Physical Science 20 - Oct 7

Today in class we finished learning about molar ratios and started doing some stoichiometry problems.  We were a little ahead in Period 2 so we did slides 6-11 in the stoichiometry notes powerpoint.  In Period 3, we did slides 4-10.  Students were then given sometime to work on Assignment C25 with the remainder of the period.  We will go over this tomorrow.

Physical Science 20 - Oct 6

Today we had the first day of stoichiometry.  We learned about molar ratios and how we can get those from a balanced chemical equation.  Afterwards, we did a couple of examples and but students didn't get enough time to work on Assignment C23.  This will be assigned tomorrow and due the next day.  We will continue on tomorrow by looking at stoichiometry problems.  The notes we took today are found on a powerpoint called Stoichiometry Notes and we just did slides 1-7. 

Physical Science 20 - Oct 5

Today in class we went over Assignment C21 after I checked it.  Students then spent the rest of the class working on Assignment C22.  I will check this tomorrow.  C22 was a review of all the different molar conversions that we done with this outcome. This is important for the test we are going to have on Friday.  

Physics 30 - Oct 5

Today we finished up our notes on static and kinetic friction and looked at an example of friction in two dimensions.  We did examples 16 and started example 17. This was covered on slides 49-56 in the powerpoint. Students were then given some time to work on Assignment 2.5.  Reminder that tomorrow is your first in class assignment for Unit 2.  This covers Assignments 2.1-2.4.

Physics 30 - Oct 2

Today in class we finished up friction by doing examples 13 and 14 as well as learning about static friction and friction on an angle.  Students had a little time at the end to work on Assignment 2.5.  We will take this up on Monday.




Gotcha.....Most students were absent today due to the U of S open house therefore I gave the students a work period today to prepare for their in class assignment next Tuesday.  Monday we will be doing what is described above.  There will be no other work period for students who were away today.

Physical Science 20 - Oct 2

Today I checked Assignment C20 and students handed in their reports for Lab C2.  After this, we then learned how to convert from moles of a gas to liters of a gas at Standard Temperature and Pressure (or STP).  At STP, 1 mole of gas occupies 22.4 L of space.  We went through a couple of examples and then worked on Assignment C21.  I will check this on Monday.  Most students finished it in class.  They then started working on Assignment C22, which is a review of everything we have learned so far with the mole. We will work on this more tomorrow.

Physics 30 - Oct 1

Today we continued on the unit by looking at friction and how friction works.  We talked about what friction depends on and then we studied kinetic friction specifically.  We started example 13 in the notes.  Tomorrow we will finish example 13, do example 14 and then look at static friction.
