Standards Covered
- OGS.2.PS.1Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Observe, classify, and compare everyday objects and substances by their observable physical properties (shape, color, texture, flexibility, hardness, transparency, density, buoyancy, and relative weight or size), and differentiate between natural materials and human-made objects.
- OGS.2.PS.9Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Explore light sources, straight-line propagation, shadow formation, reflection from polished surfaces, and transmission through transparent, translucent, and opaque materials, including the behavior of lenses, prisms, and mirrors.
- OGS.2.PS.2Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Investigate the properties of air and water (including volume, mass, air pressure, buoyancy, and surface tension), observing that air takes up space and creates resistance, and that water exists in multiple states with distinct physical behaviors.
