Electricity becomes shocking in high school physics. Some physics projects give students control over this power of electric principles. Useful designs help discuss principles and visually display electricity. Sparks, shocks, strange effects and scary noises represent electrical high school physics projects. With the proper design, studying electricity becomes safe and educational.

This electric high school physics project displays the attractive principles of electrically charged objects. The most important principle to remember: opposite charges attract. Rub wool cloth several times over a rubber comb to generate a negative charge. Run tap water from a faucet and place the comb near running water. This causes the water to bend toward the comb. Water has a property called polarity and is related to pulling through electromagnetic forces. Polarity forces can cause magnetic-like attractions.
The ability to light a bulb without an electric plug is displayed in this high school physics project. Balloons allow charged particles to gather on the surface, and rubbing a balloon on wool or dry hair produces a static electric charge on the balloon. This charge causes attraction and repulsion with hair but also causes a discharge into a load. A neon light bulb shines faintly when placed close to a charged balloon. Get more charge on a balloon or charge several balloons and magically light a neon bulb without a cord.
Static Electric Generator
High school physics projects carefully determine procedures for repeatability and safety. Sparks generated from discharging static become a powerful tool for studying electric principles. Tape a styrofoam cup to the inside of an aluminium pie pan. Rub wool on a styrofoam plate and flip it over. Bring the pie pan close to the plate and discover what the styrofoam cup does. (Hint: if not holding the cup, the pie pan will spark immediately because the cup is a properly insulated handle.)
The Leyden jar represents a simple capacitor which is capable of holding electric charge and discharging it when desired. Puncture the lid of a small film canister with a nail. Take aluminium foil and wrap the bottom of the canister. Fill the canister with tap water. Charge a balloon by rubbing it with wool or dry hair, or use the charged pie pan from the previous project and sparks will arch from the nail when brought close. This drives electricity into the jar, or capacitor, which will discharge from the aluminium foil at the bottom.
