4. Continue doing Review Questions from IB Physics 1
5. Uncertainty quiz on Friday.
It is important students keep up because next week we go full steam ahead into new material for IB Physics 2.
Handed back redos of computer uncertainty assignment. Asked student to again redo if they did not get it all correct.
Quiz on relative uncertainty.
Asked students to correct mistakes.
Showed Hewitt video on Scaling.
Handed out Reading Assignment due Friday.
I set up a computer with a program so that students could check their BB Pancake Lab results before handing it in. I emailed this program to students as well.

Monday, Sept 21, 2009 - 3B
Hand back computer graphs and spreadsheets on uncertainty.
For spreadsheet exercise on uncertainty, students should not have to type in any values. They should just say one cell equals another and then format that cell to have the correct number of sig figs.
Have students redo the exercises until they get them correct.
Go over uncertainty examples using both method of relative uncertainty and min max method.
Hand back and go over RA 10.
Do BB Pancake Lab.

Thursday, Sept 17, 2009 - 3B
Collected RA chapter 10
Finish computer exercises if students didn't finish in class and email me the results if they didn't hand in printed results in class.
Work on Quia quiz for review problems in IB Physics 1.
Took students to computer lab.
Students redid spreadsheet lab on round objects but included error bars and linest results for uncertainty in slope. Students printed out plots.
Loaded the Excel spreadsheet on uncertainties for each student. Students were to do all the problems using the computer and then rounding the results to 2 sig figs in uncertainty and then the same number of decimal places for the number. Students printed out the spreadsheet and handed it in.

Homework:
1. Bring back completed Parent Notification form
2. Bring back completed Course Overview form
3. Cover textbook
4. Students randomly chose a number corresponding to a chapter in the textbook (ch 2-9) for next time, please
a. draw a concept map of the ideas of the chapter
b. identify important vocabulary
c. come up with 3 questions or problems that illustrate the main ideas of the chapter.
5. Log onto Quia and do the exercises:
a. Significant Digits
b. Rounding
c. Scientific Notation
Got textbooks - bring them to class on Tuesday with a structurally sound cover that is not taped to the book
Went over course expectation form.
Handed out Quia usernames and passwords.
Explained Quia assignments to be done for next time. These three are really an into into how to input answers into the fill in questions for Quia.
I mentioned the article I read on REM sleep and solving problems. It's all about making connections. I want the students in this class to make connections between the various concepts. Do not view the subject as entirely compartmentalized.
I am willing to hold after-school sessions to help students prepare for IB but these have to be initiated by the students. Students have to tell me what they would like to cover. I do not force students to come.
Students drew a number corresponding to a chapter in the text. Students were asked to review the chapter, prepare a concept map, identify vocabulary, and come up with 3 questions or problems that illustrated the important points of the chapter.
Showed set-up for iron wire demo. Asked students to describe what physics they say.
I will do this demo for my APS students but since it shows so much of what we will cover in IB Physics 2 I decided to show it here as well.
We touched on electric circuits, showing that you must have a closed circuit to conduct electricity. Showed that the ammeter (current measuring device) is hook up in series in the circuit. Showed the concept of pressure in using the C-clamps.
When I turned on the voltage, the wire began to sag as it heated. This indicates linear expansion with temperature. The class identified the important variables and we were able to derive an equation for linear expansion.
I had to keep increasing the voltage to maintain the current. The resistance of the wire increased with temperature. I = V/R
As the wire continued to heat, it turned red and then red-orange. It got hot enough to glow in visible light.
Students observed convection currents, or the affect of the convection currents on the refraction of light.
When the wire got hot enough, a magnet fell off showing that there was a change in the magnetism of the wire (ferromagnetism --> paramagnetism)
When the power was shut off, the wire cooled and shrank, but then suddenly expanded again before continuing to shrink. I explained that was a phase change between two crystal structures, the expansion occurred when it transitioned to the less dense structure as it cooled.
Cool demo.
Also demonstrated the diamagnetism of grapes. Asked for a hypothesis, will the grapes be attracted, repelled, or not affected? The grapes, connected by a straw, hung by a thread. They actually were repelled by the magnet showing it was not the same effect as ferromagnetism.
Finished by starting to show powerpoint for Topic 1. Didn't get very far before end of period.
Class went very well.
