Electricity activities Tools A B energy the ability to cause a change in something or to move it atoms tiny particles that make up all matter electricity invisible energy that is made up of charged parts of atoms electric charge an imbalance of atomic particles attract to pull together repel to push away static electricity a buildup of electrical charges that are released all at once current electrical charges that flow through a conductor conductors materials that allow electricity to flow through them insulators materials that DO NOT allow electricity to floe through them circuit pathway through which electricity moves Ben Franklin discovered that lightning was electricity Thomas Edison inventor that perfected the light bulb electrical source provides energy to light a bulb or play music electricity receiver a component that uses electricity to make something happen filament part of the bulb that gets hot and produces light switch a device used to open and close circuits open circuit an incomplete circuit that <B>will not</B> allow electricity to flow closed circuit a complete circuit that WILL allow electricity to flow schematic diagram a way to represent a circuit on a piece of paper component one part of a circuit system, for example a bulb or switch series circuit a circuit with only one pathway for the current to flow parallel circuit a circuit that splits into two or more pathways for the current to flow
