Physical Science 20 - Feb 2

Happy Groundhog day everyone!  Even though we have 6 more weeks of winter ahead of us, that doesn't mean we can stop learning.  Today we went over Homework C1 and C2.  The answers are posted in the Answer Key folder of the chemistry unit in the Physical Science 20 Notes link along the right hand side of the webpage.  We learned today how to name compounds involving ions that have multiple charge as well as compounds that involve polyatomic ions.  This was covered on slides 43-60 of the Nomenclature Notes powerpoint from yesterday.  At the end of class, students had time to work on Homework C3 and C4.  We will take this up tomorrow and then work on naming acids and hydrated compounds.

Physics 30 - Feb 1

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.  Students can start Assignment 1.1 at home.  I am not able to hand out textbooks yet however I do have the textbook online.  It can be found here.  Use this at home until we can get the physical version of the text.

Physical Science 20 - Feb 1

Hello everyone!  Yesterday we spent our time getting through the course outline and discussing classroom expectations.  Today we started into chemical nomenclature.  This is a review of Science 10 and the concepts you should have learned in Science 10.  We learned how to name elements, covalent compounds and even simple, binary ionic compounds.  This information was all covered on slides 1-42 in the powerpoint labelled Nomenclature Notes.  Students followed along with the handout I gave them today in class and just filled in the blanks from the powerpoint.  At the end of the class I assigned Homework C1 and Homework C2.  We will go over these tomorrow.  Tomorrow we will look at ionic compounds where the ions can have multiple cationic charges as well as compounds that involve polyatomic ions.

Physics High School Exam Competition

Today in class I mentioned about 2 exams that students can write in the spring.  These exams review the content covered in all physics classes in high school.  They award scholarships to be put toward physics classes in university.  For more information on these exams, please go to the following website - High School Physics Exam Competition.

If students are willing to write either or both of the exams, please let me know.  In the spring(March or April), I will need to order the correct amount of exams.

Physical Science 20 - Sept 28

Today, we did another example related to molar conversions.  We did an example where we found the mass of a certain number of atoms of the substance.  This example involved 2 steps, first converting our given information into moles and then converting from moles into the required.  Students then had a chance to work on Assignment C18. We will take this up tomorrow.  We will also do our first lab tomorrow on the mole.

Physics 30 - Sept 28

Today students began class by writing the quiz for Lab 1.1.  This took the majority of class.  Afterwards, students learned about Newton's Second Law of Motion.  We went through a couple of examples that outline the relationships that exist between mass, force and acceleration.  This was covered on slides 22-31 in the Unit 2 Notes powerpoint. We didn't quite finish the notes today.  We will finish them tomorrow and then get a chance to work on Assignment 2.2.

Physics 30 - Sept 27

We learned about Newton's First Law of Motion today, or the Law of Inertia.   After students took a couple of slides of notes (slides 16-17) we then looked at many different examples of inertia as well as a couple of interesting demonstrations of the first law.  There was no assignment that went along with this lesson.  Students can work on Assignment 2.1.
