RSO Biology 1 is a year-long, secular homeschool biology curriculum. The unifying concepts found in RSO Biology 1 are the cell theory, the theory of evolution, genetics, and the processes used to define and describe the concept of an organism. RSO Biology 1 begins by explaining the characteristics that non-viral organisms share. Later in the course, anatomy and physiology are taught through the lens of these characteristics. For example, in the chapter covering how all organisms respond to their environment, students explore how those with a nervous system—like people and tardigrades—and those without one—like plants and unicellular microbes—respond to their surroundings. Connections are made, such as when students build side-by-side models of a human nervous system and a tardigrade nervous system, and differences are explained. Age-appropriate math and labs are woven throughout the course, providing students with many opportunities to apply
