This course is designed to be a student's first systematic introduction to the sciences. The course covers topics like the history of science, scientific method, designing experiments, simple machines, archaeology, geology, paleontology, biology, and human anatomy and physiology. Therefore, its scope is quite wide. There are many hands-on experiments to do, and they all use household items. The second edition of our 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color in this edition as compared to the previous edition, and many of the drawings that are in the first edition have been replaced by higher-quality drawings.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.
