The teaching unit “Tracing the Invisible” explains the workings of a satellite which uses the light reflected by the surface of the earth for image acquisition and also factors in wavelengths outside of the range of the visible light. In addition to an understanding of the physical contents, the pupils get to know diverse aspects of remote sensing. A virtual professor accompanies the pupils while they are exploring the electromagnetic spectrum.
The online version of the module is currently only available in German.
