Thursday, April 9, 2009 - Block 3

Announced students selected for IB portfolio.

Handed back Heat and Thermo test and went over every question.

Outlined plans for next 4 1/2 weeks before IB Physics test.

Started relativity in last 20 minutes of class.

Heat, Temperature, and Thermodynamics Test

Got signatures for last few PSOW including Luminosity of Sun Lab

Tuesday, April 7, 2009

Tuesday, April 7, 2009 - Block 3

Students cleared desks and I handed back graded pendulum labs, specific heat labs, and PSOW forms.

Answered questions and then students signed PSOW forms.

I collected the labs and PSOW from students who are doing IB.

Very few students worked on the review problems for tomorrow's test.

I did one problem on the board and then gave the students time in class to work on some of the remaining problems - answering questions as they arose.

Test tomorrow on heat, temperature, and thermodynamics.

Monday, April 6, 2009 - Block 3

Showed parafin light detector. Demonstrated how it worked with 1-1 and 2-1 light bulbs. Gave IB students option of doing one more data and results lab. Due Wed morning at the very latest.

Two group did it.

Went over RA 17.1, 17.2

Showed rest of Hewitt video on Change of State.

Handed out review problem set in preparation for test on Wednesday.

Friday, April 3, 2009

Heat transfer by radiation
Wien's Law
Stefan-Boltzman Equation

Worked some examples
Gave students the "Nobel Prize" problem. Students didn't like that one much.

Thursday, April 2, 2009 - Block 3

Collected all remaining IB labs.
Collected RA 17.1
RA 17.2 is due tomorrow.
Told students that starting tomorrow, no late work will be accepted. It will receive a zero grade.

Handed out heat engine problem and gave students time in class to work on it.

Lectured on the 2nd Law of Thermodynamics

Wednesday, Aprile 1, 2009 - Block 3

Reviewed yesterday's simulations and data base exercise.

Told students that I need hardcopies of the calorimetry labs by tomorrow. Emailing them to me does not count.

Intro to thermodynamics.
Reviewed concepts.
Went over first law of thermodynamics.
Showed how work = pressure * volume = area under the curve in a PV diagram

Did worksheets on sign convention.

Showed the four adiabatic processes: constant pressure (isobaric), constant volume, constant temperature (isothermal), no heat exchange (adiabatic). Explained the computational advantages of each and showed what they look like on a PV diagram.
