Week of 11/10

Monday: Notes: Thermal E (more), Food E, and Nuclear Fission/Fusion
Time to work on quiz/hmwk worksheet - due Tuesday  (see link from last week)
Discuss/help on answers to worksheet


Tuesday:  Doing work on/by a gas or air - changing temperature as a result, and ways this is manipulated (Air conditioning, refrigeration)
Here's a cool video on it  (link will work through wed I believe)


Wednesday:  Notes/Demonstrations: POWER
We'll do some hands-on measurement of work, GPE, and Power after we move through the notes.
HMWK Assigned (Due Friday)  READ p. 272-277, p.277#3-7

Thursday:  Notes: Thermodynamics
Re-do Wednesday's experiment (work = work) using a ramp or lifting a wheeled cart straight up... with Friction this time, and apply percent efficiency and thermodynamic rules to the explanation of why the work done when using a ramp is different from the work done in simply lifting an object.

New optional assignment:  The Physics Of: __________   
The next time you come up with an interesting question about how/why/if something works, research the physics behind it and present your findings to class!  If you think your idea is too wild or not related to Physics, the answer is NO!  If you're looking for a question to research; I can help give you ideas.
Presentations may be any format; more points based on the best understanding/explanation/research of the phenomena.
Present on Tuesday, Nov 25.


Friday:  Thermodynamics and populations - graphing exercise, POWER demonstrations and measurements - Fun!  Introduction to machines/demonstrations.
HMWK Assigned:  Read p. 160-165, p. 165#1-7 (Due Tuesday)

Monday: Power demonstrations/calculations, start Notes on Machines

Tuesday: Practice problems for exam (some classes)
Review materials available:
Energy Review Quiz
gpe/ke calculations
GPE - KE conversion task
Reading guide / STUDY GUIDE
E conservation problems



Wednesday: Levers Lab

Thursday: Review - Work, Energy, Thermodynamics, Machines

Friday: Test!

Monday/Tuesday before Thanksgiving:  Begin ASTRONOMY!
