To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or limes) that is strong enough to power a small light bulb.

The link below isn't 'complete', but it is a very good beginning.
The hypothesis could be: "I hypothesize that the power of a lemon, when used in a battery or as a cleaning agent, can be attributed to its high citric acid content and acidic properties. I predict that lemons will demonstrate effectiveness in conducting electricity or breaking down stains due to these characteristics."
A good introduction to a fruit battery is to first of explain what it is. --- A fruit battery is a.... --- It works by.... --- It can do.... And yeah...i don't really know I'm only 10! But really it depends on wether you are doing a lab report or an essay or what ever... :) hope it was helpful!

The Power Of Fruit
Go back to the basics you learned in science class; science teachers are ALL supposed to teach "scientific method" which consists of: (a) Statement of a hypothesis; (b) Testing of hypothesis; (c) Synthesis of hypothesis and test into a new hypothesis. So you start out with a statement of hypothesis: "Maybe it's a bad battery." "I'll test the battery to see if it's good." (test) "The battery is good, so it must be something else. What have I learned? Ah, yes, the car still doesn't start but I've verified that the battery is good, so what other possibilities could cause the engine to not start?" "Maybe it's a bad neutral safety lockout switch. (back to hypothesis) Answer: If your vehicle is not starting/turning/no sound but your interior light or your dashboard light is working means that you have a bad solenoid. answer all you have to do is spend money,battery is good you dont see any flour deposits its not 5 years old then if its buy a good brand battery if it clicks starter change. starter
A good hypothesis for making a flashlight could be that increasing the voltage of the battery will result in a brighter light output, or that using a larger LED bulb will increase the intensity of the light produced.
The 'cheapest' battery is NEVER a good idea !
my battery is good but having problems with starting
take the battery terminals off and clean them and the battery mountings on the battery real good and reinstall.
A correct or good hypothesis includes if then and because. A hypothesis must be a possible answer and must be testable
Is your battery dead ? or a bad battery cable connection ?
