Why study electricity? While it’s true that you don’t need to know how electricity works in order to flip on a light switch, but you do need to know a thing or two about circuits before you start wiring up your own robot. Electricity is all around you from the tiny subatomic level of the electron to the gigantic solar storms from the sun. When you’re done with this lesson, you’ll know how to wire up circuits for underwater vehicles, create your own robotics sensors, extract energy from fruit, split a water molecule, and really make sparks fly. Are you ready? This video will get you started on the right foot for your study into electricity:

The electrons orbit the nucleus as a cloud of particles spinning around, not around a fixed axis like a planet’s rings would. Here is a picture to help you see what this looks like, in a simplified way. The “spin” part is a way to think about it without getting too deep into the mechanics of particle physics.
Request for clarification: Lesson Plan for Unit 10 vocabulary states, “If an atom has more electrons spinning in one direction than in the other, that atom has a magnetic field.” Do you mean spinning on its axis or spinning around the nucleus? Thank you
