Electricity & Magnetism
Magnetism – material that attracts metals and materials that contain
metals.
Magnetic Pole – the source of the attraction or repulsion of a
magnetic object.
Electricity – an electric current, a form of energy.
Current – a continuous flow of electrical charges through a material.
Conductor – material that allows electrons move easily and freely
forming an electric current.
Insulator – material that does not allow electrical charges or
electricity to flow through it easily.
Chemical Equation – a short, easy way to write a chemical reaction
with symbols.
Chemical Reaction – a chemical reaction involves two kinds of
observable changes: (1) the combining of new substances and the
change of energy.
Precipitate – a solid that forms from a solution during a chemical
reaction.
Endothermic Reaction – a chemical reaction in which energy is
absorbed.
Exothermic Reaction – a chemical reaction in which energy is
released.

Reactant – The substances added together that you start with that
are at the beginning of a chemical equation (left side of the
equation). In other words, a substance that takes part in a chemical
reaction.
Product- The substances produced when the reaction is complete
(right side of the equation). In other words, a substance formed
during a chemical reaction.
Coefficient – a number placed in front of a chemical formula in an
equation, example: 2H2O
