The 2 books in this set include the Student Textbook and Solutions and Test Manual for Exploring Creation with Physical Science. This course is designed to be the last science course the student takes before high school biology. Thus, we generally recommend it as an 8th grade course. However, your student can also use it for their 9th grade course work. The text discusses such topics as the atmosphere, the hydrosphere, weather, the structure of the earth, environmentalism, the physics of motion, Newton"s Laws, gravity, and astrophysics.
