Shake N' Light flashlights have been advertised on televisions across the nation in the recent year. But many do not understand just how they get energy to light up the bulb without using batteries. Do this experiment to make your own...

Through labs, readings, videos, and discussions, students learn about the concepts of Electromagnetic Induction.

Text and animated graphic show how lightning is an example of a natural capacitor.

Inside your brain, you have over 80 billion neurons - tiny brain cells, all working together to make you the person you are.Neurons talk to each other by sending electrical messages. Each message creates a tiny magnetic field. If enough...

Students face a game-like challenge to use electrostatic forces to move a charged puck into a goal. By placing charges on the rink, a charged puck can be attracted and repelled around obstacles and into a goal.

Learners will demonstrate how an electric current can make an iron object magnetic by building an electromagnet with a steel nail, insulated wire, a simple switch, a battery/cell, and small metal washers. Students predict the number of...

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...
