Science for High School was developed by a homeschool mother of 5 to keep interest in science alive in high schoolers. Because a homeschooling mom wrote the program, it has a lot of features that she longed for in a program: all the answers necessary on one place!
The science manuals lead the student in exploring a particular topic of science, a search to discover on their own. They have a research topic/question. To answer it, they read a lot of material then process the information and put their answers into their own words. This part is important because this processing leads to understanding. Where understanding is, memorization is not necessary.
This program offers Physical Science, Biology, and Chemistry. Physics is in the works!
