XP 3: How can I identify and communicate the pitch of sounds?

Think About

How do we identify the pitch of a sound?

How do we communicate the pitch of a sound?

Get Started

1. If you are unfamiliar with the term “pitch,” watch this short video that gives a simple explanation:

1. Find some objects of different sizes that make sound.
2. Strike or tap them with something.
3. Can you use your ear to organize them from lowest to highest pitch?


Why do we need to organize pitches from low to high? 

1. Take a look at what people are able to do when they can organize pitches with something as simple as water and glass bottles or glasses!

Now, go somewhere where you can use water and not damage anything.

1. Watch one (or more of the following videos) that demonstrate how to create an instrument with glass bottles and water. 
2. Try the project of creating a water instrument and experiment with identifying and communicating the pitch of sounds by organizing your instrument going from low to high pitches.
3. Make sure you have the permission of an adult and that you are extremely careful to not damage the glass bottles or glasses you use. Do not tap the glass with anything metal.

If you prefer written directions with a video on how to create a water instrument, check out this sciencesquad webpage.

If you prefer blowing across glass bottles (instead of tapping them) try this project.

1. All you need to do for this XP is to have 3 – 4 pitches organized from lowest pitch to highest pitch
2. Adjust the water levels to get the pitches you want
