Atomic Theory
100
These are collected when a balloon rubs on wool.
What are electrons?
100
Type of particle that orbits the nucleus of atoms.
What is/are electrons?
100
This is the movement of electrons.
What is electricity?!?!?!
100
This component opens and closes circuits.
What is a switch?
100
This particle has positive charge.
What is the charge of a Proton?
200
This substance allows electrons to flow freely.
What is a conductor?
200
Particles found in the nucleus of atoms.
What are protons and neutrons?
200
Energy from the D-cell BEGINS from the terminal with this charge.
What is the negative terminal?
200
This is made up of many cells lined up together.
What is a battery?
200
This particle has negative charge.
What is the charge of an electron?
300
This is why lightning strikes tall things like trees.
What is the negative charges are attracted to the positive charges of the earth and the tall object (tree) is the closest and easiest way down?
300
Elements are made up of only one kind of these.
What is/are atoms?
300
This is the movement of enormous amounts of electrons in nature.
What is lightning?
300
This component changes electricity into motion.
What is a motor?
300
When they get close, these charges repel each other.
What is/are 2 alike charges?
400
This is why our wires in lab are coated with red plastic.
What is...the plastic is an insulator and keeps the electricity flowing in the wire and not through us?
400
Two hydrogen atoms and one oxygen atom.
What is water?
400
These components are energy users.
What is/are resistors?
400
Another way to say that you have a complete loop of electricity.
What is a closed circuit?
400
These charges want to be together.
What is/are positive and negative charges?
500
This schematic diagram shows a D-cell, switch and unlit bulb.
What is (draw on whiteboard)? Switch MUST be drawn open and the circuit connected.
500
These looks like "Mickey Mouse" heads and conduct electricity.
What are water molecules? (must say both words for full points...water just gets 250)
500
These "break" the flowing loops of electricity in your house if there is a problem (thereby preventing fires).
What is/are circuit breakers?
500
This type of electrical drawing uses symbols for components.
What is a schematic diagram?
500
This particle has neutral charge.
What is a neutron?
