Answer 2

WORKING MODEL TO TEST THE PRESENCE OF STARCH USING POTATO.

Material required :

Potato, Wires, Two iron nail, A bulb (or a battery and a switch).

Working model :

• Take a potato and priick the iron nails on the both ends of it, a bit deep. ( To the extremes, if possible ).

• The more the distance between the nails, the more ions (of starch) attract them (terminals), resulting more voltage.

• The salt in the potato acts as a salt bridge between the nails, makes the ions travel through the nails.

• Connect one wire's one end to one nail and other end to the positive electrode of a bulb (or battery).

• Connect second wire's one end to one nail and other end to the negative electrode of a bulb (or battery). If you opted the battery, switch it on, now.

• The bulb starts to glow.

Quick fact :

Researchers say that an 8 minute boiled potato produces 10 times more electric current than the raw one does.
