Standards Covered
- OGS.9.LS.5Open Global Science Standards 2026™ · Science · Level 9 / Grade 8 (Age 13) · Grade 8Compare sexual and asexual reproductive strategies across organisms, evaluating their impacts on genetic variation, human reproductive biology including the menstrual cycle, population dynamics, contraception, and sexually transmitted infection prevention.
- OGS.9.LS.2Open Global Science Standards 2026™ · Science · Level 9 / Grade 8 (Age 13) · Grade 8Analyze the hierarchical organization of multicellular organisms from cells to organ systems, evaluating how integrated human systems (circulatory, respiratory, nervous, digestive, endocrine, immune, and reproductive) and plant vascular structures sustain organismal survival.
