List 4 materials that would light up this light bulb when dropped onto the crocodile clips. In 1-2 sentences, describe why it caused the light to turn on using these 4 key terms: conductor, circuit, electrons, flow.

The four items are;

1) Nail, 2) Screw, 3) Key, 4) Scissors

Explanation:

The given electric circuit consist of two batteries that provides electromotive force to help transfer electrons and result in the flow of an electric current when the circuit is completed by providing a conducting path through the crocodile clips. By dropping either of the nail, screw, key or scissors, onto the crocodile clip, the circuit is completed and current is allowed to flow through the circuit, passing through the light, causing it to turn on.
