Physical Science A
Check Vocabulary and binders.

Bellwork:
    1.  If you are about to take a vacation and your parents want you to determine the average speed your     family will travel throughout your trip, how would you explain to them the method to do so? 

    2.  If you had to explain the concept of speed to someone right now, what would you say?

Goals: 
    -Be able to understand how speed and velocity are calculated.
    -Be able to explain the difference between speed and velocity. 
    -Be able to calculate the speed of an object using measure values.

Discuss speed, displacement, and velocity.

Speed lab:  Students will determine their average speed for races they perform in class.

HW:   Finish lab questions.  Watch the video on how to graph the speed of an object.

Physical Science B
 Bellwork:
    1.  Explain where protons, neutrons, and electrons are found in an atom.

    2.  If an element has a mass number of 56 and an atomic number of 12.  What is the number of protons     neutrons and electrons.
   
    3.  From your lab, explain how an object can become negatively charged?  Positively charged?

    4.  Use your knowledge of what you have done in the lab thus far and explain the difference between a     conductor and an insulator.


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.

You should be able to explain these things when finished.

HW:  When done, answer the analysis/summary questions.  They will be collected tomorrow. Finish the vocabulary for the electrostatics unit. Test on Friday!
