How Does the Foucault Pendulum Prove Earth's Rotation?
Did You Know? The Principia housed at the Oregon Convention Center is the world's largest Foucault pendulum. It comprises a 900-pound ball which is suspended using a 70-foot long cable. It swings continuously at a height of 20 feet over the heads of the visitors. Read more at Buzzle: http://www.buzzle.com/articles/how-does-the-foucault-pendulum-prove-earths-rotation.html
What Happens to a Current-Carrying Wire in a Magnetic Field?
Electric energy is carried by current, which is the flow of electrons, which are the negatively charged sub-particles of atoms. This transfer of electrons from one place to another powers our lights, phones, appliances and many other things we use...
How to Make a Simple Electric Motor
Energy comes in many forms. Electric energy can be converted into useful work, or mechanical energy, by machines called electric motors. Electric motors work due to electromagnetic interactions: the interaction of current (the flow of electrons)...
Renewable Energy Project for Kids: Power from Water
Energy can be made, or generated, using solids, gas or liquids as its source of power. So how do you use energy? Energy can be generated to produce light, heat or the movement of objects. In this experiment, we explore how to get power from water,...
