Physical Science B

Bellwork:
    1.  Draw the fields around two proton brought near each other.

    2.  Based on the activity done on friday, what factors affect the force experienced between charges?      Discuss this with the person next to you.  There should be at least three factors that can be listed.

Objectives:
    1.  Understand how charges interact with each other.
    2.  Be able to identify the direction of the electric field around protons and electrons.  Also, draw the     field around two interacting charges.
    3.  Explain how charges are transferred between objects.

Discuss the results of the activity from Friday.  Go over Coulomb's Law.

Go over and check the prelab.

Electrostatics Lab

HW:  Finish the vocab terms tonight.  We will a short test/quiz over electrostatics on Thursday.

Physical Science A
Bellwork:
    1.  What are the base units of the metric system?
    2.  What are the prefixes for the metric system?
    3.  Consider an experiment where cows are given a vitamin supplement along with the     grass/grain     they normally eat.  In the end of the experiment, the cows given the supplements     were overwhelmingly healthier and larger than the untreated group.  Identify the control     group, independent variable, and the dependent variable for this experiment.

Goals:
    -Understand the difference between metric units and english units. 
    -Be able to convert units in the metric system.
    -Be able to measure and convert units of the metric system.

Today we will discuss the Metric vs. English systems of measurement. 

Discuss unit conversions and go over/check the homework.

Measure Activity: Students will measure distances around the room. They will focus on using metric units.  Lastly, they will convert the units they measured.

HW:  Finish the unit conversions for the measuring activity.  We will have a quiz tomorrow over the scientific method, experimental design, and the metric system(SO, be sure to study, there is NO excuse!)
