Stations-ID: A006

Instructions:

A round track – But is the chair driving on it in its initial position after one round?

• How many rails is the track made up of?
• In what position would you arrive after one round, if the chair could not turn?

The stainless steel construction has a different angle in every segment, which could not be calculated before the build. Therefore, a wooden model had to be built to scale to discern the correct measurements required.

Stations-ID: A009

Instructions:

How can ice skaters do such fast pirouettes? On the pirouette machine, you can try to speed up or slow down the rotation. The rotating chair in the hall works similarly! 

• Stand on the platform and hold onto the handrail. Try to get yourself spinning with your feet. What happens if you pull yourself towards the centre?
• What happens when somebody slowly climbs onto the moving platform?
• What happens when somebody jumps off?

On the pirouette machine, several visitors can experience the principle of conservation of angular momentum. You can find a theoretical explanation of this principle at the ‘rotating chair’ 

This station was conceptualized and built by students of the Ernst-Haeckel-Gymnasium.
