Experiment set GEOMETRY 2

From inside out
This set of experiments provides a completely new introduction to spatial geometry. By using high-quality coloured acrylic shapes and modern cylindrical magnets, there are unexpected possibilities to illustrate the mutual position of lines and planes.
But the approach to developing the properties of the most important geometric bodies is also new: The bodies are not viewed from outside inwards, but built from inside outwards. This method makes it easier to develop and promote spatial imagination. Further examples include:
- Symmetry planes are discovered using a real mirror surface
- Spatial and surface diagonals as well as inclination angles are compared with suitable triangles
- Structures are held stable by using special magnets
- With ten square plates, the students work out the principle of Cavalieri and then apply it to various pyramid shapes
