All matter is made up of tiny particles called __________________, which are made up of even tinier particles called protons, neutrons, and electrons. An _________________ is a particle with a negative charge which can move from atom to atom and from one object to another.

Question 2
2.
The number of electrons on the surface of an object can make it have a negative charge or a positive charge. If the surface has more electrons, the object is negatively charged (-). If the surface has fewer electrons, it has a positive charge (+). A negative charge can build up on an object when electrons move to it from another object. This build up of electric charge on an object is called ________________ ___________________ .

Question 6
6.
To be useful, electric energy must change into other forms of energy. Electrical energy can change into light, heat, sound, and motion. When you switch on a light, electric current flows through wires to the light bulb. The current causes a wire or gas inside the bulb to give off light. The bulb also gives off heat.
