Weekend Hmwk

P. 309#1, p.348#11,26,27, READ 320-325.
Today in class we looked at Interference (constructive and destructive) and finished up the slinky waves packet. Next week we'll have our cumulative exam on Wed and the rest of the week will be spent looking at applications of what you've learned about waves so far... with Sound and Light.

Review materials for cumulative exam:
Missed exam questions you've written down in your notes,
Chemistry notes and worksheets
Notes on Earth's Interior and Thermal Energy
Notes on Radioactivity

Optional Assignment to come...

http://phet.colorado.edu/sims/blackbody-spectrum/blackbody-spectrum_en.html
For those who have grades on the border and anticipate needing some extra help, take a look at this simulation. I will not post questions about this quite yet, but hope to by Monday so you can use it to follow along with topics in class and use for points if needed.

5-19

Today in class we worked more on the slinky - waves lab and Mr. Freeman became an exert in slinky detangling.
Homework for tonight:
Read 294-299 if you didn't get to it in class,
p. 297#1 p. 299#6-7 (you can do these - just algebra and using your units we've learned about)
Read p. 306-309 to prepare for class tomorrow.

Classes tomorrow will learn about interference and some review material for Wednesday's exam will be posted online tomorrow. Want to start early? Review missed questions from other exams plus your notes on chemistry.

5-17



Today in class: Intro to Waves and Oscillations
Examples of periodic events in life...
Notes: velocity (v) (review)
, frequency (f)(cycles per second.... = Hertz (Hz)),
and Period (T) (time per cycle.... seconds)

Period is the reciprocal of Frequency, so...

1/T = f

1/f = T

Demonstration / measurement of how weight on a spring affects period and frequency of bounce - oscillations: More weight on spring: greater period, lower frequency. (non-linear relationship)

Demonstration of how slinky - waves investigation will go tomorrow; working in small groups and analyzing/measuring factors about waves.

Reminder: Cumulative Exam on Wednesday (next week!!) Time to start studying old missed test questions and skimming through notes!

5-9

Tonight's HMWK: finish ionic bonding practice/quiz WS - remember to name all compounds on both sides. Also read p. 688-692 and work #1-4 on p. 692 and # 11, 14, 17, 21 on p. 714

Today in class: Ionic Bonding (application of all the lewis dot diagrams and our discussions of stability last week) and Naming Ionic Compounds.

Tomorrow: Polyatomic Ions (they're easy to add once you get basic ideas of Ionic bonds)
AND some relation to Acid/Base chemistry and Earth Science stuff...

Wednesday: Quiz over elements #1-40 and your 15 additional: Ag, Sn, I, Xe, Ba, W, Pt, Au, Hg, Pb, Bi, Rn, Ra, U, Pu.
