C3 Sense of hearing (teacher instructions)

Experimentation instructions for Experimento - 8+:Background information on the content and practical information on conducting the "Sense of hearing” experiment, which comprises three subexperiments.The teacher instructions include information on the following: the main question, relevance to the curriculum, skills, notes on conducting the subexperiments, the research group, further research assignments, and the reference to values.The experiment comprises three subexperiments:• Parade of ears• Directional hearing• Making loud noises quietOur sense of hearing is very important. However, we can lose it permanently, for example, through exposure to too much noise. Many children are unaware of this, and therefore it is important to sensitize them to their own, individual sense of hearing and to provide them with a better understanding of hearing.Notes: • Observe the safety information in the instructions 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.

Sound propagation

Experimentation instructions:Experiment cards for students on sound propagation, for example, make a string telephone or propagation of sound waves in a glass of water.Sound needs a medium for propagation. Information and ideas:• Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.• The experiments on sound propagation show the students that sound needs a medium to propagate. It becomes clear which materials conduct sound better and which materials slow the propagation down.• The experiments can be done either in groups or as station training.Relevant for teaching:Acoustic phenomenaSound/acoustics: parametersVibrations and waves

Water as wave model

Video (00:07 minutes, without sound):A stone is thrown into calm water, ripples are formed.The vibrations emitted by a source of sound can be compared with the ripples or waves created when a stone is thrown into calm water.It is, however, directly comparable only as far as the concentric shape of propagation is concerned. Looked at in detail, the vibrations are in fact very different. Information and ideas:Students can do the experiment themselves on an excursion out of school.
