Experiment set SEEING and HEARING


Fun doing experiments

This experiment set enthuses students right from the start to find out for themselves

  • how they can see,
  • that an image on the retina of the eye is upside-down and smaller than what is being viewed,
  • the purpose of the pupils,
  • why it is necessary to have two eyes,
  • where the colours of the rainbow or autumn leaves come from
  • why it is necessary to have two ears,
  • how can you phone with a cord.

Working in partnership or in class experiments

As a rule, the experiments are carried out in pairs. However, some experiments are designed for the whole class to participate. Apart from the experience of experimenting together with others, this also particularly encourages a sense of responsibility, consideration for others and teamwork among the class members.

Multi-functional apparatus

Apparatus that can be used for multiple purposes not only saves money but also ensures that the cases do not have a confusingly large amount of equipment. In particular, such apparatus also encourages children’s own creativity. For example, the extension rod for the lens holder serves as both the object for creating shadows and as a hammer for striking the sound plates.
