Potatoes do not store electricity; they have chemical properties which have the latent to transfer energy between characteristic substances to work as an electrochemical booth The common attitude of potatoes is is they store chemical energy or latent chemical energy as people as they consume them. Potatoes (electrochemical compartments alternatively batteries) likewise have stored chemical energy which can be converted to electrical energy to escape a timer or corner on a small light lamp.,http://www.jordan4firerednew.com/
To use the latent chemical stamina in potatoes to create electricity,Jordan 6/7 Gold Pack 2012 , to types of metal are needed. These metals are zinc and bronze These two metals are inserted into a potato to create a chemical reaction to generate an electrical fashionable alternatively flow of electricity (kinetic stamina Wires are connected from the zinc and bronze metals to a timer or light lamp to complete an electrical circuit to grant the stream of electricity.
Science of Potato Batteries
The potato itself has a blend of starches,Jordan 4 Varsity Red 2012, salts,Jordan 4 For Sale, and water. The salt in the potato interacts with the water and releases ions. Ions are atoms is have an electrical dictate Salt releases two electrically charged ions; a sodium ion with a affirmative charge and a chlorine ion with a negate dictate.
Positive electrical charges and negate electrical charges enchant every other. The positive dictate in a metal case in point zinc) longing fascinate negatively charged electrons. The other metal case in point bronze with a negative dictate reacts with the chlorine in the salt in a potato. This attraction of affirmative and negate electrical charges occasions the stream of electrical current alternatively electricity.
Building a Potato Powered Electrical Circuit
Students use problem solving and science process skills as they complete the emulating potato power cell investigation.
Materials (per group)

Procedures
Part 1
Insert a galvanized nails in potato one and potato 2.Insert an uninsulated bronze cable into potato 1 and potato two,Jordan 4 Fire Red 2012,nearly eight cm from galvanized bind.Connect an isolated bronze cord with alligator clips between a galvanized fasten in potato one and bronze cable in potato two.Connect one isolated bronze cord with alligator clips between the copper cord in potato an to the affirmative extremity of the clocks power cell booth.Connect one isolated bronze wire with alligator clips between the galvanized fasten in potato two to the negate terminal of the clocks power cell booth.Students disc their group observations.
Part 2
Screw the light lamp in the light lamp socket.Disconnect the timer from the potatoes.Connect potato 1 to one connection point on the light lamp socket.Connect potato two to an connection point aboard the light bulb socket.Students record their group observations.
Part 3
Students are provided supplemental materials to test hypotheses developed in questions five 6 and 7.
