  1. Mon Jan 27 START SCHEDULES ON A NEW BLANK SHEET OF PAPER!! • New seating chart?? • Binders – • START SCHEDULES ON A NEW BLANK SHEET OF PAPER!! • You MAY take the first semester schedules & assts out, bundle them together, and put them someplace safe at home. (You’ll want them to study for the 2nd semester final) OR … buy a new binder & keep all handouts/reference • Turn in Guided Notes ?? • Slinky Minilab … • Work in groups of 3 (not 4) on the ground in the aisles, • each person fill out worksheet; need to get up to #17 done today • Hand slinky to teacher at end of class to check its not twisted together • Asst: (note there is an enlargement of the first slide on the back!) • packet 1 NOTES and then draw a line and … • ANSWER the self-check questions (number them if they are not #’d; there are 10 of them) • YOU WILL NOT GET FULL CREDIT UNLESS YOU DO BOTH!

  2. Tues Jan 28 • Collect packet 1 work (questions first) • Did you do BOTH notes, drew a line, THEN answered questions too? • You will not get full credit unless you did both • Waves packet 1 quiz • FINISH Slinky minilab – • all of side 2 AND • the interpretation questions must be done • HW: • waves packet 2brief NOTES, draw line, then.. • … ANSWER 18 questions also • (Slinky Minilab with interpretation questions *online if you need them* is due Friday) (oopsie: #16 answer = 5.9E-7 not E-9!)

  3. Slinky Mini-lab Interpretation Questions • What are some major & important characteristics of waves that you have investigated in this minilab? List at least 3. • Where in the environment can you observe properties of waves in action? • The “wave equation” is v = . (Your book says v =  f, but you should learn the use the “nu” which stands for “frequency”. Look at your results for lab questions about speed, wavelength and frequency. Find at least 2 examples which show the relationships in this formula. (ie: if velocity goes up, frequency also goes up, etc.) Write the lab question number, and write out the relationship that question showed, that supports the wave equation. You need at least 2 examples. • Sketch the three wave scenarios on the right on your own paper. After the equals sign, draw a single pulse that has the correct amplitude of that split-second meeting. (Why don’t you write in the value of the amplitude also, so it’s clear.) • ALSO, for each of the three wave scenarios at right, sketch what they will look like AFTER they are done interacting. (Hint: waves pass through and go back to exactly the way they were before, albeit in a new location.) • Finally, for each of the three scenarios at right, tell whether they are constructive or destructive interference.

  4. Wed Jan 29 • Pick 1 partner; 1 of you login to a laptop immediately • Collect packet 2 work (questions first – math??) • Correct quiz 1, Waves packet 2 quiz • Computers: start “CPU’s” • HW (a): waves packet 3 brief NOTES, draw line, then ANSWER questions (# them; there are 16 today) …..DUE tomorrow! • HW (b): Slinky Minilab with interpretation questions *online if you need them* is …..DUE Friday! • HW (c): Start Earthquake packet notes …..DUE Monday! • NOTE that you WILL be able to use anything from your Earthquake notes to answer the Earthquake questions on your waves test! (so do a good job!)

  5. Thursday Jan 30 • 1 partner logs in immediately • Turn in packet 3 work (questions first? – math??) • (can you do those MATHproblems correctly from both packets 2 & 3?) • Correct quiz 2; Waves packet 3 quiz • Computers: CPU’s • remember – you should have Doc 1 already saved in your I drive, so open that & keep going • HW (a): waves packet 4 VERY GOOD NOTES and then ANSWER the four questions ....DUE tomorrow! • HW (b): Slinky Minilab with interpretation questions *online if you need them* is …..DUE tomorrow! • HW (c): Start Earthquake packet notes …..DUE Monday! • NOTE that you WILL be able to use anything from your Earthquake notes to answer the Earthquake questions on your waves test! (so do a good job!) Note, on slide 11, your packet #4 may say: • Question: Open up your Physics book to page 304, Applying Concepts #6.Please scratch that out and replace it with this: • Question: Open up your Physics book to page 397 #68.

