A lab manual for undergraduate courses in Introductory/Preparatory/Basic Chemistry.
Corwin's best selling lab manual has been used by over 300,000 students. Paying particular attention to the environmental issue, the Fifth Edition retains an effective format of a pre-laboratory assignment, a stepwise procedure, and a post-laboratory assignment. These "bullet-proof" experiments have been used successfully with students in Introductory Chemistry, Preparatory Chemistry, and Allied Health Chemistry. This lab manual can be packaged with any Pearson Intro Prep Chemistry book.

Schweitzer Klassifikation
CHARLES H. CORWIN, educated at San Jose State University, has been perfecting his approach to teaching students chemistry for the past two decades. Through special National Science Foundation funding, he studied creative learning systems early in his career, focusing specifically on the introductory chemistry course. It is from these early seeds that Introductory Chemistry: Concepts & Connections has grown. At present, his active areas of research are web-based chemical education, conceptual and algorithmic learning models, and collaborative learning and group work.
Currently, Charles Corwin is a professor of chemistry at American River College, where he was recognized with a teacher of the year award for innovative teaching in 1994. He was also the recipient of an alumni teaching award from Purdue University in 1998.
