As of 2015, Common Core stipulates that seventh grade life science cover the basic characteristics of biological life forms, as well as basic principles of natural selection and genetics. Many websites offer sample resources and lesson plans explicating these topics for teachers.
Seventh grade life science under the Common Core serves as an introduction to basic biological concepts, such as genetic variation and heredity. In particular, seventh grade life science covers the key characteristics distinguishing life from non-life; basic cell anatomy and the similarities and differences between animal and plant cells; the organizational hierarchy of cell, tissue, and organ; and basic functions of the various human organ systems.
Seventh grade life science also covers genetics and natural selection in a simplified way, teaching students how sexual reproduction produces greater variation than asexual reproduction, patterns of hereditary, and how environmental pressures and lifestyle choices affect genetic populations.
