Standards Covered
- OGS.5.ESS.2Open Global Science Standards 2026™ · Science · Level 5 / Grade 4 (Age 9) · Grade 4Describe the physical characteristics of Earth and its atmosphere, and examine the geological and hydrological forces shaping the planet's surface—including tectonic plate movements, landform relief changes, ocean currents, and tidal dynamics.
- OGS.5.ESS.3Open Global Science Standards 2026™ · Science · Level 5 / Grade 4 (Age 9) · Grade 4Collect and analyze observational data to identify predictable astronomical patterns—including seasonal changes in daylight length and temperature resulting from Earth's orbital translation and axial tilt, observable lunar phases, the relative scale and positions of planets in the Solar System, and the distinction between mass and gravitational weight on different celestial bodies.
