How Do You Make Electricity From Saltwater & Oxygen For A Science Project?
The molecular breakdown of metal is called “oxidation,” and occurs most commonly with iron left out in the elements. When iron is exposed to oxygen for long periods, it becomes iron oxide, or rust. This simple battery uses saltwater and oxygen to oxidize iron rapidly to create electrical energy. Screw the light bulb base into the block of wood using the electrical drill and wood screws. Be sure not to tighten the screws too much or you may crack the light bulb base. Screw the light bulb into its base. Rest the coffee mug on the wood block. Use duct tape to fasten the iron and magnesium electrodes inside the coffee mug. Ensure that the strips run down opposite sides of the mug and that a small section of the strips is exposed near the top. Use alligator clips to attach one wire to the positive terminal of the light bulb base and the exposed section of iron electrode. Use alligator clips to attach the second wire to the negative terminal of the light bulb base and the exposed section of
