:The purpose of this experiment is to determine the optimal (best) separation between dominoes lined up in a column, so that a specific column length of dominoes will collapse the most quickly.
33 The Optimal … of a Domino … Day 2Step 1) Do your graph of speed (list 2 on the y axis) vs separation (list 1 on the x axis). Sketch the graph on your lab paper. Use 2nd calc to find the maximum of the graph and write it on your paper too. Bring me your calculator with the max shown on the graph in the window. I will stamp it, and then you must erase your data & equation.Step 2) Write your R&C ….Results & Conclusions: (has 4 parts: restate purpose, state results, error analysis, application of experiment)The purpose of this experiment was to determine the optimal separation between dominoes lined up in a column, so that a specific column length of dominoes will collapse the most quickly. The experiment determined that the best domino separation would be ____ cm, which would fall with a speed of ____ m/s. Possible sources of error were …. An application of this experiment is …
34 Mon Sept 16 UNIT TEST Friday the 20th!!!!! Go over HW (2 from this set are on the test); turn inFinish & turn in Human Locomotion lab if didn’tFinish & turn in “Optimal Average Speed ... Domino...”Collect rest of data if neededDo graph, best-fit quadratic, find max; get my signature/stamp on the sketch of graph on your paperDo R&CBOOKS OUT!Put your name in your book & take it home!Pass out HW – YOU MUST MEASURE IN BETWEEN THE DASHES on your ruler; ie to the hundredth of a cm (or the 10th of a mm)!Start “Average Speed” experiment parts a-b (You MUST have data and a speed by tomorrow. Acceptable speeds are listed. Check yours, and me if you don’t have that!)On the BACK, part B #5 should say 35 mm measured = x 108 meters actualMostly a catch-up day for everything.I will probably make a printout of this & the next 2 days schedules, since kids will be gone, we’ll be in the lab, things will be crazy.UNIT TEST Friday the 20th!!!!!
35 Tues Sept 17Binder check ?? … Friday ?? You MUST have your own ruler & protractor! Do you have all the daily agendas?Math Computer Lab: data & start first write-up togetherAsst:See ½-sheet Handout for book work plus re-do these … #31,35,48 in the speed packet (note that every question we assign the next few days IS ON THE TEST!)Print off the Study Guide!! (it MUST be in your binder Wed!)If you missed more than 5 on the last quiz, you must do this one on a separate sheet of paper: Vector packet using set 1, do 3B-C w/ both graphical & component methods; answers in both NWES and 0-360We take the classes to a computer lab for the next 2 days.We do the data in excel using formulas, etc.I have a couple of handouts to give you that are helpful.UNIT TEST Friday the 20th!!!!!

COME AS EARLY AS YOU CAN TO GET STARTED!!!Binder check: Do you have your own protractor & ruler? Do you have the study guide printed off? Do you have 17 schedules/agendas (and accompanying lecture notes when given)?
39 NOTE:Physics test policy: If you are absent for more than 1 unit test, you will be given a full essay test as a make-up.If you are absent for only the test period, our “reasonable time period” is an hour for an hour, so the test will have to be taken within an hour of the period you missed. If you are absent for the whole day, you must take it the next day after school, since it’s a day for a day. (See above about being absent for more than 1 test!)Any school field trips or sporting events: the policy clearly states that the test must be taken BEFORE the absence.
40 IF WE DO NOT HAVE TIME TO GO OVER ALL OF THIS (Collaboration Day), IT IS YOUR RESPONSIBILTY TO LOOK IT OVER AT HOME, AND US TONIGHT IF YOU HAVE QUESTIONS!!!!!They should have their own printout of this.I have them read it and ask questions.
42 Fri Sept 20th This is the last agenda printed on your handout for you… Turn in notebooks - CHANGED TO FRIDAYMake sure you have everything in your reference sectionMake sure all assts are in chronological orderMakes sure nothing is in your pocketsUNIT TEST!You will need your ruler & protractorI will provide you with a calculator; PUT IS IN DEGREES!Cell phones in backpacks; both hands on desk at all timesAsst: Packet notes up to & including page 76 “Problem-solving strategy” (Write page numbers, as before!)
