Happy Spring Break!

Many of you have already turned in your Spring Inquiry Lab through a hard copy or e-mail and through turnitin.com.  Keep them coming in!  There are still many out there.   Also, remember that you can work on your Musical Instrument Project over break if you would like.  It will be due on Wed/Thurs, April 10-11, so if you don't come up with anything over break, you will still have 9-10 days to finish it when we get back.

Enjoy your time off!

3/18-3/22

There is a SPARK lecture on Monday 3/18 on Engineering.

• Mon 3/18:  Check off wave problems 1-5 and go over.  Go over string tension equation and sound intensity.  Problems 7-15 due Thurs/Fri.  Spring Inquiry Final Draft due Tues/Wed.  Include color-marked draft with your final draft.
• Tues/Wed 3/19-3/20:  Turn in Spring Inquiry final draft and color-marked draft.   Finish going over sound intensity.  Resonance and the Tacoma Narrows Bridge.  Work on problems.
• Thurs/Fri 3/21-3/22:  Check off problems and go over.  Computer Sound Lab. Harmonics and harmonics equation.   Work on problems 17-20.  Hand-out Musical Instrument Project.   You may work on it over Spring Break if you have time, but it will not be due until the 2nd week after we come back (4/10-4/11).

3/11-3/15

Physics in Motion Project due this week!

• Mon 3/11:  Introduce waves.  What are you doing for the math problem in your Motion Project?  2nd Draft (preferably typed) of Spring Inquiry due Tues/Wed for peer review.
• Tues/Wed 3/12-3/13:  Exchange Spring inquiry labs and color-mark.  More on waves, including wave equation.  Do problems 1-6 for Thurs/Fri.  Time to assemble/work on Physics in Motion Project posters.
• Thurs/Fri 3/14-3/15:  10 minutes to get Physics in Motion Posters finished up.  Gallery walk to read and evaluate Physics in Motion posters.  Evaluate your own and 3 others.  Check off Problems 1-6 on wave worksheet and go over.  More on waves, including tension in a string.  Do problems 7-9 for Monday.  Final Draft of Spring Inquiry due Tues/Wed of next week.  Please submit your paper on turnitin.com as well as turning in a hard copy.  I will provide you with information on how to add this class in turnitin.com next week.
