Physics 30 - March 4

Today in class we learned about Newton's Third Law of Motion, or the action-reaction law.  We learned about the implications of such an important law and how often we use this law and don't realize it.  I assigned Assignment 3.3 at the end of the class.

Physical Science 20 - March 4

Today in class we went through the process for how to write a formal lab report.  Students will need to follow this process for every formal lab we do.  Students then got the remainder of the period to write the report for the lab we did yesterday and they handed the report in at the end of the period.  If they finished before the end of the period, they then had to work on Assignments C18 and C19.  These assignments will serve the basis for the Mole Quiz next Tuesday.  Have a great weekend everyone.

Physics 30 - March 3

Today in class, 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 and then had time to work on Assignment 2.2.  This was covered on slides 22-31 in the Unit 2 Notes powerpoint. Tomorrow we will finish Newton's Laws of Motion by learning about the 3rd law of motion.

Today in class we went over them Assignment C18 and C19.  The answers are posted in the answer key folder in the course notes link.  Most students were not finished doing these assignments.  They should have them completed by next Tuesday as these assignments will serve the basis for the quiz that day.  Students then had a chance to do the first lab of the year.  This was called Lab C2 - The Art of Chemistry.  If students were absent today, there is a set of sample data in the Chemistry folder.  It is called Lab C2 Sample Data.  Use that to complete the lab report.

Physical Science 20 - March 2

Today students had a period to work on Assignments C18 and C18.  We will go over the answers to them tomorrow.

Physics 30 - March 1

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.  Reminder that tomorrow is our first unit exam.  Please remember to bring a calculator, pencil and eraser.  I will provide the formula sheet

Physical Science 20 - March 1

Today in class we began to look at how to convert information using the idea of the mole.  This involved using the molar mass to convert from the mass of a substance to moles of the substance and visa versa.  As well, we can use Avogadro's number to convert from the number of particles of a substance to the moles of the substance and visa versa.  We then did an example where we converted to the number of molecules given the mass of a substance in grams.  We also learned how to find the mass of a certain number of atoms of the substance.  These two examples 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 Assignments C18 & C19. This was all covered on slides 16 - 19 in the powerpoint called The Mole.  Students were assigned Assignments C18 and C19 but we will get some more time tomorrow to work on this.
