Electrolysis is the breaking apart of water using electricity.
When water is broken apart by an electric current, the hydrogen will be attracted to the pencil attached to the negative side of the battery and oxygen will be attracted to the pencil attached to the positive side of the battery.
*After the bubbles begin to form, make a new sketch showing where the bubbles are located.
*Label where the oxygen bubbles and the hydrogen bubbles are found.

(What did they start off looking and what did they end up looking?)
