Physics
Bellwork:
    1.  What is meant when we say frame of reference?  Feel free to look it because I want to discuss this          topic.

Objectives:
    -Be able to describe the motion of an object in terms of its displacement, speed, and velocity. 
    -Be able to explain the difference between speed and velocity.
    -Be able to explain the difference between distance traveled and displacement.

Go over the homework, discuss any problems where you may have had trouble.

Note/discuss motion, speed, and velocity, formula for acceleration.

Motion Lab: Students will compete against each other is 5 difference races.  The average speed for each student will be determined for each race.

HW: Speed, Velocity, and Acceleration Problems.




Physical Science

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 vitamin supplements along with the grass/grain     they normally eat.  In the end of the experiment, the cows give 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 unit 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.
