Standards Covered
- 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.
- OGS.2.PS.6Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Investigate and describe the effects of pushes and pulls (applied forces, friction, air resistance, and gravity) on the motion, speed, position, direction, and shape of objects, conducting simple descriptive tests.
- OGS.2.PS.3Open Global Science Standards 2026™ · Science · Level 2 / Grade 1 (Age 6) · Grade 1Investigate and demonstrate how heating and cooling cause reversible changes (melting, freezing, evaporation, condensation) and irreversible changes (cooking an egg, burning, chemical transformations), and explore thermal expansion, contraction, and heat conduction across different materials.
