Potato battery gathering and recording of data

Some experiments use water, while others need the help of aluminum foil. With some household items, fun science experiments with potatoes increase a child's understanding of how these processes work and allow them to create research projects for school. Potato Clock In this experiment, you power a clock using potatoes as electrochemical cells that convert chemical energy into electrical energy.

Either 12 or 14 gauge 4. Piece of sandpaper or steel wool Procedure: Scuff the nail and copper wire with the sandpaper or steel wool until its shiny b. Push the nail and piece of wire into the flat side of the potato about and inch keeping them an inch or more apart.

Make sure they don't touch. Set the voltmeter on its lowest whole number DC voltage. Its 2 on my meter.

How to Make a Potato Battery

Plug the black lead into the -negative slot also called common e. The nail will be the negative or cathode of the potato battery and the copper wire will be the plus or anode of the battery f.

Turn on the voltmeter and touch the red positive lead to the copper wire and the black negative lead to the nail My potato battery produced 0.

Potato battery gathering and recording of data

The current from this battery will be too small to light a bulb or power an appliance. Will increasing the size of the electrodes increase the voltage? Will larger electrodes increase the amount of current the potato can produce? Will connecting more than one battery in series produce more voltage?

What about more current? What type material will work best for electrodes? Do the electrodes have to be different types of metals in each battery? Will the same metal such as copper work for all the electrodes?

These are all ideas you can use to do a potato battery science fair project. Form your hypothesis, set up the experiment and record your data.

Do some quick research on how to test voltage and test the current flow from a battery. And also on materials used for electrodes and the reasons for choosing them.Cut the potato in half, then cut a small slit into each half, large enough to slide a penny inside.

Wrap some copper wire around each penny a few times. Use a different piece of wire for each penny. Stick the pennies in the slits you cut into the potato halves.

With that said, let’s make a potato battery Objective. We only need a potato, a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. Re: Analysing data: potato battery with 3 types of potatoes Post by Craig_Bridge» Thu Nov 19, pm The water content (hydration) will significantly affect ion mobility which will affect the internal resistence of the "battery".

Test if the potato battery can light up the LED, as shown in Figure 7. Disconnect the alligator clips from the multimeter probes (leave them connected to the copper and zinc electrodes). Connect the red alligator clip to the longer lead of the LED.

Connect the black alligator clip to the shorter lead of the LED.
