• Thursday 3/31:   Computer Sound Lab.  Doppler Effect, Sound Intensity, and more on Resonance. 
• Friday 4/1:  Check off Pendulum and Spring Problems. Harmonic Series Equations. HW p. 499 1-4.   (whoops, save this for Monday).  Sound Intensity.  HW p. 188 1-5 instead.  Introduce Musical Instrument Project (due Thursday 4/14).

Happy Spring Break!!

I hope that you enjoy your break!  I have just updated grades, so check them and see if you can find any of your missing assignments.  This is a great time to make up missing homework, finish labs, and do Extra Credit.  Check the documents section of this website if you have forgotten what you can do for Extra Credit.  The end of the 3rd quarter is Thursday, April 7th.  E-mail me if you have any questions:  mkenny@pps.k12.or.us
