Physics 30 - Feb 27

Today we just had a review period for the in class assignment as well as the exam.  The date for the exam has been moved to March 9 and the in class assignment is now on March 2 due to my illness yesterday.  We will be beginning the new unit on Tuesday, March 3.  If you want the notes outline for the the second unit, you should print them from the blog.

Physics 30 - Feb 25

Today we finished up the first unit by looking at free fall problems.  These are just special kinematics problems that have a constant acceleration of gravity, which is 9.8 m/s/s.  We went through one example and then students had the rest of class to work on Assignment 1.7.  Tomorrow we are doing our first in class assignment on Unit 1.  Make sure you know how to do questions from every assignment in the first unit.

Physical Science 20 - Feb 25

Today in class we learned how to create a net ionic equation from a balanced chemical equation representing a double replacement reaction.  This involved figuring out the products and their final states, balancing them, figuring out the overall ionic equation and then determining the ions that formed the precipitate.  This allowed us to make a net ionic equation.  Students then had the rest of the period to work on Assignment C15.  We will go over this tomorrow.

This also completes the outcome on reactions for us.  Tomorrow we will begin to look at Math and the Mole.

Physics 30 - Feb 24

Today we just worked on Assignment 1.6.  Tomorrow we will do our final concept on free fall problems.  This stuff will be covered on the in class assignment on Thursday.

Physical Science 20 - Feb 24

Today in class we went over Assignment C14 after I checked it.  We then started to learn how to predict the products of a double replacement reaction.  This involved determining the states that the final products will be in as well as understanding what aqueous means.  We learned about dissociation of soluble ionic compounds as well as a couple of different type of chemical reactions.  The overall ionic equation and the net ionic equation.   These notes were all covered on slides 52-62 of the Chemical Reactions powerpoint.  Students were given slide 62 as homework, which involved determining the solubility of some ionic compounds using a solubility table.  We will go over this tomorrow.

Physics 30 - Feb 23

Welcome back everyone!  Today we looked at a particular tricky example called a twin object problem.  This type of problem involved looking at the motion of two separate objects that are linked somehow.  We ended up developing new equations based on kinematics and would have to employ the quadratic formula to solve these new equations.  Assignment 1.6 was assigned but students will be given some time on tomorrow to work on it. 

We are also approaching the end of the unit.  This means that some things will be happening.  The first In Class Assignment is set for Thursday, Feb 26.  The first unit exam is set for a week after that on Wed, March 4.  

Physical Science 20 - Feb 23

Welcome back everyone.  Today I checked Assignments C12 and C13. We then learned how to predict whether or not a single replacement reaction will happen.  To do this, you need to have access to an activity series table, which I handed out today.  In order for an element to be replaced, it has to have be placed lower on the activity series that the element that is replacing it.  It that is not the case, then no reaction will occur.  Be careful to form compounds correctly making sure to balance your charges.  As well, make sure to balance your equations at the end if you have a reaction.

I assigned Assignment C14 at the end of class and I will check this tomorrow.  Tomorrow we will continue on and look at whether or not a double replacement reaction will complete.

Friday 13 February 2015

Physics 30 - Feb 13

Today we learned about the equations that govern motion with constant acceleration, called the kinematics equations.  We did a couple of problems associated with using these new equations and then I assigned Assignment 1.5.  Work on this over the break as well as any other assignment that you need to get caught up on.  When we get back, we will finish up the unit as well.  This means we will have our first class assignment and the unit exam will occur soon after that.  The first in class assignment is scheduled for Thursday, Feb 26.  Have a great break everyone.

Physical Science 20 - Feb 13

Welcome to the winter break everyone!!  We will have a little bit of work to do over the break.  Today we learned about the different types of chemical reactions and how to identify them.  We also learned how to predict the products of a reaction based on what type of reaction it is.  If you can figure out the type of chemical reaction based on the reactants, then determining the products is easy as long as you know how to make chemical formulas.  That is why nomenclature was so important.

Over the break, students should complete Assignments C12 and C13.  As well, review nomenclature.  There are extra worksheets in the chemistry folder for those of you that want more practice.  When we get back, we will learn about determine whether or not a reaction will occur.

Physics 30 - Feb 12

Today we had a work period to practice on Assignment 1.4. Tomorrow we will be looking at the kinematics equations and the problems associated with those.

Physical Science 20 - Feb 12

Today students wrote the quiz on nomenclature.  I also checked Assignments C9 and C10 while the quiz was going on.  Please check the answers posted in the answer key section in the Course Notes link.  After students completed the quiz, they learned about changing a word equation into a chemical equation using their knowledge of nomenclature.  I assigned Assignment C11 for tomorrow as well as a video from the Course videos link.  It is linked here.  Please watch this for tomorrow's class.

For Assignment C11 - do not do questions 2,3 and 7 unless you understand a combustion reaction and the products of a combustion reaction.  As well for question 4, the products should be potassium nitrate and water NOT potassium hydroxide and water.

Wednesday 11 February 2015

Physics 30 - Feb 11

Today we finished going over example 7 in the notes.  It was a rather long example where we figured out a bunch of stuff from a velocity time graph.  We also did example 8.  In this example, we learned how to translate a position time graph into a velocity time graph.  For the rest of class we worked on Assignment 1.4.  We will have more time to do this tomorrow.

Physical Science 20 - Feb 11

Today students handed in Assignment C8 and I marked them as your first assignment mark.  We then learned how to balance chemical equations and I taught students a short hand method for balancing equations. We looked at a couple of examples and then students spent the rest of class working on Assignments C9 and C10.  These are due tomorrow.  As well, remember that you have your nomenclature quiz tomorrow.

