What is electricity?
a form ofenergy that is used to power devices
100
What is an insulator?
An insulator is an object that does not allow electricity to travel through it.
100
To avoid an electric shock, you should never use electric appliances near...
What is water.
100
How is hydro electric power produced?
The gravitational energy power of water is used to turn the wheels of a turbine that is connected to a generator that transforms the kinetic energy of from the turbine in electrical energy.
100
What is an electron?
An electron is a negatively charged part of an atom.
200
What is a conductor?
A conductor is an object that allows electricity to pass through it.
200
How to avoid electricity dangers.
What is not overloading outlets, unplug unused appliances, don't use appliances near water
200
How is nuclear energy produced?
Uranium atoms are split in a reactor and this creates a tremendous amount of heat that is used to boil water in large tanks. The steam created from the boiling water rises and turns turbines to generate electricity.
200
When objects have different charges, do they attract or repel each other?
Objects with opposite charges attract one another and objects with the same charge repel each other.
300
Name three objects that we tested conduct electricity.
What is penny, spoon, paperclip.
300
Why is it important that wires in your wall are covered in plastic?
The plastic is an insulator that prevents you from making direct contact with the electricity in the wire.What is
300
An electrical circuit that has only one path with multiple electrical devices connected in a single row.
What is a series circuit.
300
How are fossil fuels like natural gas, oil and coal used to generate electricity?
The fossils fuels are burned to heat water which boils and creates steam. The steam rises and turns turbines which generate electricity.
300
The part of an electrical circuit that opens or closes the circuit.
What is a switch
400
If I take a battery and connect it to a light bulb using wires, then I would have an example of this
What is an electric circuit.
400
Name three things that we tested that were insulators.
What is wood, rubber, chalk.
400
An electrical circuit with more than one electrical path with each electrical device connected directly to the power source
What is a parallel circuit.
400
Two problems with burning fossil fuels to generate electricity.
What is air pollution, acid rain, carbon dioxide from the burning process contributes to the greenhouse effect
400
Connecting too many appliances to one circuit is dangerous.
What is overheating and causing a fire?
500
Why does a light go one when you flip a light switch to the on position?
When the switch is in the on position, there is no gap in the circuit so that the electricity can travel in a complete circuit. When the switch is in the off position, there is a gap in the circuit that prevents the electricity from travelling in a complete circuit.
500
The phenomenon associated with lightning strikes or when you "shock" a friend.
What is an electrostatic discharge.
500
the third prong called in this picture
What is a Ground wire?
500
The 2 types of electricity.
What is static and current.
500
Name three ways to generate renewable electrical energy.
What is solar power, wind power, water power
