Earth and Space Science


Cycles and Patterns of Earth

and the Moon

  1. The hydrologic cycle illustrates the changing states of water as it moves through the lithosphere, biosphere, hydrosphere and atmosphere.

  2. Thermal-energy transfers in the ocean and the atmosphere contribute to the formation of currents, which influence global climate patterns.

  3. The atmosphere has different properties at different elevations and contains a mixture of gases that cycle through the lithosphere, biosphere, hydrosphere and atmosphere.

  4. The relative patterns of motion and positions of the Earth, moon and sun cause solar and lunar eclipses, tides and phases of the moon.




Physical Science


Conservation of Mass and Energy  


  1. The properties of matter are determined by the arrangement of atoms.

  2. Energy can be transformed from one form to another or can be transferred from one location to another, but is never lost.

  3. Energy can be transferred through a variety of ways.






Life Science


Cycles of Matter and Flow of Energy

  1. Matter is transferred continuously between one organism to another and between organisms and their physical environments.

  2. In any particular biome, the number, growth and survival of organisms and populations depend on biotic and abiotic factors.
