After discussing the Electric Fruit Investigation of the 1996-1997 class, we decided to test a large and small sample of four different fruits and vegetables for a three week period.

Circumference: The 1996-1997 class found that items with larger circumference produced more electricity, but this year we found that the smaller items (especially the potato and the apple) produced more electricity than larger items of the same variety.
Mass: Unlike the 1996-1997 class, we found that the heavier items usually produced less volts than the lighter ones.
Type: The potatos usually produced the most electricity and the jicamas usually produced the least.
Comments: Our large potato started to grow. Our large jicama was almost completely moldy by the end of our observation.
