Standards Covered
- OGS.2.LS.2Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Identify and examine the main structures of plants (roots, stems, leaves, flowers, fruits, and seeds), explaining how each part helps the plant absorb water and nutrients, transport materials, make food via light, and reproduce.
- OGS.2.LS.4Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Observe, document, and describe life cycles of plants and animals (including germination, growth, maturation, reproduction, and parental care in insects, fish, amphibians, reptiles, birds, mammals, and humans), noting developmental changes and similarities between offspring and parents.
- OGS.2.LS.5Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Investigate habitats and ecological relationships, modeling food chains to show how energy flows from the Sun through producers and consumers, and describing interactions between living and nonliving components in terrestrial and aquatic ecosystems.
- OGS.2.LS.8Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Demonstrate understanding of essential personal hygiene, nutrition, balanced diet, physical exercise, rest, sensory organ protection (sight and hearing), disease prevention, and safe habits to maintain health and well-being.
