The project "Völlig vermessen!" is about engineering geodesy and its fields of application. After an introduction to surveying technology throughout history, the theoretical knowledge is put directly into practice by using a 12-knot string. Then, weather permitting, the girls go outside to the playground where they first measure angles in the terrain with homemade theodolites. Finally, the girls are allowed to measure their schoolyard up close with modern total stations and use this to create a map of the terrain.

In the project “Die Billardhypothese”, the girls learn everything about the so-called ellipse formula. After an introduction to the mathematics of circles and ellipses, the girls first construct and draw their own ellipses using various methods. This is followed in the late morning by the independent derivation of the ellipse formula and the computational and experimental proofs of this. Finally, in the afternoon, the girls build their own elliptical mini-billiard table.

The project "Was Nanopartikel alles können" is about the use of magnetic nanoparticles for selective separation technology. During the course, various experiments and tests will be carried out. The experiments include first synthesizing magnetic nanoparticles and then purifying nanoparticles from a solution. Students will also learn how to separate fluorescent proteins, microalgae, and BSA proteins from a solution. The highlight is crafting your own snow globe, the contents of which can only be seen by using a magnet to separate the nanoparticles.
