The Enviro Battery! Mr. Potato and Lemonstein Attempt to Save the World with their Genius Creation : The Enviro Battery!
How Does Their Enviro Battery Work? Electricity is generated when you place zinc and copper plates connected together into an aqueous medium such as a potato, mud, water, or a piece of fruit. The zinc plate is the negative electrode and the copper plate is the positive electrode. When the metals are immersed into the electrolyte ( aqueous solution), a chemical reaction takes place. Individual electrons are released when the acid in the electrolyte breaks down the atomic structure of the copper and zinc. This flow of the electrons from a reactive metal (zinc)to a less reactive metal (copper) forms a small electrical current, which will light up a small light bulb! “They decided to start with this experiment...”
Things You Need to Know... The positive terminal is always the red colored wire, and the negative is always the black colored wire. Always connect the black (negative) to the zinc plate (or the more reactive metal) and the red (positive) to the copper plate (or the least reactive metal). “Lemonstein and Mr. Potato first need to train their workers before they attempt to save the world”
How Did They Make a Battery with Water? When you add vinegar to a water solution, it will cause the LED to light up brighter. This is because water is a neutral PH and metals are more reactive in acidic solutions. The current produced is stronger when vinegar, or another acidic solution,is added to the water. Or, another experiment...
How Did They Make a Paper Clip Battery? How Did They Make a Paper Clip Battery? Most metal paper clips are plated with a layer of zinc. When the metals are inserted in the acidic water, a reaction takes place and a current is formed! Or, this experiment...
How Did They Make a Coin Battery that Sings? Most brownish colored coins are made from copper or a copper alloy. The coins act as a substitute for the copper plates. So when a connection with more reactive metal (like aluminum) is mixed with an acidic solution like vinegar, a reaction takes place. It will create enough current to generate sound or even light!!!! Or,this experiment...
How Did They Make a Fork Battery? The fork acts like the positive electrode of the battery. Most tableware utensils are plated with a metal which is less reactive than zinc. When both the utensils and zinc plates are inserted into the lemon, a reaction takes place. Electrons move from the zinc plates to the fork forming a current. AHHH, the last experiment!!!
They combined all they knew and learned and gave it to Dr. ACE and his Mentors to teach the students of today so that those students can make tomorrow a better day! And that's how they saved the world, kids!!!!
Fun Facts “Voltaic Pile” : Did you know that one of the first batteries was actually a stack of metal discs separated by cotton that was soaked in salt water? Gaston Plante invented the first lead-acid battery in 1859, and Thomas Edison invented the first alkaline cell in 1914! How are batteries recharged? --Recharging a battery simply requires that you reverse the flow of electrons using a separate energy source such as electricity or solar panels. The problem with recharging is that the battery will start to lose its charge a little faster each time it is recharged. Why are store bought batteries hazardous to the environment? – They are pollutants!!! The chemicals in batteries can corrode and leak into the soil, thus making their way into our water system.
