Electricity

Give your class a magnetic charge with this creative experiment designed to teach emerging scientists about electromagnetism. Pupils construct a model that demonstrates the function of an electrical generator and test this creation in a...

Pupils test various materials to learn if the materials are conductors or insulators. They observe a small electric charge go through, or not go through, a material to light up a small bulb.

Learners examine how to make an electrical circuit. They listen to a teacher led discussion, design a switch to control a circuit, and construct a signaling device.

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

Combine geometry and tradition with a lesson that spotlights Navajo weaving. The book, The Goat in the Rug by Charles L. Blood and Martin Link hooks scholars before watching a video of Navajo people tending their sheep and beginning...

Human bodies can conduct electricity—that doesn't sound like it would feel good! Learners explore conductivity through the use of this simulation. They see why metals conduct electricity and plastics don't and why some materials will...

A sleepy-sounding narrator explains how batteries and circuits work. Simple computer animations display the movement of electrons through parallel and series circuits. Since the narrator speaks slowly and clearly, and the animations are...

Uncountable times every day "with the merest flick of a finger"each one of us calls on electricity to do our bidding. What would your life be like without electricity? Students begin learning about electricity with an introduction to the...

Students build their own simple conductivity tester and explore whether given solid materials and solutions are good conductors of electricity.

It is not as simple as scaling. MIT researchers explain that a micro engine cannot just be a proportional scaling of a working larger engine. The Math at the Core: Ratios resource compares the proportions involved with the surface area...
