In high school (grades 9-12), students will continue focusing on biology, chemistry, physics, and earth science each year. Families may choose to explore a different topic each day of the week or study biology one day a week and one other subject on three additional days. Either way, students will complete 33 lessons in each subject yearly. Three terms’-worth of material in each category equals a science lab credit for transcripts.

Credit Value

A one-year course (1 credit) is achieved upon the completion of three study guides from a single subject. For example:

Transcript Credit ComponentsYour choice of three of the following:
Biology (with Lab)F3-4 Biology
F3-4 Botany
HS Biology: Anatomy, Part 1
HS Biology: Anatomy, Part 2
HS Biology: Ecology
HS Biology: Human Body (extra options)
HS Biology: Microbiology, Biochemistry, & Forensics (extra options)
HS Biology: Origins
Chemistry (with Lab)F3-4 Chemistry
HS Chemistry: Part 1
HS Chemistry: Part 2
HS Chemistry: Part 3
Physics (with Lab)F3-4 Physics
F3-4 Electronics
HS Physics: Part 1
HS Physics: Part 2
HS Physics: Part 3 OR Earth Science: Astrophysics
HS Physics: Theoretical Physics (optional)
Earth Science (with Lab)F3-4 Geology
HS Earth Science: Geology
F3-4 Weather
HS Earth Science: Weather
F3-4 Astronomy
HS Physics: Part 3 OR Earth Science: Astrophysics

Credit can be assigned as follows:

  1. You can assign partial credit (.33) each year for each subject to show that a one-year course took longer than one year to complete.
  2. You can assign the one-year course credit (1) upon completion of the course, no matter how long the material took to complete.
  3. Alternatively, you can assign one-year course credit (1) in a single subject each year. For example 9th grade Biology, 10th grade Chemistry, 11th grade Physics, 12th grade Earth Science. This is the most straightforward way, but not as precise.

Requirements vs. Recommendations

It will be beneficial to research your state’s graduation requirements or the requirements of the prospective colleges your child may want to attend.

While even college-bound students are only required to take 3 courses with a lab, Charlotte Mason included science as part of the broad feast all four years. Therefore, she assigned science four to five days a week all the way through high school. If we follow her lead, students will complete lab credits in all four science disciplines.
