ap chemistry summer assignment - Cherry Creek School District

WELCOME TO AP CHEMISTRY!!!
School Year 2012-2013
Hi! My name is Ms. Scheffel. I will be your AP Chemistry teacher next school year. As the school year
is coming to an end, I wanted to get out some information about class for next school year. I am
excited to meet all of you and begin another fun year of AP Chemistry. Over the summer I have an
assignment that I would like you to complete. It is a twofold assignment, see below.
I will be at school over the summer if you want to come in and work with me on the assignment. I
also suggest meeting with others that have signed up for the class so you can work on the assignment
together. There will be a quiz the first day of class so please make sure you see me or use your study
guide to get your questions answered.
AP CHEMISTRY SUMMER ASSIGNMENT

ISBN 13: 978-0078928390 (Best place to purchase this study guide is online or from one of my
previous students. If you are unable to purchase the study guide please let me know. I have some
copies for students to borrow.)
b. Buy color highlighters and sticky notes to mark up your study guide.
2. Read and study Chapter 1-3 in study guide. Highlight and uses sticky notes.
a. Bring your highlighted study book and notes. Points will be assigned to you and then the
book will be returned to you for your further enjoyment.
3. Go to school website and printout the summer assignment. (Or you can email me and I will
send it to you.)
a. Email me
b. Make flashcards
c. Complete naming and writing formulas, and simple stoichiometry problems.
Thank you!

Welcome to AP Chemistry! Most of you already have a background in chemistry from your Chemistry or
Honors Chemistry class, but AP Chemistry is very different. Rather than memorizing how to do particular
types of problems, you must really understand the chemistry and be able to apply it to all sorts of different
situations.
It is not all about memorization; however, having these items memorized is essential for success in learning
the concepts covered in the course. Make flashcards, have your friends and family quiz you, take the lists with
you on vacation, or do whatever it takes to get this information firmly planted in your head. Do not wait until
the night before school begins.
NO LATE ASSIGNMENTS WILL BE ACCEPTED!!!
