Science Buddies: "Ask an Expert"

Hi im in 7th grade and im doing my science project about Cymatics and im trying to do my Problem statement but i cant think of what i would put as a problem statement for Cymatcis. If anyone has any suggestions plz help me and it will be greatly appreciated.

Your problem statement must answer three questions:
What is the problem or need?
Who has the problem or need?
Why is it important to solve?

One can think of Cymatics as sound visualization.

Think a little bit more about the variables in your experiment and that will help you with the problem statement. What are the dependent and independent variables?

What would you expect to learn about the process when you change a given variable (Say sound amplitude or sound frequency)?

good luck and let us know if you still need more help...
