The seasons

Principle

In conducting the experiment the students will not have any technical problems. But great demands will be placed on their abilities to concentrate and to observe exactly. The methodological instructions are fairly extensive, but this is justified by the fact that the students can make the important observations on their own - also with the aid of the sketch in Fig. 11.
