Question: Is a plastic spoon a good or poor conductor?
Answer: Poor conductor

Question: Is a paper clip a good or poor conductor?
Answer: Good conductor

Question: Are rubber boots a good or poor conductor?
Answer: Poor conductor

Question: Is a metal key a good or poor conductor?
Answer: Good conductor

Question: Define conductor.
Answer: A conductor is a material that allows electricity to flow through it.

Question: What part of the circuit is the path?
Answer: The path is the part of a circuit along which electricity travels (wire).

Question: What part of a circuit is the source?
Answer: The source is the part of a circuit that pushes electric current along the path (battery, outlet).

Question: What part of a circuit is the load?
Answer: The load is the part of a circuit that uses electricity by giving off light, heat, or magnetic interaction (the light bulb or radio).

Question: Explain an open circuit and how the switch works.
Answer: An open circuit has a break in the path so that electricity cannot flow, so the switch is open.

Question: Describe a closed circuit and talk about the position of the switch.
Answer: A closed circuit has a complete path which allows electricity to flow, and the switch is closed.

Question: Describe heat energy.
Answer: Heat energy is associated with the difference in temperature between two objects.

Question: What is solar energy?
Answer: Solar energy is associated with the light generated by the sun.

Question: What is energy transfer?
Answer: Energy transfer is the passing or movement of one form of energy to another.

Question: Talk about energy transfer when the sun melts an ice cube.
Answer: Heat energy is transferred to the ice and changes the temperature of the ice to warm it up.

Question: Name three forms of energy.
Answer: Three forms of energy include heat, light, and electricity.

Question: When you use a plastic comb on your hair, why does it produce static electricity?
Answer: The electrical charge from your hair is transferred to the comb.  The comb becomes negatively charged.

Question: Describe current electricity.
Answer: Current electricity is when the electric charges flow through a wire, and comes from batteries or generators.

Question: Describe the flow of electricity through a complete circuit.  Use a battery, wires, and a light bulb in your explanation.
Answer: The electrical current starts from the positive end of a battery (source), then flows through the wire (path), through the filament of a light bulb (load), and back through the battery through the negative end.

Question: When is static electricity evident in nature?
Answer: Static electricity is the cause of lightening.

Question: Why can you get a shock sometimes when you touch a door knob?
Answer: Static electricity causes electrons to transfer from the door knob to your hand.  The electrons jump and cause a shock.
