Here a template for students to use their knowledge about sound and create their own musical instruments. It incorporates Science and T&E
They need to
- write what they need
- draw a plan of what they want their instrument to look like
- write how their instrument is going to make sound
There is space for a photo of them and their instrument and a smiley/sad face check to see if their instrument actually makes sound.
I like to enlarge it to A3 to allow lots of room.
