SCIENCE INVESTIGATORY PROJECT
Transcript of SCIENCE INVESTIGATORY PROJECT
There are many food crops, including potatoes, which are wasted every day. Most of the crops are discarded or thrown away. Potatoes are often discarded, being the fourth largest food crop with only so many to buy them. One of the researchers’ goals was to lessen the wasted food crops by finding other uses for them. The researchers also found that this investigatory project is an introduction to the potential of potatoes to generate an ample amount of electricity fit for rural areas. According to the research of the Hebrew University of Jerusalem, a slice of potato can generate 20 hours of light, and several slices of potatoes could power a simple medical equipment or even a low-power computer. Lastly, the researchers wanted to create another source of electricity that is equivalent to the amount of power a regular battery can produce without its toxicity such as alkaline or D cells.
MATERIALS AND PROCEDURES
Alligator clips - It is used to transmit the energy and to connect the ingredients to each other.
Cutter - It is used to cut potatoes.
Voltmeter - It is used to measure and/or check whether the current passes through the wires.
Copper Coins - It serves as positive electrode.
Galvanized nails - It serves as negative electrode.
Led Light - It is used to prove our experiment.
Potatoes - The main ingredient. It is used to conduct electricity.
Step 1: Prepare all the materials needed.
Step 2: Slit the potatoes just enough for the coin and nail.
Step 3: Insert a copper coin into the slitten potato then, insert the galvanized screw on the side part of the potato.
Step 4: Use the alligator wire to connect the copper wire and galvanized screw.
Step 5: Put it in series.
Step 6: Connect the last black and red alligator wires to the Led light.
