This is a very comprehensive, systematic, quality curriculum with an excellent scope and sequence. Materials are developed with increasing depth at each grade. All major science topics are introduced in grades 1-6 and then developed in detail in grades 7-12. Each course includes a variety of hands-on, science skill-building activities or labs. Materials for grades 1-6 include student text, teacher edition, teacher packet, student notebook, tests, and answer key. Materials for grades 7-12 include student text, teacher text, student lab book, teacher lab book, tests, and answer keys. We highly recommend Bob Jones for grades 1-6 in order to lay a solid foundation for the higher grades. It is also appropriate in grades 7-12 for parents with a strong science background or if you have children who excel at science and are interested in pursuing a scientific area of study in college.

Weaknesses are high amount of teacher preparation time, excessive content in the upper level courses, and high lab cost. This curriculum was designed for teaching in school classrooms, making the lessons and labs more challenging to do in a homeschool setting.
