	Monday, September 26	Tuesday, September 27	Wednesday, September 28	Thursday, September 29	Friday, September 30
class	lab day	lab day	we'll use half the class for lab; this is our last lab day; you will want to be finished with the lab by the end of the week (since the electrostatics effects/results have not been spectacular, we will try to shorten some of the lab parts)
reading (always done before class)	up through investigation A of lab D1 (might you also want to page through chapter 28 and read a few sections about diffraction gratings, spectroscopes, CDs, etc ?)	through end of part C of the electrostatics lab D1	pp. 609 - 616 through part D of lab D1	finish section 19(3), paying special attention to the superposition examples	19(4), up to superposition at the top of p.624
in-class presentation	none		bring a table (on a piece of paper that will be handed in) comparing Newton's gravity law and Coulomb's electrostatic law as to: 1) name and number of the type of "charges" that the force involves 2) the rule about how these charges interact: what do likes do? what do opposites do? 3) how the force varies with distance 4) how the force depends on the "charges" involved 5) the meaning of the constant involved in the force 6) what you do if more than 2 charges are involved		19(17)
written homework (by 5 pm)	1) for the sound experiment we did last friday in class (beats in space), the speakers were 0.8 meter apart; the frequency of the sound was 1000 Hz; calculate the angles of all the constructive interference lines that existed in the room (remember the formula we almost derived in class: Walker eq. 28-1) 2) for the light experiment that we did on the overhead (with the diffraction grating), the distance between the slits (i.e., the light sources that interfered to make the spectrum of the screen) was 0.00133 mm (so close that you couldn't see them); I estimated that the angle for the n = 1 constructive interference of the inner violet edge of the spectrum to be 18 degrees; the angle for the n = 1 constructive interference of the outside red edge of the spectrum was 33 degrees. Find the range of visible light wavelengths in nanometers. (and remember that the CI formula for multiple sources -- Walker eq. 28-16 -- is the same as for double sources)		8(16) & 8(18 for spring compressions of 0.020 m and 0.040m) no calculus on spring problems UNLESS ...		19(58)
lab	finally, lab D1 starts bring GREEN lab book	lab D1 continues	lab D1 continues find an hour to finish up the lab with your partner		have you finished lab D1? (monday is the deadline; we start putting equipment away Tuesday); lab quiz on wednesday it does not appear that parts F2 and F3 of the lab are working properly (due to continuing humidity problems); however, part F1 should work, and you should be able to draw a nice diagram in your book to explain what happens

	Monday, September 19	Tuesday, September 20	Wednesday, September 21	Thursday, September 22	Friday, September 23
class			first test	musical instruments day -- bring a musical instrument fill in boxes of the part 8 table COLUMN 1 ONLY in your C6 lab book before coming to class
reading (always done before class)	have you read all of chapter 14 (except for sections 5,6)?	section 14(5) learn about the inverse square law and the decibel scale		review reading on inverse square law and decibels: questions to know the answer to before coming to class: a) if you move 10x farther away from a light source, how intense does the light seem to be compared to initially? b) in what way is the decibel scale like the musical scale you investigated in part 5 of the sound&music lab? what other scales that you know about work in this way?	read section 14(7): know the definitions of destructive and constructive interference and conditions under which they occur look at the two examples and understand the physics and math electrostatics lab postponed till monday because of humidity issues
in-class presentation	14(59ab)
written homework (by 5 pm)	14(63,64)
lab	last friday was the last C6 lab day... plan with your partner when you will finish up last time for lab C6 checks is after school up through 5:30 (when I leave)			electrostatics lab postponed till friday	electrostatics postponed till monday
other	have you returned your C2 spring ? (flesh springs CK are missing from block C; gray spring J is missing from block D)	one of your (many) practice problems posted on the bulletin board by 5 pm today			have your told your parents to look at the course expectations link above if they are coming to parents day? you also might want to print them a copy and give it to them before they come to class on saturday

	Monday, September 12	Tuesday, September 13	Wednesday, September 14	Thursday, September 15	Friday, September 16
class	finish up thursday's 2 vibrator ratio problems		read course expectations (link above) lab = shoes finish up first two parts of the lab before class	read course expectations (link above) lab = shoes complete part 3 (addition of cosines for frequencies of 14 and 18) in your lab book before class complete parts 4 and 5 (data collection only) before class today	read course expectations (link above) lab = shoes come with everything up to and including part 5 finished (checks for these parts only occur at the beginning of the period) i strongly suggest that you also have 1 of the speed of sound measurments & calculations in part 6 completed (musical instruments delayed until monday) test coming next wednesday
reading (always done before class)	14(3-4) read about how a microphone picks up sound how speakers work	read lab C6, parts 1 and 2	1) text, 14(9) 2) lab C6, parts (3,4)	read 1) text, 14(8) & 2) lab C6, parts (6)	read lab C6, part 7
in-class presentation (show and tell)	14(58)		none		none
written homework (by 5 pm)	14(61,82)		14(11a,c & 12)		14(70-71)
lab		labs C3/C4 due by 5 pm start lab C6	continue lab C6	continue lab C6	continue lab C6

	Monday, September 5	Tuesday, September 6	Wednesday, September 7	Thursday, September 8	Friday, September 9
class	labor day; students return	remember to bring your lab book to class TODAY	bring lab book		prelab for lab C4 in your BLUE lab book completed before class
reading (always done before class)		none	14(1,2) + first 2 pages of 14(7)	14(8) through bottom of p. 445
in-class presentation			superposition of waves both exercises 1 and 2 brought to class on paper; it will be graded in class and turned in (so complete it on separate paper)		none, because you are doing the prelab
written homework (by 5 pm)					14(5,9)
lab		we start lab C3	lab C3 continues don't wear your best clothes; you might have to be on the floor "lab shoes" necessary		lab C4 "lab shoes" necessary + gloves or a non-important sock finish lab C3 (including writing a conclusion and be ready to hand it in)
