The cotton wash cloth did light up the tube, but it was faint and hard to see.Rub the different fabrics along the florescent light bulb tube until static electricity is built up to see if the light bulb will turn on or light up. Procedure: Do this project at night with all the lights off and record results with a camera or video camera. 2-3 scientists (one to rub the fabric on the light bulb, one to record the results on paper, one to record with camera or other device).Huggies disposable diaper will work (this was added just for fun at the end of the experiment).Mom’s 67% acrylic, 33% nylon sweater will work.Hypothesis: Some fabrics will work while others will not.
Purpose: To see which fabrics would produce enough static electricity to light up a fluorescent light bulb when said fabric is rubbed along the tube of the bulb.
So, he chose another project: Fluorescent Light Bulb Experiment that he wrote below: However, he realized that he did not have enough time to make the deadline- it’s an project he plans to work on over a longer period of time. His first thought was to his science experiment on growing pineapple. My son had the option of participating in a science fair for homeschoolers. for new experiments during Weather Education Week Home!

As a result, during thunderstorms, we always recommend you stay indoors where you’re safer from lightning.ĭid you try the experiment? We'd love to see a video! Parents, you can upload a video by clicking here. This can be dangerous! Lightning strikes the closest thing to the clouds, so taller trees or people in an open field will be the first conductor for the lightning to touch and release charge. The negative charge sends a bolt (an electrical current) down to the positively charged ground, striking things like powerlines or trees sometimes in the process. However, sometimes, the negative charge becomes too strong. Nature wants to balance, or to release this charge.Īir acts as an insulator, or protective barrier from the charge. The positive charge commonly rises to the tops of the clouds, while the negative charge sits on the bottom of the cloud, closest to us. When thunderstorms develop, the molecules in the cloud bounce off each other and build up a large charge. Lightning also follows the law of balance that caused our bulb to light up. With the transfer of electrons from the balloon, the gas can trigger a slightly brighter spark of light. When the electrons already inside the bulb are attracted toward the balloon, they may trigger the gas to glow and reflect inside the light bulb dimly. This experiment only works with a compact fluorescent bulb because they contain a gas inside the tube of the bulb. Finally, the negative charge jumps from the balloon to the bulb, discharging the electrons. At the same time, the pull of the static electricity attracts the negative charge inside the light bulb. So, when you put the light bulb close to the balloon, the static electricity moves toward the bulb. This is called static electricity.īecause nature seeks balance, the balloon does not want to maintain the additional negative charge! It wants to get rid of it. In this experiment, by rubbing the balloon on the wool sock or against the top of your head, you were creating an excess of negative charge (electrons). You lit the light bulb in a manner similar to how clouds create lightning! Nature likes for conditions to be balanced it likes positive (protons) and negative (electrons) charges to be able to mix and equalize.
