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.
Keywords
Vibrations - Vibrations are when an object moves very fast from side to side.
Medium - Vibrations need a medium to travel, such as a solid, liquid or gas.
Solid - A solid is something that holds its shape and is not a liquid or a gas.
Taut - Taut means to be stretched firmly or tightly.
Conclusion - In a conclusion, scientists explain what the results show or mean.
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.
Equipment
String, scissors, cups with holes pre-cut.
