Welcome to Unit 3 Hearing STEAM: What if we could change size?

On this page we will review some key resources from the Hearing STEAM group which we hope will give you inspiration to plan a relevant lesson with your own learners.

Case study and lesson plan

Idea to Explore

How can we control music and sounds through size?


The sections below – Discover, Define, Develop and Deliver – align to the Design Thinking model:



We talked about questions such as, ‘What is a pitch?’, ‘How do we create different pitches on instruments?’, ‘How does the size of an instrument change the pitch?’ and ‘How do we create different pitches with our voices?’.



In the defining phase, we listened to recorded songs that we received from our partners in the other countries (e.g. the Norwegians singing a well-known children’s song). Subsequently, we started thinking about what kind of instruments we could make to play that same song and send it back to our partners. We looked for inspiration on the internet and came up with different ideas.


In the next phase, the pupils started working on creating instruments. For example, Denmark worked in the woodwork class and made most of their instruments out of wood (e.g. a string guitar).


At the end of the day, the class came up with melodies and beats that could fit the song they had received earlier in the day. They recorded themselves playing their own instruments and uploaded their videos to eTwinning for their partner schools to listen to.

International Collaboration

We exchanged songs and ideas during the day through our project Twinspace on the eTwinning website.

Resources Needed

  • iPads
  • Design programmes and apps
  • Recording gear
  • Materials for making instruments

STEM to STEAM Analysis

Science: The pupils are introduced to size and sound e.g. how shorter chords have faster sound waves and hence a higher pitch.

Technology: Designing and making the instruments, recording music, exploring music and sound apps.

Engineering: Making instruments using a range of materials. 

Art: Designing instruments, composing and playing music on self-made instruments.

Mathematics: Scaling and precise measuring as part of the instrument making.

Padlet – Ideas

Below is a Padlet of examples to help you to think about how you could develop this theme in your own teaching context.
