The 3^rd Edition of General Science is very different from the 2^nd Edition; it is truly a general science course. While the 2^nd Edition spent a great deal of time focusing on the human body, the 3^rd Edition covers a broader variety of sciences that the 2^nd Edition did not, such as astronomy, meteorology, oceanography, general chemistry, general physics, and environmental science. Additionally, the 3^rd Edition is a shorter course, as it only has 14 modules.

With the 3^rd Edition, the Student Notebook is more integrated with the textbook, making it more instructional in regards to note-taking, writing lab reports, and test-taking. Because of these changes, the 3^rd Edition is more of a foundational course as students transition through junior high into high school science courses. We have also added the Video Lessons and Experiments, which provides instruction on each module of the textbook using visual animations and on-location video clips.
