We insert copper and zinc electrodes in to the potato, close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we removed the shell of a broken AA battery for our Zinc electrode. Make sure to test your multimeter by connecting it's Positive and Negative wires to each other that should show no current and no voltage.
The balloon will grow as biogas is produced. You can test which types of biomass produce the most biogas by measuring out an equal amount of each of the following: The next time you help to clean out your refrigerator, you could find the perfect ingredients for your renewable energy science fair project!
The Energy in Peanuts Did you know that burning peanuts can produce energy as well? You can use this fact in a science project.
Dangle a tin can in the air; you can tie some string around its rim and suspend from the bottom of a kitchen cupboard so that it's hanging above a counter top. Add some water, and then place a burning peanut underneath it. You can keep the peanut safely standing by poking one end of a needle through a cork and the other through the peanut, and then set it on fire with adult supervision.
Measure the temperature increase of the water to show that the burning peanut is heating the water. For your science experiment, you may want to figure out which kind of nut will release the most energy when burned — a basic peanut?
A cashew or other type of nut? Make your hypothesis based on what you know about how potential energy is stored in foods, and then try an experiment to test it out.
Make Electricity from fruits. Make electricity science kit of ashio-midori.com contains all the above material: Opportunities for Science Fair Projects Experiment to see which fruits and liquids that you can find at home can produce enough electricity detectable by multi-meter. Science Pictures Potato battery science project. Potato battery science project is a simple experiment which demonstrates how a pair of different metals and electrolyte can produce electric current. Electricity Projects. Battery Life—A Science Experiment (By Tracy and Emily) Description: An experiment using the scientific method to determine which brand of battery lasts the longest. Lemon Power Description: Use a lemon to make a voltaic battery and even power a digital watch.
You can, however, explore different aspects of hydroelectric power. For example, why are water wheels placed so far below the surface of the water? You can figure this out by doing an experiment that shows whether deep water has more power than shallow water. To do this, poke two holes into a container, one near the bottom of the container, and one near the top of the container.
Tape over the two holes, and then fill the container with water. Remove one piece of tape, and measure the distance that the water travels. Then replace that piece of tape and remove the other one. Take a look at your results and think about what might have caused them and how the results can help you understand this aspect of water wheels.

Really Cool Science Project Idea #7 for Electricity This is a link to an idea for building your own metal detector. But, it’s perfect for static electricity science experiments! We did two experiments that quickly demonstrate the effects of static electricity in an exciting way.
Experiment #1: “Magically” Separate Pepper from Salt.
Step 1: Put some salt and pepper in a small dish. Stir it together.
