Which would be a better science project? A or B?

A) Get 3 small plants that are just babies and just starting to grow. To one of the plants, add some fertalizer ever day for a week. For another one of the plants add egg shells or bits of banana peels for a week and for the other do nothing but water and give it sun. Which plant should grow the most? How and why?

B) Using lemons, clips, zinc coated nails, pennies and a LED lightbulb, connect 4 peices of lemon together by connecting one end of the clip to the zinc nail (negative end) and the other end of the clip to the copper penny (positive end) once all of these are connected, the LED light should light up a bit. Using the acids in the lemon, you have created a battery using decomposable materials instead of energys, etc. If you do not fully understand this go to: http://ca.youtube.com/watch?v=oABk_KI5Ilo&feature=related Thanks for the help! =)

i would say both but if i had to choose one i would say b

The first one is easiest and everything you need is simple to get but the second one would look more impressive

want an A+??

then pick b
