Went over RA 17.2
Showed how to draw schematics of thermodynamic systems.

Went over First Law of Thermo sign convention worksheet.

Did problem of heat engine with ideal gas as a class.

Handed out "Save Jack" problem for IB Lab (Planning (A), Planning (B), Data Collection, Data Analysis, Conclusions. Watched part of Titanic to get "feel" and background for the problem. Plan on doing lab next week.

Handed out Kinetic Theory Worksheets.

Travis ran the class going over the worksheet. Great Job Travis!

Tomorrow we will go over any questions from Thermal Problems worksheet and the summary review sheet.

Friday: Test on Heat

Answered questions and talked briefly about the Newton's Cooling Lab. Students will answer the analysis questions, being sure to say in their answers what they are answering, by Friday.

Handed back Heat Capacity Labs

Students spent the period working on the Thermal Problems Worksheet.

Test on Friday

Students set up for Newton's Cooling Lab.

While running, I reviewed the Heat Capacity Lab with emphasis on controlling variables, especially heat loss.

When students write up the Power from the Sun Lab, I want to see at least 5 main points in reviewing the procedure and 5 main points in modifying or improving the procedure. This lab will be written up to satisfy the data collection, data processing, and conclusions sections of an IB lab.

Students analyzed Newton's Cooling curves using the automatic curve fit function. Students looked at the coefficients for the fit curve. If they were not reasonable, students entered in the Room Temperature and rechecked the coefficients. Students got reasonable results with this correction.

Students wrote up questions 1-9 in the lab analysis section. If they did not finish, finish for homework.
