By the end of the 2nd grade, students should know that:

  • The sun can be seen only in the daytime, but the Moon can be seen sometimes at night and sometimes during the day. The sun, Moon and stars all appear to move slowly across the sky. 4A/P2

National Science Education Standards

Science and Technology -- Content Standard D

Grades K-4

  • The sun, Moon, stars, clouds, birds, and airplanes all have properties, locations, and movements that can be observed and described.
  • The sun provides the light and heat necessary to maintain the temperature of the Earth.


  • Objects in the sky have patterns of movement. The sun, for example, appears to move across the sky in the same way every day, but its path changes slowly over the seasons. The Moon moves across the sky on a daily basis much like the sun.
