Monday, Oct 26, 2009 - Blocks 1B, 4B
Went over how to describe the direction of vectors as some angle so many degrees and in what direction from one of the coordinate axes (N S E W)
Did several examples in class of describing vectors.
Checked over homework sheets for constructions of parallelograms while students measured angles and described vectors.
Handed out packet on problem solving strategy for d,s,t. Students worked on packet.
If they did not finish, they were to finish the packet for homework.
Showed some demos with dry ice.
In block 4, we actually obtained and plotted temperature and pressure points, plotted the graph, and extrapolated to zero pressure to find absolute zero. Also made quarters squeal when pressed into dry ice.

Collected graphical addition of vector worksheet.
Handed out packet on problem solving strategy for d,s,t problems with no acceleration. Students worked on it in class. If they finished, they could check their answers with mine. If they didn't finish, I asked them to finish for homework.
There is an optional Quia available for additional practice on d,s,t problems.
Students did the ball on track lab, measuring the speed of the ball and comparing their result to the motion detector measurement. Students wrote up procedure for lab, gave results, and handed it in.

Handed back and went over test.
Asked who made money from reaction time lab.
Went over RA 1.1
Students tried measuring the speed of a ball lab. Only two groups got speeds that I could check with computer. The idea was to have students write down the procedure so that another student in the group could follow it - just ran out of time.
For homework, handed out worksheet on adding vectors graphically.

Test on Measurement, Scientific Notation, Graphs, Unit Conversions, Metric Prefixes
Hand out RA 1.1 - due Tues

Test on Measurement, Scientific Notation, Graphs, Unit Conversions, Metric Prefixes
When students were done, I put a data table on the board and asked students to graph the data. Do you get a linear trend? No
We then manipulated the data by squaring one of the variables. Students replotted the data and did get a linear trend. Students drew a best fit straight line through the origin and found the slope. Using the equation of the straight line though the origin, y = m * x, they got the relationship between the variables.
Hand out RA 1.1 - due Mon

Handed back tests.
Asked if there were any questions.
Went around and answered individual questions.
Took students to computer lab and did Excel Spreadsheet Lab for round objects.
Unfortunately, we had an assembly that day that chopped out 15 minutes of class time. Students did not finish computer lab.
Asked students to redo lab at home if they wanted credit.
I emailed the data table to save time.

HW: finish graph and hand in graph and data table on Friday.
Students took Material Science test. Took about 40 min including survey.
Talked about graphs. In this class we make line graphs to show the relationship between variables.
Divided students into groups of 3 and did round object lab. Students are to finish the graphs for HW and hand in on Monday.
