A student was looking for a magnet in a box. She used two compasses to detect the magnet. How did she know when the compasses detected the magnet?
What is the two compasses pointed in the direction of the magnet, like arrows
200
Which of these is the best definition of an insulator? a. an insulator is the component that turns the circuit on and off. b. an insulator is a material that sticks to a magnet. c. an insulator is a material that does not allow electricity to flow through it. d. an insulator is a material that keeps the circuit warm
What is c. an insulator is a material that does not allow electricity to flow through it
200
Which real drawing shows a parallel circuit? A,B, C or D
What is C
200
One way to make an electromagnet stronger is to do what?
What is wind the wire more times around the core
300
allows electricity to flow (all metals are these)
What is conductor

300
Which real drawing shows a complete circuit that will allow the lightbulb to light? A, B, C, or D
What is B
300
Which is the type of circuit to use for Christmas lights, and why?
What is a parallel circuit, because when you take one light bulb out, the rest stay lit AND because it travels through multiple pathways
400
This question has two answers: 1. One pathway only to allow electricity; if one lightbulb on Christmas lights goes out, all lights go out 2. Multiple pathways allowing electricity to flow; if one lightbulb on Christmas lights goes out, the rest stay on
What is 1. series circuit 2. parallel circuit
400
Which of these items conducts electricity? a. aluminum foil b. fabric c. basketball d. eraser
What is a. alumninum foil
400
In a circuit that tests for insulators and conductors, a lightbulb is used to....
What is b. show that electricity is running through the circuit
400
Which schematic design will allow a motor to run? A, B, C, or D
What is D
400
What is wrong with this picture? Why won't the lightbulb light?
What is because two of the wires are coming out of the negative end of the battery, and one should be on the positive to create a complete circuit
500
A coil of wire, wound around a piece of iron or steel, which produces a magnetic field when electricity flows through the wire.
What is an electromagnet
500
A magnet attracted a paper clip even when a think piece of cardboard was placed between the magnet and the paper clip. But when a sponge was placed between the magnet and the paper clip, the paper clip fell to the floor. Why did this happeN?
What is because magnetism goes through cardboard, thin materials, but not through a sponge, thick materials
