Standards Covered
- OGS.5.ESS.4Open Global Science Standards 2026™ · Science · Level 5 / Grade 4 (Age 9) · Grade 4Analyze environmental factors and human-induced threats to Earth's systems—including atmospheric pollution, the greenhouse effect, acid rain, and ozone layer depletion—and investigate how climate conditions influence community architecture, energy use, and sustainable resource stewardship.
- OGS.5.ESS.1Open Global Science Standards 2026™ · Science · Level 5 / Grade 4 (Age 9) · Grade 4Describe and illustrate the continuous movement of water through the hydrologic cycle (including evaporation, condensation, precipitation, transpiration, surface runoff, and oceanic storage), explaining the Sun as the primary energy source driving these processes and correlating evaporation rates with thermal energy.
