Physics 30 - Feb 29

Today we started our second unit on dynamics.  We learned what forces are, general types of forces as well as some of the specific forces that we will be studying.  We also learned what a net force is as well as how to determine the net force.  A new type of diagram was introduced which was the free body diagram.  The FBD for short, will be a vital component to solving problems involving forces.  Assignment 2.1 was assigned and we will take up this assignment on Wednesday.  This was all covered on slides 1-15 on the new powerpoint in the Unit 2 folder.

Happy Leap Day Everyone!!  It also happens to be the day that we started to learn about the mole.  We had some time to go over the assignment from Friday on metric conversions but then moved on to learn about what the mole is.  This was covered in a new powerpoint called The Mole.pptx found in the notes folder of the chemistry folder in the Physical Science 20 Course notes link on the right hand side of the webpage.  We covered slides 1-12 today and students spent most of the class working on Assignment C17, which we will go over tomorrow.  Tomorrow in class we will learn how to use the molar mass to convert between mass of a substance and moles of a substance.

Today we finished our notes on math and the math skills we will need moving forward with Physical Science.  This included learning about how to using significant figures in calculations, scientific notation and how to do unit conversions.  The unit conversion part was particularly important as it serves as a basis for the remainder of the chemistry in this course.  Students learned a method for unit conversion called dimensional analysis.  The notes were covered on slides 16-49 but the dimensional anaylsis section was just on slides 36-49.  Students then spent the remainder of class working on this assignment.  They did the even questions.  We will take it up on Monday.  Have a great weekend everyone!

Physics 30 - Feb 25

Students had a work period today in class to prepare for the in class assignment tomorrow.  Students mostly worked on Assignment 1.7 but need to know all assignments in this unit to be ready for the assignment tomorrow.  Good luck!!!

Physical Science 20 - Feb 25

Today  we started to review math skills important for science.  This included a discussion about significant figures and scientific notation.  Tomorrow we will finish this will a discussion on unit conversion.  This is all located in a new powerpoint called Math Notes located in the Chemistry folder of the course notes link. We covered Slides 1-16 today. Tomorrow we will cover the rest.  

Students also handed in Assignment C16 today.  I will mark them and return them to the students in due time. 

Physical Science 20 - Feb 24

Hello everyone.  Welcome back from the Feb break. Sorry for my extended absence.  It has taken me a couple of days to get back up to speed with everything and I just haven't been able to post anything for a couple of days.  On Monday and Tuesday of this week, we learned about double replacement reactions and how they occur.We also learned how to determine whether or not an ionic compound would be soluble.  This led to some new types of equations called ionic equations.  At the end of the class on Tuesday, students worked on Assignment C15.  The notes were covered on slides 54-73 in the Chemical Reaction Powerpoint.  Today students wrote the Nomenclature quiz and then worked on Assignment C16.  This assignment is a review of all the reaction stuff we have been learning .  It is the second hand in assignment that I will be collecting tomorrow. Tomorrow we will have a change in pace and start learning about some math skills that we will need moving forward.

Physics 30 - Feb 12

Today we looked at the bulletin board project again and looked at some good projects and others.  Students are asked to think about their topics over the break and have a list ready for Monday.  I will be taking topics in after the break.  After this, students learned how to draw a scale diagram when working with vectors.  This was covered in Example 9 in the notes.  We finished up this example up with a couple of minutes left in class.  Students were assigned Assignment 1.5 and were to have it done over the break.  Have a great break everyone!!
