Feel the vibrations of sound and amplify sound with plastic or metal bowls
As you speak into this old fashioned telephone, it records your voice and plays it back like an echo. See how difficult this makes it to carry on speaking. The time delay can be altered.
Hear how much better sound travels through a solid than through air.
Find out the frequency of the highest pitch you can hear.
Models of internal and external ear parts can be assembled and disassembled into 3 parts.
Try out pairs of musical instruments. One of each pair has been damped to stop the sound from being prolonged and to demonstrate the importance of resonance.
Speak or make sounds into a microphone and see the pattern of the sound displayed on an oscilloscope.
Listen to a radio through a number of different length tubes. The difference of volume and timing in each ear affects where the sound seems to be coming from.
See how the pitch of the notes can be varied by making the string of the tea chest bass tighter or looser.
Use your sense of hearing to work out which tube is connected to which. Try out different removable sections to hear how sound travels differently through them.
Make the string form different patterns of standing waves by adjusting the frequency of sound coming from a speaker that is attached to the string.
Strike the end of a large spring inside a tube to see a pressure wave (like a sound wave).
Feel a wave pulse in a smaller spring.
