The Science of Static Electricity - And Other Resources for Learning About Electricity

It is getting to be that time of year here in Maine when we can't walk across a carpet then touch a light switch without getting a bit of a shock. What causes that happen? And why does it seem to happen more often in the winter months than in the summer months? The answers to those questions and more are found in the TED-Ed lesson The Science of Static Electricity.



Other resources for teaching and learning about electricity.
Brain Stuff has a video that offers a good explanation of why we hear a buzzing sound coming from fluorescent lights found in many schools and office buildings. The video is embedded below.



Minute Physics offers a short video explaining how modern light bulbs work and how light bulb design has changed over the last 100+ years.The video also includes explanations of the different types of modern light bulbs and their applications. The video is embedded below.



Hydro to Home is an interactive story of hydro-electric power from raindrops to homes. The story walks visitors through each step of the process of generating hydro-electric power and delivering to consumers' homes. The story is narrated and along the way there are interactive images that visitors can click on to learn even more information about hydro-electric power.

The Blobz Guide to Electric Circuits is a neat series of interactive animations designed to help students of elementary and middle school age learn how electric circuits work. There are five sections to the series. Each sections builds upon the lessons of the previous section. The series starts with the basics of what makes a circuit complete and concludes with diagramming and building circuits. Each section in the series has a few short lessons and is followed by an animated interactive activity to which students can apply what they have just learned.
