Discovering levers

When a family arrives at the exhibition in the Children's Wing, it is difficult to know where to start. The exhibition is intended for children aged, but calls on the whole family to pull up their sleeves and get to work.

The exhibition invites us to operate simple machinery and to check its efficiency.

Simple machinery, like the crane, the screw and the pulley demonstrate a simple principle: The "mechanical advantage". This means that one can gain distance at the expense of force or force at the expense of distance.

The giant spoon in the "balls and forces" exhibit, the door handle and the crane for lifting weights - all use this principle, as do the pulley-blocks on the deck of a ship and in the exhibit "Pulley Elevator".

Discovering lever

The exhibition has a number of focal points: a small "infinite room" that is a sort of kaleidoscope through into which one can enter, and a wall of lenses through which one can look at what is happening in the exhibition area without being seen.

In the center of the space is the "balls and forces" exhibit - the centerpiece of the exhibition. Here, with the help of various machines, the children raise balls at a number of operating stations.

Levers - Mirrors

The various discovery environments are accompanied by written explanations: discovery sentences that the children said or can say when operating the exhibit. For example:

  • "The crane in the exhibit is like a giant spoon. A spoon is also a crane." (balls and forces).
  • "You can turn the propeller without touching it" (one cogwheel turns another).
  • Each corner has a different angle and the number of reflections in it is different" (small infinite room).
