key vocabulary:

  • aphelion: the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
  • perihelion: the point in the orbit of a planet, asteroid, or comet at which it is closest to the sun.
  • astronomical units (AU): unit of length, roughly the distance from Earth to the Sun and equal to about 150 million kilometres. The actual distance varies as Earth orbits the Sun, from a maximum to a minimum and back again once each year
  • solar longitude (Ls):  the ecliptic longitude of the sun; describes the position of the earth in its orbit, being zero at the moment of the vernal equinox.
  • ionosophere: charged regions that exist within the upper atmospheres of planets, moons, and minor bodies of the Solar and other Stellar Systems.

Potential Math Content: line graphs, trigonometric functions, curves, comparing units, developing theories about why (e.g. length of seasons)

Potential Content Connections: astrophysics, space physics, cycles
