Free High School Science Texts

The Free High School Science Texts (FHSST) organization is a South African non-profit project, which creates open textbooks on scientific subjects. Textbooks are edited to follow the government's syllabus, and published under a Creative Commons license (CC BY ), allowing teachers and students to print them or share them digitally.

History
FHSST was conceived in 2002 by Mark Horner, a physicist, when some rural South African children asked him to proofread notes that they had taken on a talk he gave on wave phenomena. The children intended to take the notes back to their schoolmates to use as a textbook on the subject.

Subjects
FHSST has released books for grades 10-12 on physics, chemistry and mathematics. They are developing books in life sciences and computer literacy and a guide to teach students how to study.
