Mystery boxes pre lab questions

Make 5 observations for a) A quarter in a box you cant see, and for b). a credit card in a box you cant see as if you were to shake the box and listen to it and describe how you would figure out what they are without describing . That is the pre lab assignment.Describe how you figure out what they are as if you didnt know what they were inside of a closed box. This is the reason the lab report bext week will be called mystery boxes.
Answer them as best you can and just make sure not to miss these points as they are as simple as they sound?
