Physical Science A
We will finish the muscle up lab.  Be sure to check your calculations, answer the questions at the end. 

Explain the inclined plane problem.  Show how to set up the track.  Investigate which scenario requires more work.  When finished answer the questions.

Objectives:
    1. Compare work done in different situations.  Give two examples of work being done and   
            compare the magnitude of the work in each situation. 

    2. Explain why work has a more precise scientific meaning than the meaning of work in everyday     language.

    3. Calculate the amount of work done on an object that is moved from one position to another.      Use     the formula W=Fd to solve for the work done by an object.

HW: Section two review questions, Answer the questions on both activities(muscle up and inclined plane).

Bonus Work: You can pick up the additional problems for work and power.  Also, begin working through the chapter review at the end. 

Physical Science B

Bellwork:
    1.  Let's go over the review sheet and discuss any problem questions that you may have had.

    2.  Read and discuss article.



Practice test.

When everyone has finished the practice test, we will go over the answers and touch on a few key points.

HW:  Study for the test.  Test is tomorrow.
