AP Chemistry Summer Assignment
Future AP Chemistry Student,
Welcome to AP Chemistry. I am eagerly anticipating a great year of Chemistry. In
order to ensure the best start for everyone next fall, I have prepared a Summer
Assignment that reviews basic chemistry concepts. There is a multitude of
tremendous chemistry resources available via the Internet. With the ready access
to hundreds of websites either in your home or at the local library, I am confident
that you will have sufficient resources to prepare adequately for the fall semester.
There are a few old chemistry textbooks which can be picked up for your
reference. The reference text book for this course is Chemistry by Zumdahl,
Steven, and Susan Zumdahl. Published by Houghton Mifflin. A suggested study
book that is available for purchase is 5 Steps to a 5 AP Chemistry, 2013-2014
Edition by John Moore and Richard Langley
You may contact me by email: ([email protected]) this summer. I will do my
best to answer your questions ASAP. Taking a college level course in high school
is difficult, requires dedication, and is a great investment in your education so
prepare yourself for the future. Arrive ready to learn!!!
Part 1: Letter of Introduction (20 Points)
Your first digital assignment is to successfully send an email to your favorite AP Chemistry Teacher
by Sunday June 9th following these steps.
a) Use written, full sentences. Do not abbreviate words like you are on the Twitter machine or Myspace with a
friend.
Use spell check!
b) Make the Subject: AP Chem.: Introduction to “ < Insert your name here>”
c) Begin the email with a formal salutation, like “Mr. Edelman,”
d) Now introduce yourself (your name) and tell me a little about yourself like:
What do you like to do (hobbies, sports, music, interests, etc)? Do you have a job? Tell me a little bit about
what is important to you- friends, family, pets, etc. What are your strengths/weaknesses academically?
What is your career goal? Is this your first AP course? Why are you taking this class? What are your study
skills? Etc. Anything interesting?

Utilize Internet Resources to complete the following problems. The URLs below represent a
fraction of the available chemistry addresses available. Please feel free to expand the list
and find other web sites that help prepare you for the coming year. We recommend that
you complete as many online quizzes as possible, take detailed notes, and practice the
items indicated in the packet.
Completed work must be submitted by the appointed dates. Late work will not be
accepted and could result in your removal from the class before school starts. The
goal of these assignments is to give you a basic introduction/review to things that
should be in your Chemistry toolkit when we start.
Let me know if there are any problems in submitting the assignment on time. A list of
books prescribed by the College Board has been provided for your reference. You do
not need all the books to complete the assignment. Any basic chemistry textbook can
help you find the information needed to complete the summer assignment.
