Vocabulary
This is an electric charge in motion.
What is an electric current?
To understand electric charges, we start by looking at these: the tiny building blocks of everything.
What are atoms?
True or False: Most electricity is on the go.
What is True?
True or False: Other materials do not allow an electric current to move easily through them.
What is True?
This is the first part of a circuit and provides the energy to move electric charges.
What is an energy source?
A material through which an electric charge can move easily.
What is a conductor?
Most atoms have these 3 different types of particles.
What are protons, neutrons, and electrons (or positive charge, negative charge, and no charge/neutral charge)?
Fill in the blank: An electric current flows quickly and ____________ from one place to another.
What is invisibly?
Name two insulators the books mentions.
What are plastic, rubber, glass, dry wood, erasers, or chalk? (Must name two)
This is the second part of a circuit, and through these, the electric charges flow.
What are wires?
A material through which an electric charge moves with difficulty.
What is an insulator?
Charged particles can move between these.
What are objects that are close to each other?
True or False: The flow of electric charge is the same in all materials.
These type of insulators are used on power lines to stop the current from flowing out of the wires.
What are glass insulators?
This is the third part of a circuit, and they transform energy to other forms of energy.
What are resistors?
An electric charge can flow in only one circular path.
What is a series circuit?
This happens with positive and negative charges no longer balance.
What is static electricity?
Name two good conductors that the book mentions in Lesson 1.
What are copper, gold, silver, metal scissors, graphite in your pencil? (Must name two)
Electricians wear these to help protect them from electric shock.
What are special shoes with thick, rubber soles?
This is the fourth part of the circuit, and it open and closes the circuit.
What is a switch?
This has two or more paths through which electric charges flow.
What is a parallel circuit?
Moving charges generate this energy, which can change into sound energy, light energy, or heat.
What is electrical energy?
Most of these are good conductors.
What are metals?
Plastic over the metal wires in a circuit does this.
What is that the plastic insulator makes the cord safe to handle?
This is the difference between a series circuit and parallel circuit.
What is if the loop breaks in series circuit, the current stops but in a parallel circuit the current will still flow?
