Science Sparks – Making Music (Week 7)

In this weeks Science Sparks we are making music using glasses filled with different levels of water. It is a great way to make a musical instrument, pretend to be in a band and learn a little science along the way! So come and take part in science sparks this week! 

I tell you, I bet the Kings of Leon have done this and if not they should! 

What you will need

Some glasses or bottles
Wooden stick or pencil

What to do

Take your glasses and fill them with different level of water. The first glass should be the fullest and the last glassy have the least amount of water. 

Tap each glass on the side and observe the sound!

See if you can create some music!

The science sparks bit!

When you hit the glass you create vibrations. vibrations make sound. you can prove this by putting your fingers to your throat when you talk – you can feel the vibrations! The size of the vibration is called the amplitude – the bigger the amplitude the louder the sound. The vibrations have to travel through the water – the distance affects the pitch, so the more water the longer the distance, the lower the pitch, the less water, the less the distance the higher the pitch! 

Go and test it out! 

If you like this why not have a go at some of our other experiments on our Science Sparks page. 

Also if you fancy winning a Lego dynamo torch why don’t you take park in our build a bridge challenge!
