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.
