A (electric circuit, water meter, electric meter) is used to measure how much electricity was used.
What is an electric meter.
400
In this type of circuit (series, parallel), if one light bulb goes out, they all go out.
What is a series circuit.
400
Electric bills record how many __________ we use each month. (Think about the home energy use project)
What is kilowatt-hours.
500
An electromagent is a wire with electricity flowing through it, wrapped around (an insulator, a conductor).
What is a conductor.
500
Like poles on a magnet will (repel, attract) each other.
What is repel.
500
Batteries produce this type of current (direct current, alternating current). (This was in the Disney video).
What is direct current.
500
With Mrs. Timm's example of a parallel circuit, when one light bulb was unscrewed, this happened to the other light bulbs.
What is they stayed on and got brighter.
500
Clothes dryers use a lot of electricity because they produce this.
What is heat.
