Let there be LightMr. Albu and Mr. Cobb

Key Question

Using only the materials provided, how can you make a complete electrical circuit that will light a bulb?”

SB

Explanation

“How were you able to make the light bulb light up?”

“Do you know why the light bulb lit up in that particular arrangement?”

“Why does the light bulb need to touch the battery and the wires at the same time in order to light up?”

“Where on the battery did the light bulb have to touch in order to light up?”

Materials

So we were able to see from testing our circuits that the wire was good at allowing the energy to easily flow through the system. Can anyone tell me what a good word to describe the wire would be?

However there are some materials that inhibit the flow of energy and are not good conductors. What are some examples?

Now if a conductor is something that allows energy to flow easily, what is the opposite of that?
