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 the local library, I am confident that you will have sufficient resources to prepare adequately for the fall semester. The reference textbook for this course is Chemistry: The Central Science, 10th edition, Brown, LeMay and Bursten, Prentice-Hall, 2006. Additional Online General Chemistry Sites: http://chemteam.info/ChemTeamIndex.html www.chemfiesta.com www.chemistrygeek.com http://www.collegeboard.com/ap/students/chemistry/index.html www.chemmybear.com You may contact me by email: bgreyson@sdb.k12.wi.us this summer. I will do my best to answer your questions ASAP. You can also follow me on Twitter @BarbGreyson for occasional updates and for reminders about the two Pizza Hut work sessions. AP Chemistry is an equivalent course to Introductory Chemistry in college. Taking a college level course in high school is difficult, requires dedication, and is a great investment in your education to prepare yourself for the future. Arrive ready to learn! Assignment 1: Letter of Introduction (10 points) Due date: Friday, June 27 Your first digital assignment is to successfully send an email to your AP Chemistry teacher. Draft an email following these rules: a. Use written, full sentences. Do not abbreviate words like you are on the Twitter with a friend. b. Use spell check. c. Make the Subject: AP Chem.: Introduction to “<Insert you name here>” d. Begin the email with a formal salutation, like “Mrs. Greyson,” e. 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?