  6. Friday Jan 31 • 1 partner logs in immediately • Turn in Slinky Lab • Turn in packet 4 work (questions first?) • (can you do those MATHproblems correctly from both packets 2 & 3?) • Correct quiz 3; Waves packet 4 quiz • Computers: CPU’s (remember – you should have saved Doc’s in your I drive, so open that & keep going.) • HW: Earthquake packet notes (due Monday) NOTE that you WILL be able to use anything from this day’s asst on your waves test next week!

  7. Mon Feb 3 • 1 partner logs in immediately • Correct quiz 4 • Turn in Earthquake notes • Computers: CPU’s • HW: waves packet 5 NOTES & then draw a line & ANSWER 19 questions.

  8. Tues Feb 4 • 1 partner logs in immediately • Turn in packet 5 work … • key to packet 5 self-check questions. • Collect packet 5 (QUIZ????) • Computers: FINISH CPU’s (last day) • HW: (see handout; 80 b & 88 you may skip; note important ones listed in pink below!) • page 386 #22-25 • Page 391 #27 and 29 • Page 396 #40-44, 47-48, 50-52, 54-56, 57, 59, 62-66, 68, 75-79, 80 a&c only, 81-82, 84, 89-91, 93, • Page 876 # 8 & 9 • Page 401 #6 and 8 • =43 problems over 2 days (Due Thursday) Also, note some of them are EXTREMELY important: page 396 #57, 68, 79c, 81, 82, 93

  9. Wed Feb 5 • 1 person logs in immediately?? (need to finish CPU’s?) • Grade Quiz 5 • Go over Slinky lab (correct with red pen) • Go over Guided Notes • Maybe some time to finish CPU’s ???? • when done, work on book problems… • HW = FINISH Book problems (note very very very important ones =page 396 #57, 68, 79c, 81, 82, 93) Due Thursday

  10. Thurs Feb 6 • Go over CPU’s (lecture notes) • Bill Nye Waves & worksheet (½ hour) • Need to make up if absent! • Asst: Answer 50 self-check questions quickly WITHOUT looking at any notes, the book, or anything else. This is to be treated like a “pre-test”; unit test is this PLUS the book problems. If you end up having to leave a question blank (or have one you’re not sure about) THEN go back after you're all done with a different color. This will tell you exactly what you need to study this weekend!

  11. qreflected qincident CPU Sims 1-2 in brief • Sim 1, Relationships: • NOTE – you would change amplitude or frequency by changing the source; change velocity by changing water • If medium constant, velocity constant and wavelength & frequency change INDIRECTLY (one increases and the other decreases) ... 1st graph in excel • If medium changes, frequency constant and velocity & wavelength change DIRECTLY (either both increase or both decrease) ... Graph 2 in excel • Amplitude NOT dependent on anything (vel, wavelength, or frequency), nor can it change any of those .. First data table in Word, last graph in excel • Sim 2, Reflections: • Law of Reflection says incidence angle = reflection angle (don’t forget both must be measured from the normal!)

  12. CPU Sims 3-4 in brief • Sim 3, Depth (changing medium) Effects: • If medium changes, frequency constant and velocity & wavelength change DIRECTLY (either both increase or both decrease) ... Graph 2 in excel • If medium changes AT AN ANGLE, then because PART of the wave slows down or speeds up, the wave will BEND. • Notice in middle picture, faster medium has bigger angle. (We will learn the math equation for this when we do Light/Optics.) • Sim 4, Diffraction: • Neat pictures of single-slit diffraction & double-slit diffraction (double-slit causes an interference pattern with nodes & antinodes) • Learn: longer wavelengths and/or smaller slits cause more diffraction

  13. Fri Feb 7 (copy next day too!) • Note about inverse vs reciprocal, and angle measurements • Go over … • Concepts (57, 84, 87, 91, 6 & 8) • Other book problems? • 50 Self-Check questions (#16, 47, others??) • Bill Nye answers (if time) • HW – MEMORIZE and STUDY (email if questions!) TEST

  14. Mon Feb 10 • TEST • Asst: (a) Guided notes on SOUND chapter 15 3. Need to turn in • All (1-50) self-check questions • ALL Handouts IT IS EXTREMELY IMPORTANT YOU ARE IN CLASS (ON TIME) THE NEXT 2 DAYS AS WE START SOUND!!!
