CLOSED CIRCUITS
This type of circuit allows electricity to flow.
What is a closed circuit?
A lamp changes electrical energy into mostly this type of energy.
What is light energy?
Materials that allow electricity to flow easily are called these.
What are conductors?
Rubbing a balloon on your hair creates this type of electricity.
What is static electricity?
This is the process of collecting information using your senses.
What is observation?
Turning on a light switch usually does this to a circuit.
What is closing the circuit?
A toaster changes electrical energy into these two forms of energy.
What are heat energy and light energy?
Materials that do not allow electricity to flow easily are called these.
What are insulators?
Two balloons rubbed on hair push away from each other because they have these types of charges.
What are the same charges?
Scientists use these to record results from an investigation.
What are data?
A complete circuit must form this shape.
What is a loop?
A fan changes electrical energy into this form of energy.
What is motion (mechanical) energy?
Copper wire is a good example of this type of material.
What is a conductor?
A positively charged object will do this to another positively charged object.
What is repel it?
Which is more scientific: gathering opinions or recording observations?
What are recording observations
A battery, wires, bulb, and switch are connected, but the switch is open. The bulb will do this.
What is stay off (not light)?
A radio changes electrical energy mostly into this type of energy.
What is sound energy?
Rubber covering around a wire is this type of material.
What is an insulator?
A charged balloon can do this to a neutral wall.
What is attract it?
A student changes one variable and measures the result. This type of investigation is called this.
What is an experiment?
Daily Double!
Two students build circuits. One bulb lights and the other does not. Give one reason the second bulb might not light.
What is an open switch, dead battery, loose connection, missing wire, or open circuit?
Daily Double!
A blender uses electricity to spin sharp blades. Describe the energy transformation.
What is electrical energy transformed into mechanical (motion) energy?
A paper clip, penny, and metal spoon all belong in this group.
What are conductors
A negatively charged object will attract this type of charge.
What is a positive charge?
If another scientist follows the same directions and gets similar results, the investigation is considered this.
What is replicable (repeatable)?
