Physical Science B

Welcome Back!

Collect Syllabus Signed Back Sheets

Check and discuss homework from friday.

Short Reading Quiz

Begin Electrostatics. 

Discuss Atomic Structure.

Objectives:
    1.  Understand the general structure of an atom.

    2.  Be able to identify the number of proton, electrons, and neutrons for a given atom using the atomic number     and mass number.

Atomic number worksheet.

HW: Finish the Atomic Number Worksheet.

Physics B

Pick-up the pre-lab and work on the this individually.

While working on the pre-lab, I will check the your homework, the section 1 and 2 review questions.  When finish we will go over the pre-lab.

Discuss briefly the basics of electrostatics. 

Explain the electrostatics lab.     
    -you will work in groups on 3 for the lab.
    -make sure that you do not proceed until you have gotten my signatures at the check point. 
    -as you work through the lab, you should be making observations and taking notes over the following     concepts:
            -how to determine if charge is present
            -what are the types of interactions that result with the interaction of charges
            -difference between a conductor and an insulator
            -charging by contact and induction
            -polarization of charges

As you move through the lab, if you hit a point where the concepts don't make sense, stop and ask!

HW: begin to work on the "Coulomb's Law Problems".  These are not due tomorrow but will be due on thursday.
You will have a short test over electrostatics on Friday.
