5.3 Cup Xylophone
Can You Make A Xylophone Using Glasses & Water?
Follow along with this fun challenge just completed by our 4th & 5th Grade Students in their Science of Sound Unit. Using a set of 7 glasses (all the same size!) and different levels of water (of course, you can color the water if you wish), create a scale of pitches by putting just the right amoung of water in each glass.
Take a video of yourself playing your scale or simple song and email it to makerspace@hawken.edu
How To
Math Extensions
How much water do you need in each glass to create different pitches? If you have access to an instrument in tune (such as a keyboard or recently tuned instrument), compare your pitch to the pitch on your instrument. You can also use tuner apps. How much water creates each of the notes in the C major scale?
What is the ratio of water in each glass. Does it double each time you change pitches? What is the relationship between the water volume in each of the 7 glasses?
Compare different glass materials. Using a tuner app to compare, how does a denser glass with the same amount of water effect the pitch of the glass?
