Integrated Science

An “integrated science” course serves the purpose of a “general science” course covering both the physical and life sciences. These courses are “integrated” in that the fields of science are not compartmentalized. For example, in describing the physics of light, we show how this applies to the inner workings of our eyes, which, in turn, are sensitive to visible light in great part because of the chemical composition of our atmosphere. Our high school and jr. high integrated science courses each cover the same material. The high school level course, described below, is more intensive with longer lessons as well as more rigorous unit exams. You should know that this particular full version course is the most comprehensive of all our courses including biology lessons. At a high school pace, this course is reasonably extended over a two year period for a full two years of high school science credit. Year one: physics and chemistry. Year two: biology, earth science, and astronomy. Listed on a separate page we also have our lower level integrated science “explorations” course appropriate for the middle school student (Grades 7 – 9).

Homeschool Planet automated planners are now available for this integrated science course. You’ll find a planner specific to the second edition textbook and another specific to the third edition textbook (shown below).

This upper level self-study course collates all 29 chapters of the Conceptual Integrated Science textbook into 5 units and a total of 29 modules (one module per chapter). This course, adapted from a college level curriculum, provides a strong and enjoyable introduction to integrated science for the high school student when space over two years.  Recommended for grade levels 9 and higher. As with all our courses, performance on our automated quizzes is tracked through a student grade book. Video tutorials and reading assignments are complemented by study advice from the authors, worksheets, interactive simulations, homework assignments, automated quizzes, and unit exams. Included are full suite of lab activities that can be performed using materials available within your household or a local discount store. This course serves well as a precursor to our Conceptual Physics or Conceptual Chemistry courses, which provide greater depth on a broader range of topics.

“Most of the scientific questions you’re curious about, or need to know, involve not just one discipline, but several of them in an overlapping way. What is the nature of the universe? That’s astronomy + physics. How are our bodies altered by the foods we eat? That’s chemistry + biology. What of our climate? That’s all of the above: physics, chemistry, biology, and Earth science!”
