A fun way to review REDOX in high school is to have students play a bingo game. They can work individually, pairs, or even teams. This is a great way to review for a test. The teacher is provided with a list of 25 terms and the appropriate concept/description. 28 different Bingo cards are included with the terms randomly located. The topics and terms include, but are not limited to various oxidation numbers, anode, cathode, reduction, oxidation, voltaic, and electrolytic.

New York State Objectives:
Commencement Level Physical Setting, Chemistry
• An oxidation-reduction (redox) reaction involves the transfer of electrons (e-). (3.2d)
• Reduction is the gain of electrons. (3.2e)
• A half-reaction can be written to represent reduction. (3.2f)
• Oxidation is the loss of electrons. (3.2g)
• A half-reaction can be written to represent oxidation. (3.2h)
• In a redox reaction the number of electrons lost is equal to the number of electrons gained. (3.3b)
• Oxidation numbers (states) can be assigned to atoms and ions. Changes in oxidation numbers indicate that oxidation and reduction have occurred. (3.2i)
• An electrochemical cell can be either voltaic or electrolytic. In an electrochemical cell, oxidation occurs at the anode and reduction at the cathode. (3.2j) patina (copper-Statue of Liberty)
• A voltaic cell spontaneously converts chemical energy to electrical energy. (3.2k)
• An electrolytic cell requires electrical energy to produce chemical change. This process is known as electrolysis. (3.2l)
• Use an activity series (Table J) to determine whether a redox reaction is spontaneous
