What does this mean?
How to reference this medium
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 phenomena
Sound/acoustics: parameters
Vibrations and waves
