The Challenge of Asking Questions During this part of the lesson I have a good time working the room. Every time a student asks me a questions I offer praise for the question, and express my own feigned uncertainty as to the answer.

My daughter and I are doing the lemon battery experiment for a science prodject and are currently having trouble making it work.

Hooking the lemons together we were able to get 3. We purchased a number of items from "Radio Shack"whick ranged from lights 1. None of the items would work.

Who can edit: Lemon Battery Teacher Sheet Introduction Students should conduct the Lemon Battery experiment and then answer the questions that follow. If they need assistance answering the last three questions, they should go to the Lemon Battery experiment on the Hila Science Camp website at:

We tried adding three sets of three lemon cells together thinking this would provivide more current. We got a reading of 1. We connected the electrodes together with wire connectors alligator clip at each end,store bought.

Could you please tell me what we are doing wrong. What else could we use for electrodes? What are common items that are made from zinc or magnesium that could be used?

John - In order power a lightbulb, it needs to be provided with both voltage and current. As you've already checked the voltage across the lemons by using a voltmeter, you know that your setup is correct.

The important thing now is that you need to get more current. You've got the right idea by using cells of lemon batteries together. By connecting more of these cells in parallel, you can increase the current. By using more lemons in series in each cell, you can increase the voltage.

In order to check how much current you're getting, you'll need to use an ammeter. Your voltmeter probably has a setting which measures milliamps, and this will work for measuring current as well.

If it turns out that you're not getting enough current then you'll probably need to use even more lemons. The only other thing that may help beyond that is if you squish the lemons first so that they're really juicy inside.

This might help to increase the current that you get from each one. If the ammeter shows that you are getting enough current to run your lightbulb, then the problem is most likely to be in the lightbulb, not the battery. Make sure that you're attaching the wires to the lightbulb correctly, and check that the bulb isn't dead using a regular battery.

If the lightbulb still won't work, you should be able to power a small digital watch using several lemons. If you still can't get it to work, some other experiments along the same line of thought include touching your tongue to a wire attached to only one lemon battery.

Because the lemon produces such a small current, this won't hurt you, but you should be able to feel a tingle. Also, you should be able to hear a crackle inside the lemon if you put your ear up to it.

I've never actually tried this myself, but I've heard that it does work. Beyond that, I really don't know what to say. I also did this experiment but with potatos too. Although if you did want enough amperage, larger citrus fruits help and more fruit can increase it enough to power a light bulb - river age Hypothesis If a battery stores energy as a lemon stores juice and has space inside of it, then a lemon would be fifty percent (50%) better than a potato since a potato might provide a .

Note to students, teachers, and parents — The science fair projects and battery-powered electricity experiments you’ll find here introduce you to the foundations of portable power. Oct 02,  · For this science fair project, kids will learn how to make a lemon battery.

Generate Electricity with a Lemon Battery. A tingly science project from Science Buddies You can choose a different spot on the lemon you just used or use a second lemon to build a second battery. Lemon halves dipped in salt or baking powder can be used to brighten up copper and clean kitchenware.

An experiment that involves attaching electrodes to a lemon can create a battery that produces electricity. Several lemon batteries can power a small digital watch.
