Vibrations and solid materials
I can explain how sounds can travel through a solid medium to our ears.
Lesson details
Key learning points
- Sound travels from an object through a medium to our ears.
- Vibrations can be heard when travelling through some solids, such as taut string and cups.
- Scientists use results to make simple conclusions and raise further questions.
- Vibrations travel through a solid medium more quickly. We can hear these sounds louder and more clearly.
Common misconception
Children often think that sounds will be quieter and more muffled when travelling through a solid medium.
It is important for children to try string telephones out for themselves to hear how sounds can be louder and clearer travelling through a solid medium.
