Organize

  1. Prepare for lecture by reading the assigned sections from Chapter 3 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.
  2. Take the Diagnostic Quiz and work the Concept Test questions in your textbook to assess your understanding of basic concepts. Examine the diagnostic quiz feedback, review textbook sections that correspond to questions you missed, and be prepared to ask questions about any material you do not understand.
  3. Use the Flashcards to test your memory for new vocabulary terms.

Learn

  1. Re-read Chapter 3 in your textbook (or ebook) and review your lecture notes. 
  2. Work through the ChemTours for this chapter. ChemTours use animation and interactive exercises to develop your understanding of fundamental topics.
