Read through all of the background information prior to doing the simulations

The NAAP Basic Coordinates and Seasons Lab covers three different, but related areas. Terrestrial coordinates and the celestial equatorial coordinate system are covered and are used to explore the motion of the sun and how it relates to seasons.

Basic Coordinates and Seasons Student Guide (pdf)

Terrestrial Coordinates

• Units of longitude and latitude
• Finding longitude and latitude
• A bit of history (optional)

Simulation

• Terrestrial Coordinate Explorers
  • (Flat Map Explorer [swf] and Globe Explorer [swf])

Celestial Equatorial Coordinates

• Celestial Equator, Declination, Right Ascension

Simulation

• Celestial Equatorial Coordinate Explorers
  • (Flat Sky Map Explorer [swf] and Sky Map Explorer [swf])

Seasons and the Ecliptic

• Orbits and Light
