Experiments on bundling of sound
Experiment cards for students on bundling of sound, for example, megaphone or experiment with tube and funnel.
By the way: Sound can be bundled or funnelled. In the hearing process, this function is carried out by pinna and ear canal.
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 the bundling of sound show the students that sound is often funnelled or bundled when it is transmitted or perceived.
• The experiments can be done either in groups or as station training.
