When making a circuit would the list of items be good or bad choices to connect the dry sell to the load? Why?
String, wood, rubber
No, because these items are insulators and will not allow the energy to flow through.

Look at the system below. Will the light light up? Explain:
No, the light will not light up because the wire is not connected to the conductors.

Sammy was trying to turn the light bulb on but when he made his circuit it did not light what does he need to do to get the light to work?
He needs to turn the switch on to finish the circuit.

True or false
An open circuit does not have a break in the path.
False, an open circuit has a break in the bath that causes it to now allow energy to flow through.

If you rub a balloon on your hair and hold it over small pieces of paper will it pick it up? why?
Yes, because of static electricity.

Ms. Thompson made an electromagnet and it had paper clips stuck to it. The wire slipped off the battery and the paper clips fell to the floor. Why did they fall?
The electrical energy stoped flowing through the electromagnet.
