EAAE Summer School Working Group (Finland)

Abstract

In this workshop, we first find our location on the globe by the Sun and Polaris, the Pole Star. After that, we determine the coordinates of another location in relation to our position using a gnomon and timing with the help of a mobile phone. We use a big gym ball to demonstrate the idea, marking the positions and meridians on it. Students handle the conceptions of latitude, longitude, time difference, declination and altitude of the Sun.
