You will be using a string (yarn, shing line or dental oss) that is approximately 3feet long. Tie a spoon or pen! pencil to the middle of that string. The two open ends of the string will be wrapped around your index fingers and then plug ears with the same fingers. Gentle knock the spoon against a table or with another object. What happens? Try it again with a different object, (plastic spoon, ink pen, wooden spoon, smaller/larger metal spoon). What happens with harder taps or softer knocks? Include a picture of your set up. - What happens with harder tap or softer knock? - What is the conductor? What is resonating? - What is the result of resonance? - How can you tell a change in decibel level? - Why is there a difference between wood, metal or plastic? Did you try different string type materials, did it make a difference
