We can perceive sounds of different levels and volumes, although there are individual differences between people. Humans cannot hear all the sounds that are produced on this earth.

Information and Ideas:
• The teacher/educator should mount the pole at a height that the children can easily reach. The pole could be between two tables or chairs, for example, with just the ends of the bar resting on the chairs or tables. It should be possible to suspend several ob-jects from the pole so that they can swing freely. For this purpose, the teacher/educator has to attach pieces of string of the appropriate length to each of the objects and make a loop at the end to hang them on the pole.
• Please observe the general safety and hygiene measures and safety instructions in the respective teaching methods as well as the applicable safety guidelines for your school.
• All materials mentioned in the instructions will have to be purchased directly from commercial sources.
