Interested in learning more about energy through science experiments? Then check out the Energy Quest “Science Projects” page for lots of ideas and instructions! Energy Quest is the energy education website of the California Energy Commission.
This webpage offers a wide variety of science projects for people of all ages to do. To learn more, here is the list of Project Categories, with links to the individual sections. You’ll notice several renewable energy categories, such as solar, hydro-power, and geothermal, as well as “Saving Energy,” which is an important and environmentally-friendly principal.
Check out some of the projects below and let us know if you complete any of them!
A battery made from potatoes
Are you interested in science? How about renewable energy? If you said yes to either of these questions, you may enjoy some of these fun science fair projects, such as
making your own potato battery and solar water heater.
This potato battery can be used to power an alarm clock! The potato creates an electrochemical battery (or cell), which means it converts chemical energy into electric energy by a “spontaneous electron transfer.” As the experiment describes, “the potato acts as a sort of buffer between the zinc ions and copper ions” (from the nails and wire), allowing the electron transfer “to take place over the copper wires of the circuit, which channels the energy in the clock.”
This link shows you how to make a solar air heater, solar water heater, and a solar hot dog cooker. With materials like cardboard, scissors, string and paint, you can try to make these items and record your scientific observations in a genuine science experiment!
These projects could be very interesting as class projects, so consider asking your science teacher. If you decide to do any of the experiments, please make sure you take proper safety precautions, especially when dealing with electricity, and, if you are younger, that you have adult supervision. Let us know how they turn out – we may put up pictures on our Facebook page of your experiments!
