The second edition of thisĀ general science course has several features that enhance the value of the course:

  • Scientific advances in the relevant topics have altered how some of the material is covered. For example, the primary function of the human appendix wasn’t determined until 2006. Thus, while the primary function of the appendix is not discussed in the first edition, it is discussed in this edition.
  • There is more color in this edition as compared to the previous edition, and many of the drawings that are in the first edition have been replaced by higher-quality drawings.
  • Advanced students who have the time and ability for additional learning are directed to online resources that give them access to advanced subject matter.
  • To aid the student in reviewing the course as a whole, there is an appendix that contains a Summary of the Module which covers the entire course. The solutions and tests manual has the answers to those questions.


Because of the differences between the first and second editions, students in a group setting cannot use both. They must all have the same edition.
