This animation demonstrates the changing declination of the sun with a time-lapse animation. It shows how the shadow of a building changes over the course of a year as the declination of the sun changes.

Climate Literacy
About Teaching Climate Literacy

The tilt of Earth’s axis relative to its orbit around the Sun results in predictable changes in the duration of daylight and the amount of sunlight received at any latitude throughout a year. These changes cause the annual cycle of seasons and associated temperature changes.

Benchmarks for Science Literacy
Learn more about the Benchmarks

Because the earth turns daily on an axis that is tilted relative to the plane of the earth's yearly orbit around the sun, sunlight falls more intensely on different parts of the earth during the year. The difference in intensity of sunlight and the resulting warming of the earth's surface produces the seasonal variations in temperature.

Teaching Tips

  • Educator needs to compose and provide background information on topic/concepts.
  • The building shown is at the University of Nebraska - educator could discuss how similar or different their school's latitude is for comparative purposes.

About the Science

  • The University of Nebraska-Lincoln has created this time-lapse seasons demonstrator. Images were obtained at noon - students can record various observations from this series of images and predict how the sun changes over time.
  • Passed initial science review - expert science review pending.

Technical Details/Ease of Use

  • There is some support for educator teaching this concept (help tab on animation).
