Problem: My dad said somebody at the cafeteria ordered too many potatoes
so everybody has to do a science project on potatoes now
for Take Your Daughter to Work Day and lunch will be french fries.

Mr. Johnson said we could use as many potatoes
as we liked for our projects but I'm only going to use one.
I asked my dad if I could do a different project
because I already did a potato battery project in class last year and he said no,
Mr. Johnson would get mad.

Hypothesis: Probably the potato will do the same thing it did last year for my class project,
except maybe not because I had a new potato last time and this one is pretty old.
my dad says his hypothesis is whoever ordered all the potatoes will probably get fired.

Conclusions: Last time my potato battery produced 1.5 volts.
This time it got 1.6, so I guess it doesn't matter how old the potato is.
The current from the potato battery did not produce enough volts to power anything important.
If I used more potatoes maybe I could have gotten more volts,
but the one dad brought home smelled and I didn't want more.

Materials: One potato, a nail, a volt meter, a piece of copper wire, a piece of steel wool

Procedures: I did the same thing I did last time.
