Feel the Noise - Sound and Material Investigation

We had great fun exploring the types of material through which sounds can travel! We conducted experiments and observed how well sounds can travel through various materials such as water, sand, bubble wrap, polystyrene chips and fabric. We then tabulated our results and wrote up our conclusions.
