7.ESS.1: The hydrologic cycle illustrates the changing states of water as it moves through the lithosphere, biosphere, hydrosphere and atmosphere.
7.ESS.2: Thermal-energy transfers in the ocean and the atmosphere contribute to the formation of currents, which influence global climate patterns.
7.ESS.3: The atmosphere has different properties at different elevations and contains a mixture of gases that cycle through the lithosphere, biosphere, hydrosphere and atmosphere.
7.ESS.4: The relative patterns of motion and positions of Earth, moon and sun cause solar and lunar eclipses, tides and phases of the moon.
7.ESS.5: The relative positions of Earth and the sun cause patterns we call seasons.
7.PS.1: Elements can be organized by properties.
7.PS.2: Matter can be separated or changed, but in a closed system, the number and types of atoms remains constant.
7.PS.3: Energy can be transformed or transferred but is never lost.
7.PS.4: Energy can be transferred through a variety of ways.
Energy flows and matter is transferred continuously from one organism to another and between organisms and their physical environments.
7.LS.2: In any particular biome, the number, growth and survival of organisms and populations depend on biotic and abiotic factors.
