This site houses various curricular options from different publishers covering all subjects with almost all science curricula containing evolutionary content. (Secular, K-12, homeschool)
GSN houses seven different online curricular options in all core subjects as well as electives. Most options are for middle and high school and one of the seven options is labeled as “Christian”. With regard to science content, all of their science curricula include evolutionary content except the “Christian” option, which is described as coming from a “creationist” perspective. They also have several Honors/AP science courses available. A drawback of their materials may be that they can only be purchased as a complete annual curriculum on all subjects, meaning that families pay a licensing fee from that publisher and then are committed to using their curricula for all subjects during that academic year. Currently the licensing fee is about $450 per student per year.