Tuesday 10 February 2015

Physics 30 - Feb 10

We started looking at accelerated motion today in class.  The definition for acceleration was given and we also looked at a new type of graph called a velocity time graph.  We learned another way of getting information from a graph as well.  By calculating the area under a graph, we can get a whole bunch of information from a graph, most importantly the displacement of an object from a velocity time graph.  Tomorrow we will look at example 7 and example 8 and hopefully get a chance to work on Assignment 1.4.

Physical Science 20 - Feb 10

Today in class I checked Assignment C6 on naming acids.  Make sure to check your answers on the blog.  I also assigned Assignments C7 and C8.  C7 is on naming organic substances whereas C8 is a review of all the nomenclature that we have done so far.  I will check C7 tomorrow and take in C8 to be marked.  Have both of these done tomorrow.

We also started on chemical reactions today.  It was just a review from Science 10.  We finished off by looking at balancing equations and this is where we will begin tomorrow.

I have set the date for our first quiz in the course.  It is on Thursday, Feb 12.  It will cover all of the stuff we have done so far on naming with the exception of C7.  You are going to want to pay particular attention to Assignment C8.  This is the assignment that will closely reflect what the quiz will be like.

Monday 9 February 2015

Physics 30 - Feb 9

Today we learned about the difference between velocity and speed.  Velocity is a vector quantity and therefore requires a direction, speed is a scalar quantity and does not need direction.  We learned how to calculate velocity from a position time graph.  We also did a complicated example where we pulled a lot of information from a position time graph.  This was example 5. Students had about 10 minutes left to work an Assignment 1.3.  Tomorrow we will look at acceleration and accelerated motion.

Physical Science 20 - Feb 9

Today I checked Assignments C3, C4, C5. We then learned how to name acids and organic molecules.  We just learned the basics for naming hydrocarbons.  Student will have to have Assignment C6 completed for tomorrow.  Assignment C7 on organic nomenclature will be due on Wednesday. Tomorrow we will start looking at chemical reactions and how to balance them.

Friday 6 February 2015

Physics 30 - Feb 6

Today we got up to Assignment 1.2 by finishing an example on position time graphs.  Students we handed out textbooks today as well and were given time to work on Assignments 1.1 and 1.2.  We will take these up on Monday and continue on by looking at speed and velocity.

Physical Science 20 - Feb 6

Today in class we learned how to use the Stock naming system when encountering compounds that involve elements that can have multiple cationic charges.  This system involves using Roman numerals to denote the positive charge that the ion has.  We also discussed the differences between this and the classical systems which utilized the latin names of the elements.

We also learned how to name hydrated compounds.  This wasn't much different than what we have already done.  We just have one more step of adding a name for the water molecules that are in the compound.

Students spent the majority of class working on Assignment C3, C4 and C5 which are all going to be checked for completion on Monday.

On Monday we will look at how to name acids as well as starting to learn how to name organic compounds.

Thursday 5 February 2015

Physics 30 - Feb 5

Today in class we finished up our review of physics 20 by looking at graphing and relationships.  We then continued on and started looking at kinematics in one dimension.  Definitions of vectors and scalars were given along with position, displacement and distance.  We did a couple of examples that allowed us to see the difference between distance and displacement.  Tomorrow we will finish this up by looking at a position time graph and understanding the information that you get from it.  Students will get their textbooks tomorrow as well as getting some time to work on Assignment 1.1 and 1.2.

Physical Science 20 - Feb 5

Today in class I checked Assignments C1 and C2 and we quickly went over the answers.  For students who didn't get some of the answers or who were absent today, check the answer key folder in the Physical Science 20 Course Notes link.  We continued on today learning about polyatomic ions and how to write formulas for them.  Students had the rest of class to work on Assignment C3 which involved naming and writing formulas for compounds involving polyatomic ions.  This is not due tomorrow however due to some issues I had in class getting information to the students.  This will be due on Monday along with Assignment C4 which we will learn about tomorrow.

Wednesday 4 February 2015

Physics 30 - Feb 4

Today we started into the notes.  It was a review of the skills you should have learned in physics 20/physical science 20.  We learned about units, significant figures, scientific notation, and problem solving skills.  This was covered on slides 7 -22.  Tomorrow we will finish this by looking at graphical relationships.

Physical Science 20 - Feb 4

Today in class we learned how to name and write formulas for molecular compounds as well as for simple ionic compounds between only 2 elements.  This is a review from grade 10 science.  Remember that molecular compounds occur when you have 2 non-metals and ionic compounds occur when you have a metal and a non-metal.  Students then spent the rest of class working on Assignments C1 and C2.  These 2 assignments will be checked tomorrow.  Tomorrow we will learned about naming and writing formulas for compounds that involve polyatomic ions.

Tuesday 3 February 2015

Physics 30 - Feb 3

Today in class we went over the course outline and then talked about class expectations.  We then did a simple introductory activity that got us thinking about some ideas with motion and measurements in science.  We will take these ideas and apply them to the study of motion.  Students picked up all the handouts for the 1st unit today as well and we will begin this tomorrow.

Physical Science 20 - Feb 3

Welcome to the blog for the course everyone.  Today in class we went over the course outline as well as what you can expect from the class in terms of procedures and such.  After that we got started on chemical nomenclature.  We started with the Nomenclature powerpoint and got all the way to slide on a list of common substances.  Students need to know these common substances and what formulas are associated with these substances.  I have put this list in the chemistry folder of the course notes. It is called Common Substances List.  Please print off and bring to class tomorrow.

Tomorrow we will move on and learn about naming molecular compounds as well as simple ionic compounds
