4/30/12-5/11/12

• Mon 4/30:  Questions on review?  Turn in 14+15 Review.  Take 14+15 Review.  When done, start Nuclear Physics (Chapter 25). 
• Wed 5/2:  More on Nuclear Physics:  nuclear stability and binding energy.  Binding energy problems.  Start working on Astronomy Project.
• Fri 5/4:  Check off binding energy problems.  Nuclear decay and half-life.  Work on problems.  Group time on projects.
• Tues 5/8:  Check off problems.  Nuclear fission and nuclear fusion.  Fundamental forces and classification of particles.  Prepare for Libary Research on Thursday.
• Thur 5/10:  Library Research for Astronomy Project.  This is our main day for research, so get as much done as possible.  By the end of the period, you will hopefully have your resources selected and citations written down, a summary of what you want to cover, and a strong idea of your visual aide.  We will begin presenting next week on Wednesday 5/16.

14+15 Test on Monday 4/30!

Come in on Monday prepared to ask questions and take the test.  The 14+15 Review sheet is due before the test as usual.  Here are numeric answers for the test:

1.  f = 28 cm,  M = -.48, small, real, inverted
2.  q = 11.3 cm (use substitution to get rid of one of the variables, p or q)

3.  concave mirror, M = - 20.0, larger, real, inverted
4.  q = 170 cm, M = -2.7, h' = 22 cm
5.  f = 200. cm, M = 1.25, larger, upright, virtual
6.  23 degrees

7.  critical angle is 37 degrees, so refracted

(p.s. For students in 4th period, the answer to #20 on the 14+15 problems is 48 cm.  We will go over this on Monday 4/30).

Make sure that you know how to use ray diagrams to locate an image.  You will be required to do one, although you can choose a lens problem or a mirror problem.  Make sure that you can show the refraction of light through a substance.

Enjoy your week-end and start thinking about that Astronomy Project!!

Beginning of 4th Quarter

Late Work/Extra Credit Deadline tomorrow (4/9) by 3:30 pm! Musical Instruments Too!

I have just finished entering the grades for your Spring Inquiry Labs and your 12+13 Tests.  The only remaining assignment for the Quarter is the Musical Instrument Project.  I can't wait to see what you bring in tomorrow!  Don't let some of the amazing instruments from last week discourage you.  Those were some of the best instruments I have seen in 10 years of doing this project.  And remember that the write-up is just as important as the actual instrument.  Check your grade on Edbox and see if you have any questions.
