AP CHEMISTRY SUMMER ASSIGNMENT 2013
Flowing Wells High School
The AP Chemistry course is designed to be the equivalent of the general chemistry course
usually taken during the first college year. It is an extension of either Pre AP or Chem 1-2 you
have had in the past and will be adding a significant amount of content and knowledge to your
understanding of the subject.
Because AP Chemistry serves as a general chemistry course taken in college, a good
understanding of the topics discussed in Pre AP/ Chem. 1-2 is essential. To prepare for the
rigors of this course, you will be required to complete the worksheet which summarizes many of
the important topics of your previous chemistry class. Expect a quiz in the beginning of the
year school-year!

Focus on chapter 1-3
ASSIGNMENT:
 Complete the assigned work on the next pages.
 These problems will be checked for completion on the first day of school.
 A quiz on this material will be given by the end of the second week.
 This assignment should take you approximately 3-4 hours to complete depending how
readily recourses are available.
Best of luck and cannot wait to see you next year!
