Summer Assignment AP Chemistry
Name ___________________________
Reading Assignment: The Disappearing Spoon, by Sam Kean.
Write a thorough synopsis of Chapter 4: Where Atoms Come From: “We Are All Star
Stuff” and another chapter you find particularly interesting. This additional chapter
should not be Chapter 1. Your synopsis should be typed and use good conventions
of writing including grammar, punctuation, and spelling.
In addition, please complete solve the following problems to sharpen your skills this
summer. If you have questions, please contact Ms. Polewski at [email protected]
Your synopsis and problem sheets are due the first day of class.
