Veggie Power
To Whom It May Concern, veggie power science project, my 9 year old son whom is in 3rd grade is wanting to know how we can connect our veggie power to a light bulb instead of a calculator and what size LED light bulb should we use? Also, what is a "Resistor 10Kohm" ? We greatly appreciate any help we can get, this is his first project. I haven't had to work on a science project in many of years, I feel a bit lost, yet excited for him.
Sincerely, Alisa Alligood

Re: Veggie Power
Hello,
The vegetable battery is a classic project. A light bulb can be used rather than a calculator, though I would suggest using a tiny incandescent light bulb or "miniature lamp" rather than an LED since you can easily find one at a store like Radio Shack that lights at just 1.5 volts -what the procedure indicated the vegetable battery would provide. The resistor is used in Experiment 1 to show that adding resistance to the battery lowers the voltage read by the voltmeter. 10 kohm (kilo-ohm) simply refers to the amount of resistance it applies, and you can find a resistor at an electronics store as well. A resistor is necessary for Experiment 1 or other explorations of resistance but it is not necessary for creating the vegetable battery or powering the light.
I hope this helps, have fun working on this project with your son!

I noticed from your post that the final due date isn't for a few more weeks. I just thought I'd follow up and see how the experiment is going and if you had any additional questions.
Hope this helps.
