Physical Science 20 - Feb 4

Today students learned how to name compounds that had multiple cationic charges.  This involved using the Stock System and roman numerals.  We also learned the classical system and how it differs form the Stock System.  We will be using the stock system moving forward.  After this, students learned how to create formulas and name compounds that involved polyatomic ions.  These are groups of atoms that are bonded together that have an overall ionic charge.  Forming compounds with the polyatomic ions is no different than before - we still want to balance our charges and have no overall ionic charge.  The notes we took today were from slides 43-60.  Students spent the remainder of the class working on Assignments C3 and C4.  We will go over these tomorrow at then look at how to name hydrated compounds and acids.

Physics 30 - Feb 3

Today in class we finished up our notes on the kinematics review.  I then introduced the kinematic equations to students and we went through examples 3 - 6. The kinematic equations apply in situations where an object is undergoing constant acceleration.  The notes were all taken from slides 13-21. Students were assigned Assignments 1.1 and 1.2, however they do not have textbooks yet to do these questions.  Students can access the pdf version of the textbook found in the Physics 30 course notes link if they want to get started on the questions.  I will handout textbooks next week after schedule changes end. Tomorrow we will be doing a particularly difficult type of kinematic problem called a twin object problem.

Today we went over assignment C1. I didn't check this assignment and we didn't go through all of the answers.  Students are to access the answer keys if they want to check their work.  The answer keys are found in the Chemistry folder under the Physical Science 20 Course Notes link along the side. We learned about ionic compounds today and how to write formulas for them.  This involved balancing ionic charges.  This was all covered on slides 31-42 on the Chemistry Notes powerpoint. Students then had the rest of class to work on Assignments C2. We will be taking this up tomorrow and moving on and looking at polyatomic ions as well as multiple cationic charges.

Physics 30 - Feb 2

Today we got started on the new Physics 30 course which meant we started refreshing our knowledge of motion.  We started with Unit 1 on Kinematics and cover slides 1-13 of the powerpoint called Unit 1 Notes.  Students followed along with a set of handout notes that they picked up today in class.  Tomorrow we will finish this review and begin to look at the kinematic equations.

Physical Science 20 - Feb 2

Today we started learning how to name compounds.  Most of this week we will be reviewing the rules that you learned in Grade 10 science on how to name compounds.  Today we looked at how to name elements and molecular compounds.  This was covered on slides 1-27 in the powerpoint called Nomenclature Notes.  It is found in the Course Notes link on the right hand side of this webpage in the chemistry folder.  In particular the notes folder in chemistry.  Students were assigned Assignment C1 to have done for tomorrow.  Check the answer key folder tomorrow for the answers to that assignment.  Tomorrow we are moving on and learning how to name and make a formula for an ionic compound.

Welcome everyone to your last semester in high school! Hopefully...if all goes well.  Bookmark this page as it will be very helpful to you moving forward in Physics 30.  Today in class we just talked about classroom expectations and procedures as well as went through the course outline.  Tomorrow we will jump into our first unit on kinematics.

Physical Science 20 - Feb 1

Hello Everyone!!  Welcome to second semester in your grade 11 year.  And welcome to Physical Science 20!  The purpose of this website is to keep students up to date with what we are doing in class and to serve as a place to go to to find course material.  Bookmark it as you should be accessing it quite a bit throughout the semester.  The links on the side will be particularly helpful, especially the one called Physical Science 20 Course Notes.  You will be visiting there often.  Today in class we just went over the course outline and talked about classroom expectations.  Tomorrow we will get started with Nomenclature and chemistry.
