Physical Science B
Bellwork:
    1.  Find the number of protons, neutrons, electrons for the following elements:
   
            a.    30  Mg
                        18

           
            b.    107 Ag
                         47

    2.  Whenever charges are moving for either an electrical discharge or flowing current, what type of charge is     responsible? 

Objective:
    Be able to explain Coulomb's Law.  Basically, explain how the force between charges relates to the size of the     charge and distance between the charges.

Quiz: Atomic Number Quiz

Please take out your electric field homework.  We will check and go over the homework on the whiteboards

When finished we will use the computer model to look at Coulomb's Law.

HW:  Activity, computer air hockey.  Use concepts of interacting charges and the forces between the charges to complete the activity.

Physics B

Test today over electrostatics.

When finished please read Chapter 21, and answer the questions on pages 565 (1-5), and 568 (11-15)
