Draw a diagram of the way you wired the circuits. That means that the sunlight we see at this moment left the sun about 8 minutes ago. An atom is the basic unit of all elements. Everything on earth in made of elements. For example, water is made of two atoms of hydrogen and one atom of oxygen.
Electrons orbit around the center or nucleus of atoms.
When electricity contacts a conductor, it causes the electrons to move. The electrons don't move very far, just to the next atom, but the electric current travels at the speed of light. In good conductors, there is one electron that orbits very far from the nucleus. It's easy for this electron to move, making it easy for the electricity to pass through. When your bulb lights, slide one of the nails up and down in the water.
