Physical Science B(Monday)
 Bellwork:
    1.  Is it feasible to transfer protons between objects to provide a positive charge?

    2.  What are three ways that charges can be transferred?  Explain.
   
    3.  Based on the results of your lab, what happens when a charged object is brought near a neutral object?      What would happen if the touched?

    4.  Why is plastic used as a coating on the outside of most residential electrical wires?

    5.  How does lightning occur?

Work with your table partner on the sheet that was on the stool by the door.

Finish the electrostatics lab.
Key Concepts to focus on:
        -How to use a pith ball to determine if an object is charged.
        -The difference between conductors and insulators.
        -How to use an electroscope to determine the sign of a charge.
        -How to charge by contact and by induction.

Go over and discuss the material.  Wrap-up and discuss problem areas. Go over any difficult questions from the review sheets.

The lab will be handed in tomorrow before the test.

Practice test.

HW: Study for the test.  Go over the vocabulary and major topics.

Physics B (Monday)

Bellwork:
    1.  How is the current affected by adding bulbs to a series circuit?  Parallel?  Is the same true for     resistance?

    2.  What happens to the potential energy of a positive charge as it is move further from another positive test     charge?

    3.  What has to be done in order to move a charge from a low potential to a higher potential? 

Review major concepts.

Finish the series and parallel circuit lab. 

We will wrap-up most of the material tomorrow.

HW: finish the summary questions for the lab.
