The Science of Sound
This week we thought we would share some cool science experiments to help you see sound!
Musical instruments create sound by moving the air all round them back and forth, sending out sound waves or vibrations that our ears pick up and our brain processes as notes and music.
Below are some experiments that will help you to "see" sound, they are really easy, and you will find everything you need for them in your house!
How does sound work?
Sound is made up of vibrations, or sound waves, that we can hear. These sound waves are caused by objects vibrating, or moving backwards and forwards really quickly.
All sounds a bit confusing doesn't it? This video from House of Sound should help!
What is Sound?
How do musical instruments make sound?
House of Sound have lots of videos showing us how different musical instruments make sound.
This video is all about woodwind instruments, which are instruments that you blow into to make a sound. Have a go at making your own woodwind instrument!
Make the sprinkles dance!
For this experiment you will need some cling film, scissors, sprinkles or rice, a bowl and a plate.
You could also use a speaker instead of humming and play some music through it right next to the bowl.
Cymatics shows us what sound vibrations look like. High and low sounds make the sprinkles or rice move in different ways and even make patterns appear.
Have a look at this video and see for yourself how cool it is!
You might be interested to have a look behind the scenes to see how the experiments were put together.
Remember they were performed under very strict conditions and need to be conducted in a laboratory.
Do not try any of them at home!
Even Disney include the science of sound in their movies.

and note the lightning cage!!!
