The students get to observe the movement of stars in the night sky by analyzing images of the Stellarium Gornergrat and think about the underlying cause. Why do the sun, the moon and most stars rise and set during a day? The aim is to make connections between the apparent movement of celestial bodies and the rotation of the earth. The students learn why there is day and night and how to determine the geographical North by looking at the stars.

Requirements

Learning Objectives

The students…
  • interpret the movement of the stars as a result of the earth's rotation.
  • can explain why there is day and night.
  • know that certain stars never set and are just not visible because of daylight (circumpolar stars).
  • understand why the polestar keeps its position through the night.
  • know that the polestar indicates the geographical North.
  • understand the term of relative movement.
  • can arrange and compare velocities.
