Hello SciFiJedi,
Before I suggest a title, I have some advice which might be helpful for your project.
When you state that you are testing electricity, you need to ask yourself how exactly are you planning to measure that. Though I might misunderstand your project's problem/question, it appears that you are wondering whether a lemon, copper wire, or penny
produce the most electricity. If so, you must understand that neither a copper wire nor a penny will "produce" electricity (although a lemon actually can). However, they might be able to
conduct electricity (stated simply, an object's electrical conductivity is how well it transfers/carries an electric charge). In other words, you might be able to use them as conductors for a source of electricity (such as a battery). You can then test which is the best conductor by determining which one among the lemon, copper wire, and penny results in the least amount of electrical resistance.
If you are comparing how well these objects conduct electricity (which might be the best option), then a catchy title would be "Conductivity Conundrum: Among Copper, Citrus, and Cents, Which One Best Conducts Electricity?"
Also, if you would like more detailed information on conductivity, current, and resistance, here are some helpful links:

Also, to measure voltage, current, or resistance, you will need a tool called a multimeter. Science Buddies has an article explaining how to use one:
