Standards Covered
- 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.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.7Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Identify and locate external body parts and major internal body systems (skeletal, muscular, digestive, circulatory, respiratory, excretory, nervous, and sensory), describing their primary functions and interactions.
