I taught at Truman for over thirty years. I have left my position at Truman but I've left these resources available to any students that need them. I don't know how long I will continue this website but for now please enjoy the many materials I have collected over the years.

Required Course Materials


bookcoverIntroductory Chemistry Essentials 5th. Ed. by Nivaldo J. Tro (Pub. Pearson)

(optional)Mastering Chemistry: instructions for enrolling

Laboratory Notebook

laboratory notebook

No specific brand is required but the pages MUST BE BOUND. Spiral notebooks may NOT be used. I prefer quad rule pages (graph paper) but any kind of pages are fine - blank, lined etc. It is important to have a firmly bound book for keeping a permanent record of laboratory observations, data, summaries, analyses and reflections. The laboratory notebook should not have perforated pages that can be removed. View Sample Pages

Note: There is no laboratory textbook to purchase for this class but you will need to print laboratory assignments from the Internet.


You will need a calculator and should bring it with you to every class. It should be able to use scientific notation.
