How does the cowbell make sound

• The swinging of the bell causes the clapper to vibrate.

• The metal of the bell absorbs the sunlight, which causes it to vibrate.

• The swinging of the bell causes the clapper to hit the bell and vibrate the metal.

What is an insulator?

• a closed loop that electricity flows through

• an object that has the properties of a metal

• a material that allows electricity to easily flow through it
