Physical Science A
Bellwork:
    1.  Consider a situation where a person pushes on a car with a force of 2000 N for 85 seconds.  The car     does not move.  How much work and power does the person use?

    2.  In order for work to be done, what must occur?

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.

Check and Go over the homework problems.

Muscle up Lab.  Each group will perform five activities where they will calculate the work done and the power used.

HW: Finish the lab questions.  Read section one and two in the book and answer the questions on page 131.  Quiz wed. over work and power.

Physical Science B
Welcome back after a long weekend!

Bellwork:
    1.  How are the different products separated from petroleum.  What is this process called?

    2.  Currently, how much of our energy is produced using solar energy?  What are some other terms used to     describe solar energy?

    3.  What does the term biomass refer to?

Check and work in groups to compare and check the answers for the homework.  Within each group discuss the answers to what you had found with the homework.  If a person in your group is struggling with the material, take the time to explain and help.  Also, call me over to help too.  By the end of the day, we should have both assignments checked and gone over.  We will hit on key points of each of the renewable resources and I will hand out the review sheet.

Finish renewable resources. 

HW: Review sheet.  We will have a practice test tomorrow and a test on thursday.
