How to make a musical instrument from water glasses and a pencil! Students get to make it, play it and then describe what they hear and see if they can change what they hear. Along the way they will learn why the sounds change in the water.
Instructions and worksheet with tasks on how to make sound waves travel though water and the effect it has on them.
Tried this on with all ages and can be gauged to their language and abilities.
It is fully editable as I think that the teachers who use my stuff may like some of the ideas, but they know their students best!
All suggestions gratefully received on how to improve!
It is free again for a short time, so let me know if you liked it or how i can make it better!
