B LAYER:  (Choose 2)
o    Planning to take the AP Calculus Examination? Exercises  (see handout)
o    Lab Activity 8 (see handout)
o    Write your Mathematical Autobiography: (Rough Draft due Monday)
I.    Your earliest memories of mathematics or numbers
II.    Your elementary and junior high experiences
III.    Your high school experiences
IV.    Calculator / Computer Experiences
V.    Expectations for this year

A LAYER:  (Choose 1)

o    Absolute Zero is the topic of the example on page 71.  This temperature has never been obtained.  (Rough Draft due Monday)
I.    Summarize how Jacques Charles determined the absolute zero of the Celsius scale.
II.    Find the absolute value of the Fahrenheit scale.
III.    If no one has ever obtained the lowest temperature ever, find the three closest attempts.  (Who? When? Where? typed in newspaper format)

o    Take It to the Limit  (Rough Draft due Monday)
While limits are a fundamental concept in calculus, the idea of a limit can be found elsewhere.  Music, visual arts, advertising, and other areas of popular culture often use the concept.  Find an example of a song, poem, picture, or other item and explain how it uses or demonstrates the concept of a limit.

o    Archimedes is often given credit for discovering Pi (3.14).  Research how he used limits to find the value of Pi.  (Rough Draft due Monday)
I.    Who is Archimedes? (Who? When? Where?)
II.    How did he find the value of Pi?  Include several diagrams with your explanation. 
III.    How is this method related to a limit?
