Physics 30 - April 7

Today students learned about potential energy and how to calculate it.  The concept of defining a reference level is important in understanding potential energy.  Students were given Assignment 3.4 to work on. Tomorrow we will begin to look at the law of conservation of energy and how to work with it.

Physical Science 20 - April 6

Today we finished up our notes on kinetic molecular theory.  We did slides 11-25 on the powerpoint from yesterday.  There was no assignment with today's lesson but students spent the remainder of the class period working on their lab reports for Lab C4.  This is due Friday.

Physics 30 - April 6

Today we looked at the concept of energy and learned how to calculate kinetic energy.  We also learned how to about the work-energy theorem, where you can calculate the work done by figuring out the change in kinetic energy.  This was covered on slides 15-23.  Assignment 3.3 was given at the end of class. We will go over this on tomorrow and then learn about potential energy.

Physical Science 20 - April 5

Today students finished up Lab C4 by measuring the mass of the silver they produced as well as the mass of copper remaining.  After cleaning up the lab, we started into our new unit on heat.  This will not take us too long to finish.  We began by looking at what heat is and discussing some major points to kinetic molecular theory.  This was all covered on a powerpoint called Kinetic Molecular Theory.  This powerpoint is in the Heat folder of the Physical Science 20 course notes link.  We only covered the first 10 slides today in class.  Tomorrow we will finish the powerpoint.

Physics 30 - April 5

Today in class we talked about power and how to calculate it.  We went through a coukle of examples covered on slides 10-14 and students had the remainder of the period to work on Assignment 3.2.  This will be due tomorrow.  Tomorrow we will move one to look at energy and specifically kinetic energy.

Physical Science 20 - April 4

Welcome back everyone.  We had a whole 10 days for our reactions to setup.  This worked well for us as we did the 2nd part to Lab C4 today.  Students were extracting silver today from their reactions.  We spent all day working on the lab and extracting the silver.  Tomorrow we will finish up the lab and start into the heat unit.

Physics 30 - April 4

Welcome back from the break everyone.  Hope it was restful and relaxing and you are ready to drive to the summer.  We only have about 10 weeks of school left so get ready.  Today we started the third unit in Physics 30.  We began looking at the physical definition of work and what work is.  We did examples 1-3 and looked at some special situations where work is zero.  Students then had the remainder of class to work on Assignment 3.1. We will take this up tomorrow.  We are moving on tomorrow to look at the concept of power.
